This study investigates how children negotiate social norms with peers. In Study 1, 48 pairs of 3- and 5-year-olds (N = 96) and in Study 2, 48 pairs of 5- and 7-year-olds (N = 96) were presented with sorting tasks with conflicting instructions (one child by color, the other by shape) or identical instructions. Three-year-olds differed from older…

This study investigated the development of all 3 components of episodic memory (EM), as defined by Tulving, namely, core factual content, spatial context, and temporal context. To this end, a novel, ecologically valid test was administered to 109 participants aged 4-16 years. Results showed that each EM component develops at a different rate.…

This study examined how children's play varied as function of child's sex, play partner's sex, and whether they played in dyads or groups. Observation data revealed that boys' same-sex play was more active-forceful, farther from presence of adults, and more stereotyped than girls', a pattern exaggerated in groups. Mixed-sex play was more likely…

Examines research in folkbiology (commonsense understandings of plants and animals) to argue that several lines of comparative research are needed to understand the acquisition of folkbiology in particular and conceptual development in general. Asserts that comparisons are needed between children and adults within a given society, between adult…

Examined role of social-referential context in 13- and 18- month-olds' mapping of verbal and nonverbal symbols to object categories.

Two studies examined individual differences in 7- to 10-year-olds' contextual facilitation. Findings indicated that poor readers showed more contextual facilitation than good readers but the relative context benefit was greater for good readers. Comprehension was a better predictor of contextual facilitation that decoding. Dyslexics showed greater…

Surveyed fourth-, seventh-, and tenth-graders in Japan and the United States regarding evaluations of peer group exclusion of atypical peers.

Girls were less willing to…

This study examined cultural differences and similarities in socialization during free play and a waiting task among Japanese mothers and their preschoolers temporarily residing in the United States and U.S. mothers and their preschoolers. Findings suggest an emphasis on autonomy among U.S. dyads and an emphasis on relatedness among Japanese…

Investigated age and context differences in children's judgments about excluding peers from group activities on the basis of gender and race. Found that the vast majority of children rejected exclusion in contexts in which only stereotypes justified exclusion. Older children (13 years) were more likely to allow exclusion than younger (7 and 10…

Compared Chinese and Canadian 7-, 9-, and 11-year-olds' moral evaluations of lie- and truth-telling in stories involving pro- and antisocial behavior. Found that Chinese children rated truth-telling less positively and lie-telling more positively in prosocial settings than Canadians. Both rated truth-telling positively and lie-telling negatively…

Observed home interaction between parents and 2- and 4-year-olds at Time 1 and 2 years later. Found that parent mental state talk to children varied by child's age, context of talk, and parent gender. Four-year-olds with older siblings produced and heard more cognitive talk and less desire talk than children without older siblings. Time 1 family…
