Helping to sort the liars from the truth-tellers: The gradual revelation of information during investigative interviewsDando, Coral J.; Bull, Ray; Ormerod, Thomas C.; Sandham, Alexandra L.; University of Wolverhampton; University of Derby; Lancaster University; Department of Psychology; University of Wolverhampton; UK; School of Law and Criminology; Derby University; UK; Department of Psychology; Lancaster University; UK; et al. (Wiley, 2013-04-20)Research examining detection of verbal deception reveals that lay observers generally perform at chance. Yet, in the criminal justice system, laypersons that have not undergone specialist investigative training are frequently called upon to make veracity judgements (e.g., solicitors; magistrates; juries). We sought to improve performance by manipulating the timing of information revelation during investigative interviews. A total of 151 participants played an interactive computer game as either a truth-teller or a deceiver, and were interviewed afterwards. Game information known to the interviewer was revealed either early, at the end of the interview, or gradually throughout. Subsequently, 30 laypersons individually viewed a random selection of interviews (five deceivers and five truth-tellers from each condition), and made veracity and confidence judgements. Veracity judgements were most accurate in the gradual condition, p < .001, η2 = .97 (above chance), and observers were more confident in those judgements, p < .001, η2 = .99. Deceptive interviewees reported the gradual interviews to be the most cognitively demanding, p < .001; η2 = .24. Our findings suggest that the detection of verbal deception by non-expert observers can be enhanced by employing interview techniques that maximize deceivers' cognitive load, while allowing truth-tellers the opportunity to respond to evidence incrementally.
Perceptions of psychological coercion and human trafficking in the West Midlands of England: Beginning to know the unknownDando, Coral J.; Walsh, Dave; Brierley, Robin; University of Derby (Public Library of Science, 2016-05-05)Modern slavery is less overt than historical state-sanctioned slavery because psychological abuse is typically used to recruit and then control victims. The recent UK Draft Modern Slavery Bill, and current UK government anti-slavery strategy relies heavily on a shared understanding and public cooperation to tackle this crime. Yet, UK research investigating public understanding of modern slavery is elusive. We report community survey data from 682 residents of the Midlands of England, where modern slavery is known to occur, concerning their understanding of nonphysical coercion and human trafficking (one particular form of modern slavery). Analysis of quantitative data and themed categorization of qualitative data revealed a mismatch between theoretical frameworks and understanding of psychological coercion, and misconceptions concerning the nature of human trafficking. Many respondents did not understand psychological coercion, believed that human trafficking did not affect them, and confused trafficking with immigration. The public are one of the most influential interest groups, but only if well informed and motivated towards positive action. Our findings suggest the need for strategically targeted public knowledge exchange concerning this crime.
