Children's evaluation of sources of information about traits

Children's assessment of the value of different sources of information about psychological traits was investigated among 6- to 7-year-olds and 10- to 11-year-olds across 5 studies (N = 330). Older children were more likely than younger children to reject self-report as a source of information about the highly evaluative traits smart and honest, but no such age-related difference was seen for the less evaluative comparison traits outgoing and nervous. A similar pattern of age-related differences was seen when children were asked to identify which of 4 sources of information--self-report, teacher report, peer report, or direct observation--would be most useful for obtaining information about the evaluative and comparison traits. The age-related increase in skepticism about self-report as a source of information for evaluative traits was associated with an increased appreciation of the role that social desirability plays in self-presentational processes.
