EFFECTS OF DIFFERENTIAL VALUE AND EXPOSURE TIME UPON THE DETECTION AND MEMORY OF SYMBOLS IN A VISUAL SEARCH TASK

Abstract

The accuracy of reporting data from briefly-ex posed, multi-target symbolic displays in which the value or importance of the targets varies within the display was shown to vary inversely with the differential ratio of value of the tar gets. The data also suggested that (1) an in crease in differential ratio does not facilitate the reporting of more important targets, but rather decreases reports of less important ones, (2) the difference in accuracy of report to high and low valued targets varies directly with exposure time up to 2.5 sec for the display used with 1.5 sec as a possible optimum. The results are consistent with the hypothesis that differential value produces a selective recall from short-term memory storage.
