This article empirically tests a previously developed theoretical framework for mathematics identity based on students' beliefs. The study employs data from more than 9,000 college calculus students across the United States to build a robust structural equation model. While it is generally thought that students' beliefs about their own competence…

Three studies investigate the role of competence factors (defined as acquisition of Piagetian formal reasoning) and performance factors (defined as influences from content and expectations) with respect to adolescents' reasoning about advertisements reporting product tests. (Author/MP)

Three experiments in which photo or video presentations could guide one's search for a hidden object showed that under certain circumstances even 24-month-olds displayed representational insight. The first two experiments replicated earlier findings of chance performance across 4 trials, with 24-month-olds performing above chance in 3 of 4…

Results indicate that the performance factors examined do, in part, account for subjects' difficulties on standard Piagetian horizontality and verticality tasks but that they cannot fully account for the overall sex differences. (RH)

Maintains that authors' meta-analytic findings make early competence accounts of theory of mind increasingly unlikely. Asserts that findings argue against executive function expression accounts, including that advocated by Scholl and Leslie (PS532407). Explains that meta-analytic findings directly contradict Scholl and Leslie's predictions…

This study explored 5- to 17-year-olds' use, self report, and awareness of verbal problem-solving strategies and strategy effectiveness. Findings indicated that children's verbal strategies moved from overt, to partially covert, to fully covert forms with age. Self-reports of strategy use were accurate yet incomplete. Strategy awareness was low…
