Hunger, thirst and satiety have an enormous influence on cognition, behavior and development, yet we often take for granted that they are simply inborn or innate. Converging data and theory from both comparative and human domains, however, supports the conclusion that the phenomena hunger, thirst and satiety are not innate but rather emerge…

Although thermal conditions influence the development of living organisms in a wide variety of ways, this topic has been recently ignored in humans. This paper reintroduces thermal conditions as a topic of importance for developmentalists by presenting an example of how thermal conditions are hypothesized to influence a particular developmental…

Examines Simmel's principle of cultivation whereby the cultivated mind is constructed through ongoing transactions of people with their cultural environment, cultural forms currently overlooked. Cultural forms result from externalizations of former person-culture transactions. Argues that development is structured through person-culture…

Maintains that Madole and Oakes' hypotheses are incorrect. Shows that conceptual development frequently goes from the abstract to the concrete and that extensive literature shows that there is more than one kind of categorization. Discusses ways in which perceptual and conceptual categorization differ. (Author/KB)

Provides a basis from which to critically examine contemporary identity research, by offering a definition of identity, a constructive criticism of the subject approach, and an empirical approach to studying sense of identity. The empirical approach is based on conceptually sound ideas and leads to important questions about identity modes and the…

Proposes an account of the development of temporal understanding, linking it with episodic memory development. Distinguishes between ways of representing time in terms of frameworks involved; describes perspectival and nonperspectival frameworks and those representing recurrent sequences or particular times. Describes emergence of new kinds of…

Responds to Mandler's critique of authors' view of infant categorization. Maintains that their view of infant categorization is not characterized by a shift from one type of category to another but by gradual changes in the kinds of information infants can use in forming categories. Clarifies position regarding a single categorical process using…

Considers how students' mathematical thinking evolves as a result of their actions and everyday experiences and from increasing reliance on introduced mathematical principles and representations. Exemplifies how 8- to 10-year-olds' personal representations come to face with representations involving algebraic concepts. Explores implications for…

Responds to calls for combining the ideas of Piaget and Vygotsky, discussing differences between the two perspectives. Notes that differences are found in underlying assumptions about the nature and process of development, philosophy, stages of development, developmental influences, and the integrity of cognitive structures. Suggests that, given…

Addresses the extent to which differences in Piagetian and Vygotskyan psychologies make their theories incompatible. Differences result from a Vygotskyan belief in a material primary cause for development; Piagetians do not hold this view. Explores this difference in perspective, concluding that, despite it, the two approaches are compatible. (JW)

Demonstrates the need for a process-oriented, constructivist approach to understanding infants' categorization abilities. Suggests that emphasizing the distinction between perceptual and conceptual categorization has been an obstacle to forging an approach. Proposes a more microanalytic consideration of features available to infants at different…

Reviews literature on human fetal behavior. Includes descriptions of coupling of body movements and fetal heart rate and behavior maturation from conception to term. Discusses use of stimulus-induced behavior to examine sensory and cognitive development, and spontaneous and stimulus-induced behavior to assess fetal well-being. Notes research focus…

Discusses the influence of Levy-Bruhl's analysis (1910) of "primitive" mentality on Piaget's research and theory contrasting child and adult ontology and logic. Maintains that parallels between their research designs substantiate Piaget's explicit references to Levy-Bruhl. Suggests that their conceptual kinship has implications for an…

Reviews development of rehearsal and organizational strategies based on cross-sectional and longitudinal research, focusing on the Munich Longitudinal Study. Found that longitudinal data reveal greater individual variability in strategy acquisition, suggesting that canonical development patterns inferred from cross-sectional studies obfuscate…

Introduces the concepts of online and offline sampling and highlights the role of online sampling in agent-based models of learning and development. Compares the strengths of each approach for modeling particular developmental phenomena and research questions. Describes a recent agent-based model of infant causal perception. Discusses limitations…
