The human body is capable of adapting its movements to the environment in a magnificent way. In order to do that, the information from the environment needs to be picked up and acted on, and the body needs to be coordinated to respond properly. If one takes into account all the muscles and neurons that are making sure that one can lift a cup without dropping it or squeezing it, this is quite an impressive job. Hester Knol is interested in understanding how the human body adapts to changes in the environment. This incorporates the control of movements, the adaptation to visual and mechanical perturbations, the coupling between perception and action, and the integration of information. This interest has resulted in studies on the adaptation to mechanical perturbations during walking, and the influence of visual information (e.g. visual illusions) on pointing movements.
The research in the Applied Cognitive Psychology group will mainly focus on the adaptation rates in reaching movements.
