Preschoolers Use Trait-Relevant Information to Evaluate the Appropriateness of an Aggressive Response.

The tendency for 3- to 5-year-old children to use trait-relevant information about other people when evaluating aggressive responses to ambiguous behavior was examined across two studies (N = 81). Children were more likely to endorse the use of aggression against a "mean" versus a "nice" story character. Additionally, they were more likely to endorse the use of aggression against a story character who feels happy rather than sad when bad things happen to other kids. These findings suggest that, as early as preschool, trait-relevant information about other people can serve as a tool with which children evaluate the appropriateness of aggression in response to ambiguous behavior. Moreover, these findings provide evidence that even before the onset of formal schooling, trait and mental state information can influence social judgments.

Gender and Psychological Essentialism.

When individuals reason in an essentialist way about social categories, they assume that group differences reflect inherently different natures (Gelman, 2003; Rothbart & Taylor, 1992). This paper describes the psychological and social implications of essentialist beliefs, and examines the extent to which children exhibit psychological essentialism when reasoning about gender. The authors discuss reasons young children as well as older children show essentialist reasoning in some contexts, but not in others. Finally, the authors suggest directions for future research, and discuss a primary challenge to many working in this field: reduction of rigid gender beliefs.

Young children's beliefs about the relationship between gender and aggressive behavior.

Young children's beliefs about the relationship between gender and aggression were examined across 3 studies (N=121). In Study 1, preschoolers (ages 3 to 5) described relational aggression as the most common form of aggression among girls and physical aggression as the most common form among boys. In Study 2, preschoolers and a comparison group of 7- to 8-year-olds were likely to infer that relationally aggressive characters are female and physically aggressive characters are male. Study 3 revealed that preschoolers show systematic memory distortions when recalling stories that conflict with these gender schemas. These findings suggest that even before children reach school age, they have organized patterns of beliefs about gender that affect the way they process social information.

When to Cry Over Spilled Milk: Young Children's Use of Category Information to Guide Inferences About Ambiguous Behavior.

Three studies (N = 171) examined preschool children's tendency to use category information to make inferences about ambiguous behavior. Children heard stories in which category information about story characters was manipulated and behavioral information was held constant. Participants were asked to evaluate, explain, and determine the significance of the behavior in question. Children tended to be harsher judges of the same ambiguous behaviors when performed by (a) humans as compared to animals, (b) boys compared to girls, and (c) older children compared to younger children. Results suggest that young children hold differentiated notions of the mental states and dispositions that underlie behavior and that these notions vary as a function of category membership. These findings support the conclusion that even young children can hold and use multiple folk psychologies.

Valence Effects in Reasoning About Evaluative Traits.

Reasoning about evaluative traits was investigated among a group of 7- and 8-year-olds (N = 34), a group of 11- to 13-year olds (N = 25), and a group of adults (N = 23) to determine whether their inferences would be sensitive to the valence of social and academic traits. Four aspects of trait-relevant beliefs were examined: (1) malleability, (2) stability over time, (3) origin in terms of nature versus nurture, and (4) an inference criterion that concerns how readily traits are inferred. Although there was evidence of an age-related decrease in the tendency to emphasize positive information, participants of all ages responded that positive traits are less malleable and more stable over time than negative traits, that the positive influences of biological and environmental factors are likely to override the negative influences, and that competence can be more readily inferred from positive outcomes than from negative outcomes.

Source monitoring reduces the suggestibility of preschool children.

The relation between source monitoring and suggestibility was examined among preschool children. Thirty-two 3- to 5-year-olds were simultaneously presented with a brief story in two different modalities, as a silent video vignette and a spoken narrative. Each modality presented unique information about the story, but the information in the two versions was mutually compatible. The children were then asked a series of questions, including questions about the source (modality) of story details, and leading questions about story details (to assess suggestibility). Performance on the source-monitoring questions was highly correlated with the ability to resist suggestion. In addition, children who were asked source-monitoring questions prior to leading questioning were less susceptible to suggestion than were those who were asked the leading questions first. This study provides evidence that source monitoring can play a causal role in reducing the suggestibility of preschool children.

Preschool children's reasoning about ability.

Young children's reasoning about ability was investigated among 155 preschoolers (M = 4 years, 10 months) across 3 studies. Results suggest that preschoolers are sensitive to mental state information when making judgments about another child's ability: They judged a child who finds a task easy to be smarter than one who finds the same task hard. Systematic patterns of errors on recall tasks suggest that preschoolers perceive positive correlations between (a) exerting effort and experiencing academic success, and (b) being nice and having high academic ability. Results from a comparison group of forty 9- to 10-year-olds (M = 9 years, 10 months) suggest that the preschool findings generally reflect emerging patterns of reasoning about ability that persist into later childhood, but that the perceived correlations between high effort and academic outcomes and between social and academic traits diminish with age.
