The effects of rewards on executive function (EF) reflect bidirectional interactions among motivational and executive systems that vary with age and temperament. However, methodological limitations hinder understanding of the precise influences of incentives on early EF, including the role of reward sensitivity. In this within-subjects study,…

Narcissism--a strong need to be admired for a grandiose self--is a problematic personality trait for children as well as adults. This study of 236 preadolescents (M age = 11.3 years; 129 girls, 107 boys) evaluated 2 intrapersonal (cognitive) pathways by which narcissism might contribute to maladjustment. The first was that narcissism combines with…

In one of the first open diffusion experiments with young children, a tool-use task that afforded multiple methods to extract an enclosed reward and a child model habitually using one of these methods were introduced into different playgroups. Eighty-eight children, ranging in age from 2 years 8 months to 4 years 5 months, participated. Measures…

Trait attribution is central to people's naive theories of people and their actions. Previous developmental research indicates that young children are poor at predicting behaviors from past trait-relevant behaviors. We propose that the cognitive process of behavior-to-behavior predictions consists of two component processes: (1) behavior-to-trait…

This study contrasted two possible relations between reflection-impulsivity and analytic or holistic modes of processing. Although impulsive children were more holistic in the classification task, they made more errors than reflectives on matching tests, regardless of whether the content favored holistic processing.

Investigated the relation between 7- and 8-year-olds' interpretations of human behavior and children's beliefs about the stability of human traits. Found that the belief that traits are stable predicted a greater tendency to make trait judgments in the academic and sociomoral domains, and an increased focus on outcomes such as performance and…

The development of moral judgment in 11-year-old girls is discussed in terms of the evaluation of role taking ability. (ST)

The hypothesized central role of cognitive development in resolving moral dilemmas was examined in sixth grade and college-age females. Results indicated that sophisticated cognitive operations are a prerequisite to advanced moral judgments. (ST)

Evaluated a conceptual model that links temperament, emotional knowledge, and family expressiveness to preschoolers' emotional regulation ability by giving "disappointing" prizes after a task. Subjects were 82 preschoolers. Found that children's positive displays when presented the disappointing prize were inversely related to the…

Examines the implications of temporal separation for children's developmental differences in inferences drawn about an individual's characteristics after observing multiple instances of that individual's behavior. Also tests two competing hypotheses about how young children process information separated in time. (HOD)
