The Influence of Gender Categories and Gender Stereotypes on Young Children's Generalizations of Biological and Behavioral Characteristics.

We examined the influence of categorization and stereotyping on young children's (N = 96; 39 to 71 months of age) use of gender to make generalizations regarding novel biological and behavioral characteristics. Participants were asked to sort pictures of children according to either gender, common gender stereotypes, or shirt color. Then participants performed a triad inductive reasoning task.

Mother-Child Conversation and Children's Social Understanding During Middle Childhood.

The authors investigated the relationship between mother-child conversation and children's social understanding during middle childhood. Thirty-eight mother-child pairs participated, including a younger group (5-7 years old) and an older group (8-10 years old). Children completed 2 measures of social understanding and mothers and children discussed 4 stories involving social dilemmas.

Children's and adults' judgments of the certainty of deductive inferences, inductive inferences, and guesses.

Children and adults rated their own certainty following inductive inferences, deductive inferences, and guesses. Beginning in kindergarten, participants rated deductions as more certain than weak inductions or guesses. Deductions were rated as more certain than strong inductions beginning in Grade 3, and fourth-grade children and adults differentiated strong inductions, weak inductions, and informed guesses from pure guesses.

Age-related changes in children's and adults' explanations of interpersonal actions.

We investigated the content of children's and adults' explanations of interpersonal actions. Participants were 5-, 7-, and 9-year-old children, as well as adults, who were presented with 8 stories containing either prosocial or antisocial target actions, and asked to explain why each actor performed that action. In half of the stories, an interpersonal event preceded the action.

Development of children's understanding of cognitive activities.

Children's understanding of cognition increases greatly between early childhood and adolescence. This increase provides a developmental bridge between young children's understanding of mental states to adolescents' and adults' epistemological reflection. The author presents a framework for describing developmental changes in children's understanding of cognitive activities.

Children's understanding of reputations.

In the present study, the authors investigated age differences in children's understanding (a) that a person's behavior may contribute to the formation of a shared opinion within the peer group and (b) that origins of a reputation can be direct or indirect. The authors read stories in which a target character engaged in either prosocial or antisocial interactions with peers to children in kindergarten, 2nd, and 4th grade. They then asked the children to judge how various peers viewed the target character.

Facilitating children's understanding of misinterpretation: explanatory efforts and improvements in perspective taking.

The authors investigated children's understanding of how mistaken beliefs can arise through misinterpretation of ambiguous information. Children (N = 91), aged 4 to 5 years, were given pre- and posttests on their ability to infer a puppet's interpretation of a restricted-view drawing after the puppet had been led to an erroneous expectation about the drawing's identity. Before the posttest, the children received either self-explanation training or other-explanation training in which they explained the source of their own or a puppet's misinterpretations of drawings; a control group received no training.

Children's and adults' evaluation of the certainty of deductive inferences, inductive inferences, and guesses.

Two experiments investigated kindergarten through fourth-grade children's and adults' (N = 128) ability to (1) evaluate the certainty of deductive inferences, inductive inferences, and guesses; and (2) explain the origins of inferential knowledge. When judging their own cognitive state, children in first grade and older rated deductive inferences as more certain than guesses; but when judging another person's knowledge, children did not distinguish valid inferences from invalid inferences and guesses until fourth grade. By third grade, children differentiated their own deductive inferences from inductive inferences and guesses, but only adults both differentiated deductive inferences from inductive inferences and differentiated inductive inferences from guesses.
