  • Deception among pairs: "Let's say we had lunch and hope they will swallow it!"
  • 2003
  • Ingår i: Psychology, Crime and Law. - Taylor & Francis. ; 9:2, s. 109-124
  • Tidskriftsartikel (refereegranskat)abstract
    • Deception research has neglected the fact that legal-workers often have to try to detect deceit on the basis of statements derived from pairs of suspects, each having been interrogated repeatedly. To remedy this shortcoming we conducted a study where each member of 10 truth-telling pairs and 10 lying pairs was interrogated twice about an alibi. One hundred and twenty undergraduate students were enrolled as lie-catchers. The main findings were that (a) overall deception detection accuracy was modest; (b) lie-catchers given access to a large number of statements did not outperform lie-catchers given access to a lesser number of statements; (c) when asked to justify their veracity assessments the most frequently reported cue was 'consistency within pairs of suspects'; (d) all cues to deception were of low diagnostic value. Psycho-legal aspects of integrating sequential information in deception detection contexts are discussed.

  • Child witnesses’ metamemory realism
  • 2006
  • Ingår i: Scandinavian Journal of Psychology. - Blackwell Publishing. - 1467-9450 .- 0036-5564. ; 47:6, s. 461-470
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigated the degree of realism in the confidence judgments of 11 to 12-year-olds (41 girls and 40 boys) of their answers to questions relating to a short film clip showing a kidnapping event. Four different confidence scales were used: a numeric scale, a picture scale, a line scale and a written scale. The results demonstrated that the children showed a high level of overconfidence in their memories. However, no significant differences between the four confidence scales were found. Weak gender differences were found in that the girls were slightly, but significantly, better calibrated than the boys. In addition, although both boys and girls overestimated the total number of memory questions they had answered correctly, the boys gave higher estimates compared with the girls. In brief, the results indicate that, at least in the context investigated, 11-12 year-old children's confidence in and estimations of their own event memory show poor realism (overconfidence and overestimation). A comparison with previous research on adults indicates that 11 to 12-year-old children show noticeably poorer realism.

  • Does mood influence the realism of confidence judgments?
  • 2002
  • Ingår i: Scandinavian Journal of Psychology. - 0036-5564. ; 43:3, s. 253-260
  • Tidskriftsartikel (refereegranskat)abstract
    • In this study we investigated how mood influences the degree of realism in participants’ confidence judgments (based on an episodic memory task). Using music and film in combination, we successfully induced half of the participants into an elated mood, but failed to induce a sad mood in the other half. Contrary to our prediction, our data indicated that there was no difference in the realism of the confidence between the conditions. When relating this result to previous research our conclusion is that there is no, or very little, influence of mood of moderate intensity on the realism of confidence judgments.

  • The effects of source and type of feedback on child witnesses' metamemory accuracy
  • 2005
  • Ingår i: Applied Cognitive Psychology. - 0888-4080. ; 19:3, s. 331-344
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigated the effect of feedback on the accuracy (realism) of 12-year-old children’s metacognitive judgments of their answers to questions about a film clip. Two types of judgments were investigated: confidence judgments (on each question) and frequency judgments (i.e., estimates of overall accuracy). The source of feedback, whether it was presented as provided by a teacher or a peer child, did not influence metacognitive accuracy. Four types of feedback were given depending on whether the participant’s answer was correct and depending on whether the feed­back confirmed or disconfirmed the child’s answer. The children showed large over­confidence when they received confirmatory feedback but much less so when they received disconfirmatory feedback. The children gave frequency judgments implying that they had more correct questions than they actually had. No main gender differences were found for any of the measures. The results indicate a high degree of malleability in children’s metacognitive judgments.
