Advantage for emotional words in immediate and delayed memory tasks: could it be explained in terms of processing capacity?
Emotional stimuli are better remembered and recognized than neutral ones. This advantage for emotional stimuli has been repeatedly obtained when testing long-term retention. However, there are contradictory results concerning retention of emotional information when short retention intervals are used. The aim of the present study was, on the one hand, to test the effect of retention interval on memory for emotional stimuli (Experiment 1). The results showed that emotional information is better remembered than neutral information in both immediate and delayed memory tests, suggesting that the advantage for emotional information is not limited to long retention intervals. On the other hand, I tried to test the proposals made by Christianson and Nilsson (1984) and Bower (1992). These authors suggested that the advantage for emotional stimuli could be explained as emotional stimuli spending more processing capacity during acquisition, thus rendering less capacity available to encode simultaneously presented information (Experiments 2 and 3). Results showed that concurrent presentation of emotional stimuli did not inhibit the recall of neutral stimuli. These findings do not seem to support the proposals of Christianson and Nilsson (1984) and Bower (1992). According to these results, some mechanisms other than a greater spending of processing capacity have to be involved in the advantage for emotional information in memory.
