This study investigated the degree of realism in the confidence judgments of 41 girls and 40 boys (aged 11-12 years old) of their answers to 41 two- alternative event memory questions relating to a short film clip showing two men kidnap a woman at a bus stop. Four different confidence scales were used, a numeric scale, a picture scale, a line scale and a verbal 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, both boys and girls overestimated the total number of memory questions they had answered correctly compared with the number of questions they in fact had answered correctly. Moreover, the boys gave higher estimates compared with the girls. In brief, the results indicate that, at least in the context investigated, children's confidence in and estimations of their own event memory showed poor realism (overconfidence and overestimation). A comparison with previous research on grown-ups suggest that that children show poorer realism than grown-ups.
