Elsner, C., Falck-Ytter, T., & Gredebäck, G. (2012) Humans anticipate the goal of other people’s point-light actions. Frontiers in Psychology, 3, 120

This eye tracking study investigated the degree to which biological motion information from manual point-light displays provides sufficient information to elicit anticipatory eye move- ments. We compared gaze performance of adults observing a biological motion point-light display of a hand reaching for a goal object or a non-biological version of the same event. Par- ticipants anticipated the goal of the point-light action in the biological motion condition but not in a non-biological control condition. The present study demonstrates that kinematic information from biological motion can be used to anticipate the goal of other people’s point-light actions and that the presence of biological motion is sufficient for anticipation to occur.
