Altered Dynamics of the fMRI Response to Faces in Individuals with Autism / Natalia M. KLEINHANS in Journal of Autism and Developmental Disorders, 46-1 (January 2016)
[article]
Titre : Altered Dynamics of the fMRI Response to Faces in Individuals with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Natalia M. KLEINHANS, Auteur ; Todd RICHARDS, Auteur ; Jessica GREENSON, Auteur ; Geraldine DAWSON, Auteur ; Elizabeth H. AYLWARD, Auteur Année de publication : 2016 Article en page(s) : p.232-241 Langues : Anglais (eng) Mots-clés : Habituation Faces Houses Amygdala Fusiform Adaptation Index. décimale : PER Périodiques Résumé : Abnormal fMRI habituation in autism spectrum disorders (ASDs) has been proposed as a critical component in social impairment. This study investigated habituation to fearful faces and houses in ASD and whether fMRI measures of brain activity discriminate between ASD and typically developing (TD) controls. Two identical fMRI runs presenting masked fearful faces, houses, and scrambled images were collected. We found significantly slower fMRI responses to fearful faces but not houses in ASD. In addition, the pattern of slow to emerge amygdala activation to faces had robust discriminability [ASD vs. TD; area under the curve (AUC) = .852, p < .001]. In contrast, habituation to houses had no predictive value (AUC = .573, p = .365). Amygdala habituation to emotional faces may be useful for quantifying risk in ASD.

STAGG, Auteur ; Robert DAVIS, Auteur ; Pamela HEATON, Auteur Article en page(s) : p.2303-2311 Langues : Anglais (eng) Mots-clés : Language delay Galvanic skin response Language onset Autism spectrum disorder Faces Eye-gaze Index. décimale : PER Périodiques Résumé : Attention to social stimuli is associated with language development, and arousal is associated with the increased viewing of stimuli. We investigated whether skin conductance responses (SCRs) are associated with language development in autism spectrum disorder (ASD): a population that shows abnormalities in both attention to others and language development. A sample of 32 children with ASD (7–15 year; M = 9 year) was divided into two groups, based on language onset histories. A typically developing comparison group consisted of 18 age and IQ matched children. SCRs were taken as the participants viewed faces. SCRs differentiated the ASD group based on language onset and were associated with abnormal attention to gaze in infancy and subsequent language development.

Titre : Attentional Processing of Faces in ASD: A Dot-Probe Study Type de document : Texte imprimé et/ou numérique Auteurs : David J. MOORE, Auteur ; Lisa HEAVEY, Auteur ; John REIDY, Auteur Année de publication : 2012 Article en page(s) : p.2038-2045 Langues : Anglais (eng) Mots-clés : Autism Attention Social Faces Dot-Probe Index. décimale : PER Périodiques Résumé : The present study used the Dot-Probe paradigm to explore attentional allocation to faces compared with non-social images in high-functioning individuals with autism spectrum disorder (ASD) and typically developing controls. There was no evidence of attentional bias in either group when stimuli were presented at individually calculated sub-threshold levels. However, at supra-threshold presentation (200 ms), a face bias was found for control participants but not for those with ASD. These results add to evidence of reduced social interest in ASD, relative to controls, and further demonstrate when atypical social processing arises in the attentional time course.

The authors have no relevant non-financial interests to disclose. Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) have been found to view social scenes differently compared to typically developing (TD) peers, but results can vary depending on context and age. We used eye-tracking in children and adults (age 6-63) to assess allocation of visual attention in a dynamic social orientation paradigm previously used only in younger children. The ASD group (n=94) looked less at the actor's face compared to TD (n=38) when they were engaged in activity (mean percentage of looking time, ASD=30.7% vs TD=34.9%; Cohen's d=0.56; p value<0.03) or looking at a moving toy (24.5% vs 33.2%; d=0.65; p value<0.001). Findings indicate that there are qualitative differences in allocation of visual attention to social stimuli across ages in ASD.ClinicalTrials.gov identifier: NCT02668991.

Titre : Infants' neural responses to emotional faces are related to maternal anxiety Type de document : Texte imprimé et/ou numérique Auteurs : L. C. BOWMAN, Auteur ; S. A. MCCORMICK, Auteur ; Finola KANE-GRADE, Auteur ; W. XIE, Auteur ; Michelle BOSQUET ENLOW, Auteur ; C. A. NELSON, Auteur Article en page(s) : p.152-164 Langues : Anglais (eng) Mots-clés : Eeg/erp Maternal anxiety N290 Nc P400 emotions faces infants Index. décimale : PER Périodiques Résumé : BACKGROUND: Postnatal maternal anxiety is common (estimates as high as 40% prevalence) and is associated with altered mother-infant interactions (e.g., reduced maternal emotional expression and engagement). Neural circuitry supporting infants' face and emotion processing develops in their first year. Thus, early exposure to maternal anxiety may impact infants' developing understanding of emotional displays. We examine whether maternal anxiety is associated with individual differences in typically developing infants' neural responses to emotional faces. METHODS: One hundred and forty two mother-infant dyads were assessed when infants were 5, 7, or 12?months old. Infants' electroencephalographic (EEG) data were recorded while passively viewing female happy, fearful, and angry faces. Three event-related potential (ERP) components, each linked to face and emotion processing, were evaluated: NC, N290, and P400. Infant ERP amplitude was related to concurrent maternal-report anxiety assessed with the Spielberger State-Trait Anxiety Inventory (Trait form). RESULTS: Greater maternal anxiety predicted more negative NC amplitude for happy and fearful faces in left and mid-central scalp regions, beyond covarying influences of maternal depression symptoms, infant negative emotionality, and infant age. CONCLUSIONS: Postnatal maternal anxiety is related to infants' neural processing of emotional expressions. Infants of mothers endorsing high trait anxiety may need additional attentional resources to process happy and fearful faces (expressions less likely experienced in mother-infant interactions). Future research should investigate mechanisms underlying this association, given possibilities include experiential, genetic, and prenatal factors.
