Embedded Figures Detection in Autism and Typical Development: Preliminary Evidence of a Double Dissociation in Relationships with Visual Search
Jarrold, Christopher; Gilchrist, Iain D.; Bender, Alison
Developmental Science, v8 n4 p344-351 Jul 2005
Individuals with autism show relatively strong performance on tasks that require them to identify the constituent parts of a visual stimulus. This is assumed to be the result of a bias towards processing the local elements in a display that follows from a weakened ability to integrate information at the global level. The results of the current study showed that, among children with autism, ability to locate a figure embedded in a larger stimulus was only related to performance on visual search trials where the target was identified by a unique perceptual feature. In contrast, control children's embedded figures performance was specifically related to their performance on visual search trials where the target was defined by a conjunction of features. This double dissociation suggests that enhanced performance on perceptual tasks by children with autism is not simply a consequence of a quantitative difference in ability to engage in global processing.
