Abstract

The effect of emotion on true and false memories using DRM paradigm was investigated in two experiments with old-new recognition test(experiment 1) and with source identification task(experiment 2). In 8 lists which were presented in the study phase, half of the list items consisted of words associated with emotionally charged critical lures and the rest of them were with non-emotional critical lures. In experiment 1, participants were asked to recognize if each of the presenting 160 stimuli contained 8 critical lure items(not presented in the study phase) and list items was old or new during recognition test. In experiment 2, participants were asked to identify and determine correctly each source of the presenting 160 stimuli included 8 critical lure items and 80 list items in the source identification test. In recognition test, Emotional valence had positive effects on true recognition. There was no-emotion related difference between emotional lure items and non-emotional lure items in false recognition. On the contrary, in source identification test, source memory about emotional list items was observed at higher level than neutral list items. However, the performance of source identification about emotional lure items were poorer than neutral lure items, which implies that false memory on emotional lures occurred more than on neutral lures during source identification. The results in two experiments suggested that emotional valence facilitated the extent of the activation and had positive effects on true memories. On the contrary, emotion affects to false memories with the various way across retrieval context. The theoretical implications of these results are discussed.
