Contributions of domain-general and domain-specific numerical competencies were assessed on first graders' number combination skill (NC) and word-problem skill (WP). Students (n = 205) between 5 and 7 years of age were assessed on 2 aspects of numerosity, 8 domain-general abilities, NC, and WP. Both aspects of numerosity predicted NC when…

Examines the development of a general event representation and the relationship between general and specific event memories among kindergarten children who were interviewed about the school-day routine four times during the first three months of school. (Author/RH)

The Piagetian concept of horizontality was studied in 195 fifth graders to determine the relationship between this concept and memory. (ST)

Two tasks were used to evaluate the relationship between concept usage and the organization of knowledge in semantic memory for 7-, 11-, 15-, and 18-year-old subjects. (JMB)

A total 72 children of 3 1/2, 5 1/2, and 7 1/2 years were asked questions about their behaviors and internal states, and of a best friend and an acquaintance. Results indicated even young children have concepts of themselves and other persons that are not restricted to specific points in time and may form basis for later dispositional conceptions.…

Examines developmental change in processes used to retrieve information from semantic memory. Twenty-nine 8-, 12-, and 21-year-olds were asked to name as many animals and pieces of furniture as they could in separate 7-minute intervals. Results suggested that information in semantic memory changes with age, but that retrieval processes do not.…

Examines the role of basic cognitive-processing efficiency as the source of developmental variance in cognitive performance. Two experimental tasks, memory and visual scanning, were used to investigate age effects on the search-processing parameter. Subjects were 9-, 11-, 13-, and 15-year-old children. (CM)

Two concept-formation experiments were conducted with groups of American and Liberian Ss differing in age and educational background. (Authors)

Examined developmental changes in the use of distance-based and calendar-based approaches to estimate the recency of two events. Found that children's ability to discriminate temporal relationships between two events appears by four to five years of age. In contrast, use of calendar information and cognizance of annual patterns was found only in…

Identified social schema by correlating memories of problematic encounters with self-esteem for 84 adolescents and adults. Found that adolescent self-esteem is localized in relationships with peers rather than parents and is based on different relational schema for females compared with males, suggesting need for preventive interventions to…

Two experiments examine use of defining, characteristic, category, and identical semantic features of word concept information in cued recall. College adults and 7- to 11-year-old children were shown word triplets in which context words were related or unrelated to final target word. Results suggest meaning features differ in providing medium for…

Examined 8- and 10-year olds' understanding of the unique features of and potential relations among mental activities. Found a developing tendency to organize mental activities on the degree to which memory was a component of the activity. Results suggest that a constructivist theory of mind develops in later childhood. (AA)

Investigated the effect of using gender as a functional category in elementary school students' gender stereotyping. Results support the idea that the functional use of gender categories leads to increases in gender stereotyping, particularly among those children with less-advanced classification skills. Advanced classification skills proved to…
