The subject of this research is the deprivation of freedom at two time points. A total of 490 convicts from open, semi-open, and closed prisons participated in the research. Freedom deprivation intensity was determined by using the freedom deprivation scale (α = .93). The results of the research indicate that almost all the participants reported freedom deprivation. The prison type had an impact on freedom deprivation intensity, whereas an influence of the ward type on deprivation was not demonstrated. Freedom deprivation intensity was consistent from the turn of the century to the present day.

Mentally disordered individuals are increasingly coming into contact with the police. The current study explored investigative interview practice with mentally disordered suspects to examine how they respond and the impact this has on the level of information obtained. Transcripts of interviews conducted with vulnerable and nonvulnerable suspects (N = 66) were analysed using a specially designed coding framework. Results highlighted that best practice is generally not being adhered to regarding questioning techniques (for example, the use of open questions). Furthermore, although police officers altered their communication to suit the needs of the vulnerable suspect, they were also more likely to use minimisation tactics. Mentally disordered suspects sought more clarification for open questions and provided more information to closed questions. They also demonstrated higher levels of vulnerability (suggestibility and compliance) when compared with their nonvulnerable counterparts. Implications regarding interviewing methods for this vulnerable group are discussed.

Verbal lie detection tools are almost exclusively examined in Western Europe and North America, but practitioners worldwide show interest in such tools. Because cultural differences in the efficacy of such tools may occur, it is important to examine their efficacy in different cultures. In this article, we focus on proportion of complications, which in previous research was more diagnostic than “total details” in two British samples and in three samples that each included Hispanic, Russian, and South Korean participants. In the present article, we merged the three non-British samples and analysed the data by presenting them for each cultural group separately. Truth tellers disclosed the details of a trip away they had made, whereas liars fabricated such details. Proportion of complications discriminated truth tellers from liars in all three groups and was consistently a better indicator of veracity than total details. Implications of the findings are discussed.

The present study aimed to examine the demographic information of sex offenders in South Korea and explore whether a U.K. thematic model of criminal behaviour could be replicated in the Korean context. The 27 variables of crime scene actions derived from 50 Korean sexual offences through a content analysis were analysed with smallest space analysis. Chi-square was also administered to explore the differences in offender characteristics among behavioural themes. Consequently, three separate action themes, hostility–involvement, theft, and control, were revealed. Next, each case was assigned to one of the dominant or hybrid themes, with 84% of the total cases being classified to the dominant themes. Moreover, there were significant differences in four offender characteristics between the themes: “previous conviction of robbery,” “previous conviction of sexual crime,” “knowing the victim,” and “vehicle use.” These outcomes have implications for the development of the Korean profiling system.

The Cognitive Interview is a memory-enhancing interview protocol designed to optimise the access and retrieval of eyewitness memories. Its Mental Reinstatement of Context (MRC) component requires interviewees to mentally reconstruct the crime event they witnessed. Individual differences in mental time travel (MTT) relate to the extent to which a person mentally re-experiences personal events from his or her past. Individual differences in MTT have been found to predict correct recall of a simulated crime event under immediate MRC recall conditions. To explore the relationship between MTT and performance under MRC conditions further, the present study presented a simulated crime video to 30 police officers and 26 members of the public. Eyewitness recall was tested under MRC conditions either immediately or 1 week later. Participants' general MTT and also MTT relating specifically to the crime video itself were measured via self-report. Less correct information and more confabulations were produced after 1 week, but delay had no effect on the amount of incorrect information reported. No difference in recall was found between police officers and members of the public. Better quality MTT relating to the crime video was found to be a positive predictor of the amount of information correctly recalled under immediate conditions but not after 1 week. General MTT scores did not predict correct recall under either delay condition. Interviewers need to be aware that, due to individual differences, some witnesses may perform better under the MRC component than others.

The purpose of the study was to examine the effectiveness of the micro-expressions training tool (METT) in identifying and using micro-expressions to improve lie detection. Participants (n = 90) were randomly assigned to receive training in micro-expressions recognition, a bogus control training, or no training. All participants made veracity judgements of five randomly selected videos of targets providing deceptive or truthful statements. With the use of the Bayesian analyses, we found that the METT group did not outperform those in the bogus training and no training groups. Further, overall accuracy was slightly below chance. Implications of these results are discussed.

Despite a large body of research investigating the effects of age and gender on eyewitness suggestibility, the majority of studies has focussed on the impressionability of participants when attempting to recall the presence of items from an event. Very little research has attempted to investigate the effects of age and gender on the suggestibility of eyewitnesses when attempting to attribute blame. Participants (N = 268) viewed and discussed a crime (video) with cowitnesses before giving individual statements. Confederates were used to expose the participants to misinformation during the discussion, suggesting that the wrong bystander was responsible for the offence. Findings indicated that participants who encountered the misinformation were more likely to make a false blame attribution and were more confident in their erroneous judgements. The results found no significant age- or gender-related differences in blame conformity rates; however, male eyewitnesses showed greater levels of overconfidence in their false responses than female participants, after encountering cowitness misinformation.

Although a great deal of research has focussed on and continues to focus on fraud prevention and detection, there is still no reliable way to predict who will become a white-collar criminal/fraudster. Significant benefits would result if and when this can be done. This paper recognizes that there are many common characteristics that exist among fraudsters and investigates whether fraud can be predicted based on the psychological, sociological, and environmental state of children throughout their upbringing. Research shows that children with a negative childhood develop negative habits, emotions, and mentalities, including disorders that can linger well into their adult lives. These negative characteristics can ruin relationships and possibly even influence an individual to commit fraud. This paper provides initial evidence regarding the potential significance of some childhood characteristics that may contribute to the likelihood that someone will become a white-collar criminal. Given that no other similar research exists, this paper may help guide future researchers who are also attempting to solve this complex problem.
