Abstract
Saccades made to outline drawings of eccentric forms were compared with saccades made to single-point targets. Saccades could be directed to designated locations within eccentric forms nearly as accurately and precisely as they could be directed to single points. Saccades directed to the form as a whole landed at consistent locations near the center of the form. These results show that contour information is sufficient for accurate computation of a saccadic command and that this computation is constrained by the internal coding of the shape. A serial two-stage process, voluntary selection followed by a weighted-averaging process, is proposed for computation of the saccadic command based on information provided by shape.Keywords
