Eye-movements and search-time of four subjects were studied as they searched for a target-dial in a 4 x 4 array of dials which were differentiated either by 1 color, 2 shape, 3 a combination of color and shape, or 4 were uncoded. Search-time varied reliably between conditions it was generally shortest in the color-condition, followed by color-shape, shape, and the uncoded condition. Subjects were capable of using both shape and color simultaneously. Search-time appeared to be strongly associated with the average number of fixations required for target-detection but not with other measures of eye- movements. Other characteristics are also noted.
