[en] This study examined the influence of emotional valence on the production of DRM false memories (Roediger & McDermott, 1995). Participants were presented with neutral, positive or negative DRM lists for a later recognition (Experiment 1) or recall (Experiment 2) test. In both experiments, confidence and recollective experience (i.e., “Remember-Know” judgements; Tulving, 1985) were also assessed. Results consistently showed that, compared with neutral lists, affective lists induced more false recognition and recall of non presented critical lures. Moreover, although confidence ratings did not differ between the false remembering from the different kinds of lists, “Remember” responses were more often associated with negative than positive and neutral false remembering of the critical lures. In contrast, positive false remembering of the critical lures was more often associated with “Know” responses. These results are discussed in light of the Paradoxical Negative Emotion (PNE) hypothesis (Porter et al., 2008).
