- This study investigated the degree of realism in the confidence judgments of 11-12 year old children (N=81) 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. The results indicate that, at least in the context investigated, 11-12 year-old children’s confidence in their event memory show poor realism. A comparison with previous research on adults indicates that children show noticeably poorer realism.

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

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.

Hot cognition in investigative judgments: The differential influence of anger and sadness
- 2007

Ingår i: Law and Human Behavior. ; 31:6, s. 537-551
-
Tidskriftsartikel (refereegranskat)abstract
- The authors predicted that the cognitive appraisal tendencies associated with sadness and anger would exert different influences on investigators’ crime-related judgments. Supporting evidence was found in an experiment with 61 experienced criminal investigators. First, when judging the reliability of a witness statement, sad participants relied on their perception of both witness and situational variables, whereas angry participants relied only on their perception of witness variables. This corresponds to the emphasis placed on situational and individual control in the appraisals associated with sadness and anger, respectively. Second, when making judgments of the case, sad participants were sensitive to the consistency of a witness statement with the central hypothesis of the investigation, indicating substantive processing, whereas angry participants were unaffected by statement-hypothesis consistency, indicating heuristic processing. The findings suggest that the process of reliability assessment can be better understood by consulting theories of attribution and information processing.

Motivational bias in criminal investigators’ judgments of witness reliability

Tidskriftsartikel (refereegranskat)abstract
- An experiment was conducted where experienced criminal investigators (N = 49) evaluated the testimony of a witness who either confirmed or disconfirmed the focal hypothesis in a homicide case. Participants’ motivation to perpetuate the hypothesis was manipulated by varying the need for cognitive closure via time pressure. The hypothesis-inconsistent witness was perceived as less reliable and credible, although its background and witnessing conditions were identical to those of the hypothesis-consistent witness. While this asymmetrical skepticism was not moderated by time pressure, participants under high (vs. low) time pressure were less inclined to adjust their confidence in the hypothesis in line with the witness testimony. Discussion focuses on implications for criminal investigations and theoretical contributions to investigative psychology
