Description

Presented By:

Dr Susan Morris & Yi Huey Lim (PhD candidate)

Abstract:

Unusual visual behaviour reported in individuals with autism spectrum disorder (ASD) may reflect anomalies in visual perception. The magnocellular pathway within the visual system develops very early in life and as such may be susceptible to subsequent visual and brain developmental abnormalities. Assessment of visual motion processing can improve existing knowledge concerning magnocellular processing in ASD; however, evidence in this area is not conclusive. Therefore, the purpose of this project is to discover how individuals with ASD process visual motion. This current project takes on a methodological approach not used in the current ASD literature, which is to examine the impact of visual field stimulation on visual motion processing in individuals with ASD in an immersive virtual reality environment. The findings of this project may inform management and intervention strategies for individuals with ASD exhibiting unusual visual behaviours. Additionally, the findings may contribute to the development of early differential diagnostic tools for individuals with ASD.

About the Presenters:

Dr Susan Morris is an academic with a passion for reducing disability in people with autism. Her research team from the Curtin Autism Research Group and Telethon Kids are at the cutting edge of autism research. The working hypothesis for the group is that autism is a “normal” response to an atypical perceptual experience. Dr Morris, PhD student Yi Huey Lim and their team are using immersive visualization to adjust unconscious perception in people with and without autism. Their findings are revealing an altered perceptual world that may explain many of the behavioural differences we see in people with autism. Armed with this knowledge, Dr Morris and the team plan to develop biological markers for early diagnosis; and therapeutic strategies and tools to reduce disability for those on the autism spectrum.

Yi Huey Lim is a PhD candidate from School of Occupational Therapy and Social Work, Curtin University. She is currently working with individuals with autism spectrum disorder to understand how they process and make sense of visual information in a changing environment.
