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…

The outcomes of collaboration provide an incomplete and potentially misleading picture of cognitive change, one that is clarified by examining the collaborative processes themselves. Results from a study illustrate the dangers of focusing solely on the consequences of collaboration and emphasize why the analysis of collaborative processes is…

Lev Vygotsky maintained that historical and cultural aspects of development started from the point at which humans could first be distinguished from apes. It is critical to consider the dialectical relationship between the individual and the cultural environment in which the child actively masters cultural behavior. Interaction with others…

Researchers concerned with the issue of children's play are urged to read the book "Children's Play: Current Theory and Research" edited by D. J. Pepler and K. H. Rubin which provides an up-to-date review of the conceptual, methodological and developmental issues related to children's play. (MP)

This paper takes the position that theories about individual differences in childhood and theories about cognitive development both would be enhanced if the two lines of research were integrated. The heuristic value of this position is illustrated in the context of analogical reasoning tasks. A general model of analogy solution and potential…

This paper critically examines the portions of Arthur Jensen's books, "Genetics and Education" and "Educability and Group Differences," that concern Barbara Burks' 1928 study of adoptive families. Jensen cites the low correlations of children's IQs with measures of home environment from Burks' study as evidence that environment…

Two opposite views of the relations between moral cognition and moral action are described, their contrasting assumptions and implications are clarified, and the available empirical literature is reviewed. Research relating moral reasoning to real-life moral behaviors is summarized, with special attention given to design, measurement, and…

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…

Two studies attempted to clarify the Intellectual Tasks test assessment of number conservation by testing for two possible artifacts due to procedure: (1) Effects of preceding questions on the following test questions, and (2) operations or manipulations of the test materials by the examiner. Forty Mexican-American first and second graders were…

The authors offer a detailed and systematic critique of Piaget's theory of cognitive development, examining it in relation to other theories of development. Chapter 1 points out some of the problems in building and evaluating scientific theories and considers contrasting approaches to cognitive development (including those which focus on…

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…
