    Children with borderline intellectual functioning and autism spectrum disorder: developmental trajectories from 4 to 11 years of age2017Inngår i: Neuropsychiatric Disease and Treatment, ISSN 1176-6328, E-ISSN 1178-2021, Vol. 13, s. 2519-2526Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Studies on autism have tended to focus either on those with intellectual disability (ie, those with intellectual quotient [IQ] under 70) or on the group that is referred to as high-functioning, that is, those with borderline, average or above average IQ. The literature on cognition and daily functioning in autism spectrum disorder combined specifically with borderline intellectual functioning (IQ 70-84) is limited. Methods: From a representative group of 208 preschool children diagnosed with autism spectrum disorder, those 50 children in the group with borderline intellectual functioning at ages 4.5-6.5 years were targeted for follow-up at a median age of 10 years. A new cognitive test was carried out in 30 children. Parents were interviewed with a semi-structured interview together with the Vineland Adaptive Behavior Scales (n=41) and the Autism-Tics, attention-deficit/hyperactivity disorder (AD/HD) and other comorbidities inventory (A-TAC) (n=36). Results: Most children of interviewed parents presented problems within several developmental areas. According to A-TAC and the clinical interview, there were high rates of attention deficits and difficulties with regulating activity level and impulsivity. Vineland Adaptive Behavior Scales composite scores showed that at school age, a majority of the children had declined since the previous assessment at ages between 4.5 and 6.5 years. Almost half the tested group had shifted in their IQ level, to below 70 or above 84. Conclusion: None of the children assessed was without developmental/neuropsychiatric problems at school-age follow-up. The results support the need for comprehensive follow-up of educational, medical and developmental/neuropsychiatric needs, including a retesting of cognitive functions. There is also a need for continuing parent/family follow-up and support.

    Second Language Ability and Emotional Prosody Perception2016Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 11, nr 6, artikkel-id e0156855Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The present study examines the effect of language experience on vocal emotion perception in a second language. Native speakers of French with varying levels of self-reported English ability were asked to identify emotions from vocal expressions produced by American actors in a forced-choice task, and to rate their pleasantness, power, alertness and intensity on continuous scales. Stimuli included emotionally expressive English speech (emotional prosody) and non-linguistic vocalizations (affect bursts), and a baseline condition with Swiss-French pseudo-speech. Results revealed effects of English ability on the recognition of emotions in English speech but not in non-linguistic vocalizations. Specifically, higher English ability was associated with less accurate identification of positive emotions, but not with the interpretation of negative emotions. Moreover, higher English ability was associated with lower ratings of pleasantness and power, again only for emotional prosody. This suggests that second language skills may sometimes interfere with emotion recognition from speech prosody, particularly for positive emotions.

    Regulation of Experienced and Anticipated Regret in Daily Decision Making2016Inngår i: Emotion, ISSN 1528-3542, E-ISSN 1931-1516, Vol. 16, nr 3, s. 381-386Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Decisions were sampled from 108 participants during 8 days using a web-based diary method. Each day participants rated experienced regret for a decision made, as well as forecasted regret for a decision to be made. Participants also indicated to what extent they used different strategies to prevent or regulate regret. Participants regretted 30% of decisions and forecasted regret in 70% of future decisions, indicating both that regret is relatively prevalent in daily decisions but also that experienced regret was less frequent than forecasted regret. In addition, a number of decision-specific regulation and prevention strategies were successfully used by the participants to minimize regret and negative emotions in daily decision making. Overall, these results suggest that regulation and prevention of regret are important strategies in many of our daily decisions.

    Long-Term Cognitive Functioning and Psychological Well-Being in Surgically Treated Patients with Low-Grade Glioma2017Inngår i: World Neurosurgery, ISSN 1878-8750, E-ISSN 1878-8769, Vol. 103, s. 799-808.e9Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: The aim of this work is to provide an in-depth investigation of the impact of low-grade gliomas (LGG) and their surgery on patients' cognitive and emotional functioning and well-being, carried out via a comprehensive and multiple-measure psychological and neuropsychological assessment.

    Patients and Methods: Fifty surgically treated patients with LGG were evaluated 40 months after surgery on their functioning over 6 different cognitive domains, 3 core affective/emotional aspects, and 3 different psychological well-being measures to obtain a clearer picture of the long-term impact of illness and surgery on their psychological and relational world. Close relatives were also involved to obtain an independent measure of the psychological dimensions investigated.

    Results: Cognitive status was satisfactory, with only mild short-term memory difficulties. The affective and well-being profile was characterized by mild signs of depression, good satisfaction with life and psychological well-being, and good personality development, with patients perceiving themselves as stronger and better persons after illness. However, patients showed higher emotional reactivity, and psychological well-being measures were negatively affected by epileptic burden. Well-being was related to positive affective/emotional functioning and unrelated to cognitive functioning. Good agreement between patients and relatives was found.

    Conclusions: In the long-term, patients operated on for LGG showed good cognitive functioning, with no significant long-term cognitive sequelae for the extensive surgical approach. Psychologically, patients appear to experience a deep psychological change and maturation, closely resembling that of so-called posttraumatic growth, which, to our knowledge, is for the first time described and quantified in patients with LGG.

    Prenatal ultrasound and childhood autism: long-term follow-up after a randomized controlled trial of first- vs second-trimester ultrasound2016Inngår i: Ultrasound in Obstetrics and Gynecology, ISSN 0960-7692, E-ISSN 1469-0705, Vol. 48, nr 3, s. 285-288Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To analyze whether the frequency of autism spectrum disorder (ASD) in a cohort of Swedish children differs between those exposed to ultrasound in the 12th week and those exposed to ultrasound in the 18th week of gestation.

    Methods: The study cohort consisted of approximately 30 000 children born between 1999 and 2003 to mothers who had been randomized to a prenatal ultrasound examination at either 12 or 18weeks' gestation as part of the framework for a study on nuchal translucency screening. The outcome measure in the present study was the rate of ASD diagnoses among the children. Information on ASD diagnoses was based on data from the Swedish social insurance agency concerning childcare allowance granted for ASD.

    Results: Between 1999 and 2003, a total of 14 726 children were born to women who underwent a 12-week ultrasound examination and 14 596 to women who underwent an 18-week ultrasound examination. Of these, 181 (1.2%) and 176 (1.2%) children, respectively, had been diagnosed with ASD. There was no difference in ASD frequency between the early and late ultrasound groups.

    Conclusions: Women subjected to at least one prenatal ultrasound examination at either 12 or 18weeks' gestation had children with similar rates of ASD. However, this result reflects routine care 10-15 years ago in Sweden. Today, higher intensity ultrasound scans are performed more frequently, at earlier stages during pregnancy and for non-medical purposes, implying longer exposure time for the fetus. This change in the use of ultrasound necessitates further follow-up study of the possible effects that high exposure to ultrasound during the gestational period has on the developing brain.

    Affected by Smells?: Environmental Chemical Responsivity Predicts Odor Perception2011Inngår i: Chemical Senses, ISSN 0379-864X, E-ISSN 1464-3553, Vol. 36, nr 7, s. 641-648Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Strong negative reactions, physical symptoms, and behavioral disruptions due to environmental odors are common in the adult population. We investigated relationships among such environmental chemosensory responsivity (CR), personality traits, affective states, and odor perception. Study 1 showed that CR and neuroticism were positively correlated in a sample of young adults (n = 101), suggesting that persons high in neuroticism respond more negatively to environmental odors. Study 2 explored the relationships among CR, noise responsivity (NR), neuroticism, and odor perception (i.e., pleasantness and intensity) in a subset of participants (n = 40). High CR was associated with high NR. Regression analyses indicated that high CR predicted higher odor intensity ratings and low olfactory threshold (high sensitivity) predicted lower pleasantness ratings. However, neuroticism was not directly associated with odor ratings or thresholds. Overall, the results suggest that CR and odor thresholds predict perceptual ratings of odors and that high CR is associated with nonchemosensory affective traits.

    Long-Term Memory for Odors: Influences of Familiarity and Identification Across 64 Days2015Inngår i: Chemical Senses, ISSN 0379-864X, E-ISSN 1464-3553, Vol. 40, nr 4, s. 259-267Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Few studies have investigated long-term odor recognition memory, although some early observations suggested that the forgetting rate of olfactory representations is slower than for other sensory modalities. This study investigated recognition memory across 64 days for high and low familiar odors and faces. Memory was assessed in 83 young participants at 4 occasions; immediate, 4, 16, and 64 days after encoding. The results indicated significant forgetting for odors and faces across the 64 days. The forgetting functions for the 2 modalities were not fundamentally different. Moreover, high familiar odors and faces were better remembered than low familiar ones, indicating an important role of semantic knowledge on recognition proficiency for both modalities. Although odor recognition was significantly better than chance at the 64 days testing, memory for the low familiar odors was relatively poor. Also, the results indicated that odor identification consistency across sessions, irrespective of accuracy, was positively related to successful recognition.

    Intranasal Oxytocin and Response Inhibition in Young and Older Adults2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In normal aging, people are confronted with impairment in both socioemotional and cognitive abilities. Specifically, there are age-related declines in inhibitory processes that regulate attention towards irrelevant material. In last years, the intranasal administration of the neuropeptide oxytocin has mainly been related to improvements in several domains such as emotion recognition and memory, but to date the effects of oxytocin in aging remain largely unknown. In a randomized, double blind, placebo controlled, within-subjects study design, we investigated whether oxytocin facilitates inhibitory processing in older adults compared to younger adults. In total, 41 older adults (51% women; age range 65-75 years) and 37 younger adults (49% women; age range 20-30 years) participated in this study two times, receiving a single intranasal dose of 40 IU of placebo and oxytocin in randomized order 45 minutes before engaging in the task. Participants were tested approximately a month apart and mostly at the same hour during both occasions. Inhibition was measured with a Go/NoGo task which included happy and neutral faces as targets (Go stimuli) and distractors (NoGo stimuli) shown on a computer screen. Participants were instructed to press a button any time they saw a target and remain passive when encountering a distractor. Preliminary results indicate effects for happy and neutral faces, but only in the distractor condition. For happy distractors, women rejected correctly happy faces more accurately than men did, both in the placebo and oxytocin conditions. A main effect of age was observed for the neutral distractors, where older adults were more successful in inhibiting responses than younger adults during oxytocin and placebo treatments. We did not observe effects of oxytocin in the different tasks. The role of oxytocin was not clear distinguished in the tasks. In sum, our findings showed that age and gender can influence inhibition but their effects depend on the displayed emotions. This suggests that the ability to inhibit interfering distractors may remain intact despite of age and that deficits in inhibition may be selective. The role of oxytocin in inhibition needs to be further investigated since it is possible that it is context dependent.

    Age differences in judgments of attractiveness, likeability, and trustworthiness of faces2016Inngår i: Program of SANS 2016, 2016, s. 58-58, artikkel-id B-23Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    People constantly evaluate faces to obtain social information. However, the link between aging and social evaluation of faces is not well understood. Todorov and colleagues introduced a data-driven model defined by valence and dominance as the two main components underlying social judgments of faces. They also created a stimulus set consisting of computer-generated faces which systematically vary along various social dimensions (e.g., Todorov et al., 2013, Emotion, 13, 724-38). We utilized a selection of these facial stimuli to investigate age-related differences in judgments of the following dimensions: attractiveness, competence, dominance, extraversion, likeability, threat, and trustworthiness. Participants rated how well the faces represented the intended social dimensions on 9-point scales ranging from not at all to extremely well. Results from 71 younger (YA; mean age = 23.42 years) and 60 older adults (OA; mean age = 69.19 years) showed that OA evaluated untrustworthy faces as more trustworthy, dislikeable faces as more likeable, and unattractive faces as more attractive compared to YA. OA also evaluated attractive faces as more attractive compared to YA, whereas YA did rate likeable and trustworthy faces as more likeable and trustworthy than did OA. In summary, our findings showed that OA evaluated negative social features less negatively compared to YA. This suggests that older and younger persons may use different cues for social evaluation of faces, and is in line with prior research suggesting age-related decline in the ability to recognize negative emotion expressions.

    Memory for faces and voices varies as a function of sex and expressed emotion2017Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, nr 6, artikkel-id e0178423Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We investigated how memory for faces and voices (presented separately and in combination) varies as a function of sex and emotional expression (anger, disgust, fear, happiness, sadness, and neutral). At encoding, participants judged the expressed emotion of items in forced-choice tasks, followed by incidental Remember/Know recognition tasks. Results from 600 participants showed that accuracy (hits minus false alarms) was consistently higher for neutral compared to emotional items, whereas accuracy for specific emotions varied across the presentation modalities (i.e., faces, voices, and face-voice combinations). For the subjective sense of recollection (“remember” hits), neutral items received the highest hit rates only for faces, whereas for voices and face-voice combinations anger and fear expressions instead received the highest recollection rates. We also observed better accuracy for items by female expressers, and own-sex bias where female participants displayed memory advantage for female faces and face-voice combinations. Results further suggest that own-sex bias can be explained by recollection, rather than familiarity, rates. Overall, results show that memory for faces and voices may be influenced by the expressions that they carry, as well as by the sex of both items and participants. Emotion expressions may also enhance the subjective sense of recollection without enhancing memory accuracy.

    Single-dose intranasal oxytocin administration induces brain activity reductions to negative socioemotional stimuli in younger and older adults2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Findings suggest that intranasal administration of oxytocin improves emotion recognition. The brain mechanisms underlying these effects, however, are underexplored. A major caveat in this line of work is that it is almost exclusively based on young males, which limits current knowledge and potential for generalizability across gender and age. Adopting an adult developmental approach, the present research addresses this research gap by determining the effects of a single-dose intranasal oxytocin administration on recognition of positive and negative stimuli in younger and older men and women. Utilizing a randomized, double-blind, placebo-controlled, within-subjects study design, 44 younger (mean age 25, 50% women) and 44 older (mean 70, 50% women) healthy adults participated in two fMRI sessions during which they viewed dynamic videoclips of positive and negative emotions displayed. Forty minutes before scanning, participants either self-administered 40 IUs of oxytocin or placebo.

    Glaucoma Surgery Outcome in Rwanda2016Inngår i: Journal of glaucoma, ISSN 1057-0829, E-ISSN 1536-481X, Vol. 25, nr 8, s. 698-703Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: To assess long-term intraocular pressure (TOP) outcome after adult trabeculectomy surgery in Central Africa. Patients and Methods: All adult glaucoma patients who underwent trabeculectomy surgery in the Kabgayi Eye Unit, Rwanda between August 2003 and March 2008 were invited for a follow-up visit. Surgical and clinical data were collected from medical records. At the study visit, best-corrected visual acuity was measured and Goldmann applanation tonometry and biomicroscopy were done. Good IOP outcome was defined as both an IOP < 21 mm Hg and achieving >= 30% reduction from the preoperative IOP. Considering first operated eyes, univariate and multivariate logistic regression was used to investigate risk factors for failure. Results: Of 163 individuals operated 3 had died, 118 (74%) participated. Preoperatively, the mean IOP was 31 mm Hg (SD = 11; range, 12 to 60). At the time of the follow-up study visit the mean postoperative IOP was 13 mm Hg (SD = 5; range, 4 to 35). Good IOP outcome was achieved in 132 eyes (84%). Univariate analysis suggested a protective effect against failure of use of anti metabolites [odds ratio (OR) = 0.39; 95% confidence interval (CI), 0.14-1.11; P = 0.07] and a decrease in success with length of follow-up (OR = 3.57; 95% CI, 1.09-12.50; P = 0.03). The latter remained borderline significant with multivariate analysis. Seven eyes went from previously better vision (at least hand movements) down to perception of light or no perception of light after trabeculectomy. Particularly a flat anterior chamber in the first postoperative week (OR = 0.07; 95% CI, 0.01-0.49; P < 0.001) and late hypotony (OR = 0.04; 95% CI, 0.002-0.99; P = 0.004) were significant risk factors for severe visual loss. Conclusions: Trabeculectomy with antimetabolites is one of the best available options for glaucoma management in Africa. However, the IOP control reduced at a follow-up duration beyond 2 years, highlighting the importance of regular long-term follow-up.

    Multiple routes from memory to decision making2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    We present two individual-differences investigations, carried out with the aim of identifying the memory correlates of decision-making skills. The investigations were carried out on population-based Swedish samples between 25 and 80 years of age (n > 500). Study 1 showed selective relations between memory processes (i.e., semantic, episodic, and working memory) and diverse aspects of decision-making competence as measured with the A-DMC battery. The age-related declines observed in the more cognitively-demanding decision-making tasks were mediated by the age-related differences in working memory or episodic memory. Study 2 confirmed the findings even when controlling for the influence of processing speed and sensory functioning. Overall, the results showed that different memory processes fulfill different functional roles in diverse judgment and decision-making tasks.

    Unraveling the Aging Skein: Disentangling Sensory and Cognitive Predictors of Age-related Differences in Decision Making2017Inngår i: Journal of Behavioral Decision Making, ISSN 0894-3257, E-ISSN 1099-0771, Vol. 30, nr 1, s. 123-139Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Age-related differences in sensory functioning, processing speed, and working memory have been identified as three significant predictors of the age-related performance decline observed in complex cognitive tasks. Yet, the assessment of their relative predictive capacity and interrelations is still an open issue in decision making and cognitive aging research. Indeed, no previous investigation has examined the relationships of all these three predictors with decision making. In an individual-differences study, we therefore disentangled the relative contribution of sensory functioning, processing speed, and working memory to the prediction of the age-related decline in cognitively demanding judgment and decision-making tasks. Structural equation modeling showed that the age-related decline in working memory plays an important predictive role, even when controlling for sensory functioning, processing speed, and education. Implications for research on decision making and cognitive aging are discussed.

    Predictors of Decision Making Across the Adult Life-Span: An Individual-Differences Study2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Age-related decline in complex cognitive tasks has been explained by changes in sensory functioning, processing speed, and working memory. However, there is still no agreement on the relative importance of these factors, and their relative role in decision making has not been investigated. In an individual-difference study on a population-based Swedish sample of adults (N = 563, age range 30-89), we disentangled the contribution of sensory decline, processing speed, and working memory measures to age-related changes in three cognitively-demanding decision-making tasks of the Adult Decision-Making Competence Battery (Resistance to Framing, Applying Decision Rules, Under/Overconfidence). Structural equation modeling showed that working memory is a significant predictor even when the influence of sensory variables, processing speed, and education (as a control for cohort effects) is taken into account. Moreover, the effects of sensory functioning and processing speed on decision making were mediated by working memory. These findings indicate that the age-related decline in complex decision-making tasks may not be entirely explained by changes in lower-level processes, highlighting the functional role of working memory processes.

    Perceived inflation: The role of product accessibility and attitudes towards inflation2016Inngår i: Journal of Economic Psychology, ISSN 0167-4870, E-ISSN 1872-7719, Vol. 56, s. 97-106Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Little is known about the psychological mechanisms underlying judgments of perceived inflation as empirical evidence is sparse. In two studies, we investigated two factors that are expected to play a significant role in global judgments of perceived inflation: product accessibility and attitudes towards inflation. In Study 1 (N = 253), primed participants retrieved five products whose prices had increased (or decreased) in the past year before expressing a judgment of past inflation (versus non-primed participants with no retrieval task). In Study 2 (N = 101) participants were merely exposed to a series of products, and asked to estimate their frequency of purchase, before judging past inflation. In one condition, the prices of the majority of products had actually increased in the last year, while in another condition they had decreased. In both studies, attitudes towards inflation were also measured. Product priming consistently affected inflation judgments in the direction of an assimilation effect. Also, more negative attitudes towards inflation were associated with higher judgments of perceived inflation. Path analysis confirmed that both product accessibility and attitudes are potential bases for judgments of perceived inflation. These findings suggest that multiple psychological influences may underlie global judgments of perceived inflation.

    Smell Loss Predicts Mortality Risk Regardless of Dementia Conversion2017Inngår i: Journal of The American Geriatrics Society, ISSN 0002-8614, E-ISSN 1532-5415, Vol. 65, nr 6, s. 1238-1243Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives

    To determine whether dementia could explain the association between poor olfactory performance and mortality risk within a decade-long follow-up period.

    Design

    Prospective cohort study.

    Setting

    Betula Study, Umeå, Sweden.

    Participants

    A population-based sample of adult participants without dementia at baseline aged 40 to 90 (N = 1,774).

    Measurements

    Olfactory performance using the Scandinavian Odor-Identification Test (SOIT) and self-reported olfactory function; several social, cognitive, and medical risk factors at baseline; and incident dementia during the following decade.

    Results

    Within the 10-year follow-up, 411 of 1,774 (23.2%) participants had died. In a Cox model, the association between higher SOIT score and lower mortality was significant (hazard ratio (HR) = 0.74 per point interval, 95% confidence interval (CI) = 0.71-0.77, P < .001). The effect was attenuated, but remained significant, after controlling for age, sex, education, and health-related and cognitive variables (HR = 0.92, 95% CI = 0.87-0.97, P = .001). The association between SOIT score and mortality was retained after controlling for dementia conversion before death (HR = 0.92, 95% CI = 0.87-0.97, P = .001). Similar results were obtained for self-reported olfactory dysfunction.

    Conclusion

    Poor odor identification and poor self-reported olfactory function are associated with greater likelihood of future mortality. Dementia does not attenuate the association between olfactory loss and mortality, suggesting that olfactory loss might mark deteriorating health, irrespective of dementia.

    Emotion recognition deficits among persons with schizophrenia: Beyond stimulus complexity level and presentation modality2016Inngår i: Psychiatry Research, ISSN 0165-1781, E-ISSN 1872-7123, Vol. 240, s. 60-65Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Studies have shown that persons with schizophrenia have lower accuracy in emotion recognition compared to persons without schizophrenia. However, the impact of the complexity level of the stimuli or the modality of presentation has not been extensively addressed. Forty three persons with a diagnosis of schizophrenia and 43 healthy controls, matched for age and gender, were administered tests assessing emotion recognition from stimuli with low and high levels of complexity presented via visual, auditory and semantic channels. For both groups, recognition rates were higher for high-complexity stimuli compared to low-complexity stimuli. Additionally, both groups obtained higher recognition rates for visual and semantic stimuli than for auditory stimuli, but persons with schizophrenia obtained lower accuracy than persons in the control group for all presentation modalities. Persons diagnosed with schizophrenia did not present a level of complexity specific deficit or modality-specific deficit compared to healthy controls. Results suggest that emotion recognition deficits in schizophrenia are beyond level of complexity of stimuli and modality, and present a global difficulty in cognitive functioning.

    Genetic and Environmental Influences on Longitudinal Trajectories of Functional Biological Age: Comparisons Across Gender2017Inngår i: Behavior Genetics, ISSN 0001-8244, E-ISSN 1573-3297, Vol. 47, nr 4, s. 375-382Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We used an alternate age variable, functional biological age (fBioAge), which was based on performance on functional body measures. The aim was to examine development of fBioAge across the adult life span, and to also examine potential gender differences and genetic and environmental influences on change with age. We used longitudinal data (n = 740; chronological age (ChronAge) range 45-85 at baseline) from the Swedish Adoption/Twin Study of Aging. The rate of increase in fBioAge was twice as fast after ChronAge 75 than before. fBioAge was higher in women than in men. fBioAge was fairly equally influenced by genetic and environmental factors. Whereas the rate of ChronAge cannot vary across time, gender, or individual, our analyses demonstrate that fBioAge does capture these within and between individual differences in aging, providing advantages for fBioAge in the study of aging effects.

    A network of synaptic genes associated with schizophrenia and bipolar disorder2016Inngår i: Schizophrenia Research, ISSN 0920-9964, E-ISSN 1573-2509, Vol. 172, nr 1-3, s. 68-74Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Identification of novel candidate genes for schizophrenia (SZ) and bipolar disorder (BP), two psychiatric disorders with large epidemiological impacts, is a key research area in neurosciences and psychiatric genetics. Previous evidence from genome-wide studies suggests an important role for genes involved in synaptic plasticity in the risk for SZ and BP. We used a convergent genomics approach, combining different lines of biological evidence, to identify genes involved in the cAMP/PKA/CREB functional pathway that could be novel candidates for BP and SZ: CREB1, CREM, GRIN2C, NPY2R, NF1, PPP3CB and PRKAR1A. These 7 genes were analyzed in a HapMap based association study comprising 48 common SNPs in 486 SZ, 351 BP patients and 514 control individuals recruited from an isolated population in Northern Sweden. Genetic analysis showed significant allelic associations of SNPs in PRKAR1A with SZ and of PPP3CB and PRKAR1A with BP. Our results highlight the feasibility and the importance of convergent genomic data analysis for the identification of candidate genes and our data provide support for the role of common inherited variants in synaptic genes and their involvement in the etiology of BP and SZ.

    Why do General Practitioners Self-Diagnose and Self-Prescribe Drugs?2016Inngår i: Book of Proceedings. 12th Conference of the European Academy of Occupational Health Psychology: OHP in Times of Change: Society and the workplace / [ed] K. Teoh, V. Dediu, N.J. Saade, & J. Hassard, Nottingham, UK, 2016, s. 203-203Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Objective: Physicians tend to demonstrate inappropriate behavior when it comes to taking care of their own health. Self-prescribing or self-treatment seems to be practiced in many countries, and self-treated illnesses are found to be more common among general practitioners. For the physician such behavior is a threat to their own health, and as a consequence their patients might not be able to receive optimal health care. The purpose of this study is to examine the relationship between help seeking behavior, sickness presenteeism, exhaustion, and self- treatment among general practitioners.

    Method: This cross-sectional study was conducted in 2013 among GPs employed in one City Council in Sweden using a questionnaire on health and work factors. The criterion variable “To self-diagnose and self-treat” was measured with a single item from the Physician Career Path Questionnaire (PCPQ; Fridner, 2004). Exhaustion was measured with a scale from the Oldenburg Burnout Inventory, OLBI (α = .82; Demerouti et al., 2001, 2003). “Sickness presenteeism” and “Taking vacation due to stress” was measured with single items, also from the PCPQ (Fridner, 2004). For the analyses, we used hierarchical multiple regression.

    Results: Altogether 193 (63,9%) female GPs and 109 (36,1%) male GPs answered the questionnaire, a 44% response-rate. Among them 46,2% stated they had diagnosed and treated themselves for a condition for which they would have referred a patient to a specialist. Our regression analysis model revealed that those physicians who self-treated themselves were also significantly more sickness present at work. Adding to this, exhaustion among the GPs was also included in the model.

    Conclusions: This study shows that self-treatment is not an isolated behavior, but occurs together with exhaustion and sickness presenteeism, indicating a quite severe situation for their health, which would need to be investigated by other doctors than themselves. This needs to be further investigated and taken into account by the National Board of Health and Welfare, County Councils and Medical Associations, and for future physicians our medical schools.

    Different investors–different decisions: On individual use of gain, loss and interest rate information2017Inngår i: Journal of Behavioral and Experimental Finance, ISSN 2214-6350, E-ISSN 2214-6369, Vol. 15, s. 59-65Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study investigated how accumulating gains and losses, described as annual interest rates, influenced investment behavior. Investments after gains were on average greater than after losses regardless of the gain and loss interest rates. However, greater variance of interest rates gave some weight to that variable for gains but not for losses. We also analyzed the influence from different information cues on each participant’s investments. This revealed that interest rates influenced participants very differently, some invested more with increasing gains, or with increasing losses, while others invested less. This finding explained why interest rate was a weak predictor on the group level. Furthermore, our individual analyses showed an increased sensitivity to interest rates and judged future asset accumulations when the interest rate variance was greater. Finally, subjective reports of the importance of different cues for the participants’ own investments showed only some understanding of the cues influence on the investments.

    Gender differences in Reasons for Sickness Presenteeism - a study among GPs in a Swedish health care organization2016Inngår i: Annals of Occupational and Environmental Medicine, ISSN 2052-4374, Vol. 28, artikkel-id 50Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: It is common that physicians go to work while sick and therefore it is important to understand the reasons behind. Previous research has shown that women and men differ in health and health related behavior. In this study, we examine gender differences among general practitioners who work while sick.

    Methods: General practitioners (GP’s) working in outpatient care in a Swedish city participated in the study (n = 283; women = 63 %; response rate = 41 %). Data were obtained from a large web-based questionnaire about health and organization within primary care. Two questions about sickness presenteeism (going to work while sick) were included; life-long and during the past 12 months, and five questions about reasons. We controlled for general health, work-family conflict and demographic variables.

    Results: Female physicians reported sickness presenteeism more often than male physicians. Work-family conflict mediated the association between gender and sickness presenteeism.

    Women reported reasons related with “concern for others” and “workload” more strongly than men. Men reported reasons related with “capacity” and “money” more strongly than women. These differences are likely effects of gender stereotyping and different family-responsibilities.

    Conclusions: Gender socialization and gender stereotypes may influence work and health-related behavior. Because sickness presenteeism is related with negative effects both on individuals and at organizational levels, it is important that managers of health organizations understand the reasons for this, and how gender roles may influence the prevalence of sickness presenteeism and the reasons that female and male GPs give for their behavior.

    Age-Related Olfactory Decline is Associated with the BDNF Val66met Polymorphism: Evidence from a Population-Based Study2010Inngår i: Frontiers in Aging Neuroscience, ISSN 1663-4365, Vol. 2, nr 7, s. 24-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The present study investigates the effect of the brain-derived neurotrophic factor (BDNF) val66met polymorphism on change in olfactory function in a large scale, longitudinal population-based sample (n = 836). The subjects were tested on a 13 item force-choice odor identification test on two test occasions over a 5-year-interval. Sex, education, health-related factors, and semantic ability were controlled for in the statistical analyses. Results showed an interaction effect of age and BDNF val66met on olfactory change, such that the magnitude of olfactory decline in the older age cohort (70–90years old at baseline) was larger for the val homozygote carriers than for the met carriers. The older met carriers did not display larger age-related decline in olfactory function compared to the younger group. The BDNF val66met polymorphism did not affect the rate of decline in the younger age cohort (45–65years). The findings are discussed in the light of the proposed roles of BDNF in neural development and maintenance.

    Young pain patients’ experience in primary care: A qualitative study2017Inngår i: Nordic Psychology, ISSN 1901-2276, E-ISSN 1904-0016, Vol. 69, nr 2, s. 83-99Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose was to explore interview data from young adults with long-standing pain about their experience of contacts with caregivers in a primary care setting, in order to synthesize and qualitatively analyse their reports about how they were received. Method: An emergent qualitative design was used. Open thematic research interviews were conducted with 11 young people (1 man, 10 women) (aged 20–31 years) with long-term pain. The interviews were recorded, transcribed verbatim and analysed using inductive thematic content analysis. Result: The analyses resulted in three themes; distrust experienced from care staffslonelinessand hopelessness forming the main theme Young adult with long-term pain. The informants described how they struggled with living with the pain, fighting with the care system and to obtain help. They reportedly felt they were not trusted and that they were not given any explanations or information why the pain spread and worsened. This left them feeling abandoned and alone and without hope concerning their pain, their feelings; and with doubts concerning their prospects. Much concern and doubt were expressed about their future work situation; whether they would be able to do work for which they had trained, and whether they would ever get any career opportunities. Conclusion: Living with long-term pain as a young adult and experiencing mistrust when in care might lead to feelings of loneliness, dependence and hopelessness and an existence marked by suffering and dependence. The experienced mistrust confined the young adult instead of allowing growth towards an adult identity and opportunities.

    Multimodal Emotion Recognition Is Resilient to Insufficient Sleep: Results From Cross-Sectional and Experimental Studies2017Inngår i: Sleep, ISSN 0161-8105, E-ISSN 1550-9109, Vol. 40, nr 11, artikkel-id zsx145Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: Insufficient sleep has been associated with impaired recognition of facial emotions. However, previous studies have found inconsistent results, potentially stemming from the type of static picture task used. We therefore examined whether insufficient sleep was associated with decreased emotion recognition ability in two separate studies using a dynamic multimodal task.

    Methods: Study 1 used a cross-sectional design consisting of 291 participants with questionnaire measures assessing sleep duration and self-reported sleep quality for the previous night. Study 2 used an experimental design involving 181 participants where individuals were quasi-randomized into either a sleep-deprivation (N = 90) or a sleep-control (N = 91) condition. All participants from both studies were tested on the same forced-choice multimodal test of emotion recognition to assess the accuracy of emotion categorization.

    Results: Sleep duration, self-reported sleep quality (study 1), and sleep deprivation (study 2) did not predict overall emotion recognition accuracy or speed. Similarly, the responses to each of the twelve emotions tested showed no evidence of impaired recognition ability, apart from one positive association suggesting that greater self-reported sleep quality could predict more accurate recognition of disgust (study 1).

    Conclusions: The studies presented here involve considerably larger samples than previous studies and the results support the null hypotheses. Therefore, we suggest that the ability to accurately categorize the emotions of others is not associated with short-term sleep duration or sleep quality and is resilient to acute periods of insufficient sleep.

    Total sleep deprivation does not impact emotioncategorisation in dynamic stimuli2016Inngår i: Abstracts of the 23rd Congress of the European Sleep Research Society, 13–16 September 2016, Bologna, Italy. Journal of Sleep Research, 2016, Vol. 25(S1), s. 152-152, artikkel-id P193Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Previous studies have highlighted a deficit in facial emotion recognition after sleep loss. However, while some studies suggest an overall deficit in ability, others have only found effects in individual emotions, or no effect at all. The aim of this study was to investigate this relationship in a large sample and to utilise a dynamic test of emotion recognition in multiple modalities. 145 individuals (91 female, ages 18–45) participated in a sleep-deprivation experiment. Participants were randomised into: one night of total sleep deprivation (TSD) or normal sleep (8–9 h in bed). The following day participants completed a computerised emotional recognition test, consisting of 72 visual, audio, and audio-visual clips, representing 12 different emotions. The stimuli were divided into “easy” and “hard” depending on the intensity of emotional display. A mixed ANOVA revealed significant main effects of modality and difficulty, P < 0.001, but no main effect of condition, P = 0.31, on emotional recognition accuracy. Additionally, there was no interaction between condition and difficulty, P = 0.96, or modality, P = 0.67. This study indicates that sleep deprivation does not reduce the ability to recognise emotions. Given that some studies have only found effects on single emotions, it is possible that the effects of sleep loss are more specific than investigated here. However, it is also possible that previous findings relate to the types of static stimuli used. The ability to recognise emotions is key to social perception; this study suggests that this ability is resilient to one night of sleep deprivation.

    Emotion recognition associated with polymorphism in oxytocinergic pathway gene ARNT22018Inngår i: Social Cognitive & Affective Neuroscience, ISSN 1749-5016, E-ISSN 1749-5024, Vol. 13, nr 2, s. 173-181Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The ability to correctly understand the emotional expression of another person is essential for social relationships and appears to be a partly inherited trait. The neuropeptides oxytocin and vasopressin have been shown to influence this ability as well as face processing in humans. Here, recognition of the emotional content of faces and voices, separately and combined, was investigated in 492 subjects, genotyped for 25 single nucleotide polymorphisms (SNPs) in eight genes encoding proteins important for oxytocin and vasopressin neurotransmission. The SNP rs4778599 in the gene encoding aryl hydrocarbon receptor nuclear translocator 2 (ARNT2), a transcription factor that participates in the development of hypothalamic oxytocin and vasopressin neurons, showed an association that survived correction for multiple testing with emotion recognition of audio–visual stimuli in women (n = 309). This study demonstrates evidence for an association that further expands previous findings of oxytocin and vasopressin involvement in emotion recognition.

    Autism spectrum disorders before diagnosis: results from routine developmental surveillance at 18 months2016Inngår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 105, nr 7, s. 823-828Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aim: This study investigated the results from the national, routine 18-month developmental surveillance at Child Healthcare Centres (CHCs) on children later diagnosed with autism spectrum disorder (ASD). Methods: Child Healthcare Centre records of 175 children, diagnosed with ASD before 4.5 years in Stockholm County, Sweden, were reviewed regarding the results of the eight-item neurodevelopmental surveillance. Results were contrasted with normative data from the general child population in Stockholm County. Results: More than one-third of the total ASD group, including half of the group with ASD and intellectual disability (ID), did not pass the required number of items, compared to one in 50 in the general child population. Of those with ASD and ID who had passed, more than one-third experienced developmental regression after 18 months of age. If the CHC surveillance had considered reported regulatory problems - crying, feeding and sleeping - then another 10% of the children with ASD and ID could have been identified during this surveillance. Conclusion: The existing CHC surveillance traced half of the group of children who were later diagnosed with ASD combined with intellectual disability. Adding an item on regulatory problems to the 18-month surveillance would have increased this number by another 10%.

    What moderates the accuracy of ease of learning judgments?2017Inngår i: Metacognition and Learning, ISSN 1556-1623, E-ISSN 1556-1631, Vol. 12, nr 3, s. 337-355Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    When people begin to study new material, they may first judge how difficult it will be to learn. Surprisingly, these ease of learning (EOL) judgments have received little attention by metacognitive researchers so far. The aim of this study was to systematically investigate how well EOL judgments can predict actual learning, and what factors may moderate their relative accuracy. In three experiments, undergraduate psychology students made EOL judgments on, then studied, and were tested on, lists of word-pairs (e.g., sun – warm). In Experiment 1, the Goodman-Kruskal gamma (G) correlations showed that EOL judgments were accurate (G = .74) when items varied enough in difficulty to allow for proper discrimination between them, but were less accurate (G = .21) when variation was smaller. Furthermore, in Experiment 1 and 3, we showed that the relative accuracy was reliably higher when the EOL judgments were correlated with a binary criterion (i.e., if an item was recalled or not on a test), compared with a trials-to-learn criterion (i.e., how many study and test trials were needed to recall an item). In addition, Experiments 2 and 3 indicate other factors to be non-influential for EOL accuracy, such as the task used to measure the EOL judgments, and whether items were judged sequentially (i.e., one item at a time in isolation from the other items) or simultaneously (i.e., each item was judged while having access to all other items). To conclude, EOL judgments can be highly accurate (G = .74) and may thus be of strategic importance for learning. Further avenues for research are discussed.

    Social memory associated with estrogen receptor polymorphisms in women2016Inngår i: Social Cognitive & Affective Neuroscience, ISSN 1749-5016, E-ISSN 1749-5024, Vol. 11, nr 6, s. 877-883Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The ability to recognize the identity of faces and voices is essential for social relationships. Although the heritability of social memory is high, knowledge about the contributing genes is sparse. Since sex differences and rodent studies support an influence of estrogens and androgens on social memory, polymorphisms in the estrogen and androgen receptor genes (ESR1, ESR2, AR) are candidates for this trait. Recognition of faces and vocal sounds, separately and combined, was investigated in 490 subjects, genotyped for 10 single nucleotide polymorphisms (SNPs) in ESR1, four in ESR2 and one in the AR. Four of the associations survived correction for multiple testing: women carrying rare alleles of the three ESR2 SNPs, rs928554, rs1271572 and rs1256030, in linkage disequilibrium with each other, displayed superior face recognition compared with non-carriers. Furthermore, the uncommon genotype of the ESR1 SNP rs2504063 was associated with better recognition of identity through vocal sounds, also specifically in women. This study demonstrates evidence for associations in women between face recognition and variation in ESR2, and recognition of identity through vocal sounds and variation in ESR1. These results suggest that estrogen receptors may regulate social memory function in humans, in line with what has previously been established in mice.

    Putting action memory to the test: Testing affects subsequent restudy but not long-term forgetting of action events2016Inngår i: Journal of Cognitive Psychology, ISSN 2044-5911, E-ISSN 2044-592X, Vol. 28, nr 2, s. 209-219Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Testing memory typically enhances subsequent re-encoding of information (“indirect” testing effect) and, as compared to restudy, it also benefits later long-term retention (“direct” testing effect). We investigated the effect of testing on subsequent restudy and 1-week retention of action events (e.g. “water the plant”). In addition, we investigated if the type of recall practice (noun-cued vs. verb-cued) moderates these testing benefits. The results showed an indirect testing effect that increased following noun-cued recall of verbs as compared to verb-cued recall of nouns. In contrast, a direct testing effect on the forgetting rate of performed actions was not reliably observed, neither for noun- nor verb-cued recall. Thus, to the extent that this study successfully dissociated direct and indirect testing-based enhancements, they seem to be differentially effective for performed actions, and may rely on partially different mechanisms.

    Multiple deadlines in metric space: Multitasking reflects selectively coordinate, but not categorical, spatial processing2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    We often need to monitor and coordinate multiple deadlines. One way to handle these temporal demands might be to represent future deadlines as a pattern of spatial relations. More specifically, we tested the hypothesis that multitasking reflects selective effects of coordinate (i.e., metric) relational processing. Participants completed two multitasking sessions under concurrent processing demands of coordinate versus categorical spatial information. We expected and observed that multitasking impairs concurrent coordinate, rather than categorical, spatial processing. In Experiment 1, coordinate-task performance was selectively decreased, while multitasking performance was equal under both load conditions. When emphasizing equal (primary/secondary) task-importance in Experiment 2, it was only multitasking performance that was selectively reduced under the coordinate-load condition. Thus, effective multitasking may partly reflect coordinate-relational processing.

    Loss of Olfactory Function Predicts Mortality Irrespective of Dementia Conversion: 10-year follow-up of an age-varied sample2016Inngår i: Chemical Senses, ISSN 0379-864X, E-ISSN 1464-3553, Vol. 41, nr 9, s. e111-e288Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The objective of this study was to examine the association between performance in odor identification and future mortality in a community cohort of adults aged between 40 and 90 years. We assessed olfactory performance with a 13-item-version of the Scandinavian Odor Identification Test (SOIT). The results showed that during follow-up (mean=9.4 years, standard deviation=2.23), 411 of 1774 (23.2%) participants died. In a Cox model, the association between higher SOIT score and mortality was highly significant (hazard ratio [HR]=0.74, per point interval, 95% confidence interval [CI]=0.71–0.77, p<0.001). The effect was attenuated, but remained significant after controlling for age, sex, education, and health and cognitive variables that were also associated with an increased risk of mortality (HR=0.92, 95% CI=0.87–0.97, p=0.001). Controlling for dementia conversion prior to death did not attenuate the association between SOIT score and mortality (HR=0.92, 95% CI=0.87–0.97, p=0.001). Similar results were obtained for olfactory sensitivity as assessed by self-report. Overall, the present findings show that poor odor identification performance is associated with an increased likelihood of future mortality in middle-aged and older adults, after controlling for social, cognitive, and medical risk factors. Most importantly, controlling for the development of dementia did not attenuate the association between odor identification and mortality, suggesting that olfactory decline might mark deteriorating health also irrespective of dementia.

    Olfactory LOVER: behavioral and neural correlates of autobiographical odor memory2014Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 5, artikkel-id 312Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Autobiographical memories (AMs) are personally experienced events that may be localized in time and space. In the present work we present an overview targeting memories evoked by the sense of smell. Overall, research indicates that autobiographical odor memory is different than memories evoked by our primary sensory systems; sight, and hearing. Here, observed differences from a behavioral and neuroanatomical perspective are presented. The key features of an olfactory evoked AM may be referred to the LOVER acronym-Limbic, Old, Vivid, Emotional, and Rare.

    Bad odors stick better than good ones: Olfactory qualities and odor recognition2009Inngår i: Experimental psychology (Göttingen), ISSN 1618-3169, E-ISSN 2190-5142, Vol. 56, nr 6, s. 375-380Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The influences of perceived odor qualities on the retention of olfactory information across the adult lifespan were examined. Young (19–36 years), young-old (60–74 years), and old (75–91 years) adults (n = 202) rated a set of unfamiliar odors across a series of perceptual dimensions (i.e., pleasantness, intensity, and irritability) at encoding. The overall results indicated that memory for unpleasant olfactory information was better than that for pleasant odors across the lifespan. Also, participants showed better retention for odors perceived with high intensity and irritability than for odors rated with low or medium scores. Interestingly, the old adults showed selective beneficial memory effects for odors rated as highly irritable. To the extent that perceptions of high irritability reflect an activation of the trigeminal sensory system, this finding suggests that older adults may use trigeminal components in odor information to compensate for age-related impairments in olfactory memory.

    Assessing Boundary Conditions of the Testing Effect: On the Relative Efficacy of Covert vs. Overt Retrieval2017Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 8, artikkel-id 1018Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Repeated testing during learning often improves later memory, which is often referred to as the testing effect. To clarify its boundary conditions, we examined whether the testing effect was selectively affected by covert (retrieved but not articulated) or overt (retrieved and articulated) response format. In Experiments 1 and 2, we compared immediate (5 min) and delayed (1 week) cued recall for paired associates following study-only, covert, and overt conditions, including two types of overt articulation (typing and writing). A clear testing effect was observed in both experiments, but with no selective effects of response format. In Experiments 3 and 4, we compared covert and overt retrieval under blocked and random list orders. The effect sizes were small in both experiments, but there was a significant effect of response format, with overt retrieval showing better final recall performance than covert retrieval. There were no significant effects of blocked versus random list orders with respect to the testing effect produced. Taken together, these findings suggest that, under specific circumstances, overt retrieval may lead to a greater testing effect than that of covert retrieval, but because of small effect sizes, it appears that the testing effect is mainly the result of retrieval processes and that articulation has fairly little to add to its magnitude in a paired-associates learning paradigm.

    The expression and recognition of emotions in the voice across five nations: A lens model analysis based on acoustic features2016Inngår i: Journal of Personality and Social Psychology, ISSN 0022-3514, E-ISSN 1939-1315, Vol. 111, nr 5, s. 686-705Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study extends previous work on emotion communication across cultures with a large-scale investigation of the physical expression cues in vocal tone. In doing so, it provides the first direct test of a key proposition of dialect theory, namely that greater accuracy of detecting emotions from one’s own cultural group—known as in-group advantage—results from a match between culturally specific schemas in emotional expression style and culturally specific schemas in emotion recognition. Study 1 used stimuli from 100 professional actors from five English-speaking nations vocally conveying 11 emotional states (anger, contempt, fear, happiness, interest, lust, neutral, pride, relief, sadness, and shame) using standard-content sentences. Detailed acoustic analyses showed many similarities across groups, and yet also systematic group differences. This provides evidence for cultural accents in expressive style at the level of acoustic cues. In Study 2, listeners evaluated these expressions in a 5 × 5 design balanced across groups. Cross-cultural accuracy was greater than expected by chance. However, there was also in-group advantage, which varied across emotions. A lens model analysis of fundamental acoustic properties examined patterns in emotional expression and perception within and across groups. Acoustic cues were used relatively similarly across groups both to produce and judge emotions, and yet there were also subtle cultural differences. Speakers appear to have a culturally nuanced schema for enacting vocal tones via acoustic cues, and perceivers have a culturally nuanced schema in judging them. Consistent with dialect theory’s prediction, in-group judgments showed a greater match between these schemas used for emotional expression and perception.

    Choice-Supportive Misremembering: A New Taxonomy and Review2017Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 8, artikkel-id 2062Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Although the literature on the influence of memory on decisions is well developed, research on the effects of decision making on memory is rather sparse and scattered. Choice-supportive misremembering (i.e., misremembering choice-related information that boosts the chosen option and/or demotes the foregone options) has been observed in several studies and has the potential to affect future choices. Nonetheless, no attempt has been made to review the relevant literature, categorize the different types of choice-supportive misremembering observed, and critically appraise the existing evidence and proposed explanations. Thus, starting from a new theoretically motivated and empirically grounded taxonomy, we review the current research. Our taxonomy classifies choice-supportive misremembering into four conceptually distinct types: misattribution is when information is attributed to the wrong source, fact distortion when the facts are remembered in a distorted manner, false memory when items that were not part of the original decision scenarios are remembered as presented and, finally, selective forgetting is when information is selectively forgotten. After assessing the impact of various potentially moderating factors, we evaluate the evidence for each type of misremembering and conclude that the support for the phenomenon is solid in relation to misattribution when recognition memory is assessed, but significantly weaker for the other three types, and when other memory tests are used to assess memory. Finally, we review the cognitive and emotional explanations proposed for choice-supportive misremembering in the light of the available evidence and identify the main gaps in the current knowledge and the more promising avenues for future research.

    Predictive accuracy of Wechsler Adult Intelligence Scale, forth ed., (WAIS-IV) seven- and four- subtest short form models in estimating full scale IQ (FSIQ) and its indices in a Swedish non-clinical sample2016Inngår i: Proceedings of 4th Global Experts Meeting on Neuropharmacology, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Neurodegenerative disorders usually show characteristic cognitive profiles, determined by the anatomical dispersion of neuronal loss. Short-term/memory decline is a presenting symptom on Alzheimer’s disease, but atypical early signs also occur. The Wechlser Adult Intelligence Scale (WAIS) may be used to differentiate between normal and sub-normal cognitive performance levels, such as pre-dementia stages, AD and related disorders. According to Meyers et al., (2013), a brief measure consisting of a seven-subtest short form (SF) of the WAIS-IV including Block Design (BD), Similarities (SI), Digit Span (DS), Arithmetic (AR), Information (IN) Coding (CD) and Picture Completion (PC) provides a valid means of measuring cognitive level. In order to validate a short form of WAIS-IV on a Swedish non-clinical sample the aim of the present study was to assess the ability of the seven-subtest SF as well as a reduction of the number of subtests in the SF based on standardized β-values, to predict the full scale IQ (FSIQ) and its indices. WAIS-IV scaled score data from 98 healthy individuals (19-90 years M=46 years, SD=23 years, females=48, males=50) were analyzed with linear regression, which showed that the seven predictors explained 92.5% of the variance in FSIQ. When reducing the SF-set the four highest β-values were obtained from the following subtests: CD, β=0.34 (Processing Speed), SI, β=0.31 (Verbal Comprehension), BD, β=0.25 (Perceptual Reasoning), and AR, β=0.23 (Working memory), which showed to be one subtest from each of the four indices. FSIQ prediction rate of these four subtests was 88.1%. Each of the four subtests correlated significantly on p=<0.01 level with its index. To conclude, FSIQ prediction accuracy for the seven-subtest SF is very high, as well as for the four-subtest model. Since the four-subtest model strongly predicts FSIQ, as well as all its indices, it may be a valid, and timesaving, instrument to assess short-term memory (AR, partly CD) deficits typical for different stages of AD, signs on non-amnestic decline in AD, as well as typical clinical manifestations of frontotemporal degeneration, Parkinson’s disease, Lewy body disease, ischemic brain disorders and cognitive dysfunctions associated with depression. In unclear cases additional testing is necessary. Further analyses will reveal possible influences on the norms of age, genus and education.

    Social influences on dissonance reduction in medical decision making2016Inngår i: Book of abstracts, 2016, s. 28-28Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Two studies investigated social influences on dissonance reduction in medical decision making. Study 1 compared decision-consistent biases when individuals freely made-, or when another person made the decision. Participants read a scenario in which one of two patients should be prioritized for surgery. Facts about the patients were given on counter-balanced scales. Participants decided themselves whom to prioritize, or were told that a physician made the decision, and then reproduced the facts from memory. When choosing freely, participants distorted memories of facts to become more supportive of the choice. This effect was evident, albeit reduced, when the decision was made by a physician.

    Study 2 investigated majority/minority feedback effects on dissonance reduction for decisions concerning ingroup or outgroup members. Swedish participants decided whether a physician should comply or not to the request of a terminally ill patient, with a Swedish or a Turkish name, who asked for help to commit suicide. After making their decision, participants were informed that a majority or a minority had chosen the same alternative. Decisions about an in-group member were consolidated more if participants received minority, than majority feedback. This reversed for decisions on out-group member. Results suggest important social moderators of dissonance reduction strategies.

    The effect of language skills on dementia in a Swedish longitudinal cohort2016Inngår i: Linguistic Approaches to Bilingualism, ISSN 1879-9264, E-ISSN 1879-9272, Vol. 6, nr 1-2, s. 190-204Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recent findings indicate that bilingualism delay the onset of dementia. Using data from the Betula longitudinal cohort study on memory, health and aging (www.betula.su.se) the issue of a possible protective effect of bilingualism was addressed. Monolingual (n = 736) and bilingual (n = 82) participants (= 60 years) without dementia at inclusion were followed for incident dementia over a time-period up to 10 years. In total, 112 participants developed dementia. Analyses were performed with Cox proportional hazards regression adjusted for age, sex, and presence/absence of the Apolipoprotein E (APOE) epsilon 4 allele, with dementia outcome as the dependent variable. Results showed no delayed onset of dementia in bilinguals compared to monolinguals. However, because of the findings from a study using participants from the same population showing beneficial longitudinal effects of bilingualism on episodic memory; we argue that our results may depend on the frequency of use of the second language after retirement.

    What people believe about memory.2006Inngår i: Memory, ISSN 0965-8211, Vol. 14, nr 5, s. 595-613Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Two representative samples of adult Norwegians (n = 2000) were asked a set of general and specific questions regarding their beliefs and opinions about human memory. The results indicate that on many questions, such as time of the earliest memories, inhibiting effects of collaboration, and memory for dramatic versus ordinary events, the views of the general public concurred with current research findings, and people in general had realistic views about their own memory performance. On other questions, such as the reliability of olfactory as compared with visual and auditory memory, the memory of small children in comparison with that of adults, the likelihood of repression of adult traumatic memories, and on more general questions such as the possibility of training memory and the capacity limitations of long-term memory, a large proportion of the participants expressed views that are less supported by scientific evidence. Implications of these findings are briefly discussed.

    Time takes space: selective effects of multitasking on concurrent spatial processing2017Inngår i: Cognitive Processing, ISSN 1612-4782, E-ISSN 1612-4790, Vol. 18, nr 3, s. 229-235Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Many everyday activities require coordination and monitoring of complex relations of future goals and deadlines. Cognitive offloading may provide an efficient strategy for reducing control demands by representing future goals and deadlines as a pattern of spatial relations. We tested the hypothesis that multiple-task monitoring involves time-to-space transformational processes, and that these spatial effects are selective with greater demands on coordinate (metric) than categorical (nonmetric) spatial relation processing. Participants completed a multitasking session in which they monitored four series of deadlines, running on different time scales, while making concurrent coordinate or categorical spatial judgments. We expected and found that multitasking taxes concurrent coordinate, but not categorical, spatial processing. Furthermore, males showed a better multitasking performance than females. These findings provide novel experimental evidence for the hypothesis that efficient multitasking involves metric relational processing.

    Deadlines in Space: Selective Effects of Coordinate Spatial Processing in Multitasking2016Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Many everyday activities require coordination and monitoring of multiple deadlines. One way to handle these temporal demands might be to represent future goals and deadlines as a pattern of spatial relations. We examined the hypothesis that spatial ability, in addition to executive functioning, contributes to individual differences in multitasking. Participants completed a multitasking session in which they monitored four digital clocks running at different rates. We predicted and found that individual differences in spatial ability and executive functions were independent predictors of multiple-task performance. Individual differences in spatial ability were also selectively related to multiple-task performance, as only coordinate spatial processing, but not categorical, predicted multitasking, even beyond executive functioning and numeracy. Furthermore, males outperformed females in spatial ability and multitasking and these sex differences generalized to a complex simulation of everyday multitasking. Menstrual changes moderated these effects in that sex differences in coordinate spatial processing and multitasking were observed between males and females in the luteal phase of the menstrual cycle, but not between males and females at menses. Overall, these findings suggest that multiple task performance reflects independent contributions of spatial ability and executive functioning. Furthermore, our results support the distinction of categorical vs. coordinate spatial processing, and suggest that these two basic relational processes are selectively affected by female sex hormones and differentially effective in transforming and handling temporal patterns as spatial relations in the context of multitasking.

    Emotion appraisal dimensions inferred from vocal expressions are consistent across cultures: a comparison between Australia and India2017Inngår i: Royal Society Open Science, E-ISSN 2054-5703, Vol. 4, nr 11, artikkel-id 170912Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study explored the perception of emotion appraisal dimensions on the basis of speech prosody in a cross-cultural setting. Professional actors from Australia and India vocally portrayed different emotions (anger, fear, happiness, pride, relief, sadness, serenity and shame) by enacting emotion-eliciting situations. In a balanced design, participants from Australia and India then inferred aspects of the emotion-eliciting situation from the vocal expressions, described in terms of appraisal dimensions (novelty, intrinsic pleasantness, goal conduciveness, urgency, power and norm compatibility). Bayesian analyses showed that the perceived appraisal profiles for the vocally expressed emotions were generally consistent with predictions based on appraisal theories. Few group differences emerged, which suggests that the perceived appraisal profiles are largely universal. However, some differences between Australian and Indian participants were also evident, mainly for ratings of norm compatibility. The appraisal ratings were further correlated with a variety of acoustic measures in exploratory analyses, and inspection of the acoustic profiles suggested similarity across groups. In summary, results showed that listeners may infer several aspects of emotion-eliciting situations from the non-verbal aspects of a speaker's voice. These appraisal inferences also seem to be relatively independent of the cultural background of the listener and the speaker.

    Learning to recognize younger faces at an older age2017Inngår i: Aging Clinical and Experimental Research, ISSN 1594-0667, E-ISSN 1720-8319, Vol. 29, nr 2, s. 191-196Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: Processing of horizontal face cues has been shown to be an important element in face recognition of adults aged up to 30 years. In contrast, horizontally aligned facial features do not appear to contribute to older adults’ (60–75 years) recognition in a similar way. To this end, we investigated potential learning effects on the ability to recognize faces based on horizontal features. Previous research suggests face recognition based on all face information experiences an accelerated decline after the age of 70. However, recognition based only on horizontal face information has not yet been studied in old age (75+ years of age). Thus, we investigated whether older adults (aged up to as well as starting at 75 years) can learn to recognize faces based on horizontal face cues alone.

    Method: One younger and two older adult groups (20–30, 60–75, and 75+ years) were familiarized with a high and a low amount of previously unfamiliar faces—some containing all face cues and others containing only horizontal face cues (reduced information). Subsequently, all groups received a recognition test.

    Results: Repeated learning increased natural face recognition for all three age groups when all face cues were available. However, increases in face recognition were only observed for younger adults when horizontal face cued were only available.

    Discussion: The importance of horizontally aligned spatial frequencies for recognizing human faces is lessened before the age of 60 (and plateaus thereon), whereas recognition of stimuli containing all face cues is still capable of improvement.

    Long-term episodic memory decline is associated with olfactory deficits only in carriers of ApoE-є42016Inngår i: Neuropsychologia, ISSN 0028-3932, E-ISSN 1873-3514, Vol. 85, s. 1-9Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The ɛ4 allele of the Apolipoprotein E gene is a genetic risk factor for late-onset dementia of the Alzheimers' type (DAT), which is characterized by loss of both episodic memoryand olfactory functions. Little is known about the possible role of ɛ4 in the association between ongoing episodic memory decline and olfactory deficits in the general population, but such information is relevant in determining the relevance of olfaction as a marker of DAT risk. The present study was based on a large, population-based sample (n=1087, aged 45–90 years, of which 324 were ɛ4-carriers). Episodic memory change rates were established using data collected every 5 years for a 10–20 year interval leading up to an olfactory assessment using the Scandinavian Odor Identification Test at the last wave of data collection. Participants were classified according to whether or not their episodic memory ability declined more rapidly than the age-typical norm (by >1SD). Our main result is that only in ɛ4-carriers was episodic memory decline associated with odor identification impairment. In individuals without ɛ4, odor identification was unrelated to episodic memory decline status. Follow-up analyses indicated that this moderation by ɛ4 was due to the olfactory nature of the identification test, and that the effect was not caused by 63 individuals with dementia. Our results suggest that the ɛ4 determines the functional association between ongoing episodic memory decline and olfaction. These findings are consistent with the notion that ɛ4-carriers with DAT, compared to non-carriers, display a cortical atrophy pattern that is more focused on mediotemporal lobe regions supporting olfactory and episodic memory functions. Olfactory and memory assessments might provide complementary information on mediotemporal atrophy prior to clinical dementia onset, but the ɛ4 should be considered when using olfactory assessment as an early-stage indicator.
