Early processing (N170) of infant faces in mothers of children with autism spectrum disorder and its association with maternal sensitivity / C. MARQUEZ in Autism Research, 12-5 (May 2019)
[article]
Titre : Early processing (N170) of infant faces in mothers of children with autism spectrum disorder and its association with maternal sensitivity Type de document : Texte imprimé et/ou numérique Auteurs : C. MARQUEZ, Auteur ; H. NICOLINI, Auteur ; M. J. CROWLEY, Auteur ; R. SOLIS-VIVANCO, Auteur Article en page(s) : p.744-758 Langues : Anglais (eng) Mots-clés : N170 autism spectrum disorder event-related potential infant face processing maternal sensitivity mothers Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) exhibit impaired adult facial processing, as shown by the N170 event-related potential. However, few studies explore such processing in mothers of children with ASD, and none has assessed the early processing of infant faces in these women. Moreover, whether processing of infant facial expressions in mothers of children with ASD is related to their response to their child's needs (maternal sensitivity [MS]) remains unknown. This study explored the N170 related to infant faces in a group of mothers of children with ASD (MA) and a reference group of mothers of children without ASD. For both emotional (crying, smiling) and neutral expressions, the MA group exhibited larger amplitudes of N170 in the right hemisphere, while the reference group showed similar interhemispheric amplitudes. This lateralization effect within the MA group was not present for nonfaces and was stronger in the mothers with higher MS. We propose that mothers of ASD children use specialized perceptual resources to process infant faces, and this specialization is mediated by MS. Our findings suggest that having an ASD child modulates mothers' early neurophysiological responsiveness to infant cues. Whether this modulation represents a biological marker or a response given by experience remains to be explored. Autism Research 2019, 12: 744-758. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: When mothers of children with autism spectrum disorder (ASD) see baby faces expressing emotions, they show a right-sided electrical response in the brain. This lateralization was stronger in mothers who were more sensitive to their children's needs. We conclude that having a child with ASD and being more attuned to their behavior generates a specialized pattern of brain activity when processing infant faces. Whether this pattern is biological or given by experience remains to be explored.

Titre : Preserved reward outcome processing in ASD as revealed by event-related potentials Type de document : Texte imprimé et/ou numérique Auteurs : J. C. MCPARTLAND, Auteur ; M. J. CROWLEY, Auteur ; D. R. PERSZYK, Auteur ; C. E. MUKERJI, Auteur ; A. J. NAPLES, Auteur ; J. WU, Auteur ; L. C. MAYES, Auteur Article en page(s) : p.16 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: Problems with reward system function have been posited as a primary difficulty in autism spectrum disorders. The current study examined an electrophysiological marker of feedback monitoring, the feedback-related negativity (FRN), during a monetary reward task. The study advanced prior understanding by focusing exclusively on a developmental sample, applying rigorous diagnostic characterization and introducing an experimental paradigm providing more subtly different feedback valence (reward versus non-reward instead of reward versus loss). METHODS: Twenty-six children with autism spectrum disorder and 28 typically developing peers matched on age and full-scale IQ played a guessing game resulting in monetary gain ("win") or neutral outcome ("draw"). ERP components marking early visual processing (N1, P2) and feedback appraisal (FRN) were contrasted between groups in each condition, and their relationships to behavioral measures of social function and dysfunction, social anxiety, and autism symptomatology were explored. RESULTS: FRN was observed on draw trials relative to win trials. Consistent with prior research, children with ASD exhibited a FRN to suboptimal outcomes that was comparable to typical peers. ERP parameters were unrelated to behavioral measures. CONCLUSIONS: Results of the current study indicate typical patterns of feedback monitoring in the context of monetary reward in ASD. The study extends prior findings of normative feedback monitoring to a sample composed exclusively of children and demonstrates that, as in typical development, individuals with autism exhibit a FRN to suboptimal outcomes, irrespective of neutral or negative valence. Results do not support a pervasive problem with reward system function in ASD, instead suggesting any dysfunction lies in more specific domains, such as social perception, or in response to particular feedback-monitoring contexts, such as self-evaluation of one's errors.

We simultaneously evaluated the contribution of social symptom severity and behavioral movement. Children with AS group showed less psychophysiological reactivity to social threat than controls across all three phases of the experiment. In the AS group, greater social impairment was significantly associated with reduced SCR. However, movement activity predicted SCR while diagnosis did not. Research and treatment need to account for the complex interplay of emotional reactivity and social behavior in AS. Psychophysiology studies of AS should consider the impact of possible confounds such as movement.

Titre : The N170 event-related potential reflects delayed neural response to faces when visual attention is directed to the eyes in youths with ASD Type de document : Texte imprimé et/ou numérique Auteurs : T. C. PARKER, Auteur ; M. J. CROWLEY, Auteur ; A. J. NAPLES, Auteur ; M. J. ROLISON, Auteur ; J. WU, Auteur ; J. A. TRAPANI, Auteur ; J. C. MCPARTLAND, Auteur Article en page(s) : p.1347-1356 Langues : Anglais (eng) Mots-clés : Adolescent Autism Spectrum Disorder Brain Child Evoked Potentials Facial Recognition Humans Eeg N170 autism event-related potential face perception social neuroscience Index. décimale : PER Périodiques Résumé : Atypical neural response to faces is thought to contribute to social deficits in autism spectrum disorder (ASD). Compared to typically developing (TD) controls, individuals with ASD exhibit delayed brain responses to upright faces at a face-sensitive event-related potential (ERP), the N170. Given observed differences in patterns of visual attention to faces, it is not known whether slowed neural processing may simply reflect atypical looking to faces. The present study manipulated visual attention to facial features to examine whether directed attention to the eyes normalizes N170 latency in ASD. ERPs were recorded in 30 children and adolescents with ASD as well as 26 TD children and adolescents. Results replicated prior findings of shorter N170 latency to the eye region of the face in TD individuals. In contrast, those with ASD did not demonstrate modulation of N170 latency by point of regard to the face. Group differences in latency were most pronounced when attention was directed to the eyes. Results suggest that well-replicated findings of N170 delays in ASD do not simply reflect atypical patterns of visual engagement with experimental stimuli. These findings add to a body of evidence indicating that N170 delays are a promising marker of atypical neural response to social information in ASD. LAY SUMMARY: This study looks at how children's and adolescents' brains respond when looking at different parts of a face. Typically developing children and adolescents processed eyes faster than other parts of the face, whereas this pattern was not seen in ASD. Children and adolescents with ASD processed eyes more slowly than typically developing children. These findings suggest that observed inefficiencies in face processing in ASD are not simply reflective of failure to attend to the eyes.
