Titre : Intact Facial Adaptation in Autistic Adults Type de document : Texte imprimé et/ou numérique Auteurs : Richard COOK, Auteur ; Rebecca BREWER, Auteur ; Punit SHAH, Auteur ; Geoffrey BIRD, Auteur Année de publication : 2014 Article en page(s) : p.481-490 Langues : Anglais (eng) Mots-clés : autism adaptation aftereffects facial identity facial expressions Index. décimale : PER Périodiques Résumé : Adaptation paradigms seek to bias subsequently viewed stimuli through prolonged exposure to an adapting stimulus, thereby giving rise to an aftereffect. Recent experiments have found that children with autism spectrum disorders (ASD) show reduced facial aftereffects, prompting some researchers to speculate that all individuals with ASD exhibit deficient facial adaptation. However, caution is required when generalizing findings from samples of children with ASD to the wider ASD population. The reduced facial aftereffects seen in child samples may instead reflect delayed or atypical developmental trajectories, whereby individuals with ASD are slower to develop adaptive mechanisms. In the present study, two experiments were conducted to determine whether high-functioning adults with ASD also show diminished aftereffects for facial identity and expression. In Experiment 1, using a procedure that minimized the contribution of low-level retinotopic adaptation, we observed substantial aftereffects comparable to those seen in matched controls, for both facial identity and expression. A similar pattern of results was seen in Experiment 2 using a revised procedure that increased the contribution of retinotopic adaptation to the facial aftereffects observed. That adults with autism can show robust facial aftereffects raises the possibility that group differences are seen only at particular points during development, and may not be a lifelong feature of the condition.

Titre : Expression Recognition Difficulty Is Associated with Social But Not Attention-to-Detail Autistic Traits and Reflects Both Alexithymia and Perceptual Difficulty Type de document : Texte imprimé et/ou numérique Auteurs : E. BOTHE, Auteur ; R. PALERMO, Auteur ; G. RHODES, Auteur ; N. BURTON, Auteur ; L. JEFFERY, Auteur Article en page(s) : p.4559-4571 Langues : Anglais (eng) Mots-clés : Adaptive norm-based coding Aftereffects Alexithymia Autism Autistic-like traits Emotion Expression recognition Facial expression Individual differences Index. décimale : PER Périodiques Résumé : Autistic people often show difficulty with facial expression recognition. However, the degree of difficulty varies widely, which might reflect varying symptom profiles. We examined three domains of autistic traits in the typical population and found that more autistic-like social skills were associated with greater difficulty labelling expressions, and more autistic-like communication was associated with greater difficulty labelling and perceptually discriminating between expressions. There were no associations with autistic-like attention to detail. We also found that labelling, but not perceptual, difficulty was mediated by alexithymia. We found no evidence that labelling or perceptual difficulty was mediated by weakened adaptive coding. Results suggest expression recognition varies between the sub-clinical expressions of autistic symptom domains and reflects both co-occurring alexithymia and perceptual difficulty.
