The current article discusses the importance of increasing racial-ethnic and socioeconomic diversity in cognitive developmental research. It begins with discussion of the implications of the underrepresentation of ethnic minority children in cognitive developmental research. It goes on to suggest reasons underlying these omissions, such as the…

To examine Fodor's (1992) argument that standard false belief tasks used in developmental research seriously underestimate young children's understanding of false belief, three- and four-year-old children were given three tasks of action prediction and explanation, belief preduction, and knowledge prediction and explanation. The overall pattern of…

Suggests that, with the waning influence of Piaget and shortcomings of information-processing perspectives of cognitive growth, cognitive developmentalists lack a metatheory to guide their research. Posits developmental biology as metatheory for cognitive development. Introduces basic principles of evolutionary psychology, and examples of…

Maintains author's interpretation of 6-month-olds' behavior is consistent with task requirements in the 2000 study and previous work showing that infants use explanatory inferences to make sense of their world. Asserts that ability to understand that people communicate with persons but act on objects is precursor to infants' understanding at 9 to…

Although Piaget's theory remains the most impressive in its field, there are reasons for caution: its tenuous base in good data, overemphasis on failures or successes of logical structure as explanations of behavior, underemphasis on the possibility that much knowledge is socially constructed and transmitted, and the central but dubious tenet of…

Presents two reasons for abandoning the false belief task as a methodology for theory of mind: (1) passing the false belief task requires ability other than theory of mind; and (2) theory of mind need not entail the ability to reason about false beliefs. Concludes with an alternative conception of the role of the false belief task. (Author)

Comments on Damon and Killen's study, pointing out that the methodological difficulties in examining spontaneous moral discussions have led to the appropriation of a dyadic social-cognitive conflict paradigm that focuses on dialogic interaction. (Author/RH)

Interviews with adolescents revealed that they have a complex "divided metaphysics" of subjectivity, based on a dualistic view of reality versus appearance. Certain conceptual methodological issues surrounding research into self identity are discussed. (Author/DB)

Philosophical tendencies in Kohlberg's cognitive-developmental theory of moral development such as apriorism, absolutism and formalism are unfavorably contrasted with the dialectical categories of historicism, double interactionism and reflection. In logic and epistemology the cognitive-developmental theory is shown to be based on a subjective…

Proposes an interference explanation of data from dual-task studies of memory development. Dual-task data support the resources hypothesis that memory processes tax a common pool of cognitive energy, which has been variously called attentional, mental effort, and working-memory capacities. Suggests that dual-task deficits are instances of output…

Claims that Campbell and Christopher's literature on moral development construes the cognitive-developmental and domain approaches too narrowly, overinterprets the influence of Kant, excludes other equally important non-Kantian philosophical influences, and ignores much of the research evidence. Describes the need for drawing distinctions in…

Examined matching-to-sample procedures that might result in emergence in preschool children of conditional behavior that was never explicitly taught. Children were asked to match a novel and a familiar picture to a spoken word which was English or nonsense. (SKC)

From a statistical methodological standpoint, criticizes research by Hicks, Langham, and Takenaka, which found significant differences in behavioral and intelligence measures between children with different time periods of participation in the National Special Supplemental Food Program for Women, Infants, and Children (WIC) program.

Argues that developmental psychologists need attitudes, methods, and conceptual schemes that integrate the distinctive contributions of both nature and nurture in order to study change and consistency in developmental functions, as well as individual differences in behaviors of interest. A conceptual scheme for early mental development is…

Discusses problems involved in testing Piaget's hypothesis of topological primacy in representational space by copying geometric figures. (Author/SS)
