Abstract : The purpose of the present experiment was to determine how accurately observers could recognize complex stimuli, either colored crosshatched forms or three-digit numbers. The general procedure was that used by Shepard and Teghtsoonian (J. exp. Psychol., 1961, 62, 302309) where Ss went through a deck of cards con taining the stimuli and judged whether or not they had seen each particular card before. Each specific stimulus item (i.e., form or number) occurred twice in a deck with anywhere from 0 to 15 other stimuli intervening between successive presentations. There were significantly more false positives with figures than with numbers, but otherwise the two types of stimuli were recognized with about equal accuracy. Thus, it would appear that under these conditions the recognition of numbers is somewhat more accurate than the recognition of colored, cross-hatched forms. (Author)
