Recognition of self-generated actions from kinematic displays of drawing

Five experiments addressed the question of whether individuals can distingu ish between self-generated and other-generated actions when seeing their vi sual effects. Each experiment consisted of a recording session in which par ticipants drew familiar and unfamiliar characters without receiving visual feedback and a recognition session in which they provided self-or-other jud gments (SOJs) to indicate whether a kinematic display reproduced the visual effects of their own actions. The main results were that self-generated an d other-generated drawing can be distinguished, that the familiarity of cha racter shapes does not influence the accuracy of SOJs, and that velocity in formation is crucial for the identification of self-generated drawing. The ability to determine authorship from kinematic displays of drawing provides evidence for the contribution of action-planning structures to perception.
