Recognition memory for valenced and arousing materials under conditions of divided attention

Two experiments are reported that examined the effect of both valence and arousal on recognition memory performance. Each experiment used two classes of negative items that differed in arousal, as well as a neutral and non-arousing set of items. In Experiment 1 a difficult divided attention task was crossed with the learning and test phases of the experiment. In Experiment 2 encoding time was manipulated and remember-know judgements were collected. The emotional enhancement effect often found with verbal materials survived the depletion of cognitive resources, as did the extra benefit accruing from high arousal. Although we found that arousal led to more recollection, the general conclusion that we draw is that the effect of emotion on recognition memory can be attributed to relatively automatic influences.
