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.

Eye Gaze in Autism Spectrum Disorder: A Review of Neural Evidence for the Eye Avoidance Hypothesis / Nicole STUART in Journal of Autism and Developmental Disorders, 53-5 (May 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-5 (May 2023) . - p.1884-1905 Titre : Eye Gaze in Autism Spectrum Disorder: A Review of Neural Evidence for the Eye Avoidance Hypothesis Type de document : Texte imprimé et/ou numérique Auteurs : Nicole STUART, Auteur ; Andrew WHITEHOUSE, Auteur ; Romina PALERMO, Auteur ; Ellen BOTHE, Auteur ; Nicholas BADCOCK, Auteur Article en page(s) : p.1884-1905 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Reduced eye contact early in life may play a role in the developmental pathways that culminate in a diagnosis of autism spectrum disorder. However, there are contradictory theories regarding the neural mechanisms involved. According to the amygdala theory of autism, reduced eye contact results from a hypoactive amygdala that fails to flag eyes as salient. However, the eye avoidance hypothesis proposes the opposite-that amygdala hyperactivity causes eye avoidance. This review evaluated studies that measured the relationship between eye gaze and activity in the 'social brain' when viewing facial stimuli. Of the reviewed studies, eight of eleven supported the eye avoidance hypothesis. These results suggest eye avoidance may be used to reduce amygdala-related hyperarousal among people on the autism spectrum.
