An evolution-based framework for understanding biological and cultural influences on children's cognitive and academic development is presented. The framework, which defines biologically primary and secondary classes of cognitive ability, is a foundation for examining current approaches to reform and mathematics instruction in the United States.…

This article describes the use of problem-based learning (PBL) with gifted students, in which the focus of the curriculum is "ill-structured" problems. Particular advantages of PBL with these students include effectiveness in teaching the art of problem finding and solving, active learning, higher order thinking skills, and using interdisciplinary…

Studied 100 adolescents' approaches to problem-solving proofs and reasoning competence tasks. Found that a formal level of reasoning competence is associated with a deductive approach. Results support the notion of a cognitive development progression from an inductive approach to a deductive approach. (ETB)

Positive and negative peer nominations of multiple competencies and incidental recall of positive and negative self-referential adjectives were measured in relatively depressed and nondepressed children from 9 to 15 years old. The relationship between recall of negative information and depression related strongly to children's self-reported…

Discusses the critical links between children's social and cognitive development in light of findings of the Cost, Quality, and Child Outcomes in Child Care Centers study discussed in this issue. Highlights some observations of the study. Examines public notions regarding child care and the need to increase awareness of circumstances from which…

Data were analyzed from the postcollege phase of a 7-year longitudinal study of college students' (n=101) epistemological development. The data revealed that the gender-related patterns of relational and impersonal knowing that these students demonstrated during college were integrated into postcollege experience in work, education, and personal…

Examined children's notions about segments of written sentences. Subjects watched a sentence being written and listened to it being read. The interviewer then asked questions about each word--whether or not it was written and, if so, where. Found that children used word order before phonics to figure out what was written in each segment of the…

This study examined whether 3-year-olds could be persuaded to identify a stranger labelled "daddy" as their father. Five of the 17 children misidentified a photograph as their father when the question was repeated. Results suggest that young children's responses to questions of fact are influenced by contextual factors, and have…

Examined the variability in the development of moral judgment by reanalyzing a set of Kohlberg's data studies on the concept of structured wholeness, a deep cognitive organization unifying different surface judgments given by the same subject. Although the results failed to show total consistency they also show that it is not meaningful to claim…

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…

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…

Examines the use of tasks with backward false belief explanation as an effective technique in gaining a complete picture of the development of understanding of the representational mind. Argues that traditional prediction tests of false belief cannot tell whether children's wrong answers show misunderstanding about false belief or seduction by the…

Reviews the literature on the relation between early memory development and corresponding changes in brain development of infants. Finds that an adult-like form of explicit memory emerges between 8 and 12 months of age, drawing heavily on limbic and cortical structures. Offers theoretical perspectives for studying the ontogeny of memory. (JW)

Two experiments examined whether 40 infants would reenact what an adult did or intended to do: (1) infants observed an adult unsuccessfully attempt to complete 4 target acts; and (2) children observed a mechanical device tracing the adults' actions. Infants could infer adults' intentions and imitate target acts, suggesting that children can…

Compared children's performance on initial-unknown and final-unknown problems involving the addition or subtraction of a single item. Found that although 4-year olds responded in a directionally appropriate way to the final-unknown problems but not to the corresponding initial-unknown ones, 5-year olds were able to respond appropriately to both.…
