Ring, Melanie; Gaigg, Sebastian B.; Altgassen, Mareike; Barr, Peter; Bowler, Dermot M. – Journal of Autism and Developmental Disorders, 2018
Individuals with autism spectrum disorder (ASD) present difficulties in forming relations among items and context. This capacity for relational binding is also involved in spatial navigation and research on this topic in ASD is scarce and inconclusive. Using a computerised version of the Morris Water Maze task, ASD participants showed particular…

Vanmarcke, Steven; Noens, Ilse; Steyaert, Jean; Wagemans, Johan – Journal of Autism and Developmental Disorders, 2017
While most typically developing (TD) participants have a coarse-to-fine processing style, people with autism spectrum disorder (ASD) seem to be less globally and more locally biased when processing visual information. The stimulus-specific spatial frequency content might be directly relevant to determine this temporal hierarchy of visual…

Waite, Jane; Beck, Sarah R.; Heald, Mary; Powis, Laurie; Oliver, Chris – Journal of Autism and Developmental Disorders, 2016
Working memory (WM) impairments might amplify behavioural difference in genetic syndromes. Murine models of Rubinstein-Taybi syndrome (RTS) evidence memory impairments but there is limited research on memory in RTS. Individuals with RTS and typically developing children completed WM tasks, with participants with RTS completing an IQ assessment and…

Hadad, Bat-Sheva; Ziv, Yair – Journal of Autism and Developmental Disorders, 2015
We first demonstrated analytic processing in ASD under conditions in which integral processing seems mandatory in TD observers, a pattern that is often taken to indicate a local default processing in ASD. However, this processing bias does not inevitably come at the price of impaired integration skills. Indeed, examining the same group of…

Bowler, Dermot M.; Gaigg, Sebastian B.; Gardiner, John M. – Journal of Autism and Developmental Disorders, 2015
Adults with autism spectrum disorder (ASD) show intact recognition (supported procedure) but impaired recall (unsupported procedure) of incidentally-encoded context. Because this has not been demonstrated for temporal source, we compared the temporal and spatial source memory of adults with ASD and verbally matched typical adults. Because of…

Muth, Anne; Hönekopp, Johannes; Falter, Christine M. – Journal of Autism and Developmental Disorders, 2014
Visuo-spatial skills are believed to be enhanced in autism spectrum disorders (ASDs). This meta-analysis tests the current state of evidence for Figure Disembedding, Block Design, Mental Rotation and Navon tasks in ASD and neurotypicals. Block Design (d = 0.32) and Figure Disembedding (d = 0.26) showed superior performance for ASD with large…

David, Nicole; Schultz, Johannes; Milne, Elizabeth; Schunke, Odette; Schöttle, Daniel; Münchau, Alexander; Siegel, Markus; Vogeley, Kai; Engel, Andreas K. – Journal of Autism and Developmental Disorders, 2014
Individuals with an autism spectrum disorder (ASD) show hallmark deficits in social perception. These difficulties might also reflect fundamental deficits in integrating visual signals. We contrasted predictions of a social perception and a spatial-temporal integration deficit account. Participants with ASD and matched controls performed two…

Pearson, Amy; Marsh, Lauren; Hamilton, Antonia; Ropar, Danielle – Journal of Autism and Developmental Disorders, 2014
Previous research into autism spectrum disorder (ASD) has shown people with autism to be impaired at visual perspective taking. However it is still unclear to what extent the spatial mechanisms underlying this ability contribute to these difficulties. In the current experiment we examine spatial transformations in adults with ASD and typical…

Chabani, Ellahe; Hommel, Bernhard – Journal of Autism and Developmental Disorders, 2014
Individuals with autism spectrum disorders (ASDs) have been assumed to show evidence of abnormal visuospatial processing, which has been attributed to a failure to integrate local features into coherent global Gestalts and/or to a bias towards local processing. As the available data are based on baseline performance only, which does not provide…

Koldewyn, Kami; Weigelt, Sarah; Kanwisher, Nancy; Jiang, Yuhong – Journal of Autism and Developmental Disorders, 2013
Difficulties in visual attention are often implicated in autism spectrum disorders (ASD) but it remains unclear which aspects of attention are affected. Here, we used a multiple object tracking (MOT) task to quantitatively characterize dynamic attentional function in children with ASD aged 5-12. While the ASD group performed significantly worse…

Sachse, Michael; Schlitt, Sabine; Hainz, Daniela; Ciaramidaro, Angela; Schirman, Shella; Walter, Henrik; Poustka, Fritz; Bolte, Sven; Freitag, Christine M. – Journal of Autism and Developmental Disorders, 2013
This study broadly examines executive (EF) and visuo-motor function in 30 adolescent and adult individuals with high-functioning autism spectrum disorder (ASD) in comparison to 28 controls matched for age, gender, and IQ. ASD individuals showed impaired spatial working memory, whereas planning, cognitive flexibility, and inhibition were spared.…

Salowitz, Nicole M. G.; Eccarius, Petra; Karst, Jeffrey; Carson, Audrey; Schohl, Kirsten; Stevens, Sheryl; Van Hecke, Amy Vaughan; Scheidt, Robert A. – Journal of Autism and Developmental Disorders, 2013
Thirteen autistic and 14 typically developing children (controls) imitated hand/arm gestures and performed mirror drawing; both tasks assessed ability to reorganize the relationship between spatial goals and the motor commands needed to acquire them. During imitation, children with autism were less accurate than controls in replicating hand shape,…

Kunda, Maithilee; Goel, Ashok K. – Journal of Autism and Developmental Disorders, 2011
We analyze the hypothesis that some individuals on the autism spectrum may use visual mental representations and processes to perform certain tasks that typically developing individuals perform verbally. We present a framework for interpreting empirical evidence related to this "Thinking in Pictures" hypothesis and then provide…

David, Nicole; Aumann, Carolin; Bewernick, Bettina H.; Santos, Natacha S.; Lehnhardt, Fritz-G.; Vogeley, Kai – Journal of Autism and Developmental Disorders, 2010
Mentalizing refers to making inferences about other people's mental states, whereas visuospatial perspective taking refers to inferring other people's viewpoints. Both abilities seem vital for social functioning; yet, their exact relationship is unclear. We directly compared mentalizing and visuospatial perspective taking in nineteen adults with…

Cui, Jifang; Gao, Dingguo; Chen, Yinghe; Zou, Xiaobing; Wang, Ya – Journal of Autism and Developmental Disorders, 2010
Using a battery of working memory span tasks and n-back tasks, this study aimed to explore working memory functions in early-school-age children with Asperger's syndrome (AS). Twelve children with AS and 29 healthy children matched on age and IQ were recruited. Results showed: (a) children with AS performed better in digit and word recall tasks,…
