Abstract
Compared retention of visually and of auditorily presented trigrams (CCC) by 18 undergraduates using the Peterson distractor technique. In contrast to previous experiments, retention of visually presented trigrams was superior, particularly at the longer retention intervals, e.g., 18 sec. These results extend recent evidence that the retention of visually presented displays of symbols and of auditorily presented sequences of symbols can be mediated by different memories that are largely independent of each other. That memory for visually presented stimuli is less disrupted by the interpolated task (counting backward) than is memory for auditory presented stimuli follows from the hypothesized independence of the 2 memory systems.
