| Abstract: | C. G. Penney (1980) reported that serial recall of a list containing both auditorily and visually presented verbal items produced a lower level of recall than did separate recall of auditory and visual items. This finding was interpreted as support for the hypothesis that auditory and visual items are processed in separate streams in short-term memory, and that it is difficult to integrate these 2 streams into 1 sequence for rehearsal. The present study tested an alternate interpretation of the earlier results, the hypothesis that retention of order information is facilitated by S's being able to organize the list into 2 short sequences rather than 1 long sequence. Three experiments (72 university students) were carried out in which spatial location or category of stimulus material (letters or digits) was used to establish 2 types of items. Total recall from a list did not differ significantly between the serial and category recall conditions. Results rule out the organizational interpretation of the bisensory experiment and, therefore, provide indirect support for the separate streams hypothesis.
