The notion that cognitive processes ”leak” into motor output of decisions inspired much recent process-tracingresearch. In mouse-tracking, an increasingly popular decision-making paradigm, difficult choices lead to increased curvatureof the mouse trajectories towards the unchosen option. Here we explore whether traces of a decision process can be found inits motor output in a more naturalistic setting. Our subjects performed a series of choices between a smaller reward now and alarger reward at some delay. Using Kinect camera, we recorded subjects’ walking trajectories when they moved towards theirpreferred option displayed in one of the corners across the room. We found that deviation of subjects’ trajectories from theideal trajectory increased with delay when they preferred the ”later” option, and decreased with delay in trials where the ”now”option was chosen. Our results suggest that walking trajectory of a person can provide information about their ongoing thoughtprocesses.
