Subjects were required to categorize verbally the figures presented tachistoscopically with an increasing amount of the exposure duration, 2 through 3000ms. The figures were all ambiguous in that they had response multiplicity. With the increase of duration, the number of cognitive responses increased to a certain point, but, in some figures, it tended to decrease as the duration increased further. This suggested the existence of some conflict in the categorization process as well as the presence of some reorganization in the processing of the sensory information. The number of response categories as an index of response multiplicity and the subject's rating of confidence in cognitive response as an index of S-R compatibility were also examined.
