DETECTION AND IDENTIFICATION OF GEOMETRIC FORMS USING PERIPHERAL AND CENTRAL VIEWING

Two tasks. using identical geometric forms. compared nasal peripheral. temporal peripheral. and central viewing. In the first task. using a yes-no confidence rating scale procedure, four Ss judged the presence or absence of a known geometric form (detection). In the second task. the same Ss judged which of several know forms was presented (identification). The major result is that nasal and temporal peripheral viewing are similar and that both peripheral regions differ from central viewing. Also, detection and identification are relatively independent processes; the ease of detection of a form does not predict the ease of identification of that form. © 1969 Psychonomic Society, Inc.
