Action prediction in 10-month-old infants at high and low familial risk for Autism Spectrum Disorder / Ricarda BRAUKMANN in Research in Autism Spectrum Disorders, 49 (May 2018)
[article]
Titre : Action prediction in 10-month-old infants at high and low familial risk for Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Ricarda BRAUKMANN, Auteur ; Emma K. WARD, Auteur ; Roy S. HESSELS, Auteur ; Harold BEKKERING, Auteur ; Jan K. BUITELAAR, Auteur ; Sabine HUNNIUS, Auteur Article en page(s) : p.34-46 Langues : Anglais (eng) Mots-clés : Eye tracking Infant Siblings ASD Action prediction Index. décimale : PER Périodiques Résumé : Background Several studies have reported action prediction difficulties in Autism Spectrum Disorder (ASD). Although action prediction develops in infancy, little is known about prediction abilities in infants at risk for ASD. Methods Using eye tracking, we measured action anticipations in 52 10-month-old infants at high and low familial risk for ASD. Infants were repeatedly presented with actions during which a familiar object (cup/phone) was either brought to a location usually associated with the object (cup-to-mouth/phone-to-ear; usual condition) or to an unusual location (cup-to-ear/phone-to-mouth; unusual condition). We assessed infants’ anticipations to the actual target location (i.e., the location where the object was actually brought; the mouth in cup-to-mouth/phone-to-mouth actions; the ear in cup-to-ear/phone-to-ear actions) and the alternative target location (the ear in cup-to-mouth/phone-to-mouth actions; the mouth in cup-to-ear/phone-to-ear actions). Results Anticipation frequencies were modulated by object knowledge across all infants: We found more frequent anticipations towards the alternative target location for unusual compared to usual actions. This effect was in particular present for mouth anticipations which were also overall more frequent than ear anticipations. Across usual and unusual actions, infants showed more frequent anticipations towards the actual target location, potentially representing a learning effect elicited by the repeated action presentation. Importantly, there were no differences between the low- and high-risk infants in predictive eye movements. Conclusion Whereas our results suggest that familial risk for ASD does not affect action prediction in infancy, future research needs to investigate whether differences are apparent in those high-risk infants who later receive a diagnosis.

Titre : Is It Fear? Similar Brain Responses to Fearful and Neutral Faces in Infants with a Heightened Likelihood for Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Renata DI LORENZO, Auteur ; Nicolette M. MUNSTERS, Auteur ; Emma K. WARD, Auteur ; Maretha DE JONGE, Auteur ; Chantal KEMNER, Auteur ; Carlijn VAN DEN BOOMEN, Auteur Article en page(s) : p.961-972 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Emotion Endophenotype Event-related potentials Infants Spatial frequency Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) show atypical processing of facial expressions. Research with autistic toddlers suggests that abnormalities in processing of spatial frequencies (SFs) contribute to such differences. The current event-related-potential (ERP) study investigated differences between 10-month-old infants with high- and low-likelihood for ASD in SF processing and in discrimination of fearful and neutral faces, filtered to contain specific SF. Results indicate no group differences in general processing of higher (HSF, detailed) and lower-SF (LSF, global) information. However, unlike low-likelihood infants, high-likelihood infants do not discriminate between facial expressions when either the LSF or HSF information is available. Combined with previous findings in toddlers, the current results indicate a developmental delay in efficient processing of facial expressions in ASD.
