Autistic Traits are Associated with Less Precise Perceptual Integration of Face Identity / Kaitlyn TURBETT in Journal of Autism and Developmental Disorders, 52-5 (May 2022)
[article]
Titre : Autistic Traits are Associated with Less Precise Perceptual Integration of Face Identity Type de document : Texte imprimé et/ou numérique Auteurs : Kaitlyn TURBETT, Auteur ; Linda JEFFERY, Auteur ; Jason BELL, Auteur ; Jessamy BURTON, Auteur ; Romina PALERMO, Auteur Article en page(s) : p.2168-2179 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/complications/diagnosis Autistic Disorder/complications Face Facial Recognition Head Humans Autism Autistic traits Face recognition Facial identity Individual differences Serial dependence Index. décimale : PER Périodiques Résumé : Face recognition difficulties are common in autism and could be a consequence of perceptual atypicalities that disrupt the ability to integrate current and prior information. We tested this theory by measuring the strength of serial dependence for faces (i.e. how likely is it that current perception of a face is biased towards a previously seen face) across the broader autism phenotype. Though serial dependence was not weaker in individuals with more autistic traits, more autistic traits were associated with greater integration of less similar faces. These results suggest that serial dependence is less specialised, and may not operate optimally, in individuals with more autistic traits and could therefore be a contributing factor to autism-linked face recognition difficulties.

In addition, little research has examined how face-viewing is modulated by the emotional expression of the stimuli, in individuals with or without ASD. We used eye-tracking to explore viewing patterns during perception of dynamic emotional facial expressions in relatively large groups of individuals with (n?=?57) and without ASD (n?=?58) and examined diagnostic- and age-related effects, after subgrouping children and adolescents (?18 years), on the one hand, and adults (>18 years), on the other. Results showed that children/adolescents with ASD fixated the mouth of happy and angry faces less than their typically developing (TD) peers, and conversely looked more to the eyes of happy faces. Moreover, while all groups fixated the mouth in happy faces more than in other expressions, children/adolescents with ASD did relatively less so. Correlation analysis showed a similar lack of relative orientation towards the mouth of smiling faces in TD children/adolescents with high autistic traits, as measured by the Autism-Spectrum Quotient (AQ). Among adults, participants with ASD only attended less to the eyes for neutral faces. Our study shows that the emotional content of a face influences gaze behaviour, and that this effect is not fully developed in children/adolescents with ASD. Interestingly, this lack of differentiation observed in the younger ASD group was also seen in younger TD individuals with higher AQ scores.

Langues : Anglais (eng) Mots-clés : Adolescent Adult Autism Spectrum Disorder/physiopathology Child Electroencephalography Evoked Potentials Face Fathers Humans Male Middle Aged Pattern Recognition, Visual Siblings Young Adult Autistic disorder erp Electrophysiology Endophenotype N170 Index. décimale : PER Périodiques Résumé : Background: Inherited abnormalities of perception, recognition, and attention to faces have been implicated in the etiology of autism spectrum disorders (ASD) including abnormal components of event-related brain potentials (ERP) elicited by faces. Methods: We examined familial aggregation of face processing ERP abnormalities previously implicated in ASD in 49 verbal individuals with ASD, 36 unaffected siblings (US), 18 unaffected fathers (UF), and 53 unrelated controls (UC). The ASD, US, and UC groups ranged in age from 12 to 21 years, the UF group ranged in age from 30 to 56 years. ERP responses to images of upright and inverted faces and houses were analyzed under disparate EEG reference schemes. Results: Face-sensitive features of N170 and P1 were readily observed in all groups. Differences between ASD and control groups depended upon the EEG reference scheme. Notably, the superiority of face over object for N170 latency was attenuated in ASD subjects, but not their relatives; this occurred exclusively with the average reference. The difference in N170 amplitude between inverted and upright faces was reduced in both ASD and US groups relative to UC, but this effect was significant only with the vertex reference. Furthermore, similar group differences were observed for both inverted faces and inverted houses, suggesting a lack of face specificity for the attenuation of the N170 inversion effect in ASD. Conclusion: The present findings refine understanding of face processing ERPs in ASD. These data provide only modest evidence for highly-selective ASD-sensitive ERP features, and underscore the sensitivity of these biomarkers to ERP reference scheme. These schemes have varied across published studies and must be accounted for in future studies of the relationship between these commonly acquired ERP characteristics, genotype, and ASD.

If the distinction of the self from others is a key aspect of social behaviour and is a precursory ability of later conceptual self development, it is interesting to investigate these functions in children with autism spectrum disorder (ASD). Here we investigate the implicit access to self representation in children with autism spectrum disorder (ASD) and in children with typical development (TD). Children with ASD were submitted to a visual matching-to-sample task with stimuli depicting their own or other people's body or face-parts. Participants were required to decide which of the two vertically aligned images matched the central target stimulus. The performance of children with ASD was compared to the performance of children with typical development (TD). Children with ASD were less accurate compared to children with typical development. Interestingly, children with ASD performed the task better when they visually matched their own, compared to others’ stimuli showing the self-advantage effect, as well as children with TD.

Titre : Autism diagnosis differentiates neurophysiological responses to faces in adults with tuberous sclerosis complex Type de document : Texte imprimé et/ou numérique Auteurs : C. TYE, Auteur ; T. FARRONI, Auteur ; A. VOLEIN, Auteur ; E. MERCURE, Auteur ; L. TUCKER, Auteur ; M. H. JOHNSON, Auteur ; Patrick BOLTON, Auteur Article en page(s) : p.33 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Erp Face Gaze Tuberous sclerosis complex Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is a common and highly heritable neurodevelopmental disorder that is likely to be the outcome of complex aetiological mechanisms. One strategy to provide insight is to study ASD within tuberous sclerosis complex (TSC), a rare disorder with a high incidence of ASD, but for which the genetic cause is determined. Individuals with ASD consistently demonstrate face processing impairments, but these have not been examined in adults with TSC using event-related potentials (ERPs) that are able to capture distinct temporal stages of processing. METHODS: For adults with TSC (n = 14), 6 of which had a diagnosis of ASD, and control adults (n = 13) passively viewed upright and inverted human faces with direct or averted gaze, with concurrent EEG recording. Amplitude and latency of the P1 and N170 ERPs were measured. RESULTS: Individuals with TSC + ASD exhibited longer N170 latencies to faces compared to typical adults. Typical adults and adults with TSC-only exhibited longer N170 latency to inverted versus upright faces, whereas individuals with TSC + ASD did not show latency differences according to face orientation. In addition, individuals with TSC + ASD showed increased N170 latency to averted compared to direct gaze, which was not demonstrated in typical adults. A reduced lateralization was shown for the TSC + ASD groups on P1 and N170 amplitude. CONCLUSIONS: The findings suggest that individuals with TSC + ASD may have similar electrophysiological abnormalities to idiopathic ASD and are suggestive of developmental delay. Identifying brain-based markers of ASD that are similar in TSC and idiopathic cases is likely to help elucidate the risk pathways to ASD.
