This study investigated that deception about an eye-witnessed crime leads to memory distortion when participants deceive different targets. Previous study has showed that deception about the crime leads memory distortion and there were two deceptive strategies: Commission strategy and Omission strategy (Christianson & Bylin, 1999). In Tanaka (2005) has showed that Omission strategy inhibited memory rehearsal and leads to memory distortion. There are many factors in deception in addition to deceptive strategy, for example, targets of deception, quantity of deception. In this study, we hypothesize that memory performances are differ by lie targets because past study showed that memory performance of eyewitnesses were differ by subjects in a crime (Yuille & Cutshal, 1986). So we examine that memory performances after deception are differ by targets of deception in the crime event.
