Relations between children's overestimation of their physical abilities and accident proneness.

Two experiments examined developmental changes in the accuracy of children's judgments about their physical abilities. Experiment 1 showed that 6- and 8-year-olds overestimated their ability to perform tasks just beyond and well beyond their ability. Adults only had difficulty making judgments about tasks just beyond their ability. Experiment 2 investigated how experience with performing activities influences judgments about physical abilities. Six-year-olds again overestimated their ability to perform tasks just beyond and well beyond their ability. Eight-year-olds were more accurate about tasks well beyond than just beyond their ability. In both experiments, overestimation of ability was associated with accidental injuries for 6- but not for 8-year-olds. The discussion focuses on children's overestimation of physical abilities and the relation between overestimation and accident proneness.
