Variable length consonant stimuli in a “Peterson & Peterson” short-term memory paradigm

The effects of stimulus length, interpolated task interval, and rehearsal upon recall in a “Peterson & Peterson” short-term memory paradigm were tested. All three main effects, but none of the interactions attained significance. The superiority of self-initiated as opposed to E-paced rehearsal was suggested as was the increased necessity for any type of rehearsal as stimulus length increased.
