Atypical sensory reactivity influences auditory attentional control in adults with autism spectrum disorders / Debra S. KARHSON in Autism Research, 9-10 (October 2016)
[article]
Titre : Atypical sensory reactivity influences auditory attentional control in adults with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Debra S. KARHSON, Auteur ; Edward J. GOLOB, Auteur Article en page(s) : p.1079-1092 Langues : Anglais (eng) Mots-clés : P50 P1 N100 autism attention EEG/ERP sensory reactivity Index. décimale : PER Périodiques Résumé : Frequent observations of atypical sensory reactivity in people with autism spectrum disorders (ASD) suggest that the perceptual experience of those on the Spectrum is dissimilar to neurotypicals. Moreover, variable attention abilities in people with ASD, ranging from good control to periods of high distractibility, may be related to atypical sensory reactivity. This study used auditory event-related potential (ERP) measures to evaluate top-down and bottom-up attentional processes as a function of perceptual load, and examined these factors with respect to sensory reactivity. Twenty-five age and IQ-matched participants (ASD: 22.5 year, SD?=?4.1 year; Controls: 22.8 year, SD?=?5.1 year) completed the Adolescent/Adult Sensory Profile prior to performing a modified 3-stimulus (target, non-target, and distractor) auditory oddball target detection task EEG was recorded during task completion. ERP analysis assessed early sensory processing (P50, ?50 ms latency; N100, ?100 ms latency), cognitive control (N200, ?200 ms latency), and attentional processing (P3a and P3b, ?300 ms latency). Behavioral data demonstrates participants with ASD and neurotypical performed similarly on auditory target detection, but diverged on sensory profiles. Target ERP measures associated with top-down control (P3b latency) significantly increased under greater load in controls, but not in participants with ASD. Early ERP responses associated with bottom-up attention (P50 amplitude) were positively correlated to increased sensory sensitivity. Findings suggest specific neural mechanisms for increased perceptual capacity and enhanced bottom-up processing of sensory stimuli in people with autism. Results from participants with ASD are consistent with load theory and enhanced perceptual functioning.

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.
