Yves Lajoie is an associate professor in the School of Human Kinetics. He obtained his Ph.D. in motor control and learning from the Laval University in 1994. In 1995, he realized one year of post-doc in physiotherapy at McGill University where he received a fellowship from the Center of Excellence in Neurosciences. In 1995, he joined Laurentian University as an assistant professor. Since 1996, he has been carrying out externally funded research (NSERC) in the area of cognitive involvement, static and dynamic equilibrium and aging. He is a member of the "Society for Neurosciences" and of the "North American Society for Psychology of Sports and Physical Education".
- Motor control, Psychomotricity
My research currently deals with postural and attention control. The literature shows that when we pay less attention to controlling our actions, they often improve. We have shown that posture also benefits from this attentional strategy, among young adults and even seniors. At this time, we are trying to see if we can extrapolate these results to other population groups (normal or pathological).
