The research carried out during the period of the grant continued several lines of investigation on the way in which sensory and high-level influences contribute to the control of smooth and saccadic eye movements and on the perceptual implications of eye movements. We 1 provided the first clear evidence that symbolic cues determine the direction of anticipatory smooth eye movements, showing that adaptive models, based on algorithms that modify pursuit according to prior performance cannot work 2 showed that saccades to spatially-extended targets are best understood by a serial model, with a selection stage followed by a spatial pooling mechanism 3 showed that slow control is a velocity, not a position, corrective and 4 showed that saccades not shifts of attention are required for accurate perception of poorly- segregating textures. These results are all consistent with the view that sensory and cognitive influences combine at a relatively high level of processing to provide a single, coherent input to the oculomotor system. Kowler also edited a book, published by Elsevier, containing major reviews and theoretical treatments of eye movements, vision and cognition.
