As a way to examine the nature of age-related differences in lineup identification accuracy, young (16-33 years) and older (60-82 years) witnesses viewed two similar videotaped incidents, one involving a young perpetrator and the other involving an older perpetrator. The incidents were followed by two separate lineups, one for the younger perpetrator and one for the older perpetrator. When the ...

Judges in the United States, the United Kingdom, and Canada have ruled that witnesses may not wear the niqab—a type of face veil—when testifying, in part because they believed that it was necessary to see a person’s face to detect deception (Muhammad v. Enterprise Rent-A-Car, 2006; R. v. N. S., 2010; The Queen v. D(R), 2013). In two studies, we used conventional research methods and safeguards ...

Experimental studies of how juries reach their verdicts in court strongly suggest that coherence reasoning is ubiquitous in judicial reasoning. Under massive cognitive pressure to process large numbers of conflicting pieces of evidence and witness reports, jury members base their judgment on an assessment of the most coherent account of the events. From a normative perspective, the legitimacy o...

A theft staged for 80 unsuspecting eyewitnesses was followed by a picture lineup that did or did not contain the thief. In an attempt to see if eyewitness confidence is tractable after the identification, half of the eyewitnesses who identified the thief (accurate witnesses) and half who identified an innocent suspect (inaccurate witnesses) were briefed by a "prosecutor" who suggested they rehe...

A theft was staged 70 times for pairs of eyewitnesses (N = 140) who then made a photo-lineup identification. Witnesses then received 1 of 9 types of information regarding the alleged identification decision of their co-witness. Witnesses told that their co-witness identified the same person whom they had identified showed an increase in the confidence they expressed to a confederate police offi...

This article argues that an iconic event in the history of helping research -- the story of the 38 witnesses who remained inactive during the murder of Kitty Genovese -- is not supported by the available evidence. Using archive material, the authors show that there is no evidence for the presence of 38 witnesses, or that witnesses observed the murder, or that witnesses remained inactive. Drawin...

The study evaluated the usefulness of repeat-interviewing of witnesses to crimes who were intoxicated by alcohol at the time of the incident and their first interview, and then re-interviewed when not intoxicated the following day. Sixty young, social drinkers were divided into three groups. One group was given a “placebo” (alcohol-like) beverage, a second was given a “low dose” of alcohol (0.2...

A new generation of expert witnesses in sexual and reproductive health is needed, including those in nursing as well as medical roles. Being an expert witness is a significant commitment alongside clinical work. Nevertheless, the work is stimulating and rewarding. Training is essential before starting medicolegal work. In particular expert witnesses need to be able to apply appropriate legal te...
