Young children's use of motives and outcomes as criteria for moral judgments was measured under three modes of story presentation and several different combinations of positive and negative motives and outcomes. Recall for the critical story information was also assessed. (Author/RH)

Explores the hypothesis that representation, as measured by object permanence attainment, is the main prerequisite for language acquisition. Differing definitions of representation, differing assumptions about cognitive stages, and differing criteria for assessing cognitive abilities such as object permanence may account for some of the divergent…

Preschool children ranging in age from three to five years were presented with an array of moral judgment tasks designed to assess their understanding of differing moral criteria. Results showed that older children correctly understood more criteria and that understanding of the relevant moral distinctions was developmentally ordered. (JMB)

Preschoolers named and gave reasons for liking/ disliking an actual best friend and an actual enemy. Questioning of parents and observation of subjects' free play were conducted to verify the existence of close, reciprocal friendships. Content analyses of subjects' responses revealed that different dimensions underlie unilateral and reciprocal…

Investigated 6-, 8-, and 10-year-olds' reasoning about laws and legal compliance. Found that children considered several factors in their judgments, including perceived justice of the law, its socially beneficial purpose, and potential for infringement on individual freedoms and rights. Found that children apply moral concepts of harm, rights, and…

Defines structural equation modeling (SEM) and points out its relation to other more familiar data-analytic techniques, as well as some of the potentials and pitfalls of SEM in the analysis of developmental data. Discussion focuses on causal modeling, path diagrams, ordinary least-squares regression analysis, and powerful methods for model…

Used computer simulations to examine effectiveness of different criteria for measuring infant visual habituation. Found that a criterion based on fitting a second-order polynomial regression function to looking-time data produced more accurate estimation of looking times and higher power for detecting novelty effects than did the traditional…

Examined differences between five-, seven-, and nine-year-olds' ability to estimate their counting accuracy for large set sizes on tasks of three levels of counting difficulty. With increasing age, children's estimates of their counting accuracy increasingly corresponded to their actual counting accuracy. (Author/DB)

In a series of five experiments, young children (two- and three-year-olds) were presented with novel objects in which perceptual and functional features varied independently. Results indicate that early conceptualizations and word meanings are perceptually based when perceptual and functional features are independently available. (Author/RH)

Tracked social networks and friendships over a 3-week period for 132 fourth graders and seventh-graders. Found that, when loose criteria for stability were employed, high stability was found in friendships and social group membership. However, when stringent criteria were employed, only modest social relationship stability was observed. (MDM)

Examines elementary school children's concept of authority with regard to the age and social position of command-giver and the type of command given. Shows that children's evaluation of adult and peer authority were based on a combination of age and position in the social context. (HOD)

Reports on two studies during which 6-, 8-, and 10-year-old children were interviewed about three different types of regularities or rules: social conventions, physical laws, and logical necessities. Shows that older children made more distinctions between social and nonsocial items than did younger children. (HOD)

Investigates whether 7- and 10-year-old children and adults are sensitive to their own and another listener's failure to understand literal and nonliteral (sarcastic) uses of utterances. (HOD)

Type A and Type B children's efforts to achieve were investigated. Type A's solved more arithmetic problems than did Type B's in a no-deadline condition. Type A's held a weight, which matched individual hand strength, 50 percent longer than did Type B's. Ambiguous performance criteria seemed to increase Type A efforts to excel. (Author/DB)

Identifies the forces that influence how developmental research is prioritized and evaluated and how these influences are changing at entry into the new millennium. Considers the developmental researcher in context, suggesting that there will be increasing pressure to use new criteria when assessing the significance of twenty-first-century…
