20 Ss performed a dichotic listening task with simultaneous pairs of spoken digits given under different conditions of pair numbers (3, 4, 5 & 6 pairs) and presentation rates (4, 3, 2, 1 & 1/2 pairs per sec), while his attention was restricted to one of the two ears (attended ear). The recall level of unattended ear was more affected by the pair number conditions than by the presentation rates. Number of recalled items in all conditions was nearly constant 5.5 items for both ears combined. The results were discussed in favor of an interpretation based on an attentional processing in the short-term memory. Ear superiority effect under the attention controlled situation was also obtained.
