Smooth Pursuit and Spatial Attention
Various lines of research suggests a tight coupling for closed loop pursuit and spatial attention. For instance, during the close loop phase selective attention is coupled to the pursuit target such that untracked targets which move in the same direction with the target are poorly processed by the visual system. Recently, a loose coupling of open loop pursuit and attention was suggested, when there is only one possible moving target. This difference between pursuit and saccades may be accounted for by the differences in latency. Pursuit eye movements are initiated within 90-150 ms, while typical latencies for voluntary saccades are in the order of 200-250 ms
