    Assessing the significance of Tallal's transform2002Inngår i: TMH-QPSR 44: Proceedings Fonetik 2002, 141-144, Stockholm, Sweden, 2002, s. 141-144Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The perceptual significance of enhancing amplitude contrasts at the onset of formant transitions in CV-syllables and of reducing the “speaking” tempo was studied with a group of normally developing school children. Natural and synthetic speech stimuli were used in the perception experiments. A total of 83 children, second and third graders, were tested on their ability to discriminate between CV syllables presented in pairs. The results indicate that the children’s discrimination performance resisted acoustic manipulations of both the natural and synthetic stimuli. Neither spectral nor timing manipulations rendered significant differencesin discrimination results.

    On Linguistic and Interactive Aspects of Infant-Adult Communication in a Pathological Perspective2005Inngår i: Proceedings, FONETIK 2005 / [ed] Eriksson, A & Lindh, J., Göteborg: Göteborgs universitet, Institutionen för lingvistik , 2005, s. 55-58Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This is a preliminary report of a study of some linguistic and interactive aspects available in an adult-child dyad where the child is partially hearing impaired, during the ages 8 - 20 months. The investigation involves a male child, born with Hemifacial Microsomia. Audio and video recordings are used to collect data on child vocalization and parent-child interaction. Eye-tracking is used to measure eye movements when presented with audio-visual stimuli. SECDI forms are applied to observe the development of the child's lexical production. Preliminary analyses indicate increased overall parental interactive behaviour. As babbling is somewhat delayed due to physical limitations, signed supported Swedish is used to facilitate communication and language development. Further collection and analysis of data is in progress in search of valuable information of the linguistic development from a pathological perspective of language acquisition.

    Potential relevance of general purpose mechanisms to the onset of language: Audio-visual integration of object attributes2005Inngår i: ESF Research Conference on Brain Development and Cognition in Human Infants, Acquafredda di Maratea, October 1-6, 2005, .: From Action to Cognition, 2005Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The paper addresses the issue of extraction of implicit information conveyed by systematic audio-visual contingencies. A group of infants was tested, with help of the Eye-Tracking analysis system, on a simple inference task provided by short film sequences. The video sequences displayed geometrical objects while the audio played two-word utterances, spoken in an artificial language mimicking the Swedish phonotactics, implicitly referring to the different shapes and colours of the objects. The films were initiated with a static baseline image where the display was divided in four quadrants showing four objects, one in each quadrant. This initial procedure was intended to measure the subject’s spontaneous looking preference towards each of the objects.  Finally after the exposure phase, a test phase was initiated where questions equivalent to “Can you see a cube?” or “Can you see the red (one)?” spoken in the artificial language were asked. At this point the results suggest that the subjects are efficient at picking up the underlying information structure. Further analyses are expected to show more differentiated picture regarding the performance of infants of different age as well as generalization of nouns and adjectives. This is currently being analyzed and will be reported at the conference.

    Estimates of Infants’ Vocabulary Composition and the Role of Adult-instructions for Early Word-learning2007Inngår i: Speech, Music and Hearing, Quarterly Progress and Status Report, TMH-QPSR, Proceedings from Fonetik 2007, May 30 - June 1, 2007. / [ed] Björn Granström, Anna Hjalmarsson, David House, Prebe Wik, Stockholm: Department of Speech, Music and Hearing, KHT, Printed by Universitetsservice AB , 2007, s. 53-56Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The purpose of this study was to assess characteristics of the growth of language in Swedish 7-15 months-old infants. More scpecifically, to estimate vocabulary composition (the 1st part of the study), information on 24 infants’ comprehension and production of speech was collected, and to investigate the role of adult-instructions for early word-learning ( the 2nd part of the study) video recordings of infant-adult interaction-dyads were produced. The vocabulary-data were collected based on parental reports using the Swedish version of the MacArthur Communicative Development Inventory. The subjects’ size of receptive and productive vocabulary across five semantic categories were estimated in a longitudinal perspective based on 45 completed forms. The infant-adult interaction data was likewise collected in a longitudinal perspective. The variables chosen for analyses of infant-adult interaction were: objective of the parent’s gestural instruction, objective of the parent’s vocal instruction, and focus of attention of the infant. The 1st part of the study showed an immense progress for comprehension within the receptive semantic categories of ‘phrases’ and ‘sounds’. The results for the 2nd part of the study showed a shift along a time axis from gestural instructions being mostly correlated with the attentional focus of the infant (at 7 months) to gestural and vocal instructions being equally common (at 15 months). A discussion on significance of these results will round off the paper.

    Major parts-of-speech in child language – division in open and close class words2009Inngår i: Proceedings of Fonetik 2009: The 22nd Swedish Phonetic Conference / [ed] Peter Branderud, Francisco Lacerda, Hartmut Traunmuller, Stockholm, Sweden: Universitetsservice US-AB , 2009, s. 126-129Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The purpose of this study was to assess relations between major parts-of-speech in 14-to 43-months-old infants. Therefore a division in open class and close class words was made. Open class words consist of nouns, verbs and adjectives, while the group of close class words is mainly constituted of grammatical words such as conjunctions, prepositions and adverbs. The data was collected using the Swedish Early Communicative Development Inventory, a version of the MacArthur Communicative Development Inventory. The number of open and close class words was estimated by summarizing items from diverse semantic categories. The study was performed as a mixture of longitudinal and cross-sectional data based on 28 completed forms. The results showed that while the total number of items in the children’s vocabularies grew as the child got older; the proportional division in open vs. close class words – proximally 90-10% – was unchanged.

    Development of communicative skills in 8- to 16-month-old children: A longitudinal study2008Inngår i: Proceedings of The 9th International Conference on Spoken Language Processing, Interspeech2008, Brisbane, September, 2008., 2008, s. 1972-1975Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The aim of this study was to assess development of communicative skills in 8- to 16-month-old children. Information on 24 Swedish children’s speech comprehension and production, as well as their utilization of communicative gestures was collected. A version of the MacArthur Communicative Development Inventory, the Swedish Early Communicative Development Inventory (SECDI), was used. The number of comprehended phrases, size of receptive and productive vocabularies, as well as the subjects’ gesture score was estimated according to standardized scoring instructions. The study was performed longitudinally based on 71 completed forms. The children’s performance was validated with existing norm-data collected from a large set of randomly selected children. The results showed an overall agreement with the norm-data. The performance of the subjects was though less stable and delayed about one month was compared to the norm-data. Adequacy of SECDI for screening language delay is discussed.

    Cross-language analysis of phonetic units in language addressed to infants.1997Inngår i: Science, ISSN 0036-8075, Vol. 277, nr 5326, s. 684-6Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In the early months of life, infants acquire information about the phonetic properties of their native language simply by listening to adults speak. The acoustic properties of phonetic units in language input to young infants in the United States, Russia, and Sweden were examined. In all three countries, mothers addressing their infants produced acoustically more extreme vowels than they did when addressing adults, resulting in a "stretching" of vowel space. The findings show that language input to infants provides exceptionally well-specified information about the linguistic units that form the building blocks for words.

    Emerging linguistic functions in early infancy2005Inngår i: Epigenetic and Robotics: Nara, Japan, 2005, 2005, s. 8-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents results from experimental studies on early language acquisition in infants and attempts to interpret the experimental results within the framework of the Ecological Theory of Language Acquisition (ETLA) recently proposed by (Lacerda et al., 2004a). From this perspective, the infant's first steps in the acquisition of the ambient language are seen as a consequence of the infant's general capacity to represent sensory input and the infant's interaction with other actors in its immediate ecological environment. On the basis of available experimental evidence, it will be argued that ETLA offers a productive alternative to traditional descriptive views of the language acquisition process by presenting an operative model of how early linguistic function may emerge through interaction.

    An Ecological Theory of Language Acquisition2006Inngår i: Linguística: Revista de Estudos Linguísticos da Universidade do Porto, ISSN 1646-6195, Vol. 1, nr 1, s. 54-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    An ecological approach to early language acquisition is presented in this article. The general view is that the ability of language communication must have arisen as an evolutionary adaptation to the representational needs of Homo sapiens and that about the same process is observed in language acquisition, although under different ecological settings. It is argued that the basic principles of human language communication are observed even in non-human species and that it is possible to account for the emergence of an initial linguistic referential function on the basis of general-purpose perceptual, production and memory mechanisms, if there language learner interacts with the ecological environment. A simple computational model of how early language learning may be initiated in today's human infants is proposed.

    Development of lateralised speech perception: Brain activation in 4-month-olds and adults2008Inngår i: Papers from the first Birgit Rausing Language Program Conference in Linguistics, Lund, June 2008 / [ed] Kai-Uwe Alter, Lund: Centre for Languages and Literature, Lund University , 2008, s. 45-46Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Previous fMRI and PET studies indicated left hemispheric activation for the processing of speech and phonetic features, and right hemispheric activation for the processing of emotions and melody. EEG measures are not commonly employed in lateralisation research, neither has lateralisation been extensively investigated in a developmental perspective. This study aims to fill this gap. Although ERP measures cannot precisely localize task-activated cortical regions, differences in voltage reflect scalp electricity in response to the activation of a distinct neural network (Giard et al., 1995). With EEG, we study the lateralisation of speech processing in 4- and 9-month-olds and adults in two conditions, spoken sentences and their spectrally rotated version. Rotating is a technique to render speech intelligible while preserving language-specific characteristics such as rhythm. A previous EEG study showed no lateralisation in 4-month-olds for the processing of speech versus nonspeech sounds as measured with 65 electrodes (Dehaene-Lambertz, 2000). For refined measurement, we employ 128 electrodes and use infant-directed speech stimuli for both conditions. It has been established that language comprehension tasks elicit bilateral hemispheric activation (Awad, Warren, Scott, Turkheimer, & Wise, 2007; Davis et al., 2007), showing intrahemispheric localisation differences within the left hemisphere for phonetic features and comprehension in speech processing tasks (Obleser, Zimmermann, Van Meter, & Rauschecker, 2007; Scott, Blank, Rosen, & Wise, 2000). As sentence comprehension increases with age, we predict an increase of activation in the left hemisphere when comparing 4- to 9-month-olds and 9-month-olds to adults. The melodic and emotional components of the infant-directed speech stimuli should elicit right-hemispheric activation which is predicted to decrease with age. Therefore, the measured differences between left- and right-hemispheric activation are predicted to increase with age. Left-hemispheric activation is also expected for the rotated speech condition due to the speech-likeness of the stimuli, however to a lesser degree than in the natural sentence condition (Ischebeck, Friederici, & Alter, 2007). This activation difference between the speech and rotated speech conditions should also increase with age as comprehension increases. The results are presented in regard to these hypotheses and discussed in the light of recent research.

    Brain responses to typical mispronunciations among toddlers2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In first language acquisition research, investigations on the semantics and lexicon of the child are often conducted by measuring brain activity at the surface of the scalp (EEG). Such EEG studies have shown different brain reactions to matching and mismatching pairs of pictures and words from 19-month-olds (Friedrich & Friederici, 2005). Similarly, results from 20-month-olds exposed to auditory stimuli only indicated different brain reactions to correct pronunciations and mispronunciations (Mills et al., 2004). However, these studies do not take the typical production patterns in that specific age into account.

    In the present study, we measured brain reactions of 13 24-month-olds exposed to pairs of pictures and words in four different conditions: correctly pronounced words, two different kinds of mispronounced words, and novel words. The first type of mispronunciations (M1) consisted in minor mispronunciations consistent with typical production patterns in first language acquisition, e.g. ‘ko’ instead of ‘sko’ (shoe). The second type (M2) was characterized by phonological changes that are not expected at 24 months, e.g. ‘fo’ instead of ‘sko’ (shoe). The novel words consisted of phonotactically possible Swedish non-words.

    A principal component analysis (PCA) decomposition of the EEG data showed two patterns of posterior negativity typical of lexical-semantic processing: one for novel words in comparison to the other conditions, and the other for novel and M2 word forms compared to M1 and correct word forms. These results indicate that M1 are processed similar as correct word forms, and that M2 and novel words are processed alike. However, while these patterns were visually salient in successive components, the results were not statistically significant. We suspect that the non-significant results were due to the small dataset. Nevertheless, this study contributes to the discussion on the relationship between perception and production in first language acquisition.

    Mother tongue - Phonetic Aspects of Infant-Directed Speech1998Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Phonetic aspects of mother-infant interaction are discussed in light of a functionalist Mother-infant phonetic interaction (MIPhI) model. Adults addressing infants typically use a speech style (infant-directed speech, IDS) characterized by, for instance, extensive suprasegmental (prosodic) modulations. This type of speech seems to interest young infants whose active experience with the spoken language appears to focus their speech perception on the phonological properties of the ambient language during the first year of life.

    This thesis consists of four articles discussing phonetic modifications at the suprasegmental, segmental and phonological levels, based on data from six Swedish mothersí IDS to their 3-month-olds. The first study concerns the tonal word accent 2 in disyllabic words, and shows how the lexical, bimodal, tonal characteristics of this accent are enhanced in IDS as compared to adult-directed speech (ADS). The second is a cross-linguistic investigation of vowel formant frequencies in Swedish, Am. English and Russian IDS. It shows that vowels like /i/, /u/, and /a/ are more clearly separated in IDS than in ADS, in all three languages. The third study addresses the voiced /voiceless contrast in stop consonants as measured by voice onset time (VOT) and shows that stop consonants seem to be poorly separated in early IDS samples. The fourth study investigates the quantity distinction in V:C and VC: sequences and indicates that this phonological contrast is well maintained in the IDS.

    Adult data are discussed within the MIPhI model, assuming that suprasegmental and segmental specifications in IDS follow different phonetic specification paths adapted to the infantsí capacities as these develop over the first 18 months of life. The adultsí phonetic adaptations appear to reflect a selective strategy of presenting linguistic structure in a ìgift-wrappingî that is attractive and functional for the infant.

    Acoustic characteristics of onomatopoetic expressions in child-directed speech2009Inngår i: Proceedings, FONETIK 2009 / [ed] P. Branderud, F. Lacerda, H. Traunmuller, 2009, s. 40-41Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The purpose of this study was to identify preliminary acoustic and phonological characteristics of onomatopoetic expressions (OE) in Swedish child-directed speech. The material of a mother interacting with her 4-year-old child were transcribed and used for pitch contour measurements on OE. Measurements were also made on some non-onomatopoetic expressions to be used as controls. The results showed that OE were often composed of CV or CVC syllables, as well as that the syllables or words of the expressions were usually reduplicated. Also, the mother’s voice was often modified when OE were used. It was common that the quality of the voice was creaky or that the mother whispered these expressions. There were also changes in intonation and some of the expressions had higher fundamental frequency (f0) as compared to non-onomatopoetic expressions. In several ways then, OE can be seen as highly modified child-directed speech.

    A longitudinal study on early gestures and lexical development: A longitudinal case study on the relationship between early gestures and lexical development2011Inngår i: Proceedings of the 17th International Congress of Phonetic Sciences, 17-21 August, 2011. Hong Kong, China / [ed] Wai-Sum Lee and Eric Zee, 2011, s. 1922-1925Konferansepaper (Fagfellevurdert)
    Abstract [en]

    It has been suggested that children who are early or frequent users of gestures also develop expressive language at an early age. This assumption has been questioned on the grounds that studies performed under controlled laboratory conditions in which gestures are elicited in the absence of contextual support (e.g. in relation to a new object) have shown to correlate positively to vocabulary size, while parent observations of gestural behavior performed with associated objects in naturalistic settings have not. The current longitudinal case study of infants’ early gestural and linguistic development is based on parent reports collected by the standardized Swedish analog of MacArthur Communicative Development Inventory (CDI). Results showed that a positive correlation between frequency of use of early gestures andocabulary size could be found for a subset of subjects.
