Eye-Movements During Search for Coded and Uncoded Targets

Abstract

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.
