We believe the decisions we make result from careful thought processes. Yet our body is needed for turning these decisions into actions. Can it be that our motor system is also driving the decisions we make? The researchers will investigate to what extent the effort to move influences perceptual decision-making. In a series of behavioural experiments, they will systematically explore whether required muscle force, reaching distance, and handedness lead to a bias in selected choices. This approach may ultimately lead to a paradigm shift in cognitive psychology regarding the factors that contribute to decision-making behaviour in health and pathology.
