Research in non-human animal (hereafter, animal) cognition has found strong evidence that some animal species are capable of meta-cognitively monitoring their mental states. They know when they know and when they do not know. In contrast, animals have generally not shown robust theory of mind (ToM) capabilities. Comparative research uses methods…

The term executive function is used increasingly within developmental psychology and is often taken to refer to unfolding brain processes. We trace the origins of research on executive function to show that the link with social interaction has a long history. We suggest that a recent frenzy of research exploring methods for studying individual…

Individuals with Down syndrome are predisposed to show a specific behavioural phenotype, or a pattern of strengths and challenges in functioning across different domains of development. It is argued that a developmental approach to researching the Down syndrome behavioural phenotype, including an examination of the dynamic process of the unfolding…

Two lines of research on the development of Piagetian concepts are examined in terms of the effects of their methodological procedures on the substantive results of the research. (JMB)

Argues that the simplification strategy of research is useful for understanding the basic cognitive processes that are necessary for mature performance in conservation, transitivity, moral judgment, causal inference, and other Piagetian tasks. (JMB)

Describes the ideas proposed by James Mark Baldwin which anticipated much of Jean Piaget's work. The goals, genetic approach, and epistemological assumptions underlying Piaget's inquiry into cognitive development found explicit statement in Baldwin's work. Discusses Baldwin's current importance for psychology. (Author/CB)

Reports the results of two experiments designed to investigate the story completion preferences of four- through seven-year-old children. It was hypothesized that children at the concrete operational level would prefer "coordinated" completions to the stories over the unidimensional-perceptual (u-p) endings preferred by preoperational…

The development of multiplicative classificatory skills in children between 4 and 9 years of age was investigated by means of two forms of the matrix-completion task. (Authors)

Reviews "The Mind's Staircase: Exploring the Conceptual Underpinnings of Children's Thought and Knowledge," edited by Robbie Case. A main thesis of the book, which discusses theoretical issues and presents empirical evidence, is that children's cognitive development is guided by central conceptual structures, or networks of concepts that…

This paper describes a program of research in the application of scalogram analysis to the validation of learning hierarchies, together with the development of an alternative method for assessing hierarchical relationships among tests of instructional objectives. The relationship between scalability of tests and positive transfer between…

Summarizes researchers' beliefs about cognitive development. Topics include (1) the child as constructive thinker; (2) new research methods; (3) the characterization of children's cognitive development; (4) estimates of children's competence; (5) stages of development; (6) interrelations among developmental skills; (7) mechanisms of development;…

Researchers in the fields of cognitive and language development have made less use of large-scale longitudinal designs and of person-centered approaches to data analysis than have researchers in the fields of social and personality development. It is argued that differences among domains of developmental psychology in the research methods employed…

This paper presents a study designed to determine if groups of concrete and formal operational children can be identified through the technique of cluster analysis, using a battery of Piagetian tasks. A Total of 64 subjects, 8 boys and 8 girls from each of the second, fourth, sixth, and eighth grade levels, were selected from a public elementary…

Presented are findings from numerous studies in terms of a theory which integrates the theoretical position of Piagetian developmental psychology with the concept of the learning set proposed by Harlow. This integrated theory, called the metaset, is offered as a new approach to explaining the efforts of childhood bilingualism. (NQ)

Herman Epstein's theory correlating children's learning capacity with periodic spurts and plateaus in brain growth is predicated on inadequate data and questionable interpretations thereof, and it is discredited by highly respected scholars, including those he cites. Applying this theory to classroom practice is therefore irresponsible and…
