We are pursuing 3 main research themes in the Developmental Visuomotor Neuroscience Lab. The goal of Theme 1 is advance the understanding of visuomotor integration during the performance of skillful movements in 3D space. The overarching hypothesis for this work is that binocular vision provides an essential input for the development and optimal performance of manipulation skills, which is based on predictive control mechanisms that require the knowledge of object properties. Experimental work includes studies with visually-normal children and adults, as well as people with abnormal binocular vision. Results from this work will help us develop assessment tools and training regimens to improve visuomotor coordination.
Research in Theme 2 focuses on evaluating gaze behavior in pilots with different levels of expertise. The goal is to determine how gaze behaviour changes as a function of learning, and to use this information to develop predictive models of pilot competency. This research is conducted using eye tracking in a flight simulator with a team of scientists in the Aviation Research Cluster. Results will be used to advance and innovate aviation training by informing a competency based education model for pilot skill assessment.
The goal of Theme 3 is to develop more sensitive and objective behavioral tests to improve concussion diagnosis and recovery monitoring following a sport-related head injury. Objective and sensitive screening measures for concussions are important in order to reduce the long-term consequences associated with repetitive head injury, such as early onset brain and behavior disorders
