Following this line, the main purpose of the present study was to further investigate lack of rehearsal as the best explanation for the memory-undermining effect of simulating amnesia. We replicated the standard procedure to study feigning amnesia effects (e.g., van Oorsouw and Merckelbach, 2004) by using the same mock crime video employed by Mangiulli et al. (unpublished) instead of a narrative mock crime story (e.g., Bylin and Christianson, 2002; Sun et al., 2009). We showed participants a video clip pertaining to a violent crime and asked them to either feign amnesia (simulators group) or confess the crime (confessors group) during the first memory phase. We also included a delayed test-only control group consisting of participants who did not receive any instruction. After 1 week, we requested all three groups to genuinely report all the information they could remember about the offense. We expected that simulators would recollect fewer correct details of the crime than confessors (hypothesis 1). However, we anticipated that both confessors and simulators would perform better than the delayed-test only control group (hypothesis 2). Finally, we predicted simulators to report more distortion and commission errors (i.e., introduction of new information) than confessors on the subsequent memory recall (hypothesis 3 and 4, respectively).
