  • Eyewitnesses under influence: How feedback affect the realism in confidence
  • 2006
  • Ingår i: Psychology, Crime & Law. - : Informa UK Limited. ; 12:1, s. 25-38
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigated the effect of two types of feedback (confirmatory and disconfirmatory) on the accuracy in witness’ confidence judgements of their event memory. Overall the witnesses evidenced overconfidence both when they received feedback and in the control condition (no feedback). The results showed that confirmatory feedback caused higher overconfidence, compared both with when receiving disconfirmatory and no feedback. The results suggest that the impact of feedback on the accuracy of confidence judgments show the same pattern of results for event memory as for line-up identification tasks. Finally, when witnesses rated the total number of questions that they had answered correctly they gave fairly correct estimates compared with their actual number of correct answers.

  • The effects of source and type of feedback on child witnesses' metamemory accuracy
  • 2005
  • Ingår i: Applied Cognitive Psychology. - : Wiley. - 0888-4080 .- 1099-0720. ; 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 answers 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.

  • Effects of investigators’ epistemic motivation: Biased perception and sensitivity to criminal evidence
  • 2005
  • Ingår i: The 2nd meeting of the NNPL, Kristianstad, Sweden, September 29-30.
  • Konferensbidrag (refereegranskat)abstract
    • External pressures in investigators’ work environment, such as time pressure, occupational culture, and pressure from media and the public, are likely to activate epistemic goals—subjective preferences regarding the outcome of cognitive tasks. Predictions were derived from the motivated social cognition framework as to how epistemic goals might influence the tasks carried out in criminal investigations. A first study examined the prediction that investigators’ initial hypothesis regarding a crime would influence their interpretation of ambiguous criminal evidence, particularly when motivated to achieve cognitive closure. The results of two experiments, with 50 experienced criminal investigators (Experiment 1) and 68 university students (Experiment 2), showed that students’ interpretations of a criminal case material differed significantly as a function of their initial hypothesis. In contrast, investigators tended to perceive the material in incriminating terms across conditions. A non-significant trend suggested that investigators with a high (vs. low) need for cognitive closure (NFC) were more influenced by their initial hypothesis. A second study tested the prediction that witnesses who reported information inconsistent (vs. consistent) with investigators’ initial hypothesis would be perceived as less reliable and credible, particularly by investigators working under high NFC. The prediction received consistent support in the data from 49 experienced criminal investigators. Although the effect was not moderated by investigators’ level of NFC, participants high (vs. low) in NFC were more persistent in their initial hypothesis regarding the crime, and less influenced by the witness evidence.
