Design/methodology/approach -A detailed account is given of the interaction between practitioner and witness for producing a facial composite. This account involves an overview of the Cognitive Interview (CI) and the Holistic CI (H-CI) techniques used to obtain a description of the face of an offender (target); we then describe how this information is used to produce a composite from five popular face-production systems: Sketch, PRO-fit, E-FIT, EvoFIT and EFIT-V. An online annex is also made available to provide procedural information for additional composite systems.
Practical implications -The work is valuable to forensic practitioners and researchers as a reference for interviewing techniques (involving a CI or an H-CI) and using facial-composite systems.Originality/value -We provide an accessible, current guide for how to administer interviewing techniques and how to construct composites from a range of face-production systems.

Older adults’ memory reports are often less complete and accurate than those by younger adults. The current study assessed the suitability of the Self-Administered Interview (SAI) as retrieval support for older eyewitnesses, and examines whether experience with the SAI leads to improved performance on subsequent events where the SAI is not used. Participants recalled an event with the SAI or free recall instructions. After 1 week, all participants watched a second event and freely recalled its content. SAI participants reported more correct details for the initial event, and a “transfer” of the initial recall advantage to the second event was observed.
RationaleResearch has shown that alcohol can have both detrimental and facilitating effects on memory: intoxication can lead to poor memory for information encoded after alcohol consumption (anterograde amnesia) and may improve memory for information encoded before consumption (retrograde facilitation). This study examined whether alcohol consumed after witnessing a crime can render individuals less vulnerable to misleading post-event information (misinformation).MethodParticipants watched a simulated crime video. Thereafter, one third of participants expected and received alcohol (alcohol group), one third did not expect but received alcohol (reverse placebo), and one third did not expect nor receive alcohol (control). After alcohol consumption, participants were exposed to misinformation embedded in a written narrative about the crime. The following day, participants completed a cued-recall questionnaire about the event.ResultsControl participants were more likely to report misinformation compared to the alcohol and reverse placebo group.ConclusionThe findings suggest that we may oversimplify the effect alcohol has on suggestibility and that sometimes alcohol can have beneficial effects on eyewitness memory by protecting against misleading post-event information.
Recent studies have explored ways to increase cognitive load in liars to identify cues to deception. This study used a driving simulator as a load-inducing technique to explore differences between truth-tellers and liars during an investigative interview scenario and also investigated the effect of rehearsing lies in this context. Deception affected driving performance. Truthtellers drove more slowly compared with their own baseline, whereas unrehearsed liars sped up. There was no difference in speed between truth-tellers and rehearsed liars. In addition, truth-tellers had significantly faster reaction times compared with their own baseline, than both rehearsed and unrehearsed liars. During the interviews, truth-tellers provided significantly more visual and auditory details and mentioned significantly fewer cognitive operations than liars. The findings add to the body of literature exploring the optimal relationship between cognitive load and secondary task performance to identify cues to deception. Copyright
Nonbelieved memories (NBMs) are vivid memories that people no longer believe represent events that happened. This study examined NBMs across the adult life span. Participants (N ϭ 138, ages 18 -72) described a nonbelieved memory, why they stopped believing the memory, dated the memory, and rated the memory on metacognitive and recollective features. Participants also rated age-matched believed memories and believed-not-remembered events (e.g., family stories). While the NBMs were dated across the life span, the majority were dated in mid-to-late childhood (ages 4 -12), indicating that autobiographical belief for memories from this period is vulnerable to revision later in life. Commensurate with prior findings, believed and nonbelieved memories shared similar recollective qualities, and NBMs were rated as less important and less coherent. This pattern did not differ as a function of age, time since the event, or time since withdrawal of belief. NBMs remain vivid for long periods of time once formed.
Few studies have examined the impact of alcohol on metacognition for witnessed events. We used a 2 × 2 balanced placebo design, where mock witnesses expected and drank alcohol, did not expect but drank alcohol, did not expect nor drank alcohol, or expected but did not drink alcohol. Participants watched a mock crime in a bar-lab, followed by free recall and a cued-recall test with or without the option to reply "don't know" (DK). Intoxicated mock witnesses' free recall was less complete but not less accurate. During cued-recall, alcohol led to lower accuracy, and reverse placebo participants gave more erroneous and fewer correct responses. Permitting and clarifying DK responses was associated with fewer errors and more correct responses for sober individuals; and intoxicated witnesses were less likely to opt out of erroneous responding to unanswerable questions. Our findings highlight the practical and theoretical importance of examining pharmacological effects of alcohol and expectancies in real-life settings.
Limited verbal abilities might act as a barrier to witnesses with Intellectual Disabilities (ID) to provide accurate testimony. This might be particularly problematic when the police need to create a facial composite image. Contrary to featural composite systems such as Electronic Facial Identification Technique (E-FIT), holistic systems such as Evolutionary Facial Identification Technique (EvoFIT) do not require the witness to provide a verbal description of a perpetrator's face. Instead, they rely more on face recognition, which may make them more suitable for people with ID. The current study compared the performance of people with and without ID at creating composites using E-FIT and EvoFIT. Although ID composites created with EvoFIT were more often accurately identified than E-FIT composites, the performance of ID participants was overall very poor across both systems and considerably poorer than that of non-ID participants. The implications of these findings for practitioners working in the Criminal Justice System are discussed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
