In the current experiment we tested to what extent we process the motion information from the tracked objects. Specifically, we were interested, whether Multiple Object Tracking (MOT) display can affect sensitivity to motion, which is in the direction of either targets or distractors. We presented MOT task with 3 targets and 6 distractors, followed with RDM for 500 ms. The subjects were asked about the targets and the direction in RDM. We confined direction of the tracked objects, at each moment only 3 directions were allowed, making sum of motion vectors constant. We measured the threshold for coherence in RDM for conditions: 1) motion parallel with recent motion of the targets, 2) motion different from the motion of the targets, 3) different motion of the targets. We found decreased sensitivity in the second condition, suggesting that we preferentially process the direction information from the attended objects.
