In order to investigate an interaction between auditory and visual memory, a serialrecall experiment was conducted. Ten random digits were presented, auditorily, visually and audio-visually at rapid (0.8sec.) and slow (2.4sec.) rates. The peculiarity of the serialposition curve on each modality was summarized as follows: (1) The performance at a primacy portion under a visual presentation was better than that under an auditory one. The primacy portion under an audio-visual presentation at rapid and slow rates was consistent with that under the auditory and the visual presentation, respectively. (2) At both rapid and slow rates, little recency effect appeared under the visual presentation, whereas a great recency effect appeared under the auditory one as well as the audio-visual one. It was concluded that (1) the primacy effect under audio-visual presentation at rapid and slow rates results from the auditory memory and the visual one, respectively; and (2) the recency effect under audio-visual presentation at both rates results from the auditory memory.
