Mnemonic Techniques and Lie Detection: Accuracy of Truth and Deception Judgments in Repeated Accounts

This study was an examination into whether the use of memory-enhancing techniques (mnemonics) in interviews can be helpful to distinguish truth tellers from liars. In previous (Izotovas et al., 2018), it found that when mnemonic were used interview immediately after event, truth-tellers reported more details than liars those immediate and again a delay. Moreover, truth-tellers, but not liars, showed patterns reporting indicative genuine memory decay.
 current experiment, participants (n = 92) asked read repeated statements by Izotovas al.’s (2018) decide they truthful or deceptive. One group (informed condition) received information about findings before reading statement. The other no statement (uninformed condition). After made veracity judgements, open-ended question asking what factors influenced their credibility decision. Although judged accurately informed condition (65.2%) uninformed (47.8%), this difference significant. both conditions deceptive detected at chance level (52.2%). Participants who relied on self-reported diagnostic verbal cues deceit accurate unreliable cues. could happen because only minority (27.4%) based decisions truth/deceit.
