Porter’s research investigates how humans learn/re-learn motor skills, and how the human nervous system controls the body to generate skillful movements. He investigates how factors such as practice schedule design, skill level, motor/cognitive impairments, cognitive load, decision making, human factors, instruction/feedback, and focusing of attention interact with motor skill learning and performance. He is an active member of the North American Society for the Psychology of Sport and Physical Activity (NASPSPA), and the National Strength and Conditioning Association (NSCA). He is also an Associate Editor for the scientific journal Frontiers in Movement Science and Sport Psychology, and he is an editorial board member for the Journal of Motor Learning and Development and the International Journal of Motor Control and Learning.
