Abstract
The effects of differential ratio of value, exposure time, and number of categories upon the detection and report of letters were investigated in a visual search task. The differential ratios of value of the letters were 21, 4:1, 8:1, and 16:1, the exposure times of the stimulus slides were 0.5, 1.5, and 2.5 sec.; and the numbers of categories on a slide were 4,6,8,10, and 12 letters. The results indicated that Ss made more correct identifications, initial responses, and false reports of higher value symbols than of lesser value. Further, the percentage of correct identifications and percentage of initial responses of higher value symbols varied with exposure time and ratio. These effects were attributed to selective recall from short-term memory storage.Keywords
