Eye Movements of Spatial Working Memory Encoding in Children with and without Autism: Chunking Processing and Reference Preference / Songze LI in Autism Research, 14-5 (May 2021)
[article]
Titre : Eye Movements of Spatial Working Memory Encoding in Children with and without Autism: Chunking Processing and Reference Preference Type de document : Texte imprimé et/ou numérique Auteurs : Songze LI, Auteur ; Jinsheng HU, Auteur ; Ruosong CHANG, Auteur ; Qi LI, Auteur ; Peng WAN, Auteur ; Shuqing LIU, Auteur Article en page(s) : p.897-910 Langues : Anglais (eng) Mots-clés : autism chunking encoding eye movements frame of reference spatial working memory weak central coherence Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) experience spatial working memory deficits and show different encoding mechanisms from typical developing (TD) peers. To effectively describe the encoding strategies of those with ASD and highlight their characteristics in cognitive processing, we adopted improved change detection tasks and added eye-movement indicators to investigate the chunking function and reference preference of children with and without ASD. The current study included 20 participants with ASD aged 8-16 and 20 TD children matched for age, gender, and intelligence. Experiment 1 used high/low-structured change detection tasks, and eye-movement indexes were recorded as they memorized the locations of the items to investigate spatial chunking strategies. In Experiment 2, changes in eye movement patterns were observed by adding a frame of reference. The results suggested different encoding strategies in ASD and TD individuals. The ASD group showed local processing bias and had difficulty adopting chunking strategies in spatial working memory. Eye-movement analysis suggested that they rarely showed integrated information processing tendency observed in TD children. Moreover, as a compensatory processing, they were more likely to use the frame of reference. In this study, we compared the spatial chunking strategies and reference preference of children with and without ASD, and eye-movement analysis was used to investigate the processing mechanism. These findings are significant for research on cognitive characteristics of ASD and provide a new focus for working memory training in children with ASD. LAY SUMMARY: The current study suggests that children with autism spectrum disorder are poorer at organizing items into chunks in spatial working memory, but rely more on reference frames. If the purpose of location memory is to strengthen the adaptability of children with autism, it should provide them with more clues or references. If it is for the purpose of intervention such as cognitive training, it should guide them to integrate information to improve the basic cognitive processing efficiency.

Results disclosed subtle group differences regarding response speed on only one CANTAB subtest that is thought to tap fronto-executive network functions (SWM/spatial working memory). Across all participants, SWM performance was significantly associated with two brain regions (precentral gyrus white matter, precuneus grey matter), thus suggesting a close link between fronto-executive functions (SWM) and circumscribed fronto-parietal brain structures. Finally, symptom severity (ADOS total score) was best predicted by response speed on a set-shifting task (IES) thought to tap fronto-striatal functions (corrected R2 56 %).

Titre : Executive function predicts the development of play skills for verbal preschoolers with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Susan FAJA, Auteur ; Geraldine DAWSON, Auteur ; Katherine SULLIVAN, Auteur ; Andrew N. MELTZOFF, Auteur ; Annette ESTES, Auteur ; Raphael BERNIER, Auteur Article en page(s) : p.1274-1284 Langues : Anglais (eng) Mots-clés : autism executive function inhibition spatial working memory play language Index. décimale : PER Périodiques Résumé : Executive function and play skills develop in early childhood and are linked to cognitive and language ability. The present study examined these abilities longitudinally in two groups with autism spectrum disorder—a group with higher initial language (n?=?30) and a group with lower initial language ability (n?=?36). Among the lower language group, concurrent nonverbal cognitive ability contributed most to individual differences in executive function and play skills. For the higher language group, executive function during preschool significantly predicted play ability at age 6 over and above intelligence, but early play did not predict later executive function. These results suggested that factors related to the development of play and executive function differ for subgroups of children with different language abilities and that early executive function skills may be critical in order for verbal children with autism to develop play.
