[Perceptual set and selective information processing (author's transl)].
Four experiments investigated the perceptual set effect due to prior presentation of response alternatives in tachistoscopic recognition task. The experiments using two alternatives showed significant set effect when (a) no masking stimulus (Experiment I), and (b) the masking stimulus of random-dot was given (Experiment II). (c) In Exp. II the greater effect was found, under the higher masking energy. (d) Under patterned mask condition the results showed no significant effect (Experiment III). However, (e) even under patterned mask condition significant effect was found, if one alternative was provided (Experiment IV). These results were considered to indicate that the set enhanced the degree of figure-ground segregation.
