Neely, Kristina A.; Mohanty, Suman; Schmitt, Lauren M.; Wang, Zheng; Sweeney, John A.; Mosconi, Matthew W. – Journal of Autism and Developmental Disorders, 2019
Sensorimotor abnormalities are common in individuals with autism spectrum disorder (ASD); however, the processes underlying these deficits remain unclear. This study examined force production with and without visual feedback to determine if individuals with ASD can utilize internal representations to guide sustained force. Individuals with ASD…

McMorris, Carly A.; Brown, Stephanie M.; Bebko, James M. – Journal of Autism and Developmental Disorders, 2013
"Iconic memory" is the ability to accurately recall a number of items after a very brief visual exposure. Previous research has examined these capabilities in typically developing (TD) children and individuals with intellectual disabilities (ID); however, there is limited research on these abilities in children with Autism Spectrum…

Koolen, Sophieke; Vissers, Constance Th. W. M.; Egger, Jos I. M.; Verhoeven, Ludo – Journal of Autism and Developmental Disorders, 2014
The present study examined whether individuals with autism spectrum disorder (ASD) are able to update and monitor working memory representations of visual input, and whether performance is influenced by stimulus and task complexity. 15 high-functioning adults with ASD and 15 controls were asked to allocate either elements of abstract figures or…

Bowler, Dermot M.; Gaigg, Sebastian B.; Gardiner, John M. – Journal of Autism and Developmental Disorders, 2014
Diminished episodic memory and diminished use of semantic information to aid recall by individuals with autism spectrum disorder (ASD) are both thought to result from diminished relational binding of elements of complex stimuli. To test this hypothesis, we asked high-functioning adults with ASD and typical comparison participants to study grids in…

de Vries, Marieke; Geurts, Hilde M. – Journal of Autism and Developmental Disorders, 2012
Children with autism spectrum disorders (ASDs) show daily cognitive flexibility deficits, but laboratory data are unconvincing. The current study aimed to bridge this gap. Thirty-one children with ASD (8-12 years) and 31 age- and IQ-matched typically developing children performed a gender emotion switch task. Unannounced switches and complex…

Reed, Phil; Gibson, Evelyn – Journal of Autism and Developmental Disorders, 2005
Stimulus over-selectivity is a phenomenon displayed by individuals with autism, and has been implicated as a basis for many autistic-spectrum symptoms. In four experiments, non-autistic adult participants were required to learn a simple discrimination using picture cards, and then were tested for the emergence of stimulus over-selectivity, both…
