Rehearsal of visual and auditory stimuli while shadowing.

Abstract
Presented memory trigrams to 24 undergraduates using 1 of 3 methods: visual-concurrent (all 3 letters appeared simultaneously), visual-successive, and auditory-successive. During the 12-sec retention interval, Ss shadowed and reported their rehearsals and mnemonic associations via switches. On trials without associations, recall performance supported the hypothesis that the form of rehearsal is related to presentation modality. However, the frequency and temporal patterning of the rehearsals over the retention interval were virtually identical for all 3 presentation conditions, suggesting that the "control processes" were relatively independent of both method of presentation and modality of rehearsal. Data suggest that the efficiency of each rehearsal was also independent of those same factors, in each case quite comparable to that of a concurrent visual stimulus.
