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)  

Public ISBD [article]  inAutism Research > 14-5 (May 2021) . - p.897-910 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.

Brief Report: Patterns of Eye Movements in Face to Face Conversation are Associated with Autistic Traits: Evidence from a Student Sample / Andrius VABALAS in Journal of Autism and Developmental Disorders, 46-1 (January 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-1 (January 2016) . - p.305-314 Titre : Brief Report: Patterns of Eye Movements in Face to Face Conversation are Associated with Autistic Traits: Evidence from a Student Sample Type de document : Texte imprimé et/ou numérique Auteurs : Andrius VABALAS, Auteur ; Megan FREETH, Auteur Année de publication : 2016 Article en page(s) : p.305-314 Langues : Anglais (eng) Mots-clés : Social attention  Mobile eye-tracking  Eye movements  Autistic traits Index. décimale : PER Périodiques Résumé : The current study investigated whether the amount of autistic traits shown by an individual is associated with viewing behaviour during a face-to-face interaction. The eye movements of 36 neurotypical university students were recorded using a mobile eye-tracking device. High amounts of autistic traits were neither associated with reduced looking to the social partner overall, nor with reduced looking to the face. However, individuals who were high in autistic traits exhibited reduced visual exploration during the face-to-face interaction overall, as demonstrated by shorter and less frequent saccades. Visual exploration was not related to social anxiety. This study suggests that there are systematic individual differences in visual exploration during social interactions and these are related to amount of autistic traits.

Cognitive Perspective-Taking During Scene Perception in Autism Spectrum Disorder: Evidence From Eye Movements / Sheena K. AU-YEUNG in Autism Research, 7-1 (February 2014)  

Public ISBD [article]  inAutism Research > 7-1 (February 2014) . - p.84-93 Titre : Cognitive Perspective-Taking During Scene Perception in Autism Spectrum Disorder: Evidence From Eye Movements Type de document : Texte imprimé et/ou numérique Auteurs : Sheena K.

In the current study, participants viewed house scenes with either non-perspective-taking (look for valuable items/features of the house that need fixing) or perspective-taking instructions (imagine that you are a burglar/repairman) while their eye movements were recorded. The eye movement measures revealed that for the “look for the valuable items” and burglar perspective task, the ASD group showed typical relevance effects (the preference to look at schema-relevant compared with schema-irrelevant targets) in their eye movements. However, we found subtle processing differences between the groups that were related to initial orienting to and processing of schema-relevant items for the “look for the features that need fixing” and the repairman perspective-taking task. There was an absence of a relevance effect for the ASD group for the repairman perspective and its non-perspective-taking equivalent instruction showing that the identification of items relevant to those schemas was more difficult for the ASD group. The present findings suggest that resolving ambiguity may be a defining feature of complex information processing deficits in ASD.

Looking, seeing and believing in autism: Eye movements reveal how subtle cognitive processing differences impact in the social domain / Valerie BENSON in Autism Research, 9-8 (August 2016)

The task was to indicate, using a button press, whether the pictures were normal, or in some way weird or odd. Oddities in the pictures were categorized as violations of either perceptual or social norms. Compared to a Typically Developed (TD) control group, the ASD participants were equally able to categorize the scenes as odd or normal, but they took longer to respond. The eye movement patterns showed that the ASD group made more fixations and revisits to the target areas in the odd scenes compared with the TD group. Additionally, when the ASD group first fixated the target areas in the scenes, they failed to initially detect the social oddities. These two findings have clear implications for processing difficulties in ASD for the social domain, where it is important to detect social cues on-line, and where there is little opportunity to go back and recheck possible cues in fast dynamic interactions.

Visual and Vestibular Induced Eye Movements in Verbal Children and Adults with Autism / Joseph M. FURMAN in Autism Research, 8-6 (December 2015)  

Public ISBD [article]  inAutism Research > 8-6 (December 2015) . - p.658-667 Titre : Visual and Vestibular Induced Eye Movements in Verbal Children and Adults with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Joseph M.

MINSHEW, Auteur Article en page(s) : p.658-667 Langues : Anglais (eng) Mots-clés : autism  ocular motility  brainstem  clinical neurophysiology  eye movements Index. décimale : PER Périodiques Résumé : This study assessed the functionality of vestibular, pursuit, and saccade circuitry in autism across a wide age range. Subjects were 79 individuals with autism (AUT) and 62 controls (CON) aged 5 to 52 years with IQ scores?>?70. For vestibular testing, earth-vertical axis rotation was performed in darkness and in a lighted visual surround with a fixation target. Ocular motor testing included assessment of horizontal saccades and horizontal smooth pursuit. No between-group differences were found in vestibular reflexes or in mean saccade velocity or accuracy. Saccade latency was increased in the AUT group with significant age-related effects in the 8–18 year old subgroups. There was a trend toward decreased pursuit gain without age effects. Normal vestibular-induced eye movements and normal saccade accuracy and velocity provide the most substantial evidence to date of the functional integrity of brainstem and cerebellar pathways in autism, suggesting that the histopathological abnormalities described in these structures may not be associated with intrinsic dysfunction but rather reflect developmental alterations related to forebrain cortical systems formation. Increased saccade latency with age effects adds to the extensive existing evidence of altered function and maturation of cortical systems in autism.
