The exposure time and the time between successive exposures were varied in a picture recognition task. Exposure times of .2, .5, 1.0, 2.0, and 4.0 sec. were orthogonally combined with between-slide durations of 1.0, 2.0, and 4.0 sec. Confidence ratings of recognition increased monotonically with exposure time but were not affected by the amount of time between slides. These results suggest there is no direct analog of verbal rehearsal in the processing of complex visual information. Complex pictures appear to be processed almost entirely during the period in which they are physically exposed.
