Front-facing biological motion perception (BMP) tasks. The connecting black lines and the balls are used here as a visual aid and were not presented during the experiment. (A) The task consists of choosing whether an animated point-light walker is walking rightward or leftward from the subjects own vertical reference. In short, the task is to determine whether the walker’s predicted path will end up to the left or the right of the subject’s own vertical center of reference. (B) The task consists of choosing whether an animated point-light soccer player is kicking a ball to the right or to the left of the subject’s own vertical center of reference.
