What children say about classroom performance: sex and grade differences in perceived competence.

Naturalistic observations and interviews with children in kindergarten, first, second, and fourth grades (ages 5 1/2-10 years) were used to examine sex and age differences in evaluations of, and attributions to performance of, self and others. Observers coded the content of peer verbal exchanges during class work times, and the children were subsequently interviewed about their and their peers' classroom performance, as well as expectancies of performance on a novel task. Analyses of classroom observations generally supported previous laboratory findings; positive evaluation declined with grade level, and more negative self-evaluations and attributions were made by girls than by boys. In contrast, the interview measures did not show grade or sex differences in self-assessment; however, the consistency across interview and observation measures was greater at higher grade levels and for boys than for girls. Previous interpretations of age and sex differences in performance assessment are reexamined, and the possible impact of social context on evaluative statements is discussed.
