“Intuitive” Lie Detection of Children’s Deception by Law Enforcement Officials and University Students

Adults ability to detect childrens deception was examined. Police officers, customs officers, and university students attempted to differentiate between children who lied or told the truth about a transgression. When children were simply questioned about the event (Experiment 1), the adult groups could not distinguish between lie-tellers and truth-tellers. However, participants were more accurate when the children had participated in moral reasoning tasks (Experiment 2) or promised to tell the truth (Experiment 3) before being interviewed. Additional exposure to the children did not affect accuracy (Experiment 4). Customs officers were more certain about their judgments than other groups, but no more accurate. Overall, adults have a limited ability to identify childrens deception, regardless of their experience with lie detection.     

The Effect of Intellectual Disability on Children's Recall of an Event Across Different Question Types

This research examined the performance of 80 children aged 9-12 years with either a mild and moderate intellectual disability when recalling an innocuous event that was staged in their school. The children actively participated in a 30-min magic show, which included 21 specific target items. The first interview (held 3 days after the magic show) provided false and true biasing information about these 21 items. The second interview (held the following day) was designed to elicit the children's recall of the target details using the least number of specific prompts possible. The children's performance was compared with that of 2 control groups; a group of mainstream children matched for mental age and a group of mainstream children matched for chronological age. Overall, this study showed that children with either a mild or moderate intellectual disability can provide accurate and highly specific event-related information. However, their recall is less complete and less clear in response to free-narrative prompts and less accurate in response to specific questions when compared to both the mainstream age-matched groups. The implications of the findings for legal professionals and researchers are discussed.     

‘Any friend of yours is a friend of mine’: investigating the utilization of an interpreter in an investigative interview

Premised on a body of literature suggesting target-interviewer rapport is a critical component of successful interviews, we explored the effect of two interpreter-related variables – the physical placement of the interpreter in the room, and the nature of the relationship between the interpreter and the target – on target-interviewer rapport. A total of 125 bilingual (Spanish/English) participants viewed a mock crime video and were then interviewed, via an interpreter (or not). Interpreters either built rapport with the participant immediately prior to the interview or did not, and were either seated beside the interviewer or behind the target, commensurate with recommendations from training manuals. When the interpreter and target engaged in a short rapport-building session prior to an investigative interview, the target rated their interaction with the interviewer less negatively compared to when rapport building did not occur. Furthermore, when the interpreter sat behind the target, the target viewed the interaction more negatively than when the interpreter sat beside the interviewer (triangular configuration). These findings suggest ways in which interpreters can be utilized more effectively, especially in terms of seating configuration, rapport development between a target and interpreter, and importantly, the potential for that target-interpreter rapport to transfer to the target-interviewer relationship.
