Assessing the detectability of motorbikes in peripheral vision and the role of head movements.

This study investigates "looked-but-failed-to-see" errors by measuring detection performance of motorcycles vs. other vehicles at high eccentricities. Specifically, it is testing whether there is a difference in the detectability of different vehicle types at high eccentricities and explores mechanisms by which this difference may occur. First this tests whether an under rotation of the head can explain any difference. Secondly, it tests whether the boundary between monocular and binocular vision may contribute to this difference. Thirdly, this experiment tests whether there are differences in peripheral detectability between vehicle types.
