Development of perception in action in healthy and at-risk children

Devising effective assessment techniques and therapy for movement disorders in young children requires in-depth measures of the child's perceptuo-motor functioning. It is argued that the field of movement disorders can benefit from an ecological approach to perception and action, where perception subserves action and action influences perception. Three notions central to the ecological approach are described and illustrated with our recent research on infant and child perceptual and motor behaviour.
