The Credibility of Children's Testimony: Can Children Control the Accuracy of Their Memory Reports?

Abstract

In previous work with adults (A. Koriat & M. Goldsmith, 1994, 1996c), it was shown that people can enhance the accuracy of their testimony substantially when they (a) are effective in monitoring the correctness of their answers, (b) are free to control their reporting accordingly (i.e., to decide which pieces of information to volunteer and which to withhold), and (c) are given incentives for accurate reporting. A theoretical model was developed, which specifies the critical role of metacognitive monitoring and control processes in mediating free-report memory accuracy. The present study applies that model to examine the strategic regulation of memory accuracy by children. Three experiments indicate that both younger (ages 7 to 9) and older (ages 10 to 12) children can enhance the accuracy of their testimony by screening out wrong answers under free-report conditions but suggest a developmental trend in the level of memory accuracy that is thereby achieved. The implications of the results for the dependability of children's testimony in legal settings are discussed.
