Two experiments tested mnemonics for enhancing memory for family meeting occurrences and details. Experiment 1 tested a set of seven mnemonics to facilitate recollections of family meeting occurrences. Mnemonics helped respondents report 70% more event occurrences than were reported during unaided free recall. Experiment 2 tested (i) a revised set of mnemonics to facilitate recollections of family meeting occurrences and (ii) a version of the cognitive interview to facilitate recollections of event details. Similar to Experiment 1, the revised set of mnemonics helped respondents recall double the number of events recalled during unaided free recall. For event details, when compared with a control interview, the cognitive interview elicited more than twice as many person, conversation, action, and setting details. The mnemonics used in these experiments are relatively easy to modify and implement in intelligence-gathering interviews with human intelligence sources.

Laboratory research and field research have reliably shown that the cognitive interview (CI) enhances eyewitness recall in comparison with standard interview protocols in a criminal investigation context. To address some of the major criticisms of the existing CI literature, the current experiment compared the CI with the Federal Law Enforcement Training Center's five-step interview protocol in an intelligence-gathering context using experienced interviewers and adult interviewees. The CI elicited significantly more event-relevant information from the interviewees than the five-step model, the standard training offered at Federal Law Enforcement Training Center.

Taking an immediate recall test prior to misinformation exposure can increase eyewitness suggestibility-a finding termed retrieval-enhanced suggestibility. Here, we examined whether retrieval-enhanced suggestibility would occur when participants were administered an immediate Cognitive Interview (CI). The CI is an investigative interviewing technique that consistently elicits more correct details in memory reports than standard interviews. In this study, participants watched a video of a crime and then completed a distractor task (control condition), a free recall test, or the CI. They then heard misinformation presented in a narrative. Participants produced more accurate memory details in the CI than in free recall despite spending equal time on both tasks. However, the CI also increased the later report of misinformation relative to the control condition. These results show that initial retrieval can increase subsequent suggestibility even when such retrieval occurs under relatively ideal conditions. Copyright © 2013 John Wiley & Sons, Ltd.
