Finds support for the global trend hypothesis which posits that cognitive processing speed changes as a function of age and all component processes change at the same rate. (PCB)

Argues that dynamic systems approaches may provide an explanatory framework based on general scientific principles for developmental psychology, using principles of self-organization to explain how novel forms emerge without predetermination and become increasingly complex with development. Contends that self-organization provides a single…

An assessment of the occurrence of three forms of humor (responsive, productive, and hostile) during the activities of 30 nursery school children. The three humor forms were not significantly correlated. The relation of the ongoing activities and the pattern of humor exhibited, along with the significant sex differences in humor expression are…

Two studies tested whether 12- and 24-month olds' self-knowledge differed from their knowledge of others (mother or inanimate object), or whether toddlers' knowledge of persons (self and mother) differed from knowledge of objects. Results showed that 12-month olds were more sensitive than older toddlers to perceptual features of objects. Data were…

Maintains that authors' meta-analytic findings make early competence accounts of theory of mind increasingly unlikely. Asserts that findings argue against executive function expression accounts, including that advocated by Scholl and Leslie (PS532407). Explains that meta-analytic findings directly contradict Scholl and Leslie's predictions…

Developmental changes in conditions engendering pride and embarrassment were explored. Among other results, developmental change was found in the standards used to evaluate emotional experiences; references to social comparison increased with age and references to mastery decreased. (PCB)

Three studies examined the developmental relationship between early linguistic and cognitive achievements. Findings showed that children's ability to classify objects in a spatial or temporal order was independent of advances in productive vocabulary growth, suggesting that developments in categorization and naming depend on abilities in addition…

Interview responses of 72 fifth-, eighth-, and eleventh-graders revealed developmental changes in the scope and nature of perceived peer influence and in the extent to which peer group reactions have an impact on self-evaluations. Developmental changes in the apparent reference-group functions of peer groups for adolescent identity formation are…

Examined four and seven year olds' recall of standard features of a repeated event as opposed to features that deviated from that event. Younger children had more difficulty determining which features occurred in the events. Concludes that younger children organize their memory for general and specific event episodes differently than older…

Investigated genetic change and continuity within the domains of temperament, emotion, and cognition and language for 200 pairs of twins assessed at 14 and 20 months of age. Correlations of measures at the two ages indicated that individual differences in the second year of life showed greater change than continuity on most measures. (MDM)

Subjects were 30 participants at each of 4 ages: 5, 7, and 10 years, and adult. Subjects described objects ordered in pairs. Children of 5 and 7 years improved their ability to understand visual metaphors which display a topic-visual interaction. From age 5 to adulthood, subjects improved their ability to comprehend metaphoric similarity. (RH)

When pioneering longitudinal studies of child development extended into adulthood, they generated issues that could not be addressed satisfactorily by available theories, including the recognition that individual lives are influenced by their ever-changing historical context and that human development concepts should apply to processes across the…

Fifth through eighth graders completed self-reports in response to pager signals received over one week and again four years later. Responses indicated that thinking about the opposite sex occurs earlier than spending time with the opposite sex alone and that both increase over time. Girls spent more time with opposite sex and more time thinking…

Focuses on the conceptual implications of analyses of individual differences in francophone post-Piagetian research. Maintains that these analyses are preoccupied by the "American question" of measurement and method, instead of attempting a theoretical account of the issues raised by intraindividual and interindividual variability in…
