The recall of a five-consonant sequence was tested after retention intervals of 0, 2, 4 and 6 sec. Each subject was tested only once, thus eliminating intra-experimental PI. Two experimental conditions were employed. In one (W) both the stimulus and interpolated material were presented visually. In the VA condition presentation of the stimulus was visual with auditory presentation of the interpolated material. Significant forgetting occurred in both conditions, VA recall being superior to W. The implications of these results for a unitary theory of memory are discussed.
