Human Perceptual-Motor Control, Vision and Action, Perceptual-Motor Compatibility, Coordination
The general theme of my research program is the study of perceptual and sensory contributions to the preparation and execution of goal-directed movement. The areas of investigation include:
(a) vision and action investigation of the interaction between parallel visual pathways for visual perception and action, and the utilization of vision during goal-directed action
(b) movement preparation electrophysiological investigations of the preparation of goal-directed action and of response selection processes
(c) perceptual-motor compatibility investigation of the impact of stimulus-response organization on human information processing and performance
(d) perceptual-motor behaviour in Down syndrome elaboration of a model of cerebral specialization and motor function in persons with Down syndrome that has, as its primary feature, the dissociation of the functional subsystems serving speech perception and the organization of complex movement
(e) coordination dynamics the examination of cognitive, neuromuscular, and biomechanical constraints that influence the dynamics of movement coordination.
