Autistic-like traits in children are associated with enhanced performance in a qualitative visual working memory task / C. J. HAMILTON in Autism Research, 11-11 (November 2018)
[article]
Titre : Autistic-like traits in children are associated with enhanced performance in a qualitative visual working memory task Type de document : Texte imprimé et/ou numérique Auteurs : C. J. HAMILTON, Auteur ; I. C. MAMMARELLA, Auteur ; D. GIOFRE, Auteur Article en page(s) : p.1494-1499 Langues : Anglais (eng) Mots-clés : broader autism phenotype children cognition long-term memory visual working memory Index. décimale : PER Périodiques Résumé : Prior research has suggested that individuals with Autism Spectrum Disorders (ASD) demonstrate heterogeneity in cognitive efficacy, challenged executive resources but efficient visual processing. These contrasts lead to opposing predictions about visuospatial working memory competency in both ASD and the broader autism phenotype (BAP); compromised by constrained executive processes, but potentially scaffolded by effective visual representation. It is surprising therefore, that there is a paucity of visual working memory (VWM) research in both the ASD and BAP populations, which have focused upon the visual features of the to-be-remembered stimulus. We assessed whether individual differences in VWM were associated with autistic-like traits (ALTs) in the BAP. About 76 children carried out the Visual Just Noticeable Difference task, designed to measure high fidelity feature representation within VWM. ALTs were measured with the Children's Empathy Quotient and Systemizing Quotient. Analyses revealed a significant positive relationship between Systemizing and VWM performance. This complements ASD studies in visual processing and highlights the need for further research on the working memory-long-term memory interface in ASD and BAP populations. Autism Research 2018, 11: 1494-1499. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This study was interested in how well children with high levels of autistic-like traits (ALTs) carry out a task which involved memorizing, for brief time, the precise size of colored shapes. The results suggested that children with high levels of ALTs performed the task relatively well. This finding is in contrast to many previous studies suggest that ALTs are associated with poor memory, and suggests that future research needs to look more finely at how individuals carry out these tasks.
