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

Famous quotes containing the words smooth, pursuit and/or attention:
“We were soon in the smooth water of the Quakish Lake,... and we had our first, but a partial view of Ktaadn, its summit veiled in clouds, like a dark isthmus in that quarter, connecting the heavens with the earth.”
—Henry David Thoreau (1817–1862)
“This mania of the mothers of the period, to be constantly in pursuit of a son-in-law.”
—Stendhal [Marie Henri Beyle] (1783–1842)
““The unities, sir,’ he said, “are a completeness—a kind of universal dovetailedness with regard to place and time—a sort of general oneness, if I may be allowed to use so strong an expression. I take those to be the dramatic unities, so far as I have been enabled to bestow attention upon them, and I have read much upon the subject, and thought much.””
—Charles Dickens (1812–1870)
