DETECTION OF AN AMBIGUOUS VISUAL SIGNAL WHILE IMAGING.

Abstract

The experiments reported used a simple discrimination task as a baseline, against which to compare the effects of discrimination and imaging. In all the experiments, imaging plus discrimination and discrimination tasks differed significantly in d', regardless of order of presentation, nature of the stimuli, information and familiarity with the stimuli. The d' scores for imaging tasks under several conditions were .74, 1.36, 1.61, 1.77, 1.94, and 2.03; for comparable discrimination tasks, d' scores were 2.19, 2.68, and 2.71. Response bias (Lx) was also generally higher for imaging, indicating a more conservative criterion. (Author)
