THE PREDICTION OF COLLISIONS: PRELIMINARY CONSIDERATIONS

Three studies were made to predict whether or not two moving stimuli would collide. In all experiments, one stimulus (central stimulus) moved upward along a straight path and the other (peripheral stimulus) moved from right to left along a straight path. The first experiment studied the effect of (a) the position at which the peripheral stimulus became visible, (b) passing distance when the stimuli did not collide, and (c) velocity of the stimuli. The second experiment studied the ability of ss to predict such collisions when the peripheral stimulus was visible only intermittently (1, 2 or 5 250-msec observations versus continuous observation). The final study investigated whether the moment the prediction was made depends on mutual distances between stimuli per se or on angle of regard. /TRRL/
