The current work at the perception action lab based in Queen's University Belfast, is focused on how we may harness the link between perception and action to provide cues and guides for individuals with atypical motor control. This talk will outline results from recent work completed with children diagnosed with Autism Spectrum Disorder (ASD) and adults with Parkinson's disease (PD). Firstly the results from an initial, exploratory, comparative study using the Movement Assessment Battery for Children (M-ABC2), to investigate the true area of motor impairment in children with ASD will be presented. Based on these initial findings, results from a controlled, reach-grasp interceptive task will be discussed. A clear distinction in levels of performance will be highlighted between children with ASD and adults with PD indicating variation in the ability to use perceptual, sensory information to spatially and temporally guide action.
