Various aspects of moral functioning, aggression, and positive peer regard were assessed in 153 preschool children. Our hypotheses were inspired by an evolutionary approach to morality that construes moral norms as tools of the social elite. Accordingly, children were also rated for social dominance and strategies for its attainment. We predicted…

The purpose of this study was to assess whether understanding relational terminology (i.e., "more, less," and "fewer") mediates the effects of intervention on compare word problems. Second-grade classrooms (N = 31) were randomly assigned to one of three conditions: researcher-designed word-problem intervention, researcher-designed calculation…

The self-teaching hypothesis proposes that orthographic learning takes place via phonological decoding in meaningful texts, that is, in context. Context is proposed to be important in learning to read, especially when decoding is only partial. However, little research has directly explored this hypothesis. The current study looked at the effect of…

A controversial issue in bilingual research is whether in the early stages of L2 learning, access to the conceptual system involves mediation of L1 lexical representations [Kroll, J. F., & Stewart, E. (1994). Category interference in translation and picture naming: Evidence for asymmetric connections between bilingual memory representations.…

Preschool children who did not group a set of geometric stimuli according to complete similarity on a pretest were taught classification wither in a modeling or in a reinforcement condition. Modeling was found to be an effective means of teaching classification behavior. (ST)

Examined development of multiplication skills in 8- to 12-year-olds taught by discovery methods. Found a general shift away from less effective strategies across ages 8 to 12, but by 11 years, relatively few used the most effective strategy of retrieval for all operands. Effective strategy development was related to nonverbal reasoning ability and…

Studies five-year-olds' relative number judgements of small and large number displays with and without perceptual aids. Children were found to respond to local rather than global density differences and to benefit from the provision of perceptual aids on both small and large number displays. (Author/AS)

Ten- to thirteen-year-old children selected either the objectively more effective keyword method or the naturalistic context method for learning vocabulary meanings. Concludes that, even in the absence of explicit performance feedback, children can be induced to reflect on their use of strategies and their outcomes on subsequent cognitive actions.…
