A team of researchers at UWA have evaluated the assertion that individuals with Autism, and those showing high, non-clinical levels on the Autism Quotient (AQ), demonstrate poorer processing of global elements of a scene. Our work has investigated processing of texture and also contours where global integration is a demonstrated substrate.

A series of psychophysical experiments will be presented testing participants either clinically diagnosed with Autism or scoring high on the AQ, and control groups of low AQ scorers. The embedded Figures Test (EFT) provides a baseline for prior claims of deficient global processing. All Autism groups demonstrated the expected superiority with the EFT. The subsequent work has been aimed at trying to understand the process underpinning the visual performances differences.
