Autism Traits and Cognitive Performance: Mediating Roles of Sleep Disturbance, Anxiety and Depression / Eunro LEE ; Robin LAYCOCK in Journal of Autism and Developmental Disorders, 53-12 (December 2023)

We investigated potential mediations of common ASD comorbidities in the relationship between sub-clinical autism traits and cognitive performance using an international community sample. Cognitive tasks assessed working memory [executive functioning (EF) theory], mental state attribution [theory of mind (ToM)], and global/local visual processing [weak central coherence (WCC) theory]. Structural equation modelling (SEM) demonstrated sleep disturbance and anxiety mediated the relationship of autism traits on measures of EF, but not WCC and ToM. This suggests that treating the symptoms of sleep disturbance and anxiety may lead to improvements in working memory.

Self-Rated Social Skills Predict Visual Perception: Impairments in Object Discrimination Requiring Transient Attention Associated with High Autistic Tendency / Robin LAYCOCK in Autism Research, 7-1 (February 2014)  

Public ISBD [article]  inAutism Research > 7-1 (February 2014) . - p.104-111 Titre : Self-Rated Social Skills Predict Visual Perception: Impairments in Object Discrimination Requiring Transient Attention Associated with High Autistic Tendency Type de document : Texte imprimé et/ou numérique Auteurs : Robin LAYCOCK, Auteur ; Alana Jade CROSS, Auteur ; Felicity DALLE NOGARE, Auteur ; Sheila Gillard CREWTHER, Auteur Article en page(s) : p.104-111 Langues : Anglais (eng) Mots-clés : autism  dorsal stream  ventral stream  object discrimination  attention Index. décimale : PER Périodiques Résumé : Autism is usually defined by impairments in the social domain but has also been linked to deficient dorsal visual stream processing. However, inconsistent findings make the nature of this relationship unclear and thus, we examined the role of stimulus-driven transient attention, presumably activated by the dorsal stream in autistic tendency. Contrast thresholds for object discrimination were compared between groups with high and low self-rated autistic tendency utilizing the socially based Autism Spectrum Quotient (AQ). Visual stimuli were presented with either abrupt or with ramped contrast onsets/offsets in order to manipulate the demands of transient attention. Larger impairments in performance of abrupt compared with ramped object presentation were established in the high AQ group. Furthermore, self-reported social skills predicted abrupt task performance, suggesting an important visual perception deficiency in autism-related traits. Autism spectrum disorder may be associated with reduced utilization of the dorsal stream to rapidly activate attention prior to ventral stream processing when stimuli are transient.
