These differences, referred to as a "detectability gradient," have been attributed to target detection accomplished by a serial processing mechanisma scan. The mathematical model of such a mechanism, developed in the previous report, is equally applicable to a series of attentional shifts or to a perceptual, i.e., a preattentive, mechanism. The present experiments were designed to test the hypothesis that this scan is attentional in nature. The results provide additional evidence for the scanning hypothesis but do not support the view that this scan represents a series of attentional shifts. @ 1990 Academic Press, Inc.
