Motion integration is anisotropic during smooth pursuit eye movements

<div>Four movies showing of how motion coherence depends on the direction of smooth pursuit eye movements. We used a multiple-aperture array, with drift speeds being attributed to correspond to (100% coherence) to a single global motion direction or randomly to some proportion.</div><div><br></div><div>Participant's task is to track the black dot and discriminate between upward or downward motion of the surrounding. All movies show global motion that is a slightly downward from horizontal. The elements are low contrast(necessary for motion to cohere) and therefore may only be visible in full screen mode or close to the screen.<b></b><i></i><u></u><sub></sub><sup></sup><br></div><div><b></b><i></i><u></u><sub></sub><sup></sup><br></div><div>Movie 1: Global motion (50% coherent) opposite to the motion of the pursuit target (black dot)</div><div><br><div> </div></div><div><div>Movie 2: Global motion (100% coherent) opposite to the motion of the pursuit target (black dot)</div><div> </div><div><br></div><div><div>Movie 3: Global motion (50% coherent) in the direction of the pursuit target (black dot)</div><div> </div><b></b><i></i><u></u><sub></sub><sup></sup><br></div><div><div>Movie 4: Global motion (100% coherent) in the direction of the the pursuit target (black dot)</div><div><br></div></div></div>
