[The role of velocity in the anticipation of visual movement].

Summary The role of the velocity of visual movement is studied in a task of prediction of motion where the subject must predict when a presently invisible moving object will intercept some target. When the visible motion consists in intermittent appearances of the moving object, the response do not vary systematically with their number of appearances. However, a continuously visible motion gives an algebraic error of prediction lower than an intermittent one. We found that prediction is later when visible motion space is longer and that this prediction is more later when velocity is higher. We present an attempt to explain the results according to a possible strategy used by the subjects in which some estimation of the visible velocity is included.
