Background: There are concerns and diverse experiences related to infertility and childlessness. The lived experience of infertile people from various cultures needs to be explored. Objective: The aim of this qualitative study was to explore Iranian women experiences of their infertility. Materials and Methods: The data comprised interviews about fertility issues in the Persian language with eighteen women, aged 17-45 yr old, who agreed to be interviewed at the Mottahari Infertility Treatment Clinic, affiliated to the Urmia University of Medical Sciences about their fertility problems. They were approached by the researchers at the time of their first visit. The verbatim transcribed interviews were analyzed using deductive conventional content analysis. Results: The experiences of the informants were conceptualized into four major themes: 1) Shock (subthemes: Disbelief and Denial); 2) Reaction (subthemes: Distress, Guilt, Loss of self-esteem and Sexual reluctance); 3) Processing (subthemes: Internal processing, Avoidance, Marriage at risk, External processing, Stigma caused by the family and Stigma caused by the community) and 4) Reorientation (subthemes: Forgetting, Marriage to saving marriage and Sexual consent). Conclusion: Infertility can be a challenging condition. Considering that infertility-related issues affect Iranian women more contextual factors is necessary. So, culturally sensitive and gender specific protocols are suggested to provide suitable and about culturally sensitive and gender-specific protocols is a necessity in order to provide suitable care to infertile women.

Aims: Employee-based flexible working hours are increasing, particularly among knowledge workers. Research indicates that women and men use work–time control (WTC; control over time off and daily hours) differently: while men work longer paid hours, women use WTC to counteract work–life interference. In a knowledge-worker sample, we examined associations between WTC and overtime, work–life interference and exhaustion and tested whether gender moderates the mediating role of overtime. Methods: The sample contained 2248 Swedish knowledge workers. Employing hierarchical regression modelling, we examined effects of control over time off/daily hours on subsequent overtime hours, work–life interference and exhaustion in general and in gender-stratified samples. Using conditional process analysis, we tested moderated mediation models. Results: Control over time off was related to less work–life interference (β_men= −0.117; 95% confidence interval (CI): −0.237 to 0.003; β_women= −0.253; 95% CI: −0.386 to −0.120) and lower exhaustion (β_men= −0.199; 95% CI: −0.347 to −0.051; β_women= −0.271; 95% CI: −0.443 to −0.100). For control over daily hours, estimates were close to zero. While men worked more overtime (42 min/week), we could not confirm gender moderating the indirect effect of control over time off/daily hours on work–life interference/exhaustion via overtime. Independent of gender, effects of control over time off on work–life interference were partly explained by working fewer overtime hours. Conclusions: Control over time off was related to lower exhaustion and better work–life balance (in particular for women). We found no evidence for men’s work–life interference increasing with higher WTC owing to working more overtime. Knowledge workers’ control over time off may help prevent work–life interference and burnout.

Background: The effect of regional brain amyloid-beta (A beta) pathology on specific cognitive functions is incompletely known.

Objective: The relationship between A beta and cognitive functions was investigated in this cross-sectional multicenter study of memory clinic patients.

Methods: The participants were patients diagnosed with Alzheimer's disease (AD, n = 83), mild cognitive impairment (MCI, n = 60), and healthy controls (HC, n = 32), who had been scanned by C-11-PiB PET in 13 brain regions of both hemispheres and who had been assessed by cognitive tests covering seven domains.

Results: Hierarchic multiple regression analyses were performed on each cognitive test as dependent variable, controlling for demographic characteristics and APOE status (block 1) and PiB measures in 13 brain regions (block 2) as independent variables. The model was highly significant for each cognitive test and most strongly for tests of episodic memory (learning and retention) versus PiB in putamen, visuospatially demanding tests (processing and retention) versus the occipital lobe, semantic fluency versus the parietal lobe, attention versus posterior gyrus cinguli, and executive function versus nucleus accumbens. In addition, education had a positively and APOE status a negatively significant effect on cognitive tests.

Conclusion: Five subcortical and cortical regions with A beta pathology are differentially associated with cognitive functions and stages of disease in memory clinic patients.

Practice effects (PEs) defined as an improvement of performance in cognition due to repeated assessments between sessions are well known in unimpaired individuals, while less is known about impaired cognition and particularly in latent brain disease as autosomal-dominant Alzheimer's disease. The purpose was to evaluate the general (across tests/domains) and domain-specific PE calculated as the annual rate of change (ARC) in relation to years to the estimated disease onset (YECO) and in four groups of AD: asymptomatic mutation carriers (aAD, n = 19), prodromal, i.e., symptomatic mutation carriers, criteria for AD diagnosis not fulfilled (pAD, n = 4) and mutation carriers diagnosed with AD (dAD, n = 6) as well as mutation non-carriers from the AD families serving as a healthy comparison group (HC, n = 35). Cognition was assessed at baseline and follow-up about 3 years later by 12 tests covering six domains. The aAD and HC groups were comparable at baseline in demographic characteristics (age, gender, and education), when they were in their early forties, while the pAD and dAD groups were older and cognitively impaired. The results on mean ARC for the four groups were significantly different, small, positive, and age-insensitive in the HC group, while ARC was negative and declined with time/disease advancement in AD. The differences between HC and aAD groups in mean ARC and domain-specific ARC were not significant, indicating a subtle PE in aAD in the early preclinical stage of AD. In the symptomatic stages of AD, there was no PE probably due to cognitive disease-related progression. PEs were the largest in the verbal domain in both the HC and aAD groups, indicating a relationship with cognitive vulnerability. The group-related difference in mean ARC was predominant in timekeeping tests. To conclude, the practice effect in over 3 years was suggested to be linked to procedural learning and memory.

Mounting evidence shows that the APOE ε4 allele interferes with cognition in sporadic Alzheimer’s disease. Less is known about APOE in autosomal-dominant Alzheimer’s disease (adAD). The present study explored the effects on cognition associated with the gene–gene interactions between the APOE gene and the APP and PSEN1 genes in adAD. This study includes mutation carriers (MC) and non-carriers (NC) from adAD families with mutations in APP (n = 28 and n = 25; MC and NC, respectively) and PSEN1 (n = 12 and n = 15; MC and NC, respectively) that represent the complete spectrum of disease: AD dementia (n = 8) and mild cognitive impairment (MCI, n = 15 and presymptomatic AD, n = 17). NC represented unimpaired normal aging. There was no significant difference in the distribution of APOE ε4 (absence vs. presence) between the APP vs. PSEN1 adAD genes and mutation status (MC vs. NC). However, episodic memory was significantly affected by the interaction between APOE and the APP vs. PSEN1 genes in MC. This was explained by favorable performance in the absence of APOE ε4 in PSEN1 compared to APP MC. Similar trends were seen in other cognitive functions. No significant associations between APOE ε4 and cognitive performance were obtained in NC. In conclusion, cognitive effects of APOE–adAD gene interaction were differentiated between the PSEN1 and APP mutation carriers, indicating epistasis.

BackgroundIt is possible to calculate the number of years to the expected clinical onset (YECO) of autosomal-dominant Alzheimer's disease (adAD). A similar time scale is lacking for sporadic Alzheimer's disease (sAD). The purpose was to design and validate a time scale in YECO for patients with sAD in relation to CSF and PET biomarkers.MethodsPatients diagnosed with Alzheimer's disease (AD, n = 48) or mild cognitive impairment (MCI, n = 46) participated in the study. They underwent a standardized clinical examination at the Memory clinic, Karolinska University Hospital, Stockholm, Sweden, which included present and previous medical history, laboratory screening, cognitive assessment, CSF biomarkers (A beta(42), total-tau, and p-tau), and an MRI of the brain. They were also assessed with two PET tracers, C-11-Pittsburgh compound B and F-18-fluorodeoxyglucose. Assuming concordance of cognitive decline in sAD and adAD, YECO for these patients was calculated using equations for the relationship between cognitive performance, YECO, and years of education in adAD (Almkvist et al. J Int Neuropsychol Soc 23:195-203, 2017).ResultsThe mean current point of disease progression was 3.2 years after the estimated clinical onset in patients with sAD and 3.4 years prior to the estimated clinical onset in patients with MCI, as indicated by the median YECO from five cognitive tests. The associations between YECO and biomarkers were significant, while those between chronological age and biomarkers were nonsignificant. The estimated disease onset (chronological age minus YECO) followed a bimodal distribution with frequency maxima before (early-onset) and after (late-onset) 65 years of age. The early- and late-onset subgroups differed significantly in biomarkers and cognition, but after control for YECO, this difference disappeared for all except the APOE e4 gene (more frequent in early- than in late-onset).ConclusionsA novel time scale in years of disease progression based on cognition was designed and validated in patients with AD using CSF and PET biomarkers. Two early- and late-disease onset subgroups were identified differing with respect to APOE e4.

Objective: Benevolence is an emerging concept in motivation theory and research as well as in on pro-social behavior, which has stimulated increasing interest in studying factors that impair or facilitate benevolence and effects thereof. This exploratory study examines the associations between benevolence, stress, mental health, self-compassion, and satisfaction with life in two workplace samples.

Methods: In the first study n = 522 (38% = female, median age = 42) participants answered questionnaires regarding self-reported stress symptoms (i.e., emotional exhaustion), depressive symptoms and benevolence. In the second study n = 49 (female = 96%) participants answered questionnaires regarding perceived stress, self-compassion, anxiety, depression symptoms, and benevolence.

Results: In study 1, measures of emotional exhaustion (r = −0.295) and depression (r = −0.190) were significantly negatively correlated with benevolence. In study 2, benevolence was significantly negatively correlated with stress (r = −0.392) and depression (r = −0.310), whereas self-compassion (0.401) was significantly positively correlated with benevolence. While correlations were in expected directions, benevolence was not significantly associated with Satisfaction with Life (r = 0.148) or anxiety (r = −0.199) in study 2.

Conclusion: Self-assessed benevolence is associated with levels of perceived stress, exhaustion, depression, and self-compassion. Future studies are warranted on how benevolence is related to stress and mental ill health such as depression and anxiety, and if benevolence can be trained in order to decrease stress and mental ill health such as depression and anxiety in workplace settings.

Under covid-19-pandemins första våg, tidigt våren 2020, valde de flesta länder, inklusive Sverige, att rekommendera eller kräva att de anställda som kunde skulle arbeta på distans från bostaden för att minska smittspridningen på arbetsplatser och under resor till och från dessa arbetsplatser. Att arbeta på distans skiljer sig i många avseenden från att arbeta i arbetsgivarens lokaler.

Det övergripande syftet med denna översikt, som består av tre delar, har varit att sammanställa och öka den forskningsbaserade kunskapen om distansarbete i hemmet.

Översikten omfattar forskningslitteratur inom tre områden:

• arbetsmiljö och hälsa
• balans mellan arbetsliv och privatliv
• produktivitet.

I analyserna har vi därtill särskilt fokuserat på likheter och skillnader i mäns och kvinnors villkor vid lönearbete i hemmet. Ytterligare syften har varit att undersöka och dra slutsatser om distansarbete i hemmet under tiden före respektive under pandemin.

When participating in dialogue, speakers design their utterances to accommodate the individual needs of listeners (Bentz, et al., in prep). This feature is known as audience design (Clark & Murphy, 1982). Although audience design is central to conventional conversation, it is not known at which age speakers begin taking into account the world knowledge/frame of reference of their interlocutors. Indications from recent studies suggest that albeit preschool and first grade children engage in basic forms of perspective taking (Nadig & Sedivy, 2002), they fail to adapt their utterances in accordance with listener-specific needs in reference production (Pagmar, et al., in prep). Adult participants do however adapt their utterances, and individual differences in the adult population were not dependent on cognitive control function (Bentz, et al., in prep). The dependence on cognitive control function, e.g. switching, may be hypothesized to be greater in children. The current study aims to test the referential production of two age groups; early and mid adolescents (11;0-12;11 and 15;0-16;11), with the purpose of tracing the development of the ability to use information regarding listener-perspective during on-line referential production, and test its relation to cognitive control. The paradigm builds further on the well-established Director’s task but does not require the participants to take the visual perspective of the listener. Instead, participants are presented with a set of pictures portraying referents well-known to them, e.g. popular cartoon characters, hosts of children’s tv-shows, etc. Knowledge of the referents are controlled through post-test surveys. Furthermore, they are asked to direct listeners of two distinct groups, small children and elders, into choosing the target referent. Participants who take the frame of reference of addressees into consideration are expected to adopt different strategies when addressing the different groups, i.e., increase informativeness when denoting referents assumed to be unknown to the listener vs using less informative referential expressions (such as proper names) when denoting referents judged to be known to the listener. Cognitive control/executive function is assessed using the Wisconsin card sorting task. Results are discussed in terms of cognitive costs of switching strategies and the Gricean maxim of quantity.

The ability to adapt utterances to the world knowledge of one’s addressee is undeniably ubiquitous in human social cognition, but its development and association with other cognitive mechanisms during adolescence have not been studied. In an online production task, we measured the ability of children entering adolescence (ages 11–12, M= 11.8, 𝑁=29,17girlsN=29, 17 girls) and adolescents (ages 15–16, M = 15.9, 𝑁=29,17girlsN=29, 17 girls) to tailor referential expressions in accordance with the inferred world knowledge of their addressee—an ability we refer to as world knowledge-based audience design (AD). A post-test survey showed that both age groups held similar assumptions about the addressees’ knowledge of referents, but the younger age group did not consistently adapt their utterances in accordance with these assumptions during online production, resulting in a significantly improved AD behaviour across age groups. We also investigated the reliance of AD on executive functions (EF). Executive functioning (as reflected by performance on the Wisconsin card sorting task) increased significantly with age, but did not explain the age-related increase in AD performance. We thus provide evidence in support of an adolescent development of world knowledge-based AD over and above development of EF.

Interest is surging around the ”next-word-predictability” task that allowed large language models to reach their current capacity. It is sometimes claimed that prediction is enough to model language production. We set out to study predictability in an interactive setting. The current fMRI study used the information-theoretic measure of surprisal – the negative log-probability of a word occurring given the preceding linguistic context, estimated by a pre-trained language model (GPT-2). Surprisal has been shown to correlate with bottom-up processing located in the bilateral middle and superior temporal gyri (MTG/STG) during narrative comprehension (Willems et al., 2016). Still, surprisal has never been used to investigate conversational comprehension or any kind of language production. We hypothesized that previous results on surprisal in narrative comprehension would be replicated with conversational comprehension and that next-word- predictability would not encompass language production processes. We utilized a publicly available fMRI dataset in which participants (N=24) engaged in unscripted conversations (12 min/participant) via an audio- video link with a confederate outside the scanner. The conversational events Production, Comprehension, and Silence were modeled in a whole-brain analysis. Two parametric modulations of production and comprehension were added: (1) log-transformed context-independent word frequency (control regressor) and (2) surprisal. Production-surprisal and Comprehension-surprisal were respectively contrasted against the implicit baseline. These contrasts were compared with the contrasts Production and Comprehension vs implicit baseline. If surprisal merely indexed part of the activity in the latter, broader contrasts, this provides a handle on production and comprehension processes beyond next-word-predictability. For surprisal in conversational production, we observed statistically signi�cant clusters in the left inferior frontal gyrus (LIFG), the medial frontal gyrus, and the motor cortex. Importantly, Production vs implicit baseline showed bilateral STG activation while STG was not parametrically modulated by surprisal. Moreover, the bilateral MTG/STG were the only clusters active for Comprehension vs implicit baseline and they were also modulated by surprisal. For comprehension, we thus replicated the previous narrative comprehension study (Willems et al.,2016), showing that unpredictable words activate the bilateral MTG/STG also in conversational settings. Next- word-predictability is thus so far a good model for conversational comprehension. For production, however, the next-word-predictability task helped to hone in on what is sometimes considered core production machinery in LIFG. Several functional interpretations of the STG recruitment during production are possible (such as monitoring for speech errors), but the current results point in the direction of two important conclusions: (1) a functional division of the frontal and temporal cortices during production, where the frontal component is prediction-related, and (2) that language processing during production is more than prediction, at least at the word-level. We provide a functional handle on such extra-predictive processes.

In predictive coding, experience generates predictions that attenuate the feeding forward of predicted stimuli while passing forward unpredicted “errors.” Different models have suggested distinct cortical layers, and rhythms implement predictive coding. We recorded spikes and local field potentials from laminar electrodes in five cortical areas (visual area 4 [V4], lateral intraparietal [LIP], posterior parietal area 7A, frontal eye field [FEF], and prefrontal cortex [PFC]) while monkeys performed a task that modulated visual stimulus predictability. During predictable blocks, there was enhanced alpha (8 to 14 Hz) or beta (15 to 30 Hz) power in all areas during stimulus processing and prestimulus beta (15 to 30 Hz) functional connectivity in deep layers of PFC to the other areas. Unpredictable stimuli were associated with increases in spiking and in gamma-band (40 to 90 Hz) power/connectivity that fed forward up the cortical hierarchy via superficial-layer cortex. Power and spiking modulation by predictability was stimulus specific. Alpha/beta power in LIP, FEF, and PFC inhibited spiking in deep layers of V4. Area 7A uniquely showed increases in high-beta (∼22 to 28 Hz) power/connectivity to unpredictable stimuli. These results motivate a conceptual model, predictive routing. It suggests that predictive coding may be implemented via lower-frequency alpha/beta rhythms that “prepare” pathways processing-predicted inputs by inhibiting feedforward gamma rhythms and associated spiking.

Face-to-face communication requires skills that go beyond core language abilities. In dialogue, we routinely make inferences beyond the literal meaning of utterances and distinguish between different speech acts based on, e.g., contextual cues. It is, however, not known whether such communicative skills potentially overlap with core language skills or other capacities, such as theory of mind (ToM). In this functional magnetic resonance imaging (fMRI) study we investigate these questions by capitalizing on individual variation in pragmatic skills in the general population. Based on behavioral data from 199 participants, we selected participants with higher vs. lower pragmatic skills for the fMRI study (N = 57). In the scanner, participants listened to dialogues including a direct or an indirect target utterance. The paradigm allowed participants at the whole group level to (passively) distinguish indirect from direct speech acts, as evidenced by a robust activity difference between these speech acts in an extended language network including ToM areas. Individual differences in pragmatic skills modulated activation in two additional regions outside the core language regions (one cluster in the left lateral parietal cortex and intraparietal sulcus and one in the precuneus). The behavioral results indicate segregation of pragmatic skill from core language and ToM. In conclusion, contextualized and multimodal communication requires a set of interrelated pragmatic processes that are neurocognitively segregated: (1) from core language and (2) partly from ToM.

Background: Research has demonstrated that cognitive heterogeneity occurs with aging both within and between individuals. The purpose of this study was to explore whether the cognitive heterogeneity in aging was related to the subgroups of successful and usual aging.

Method: Participants were a representative sample of normal older adults (n = 65, age range 70–89 years). All subjects had participated in the third phase of the Nord-Trøndelag Health Survey (HUNT3) and completed all subtests in the Wechsler Memory Scale (WMS-III) and Wechsler Adult Intelligence Scale (WAIS-III). Successful aging was defined in four ways in the study: as (1) absence of disease, (2) high functioning, (3) active engagement with life, or (4) all three components combined. Five domains of memory and intelligence functions were investigated using linear regression analysis, with group membership (successful versus usual aging) as predictors and age, sex and education as correlates.

Results: Processing speed performance was correlated with the successful aging component absence of disease, younger age and being of the female sex, while working memory performance was correlated with the successful aging component absence of disease and more years of education. Performance in other domains (verbal, visuospatial, and episodic memory) were not related to any successful aging definition. Age had a consistent negative effect on the processing speed domain for all successful aging definitions. Education was positively linked to cognitive performance on the verbal and working memory domains. Being female was positively linked to processing speed and episodic memory.

Conclusions: Processing speed and working memory were linked to successful aging when it was defined as absence of disease, but not by other components of successful aging, i.e. domain-specific. In contrast, other cognitive domains were not related to any components of successful aging.
