Both drawing and language are fundamental and unique to humans as a species. Just as language is a representational system that uses systematic sounds (or manual/bodily signs) to express concepts, drawing is a means of "graphically" expressing concepts. Yet, unlike language, we consider it normal for people not to learn to draw, and consider those…

Differential cognitive performance across cultural contexts has been a standard result in comparative research. Here we discuss how societal changes occurring when a small-scale traditional community incorporates elements from industrialized society may contribute to cognitive development, and we illustrate this with an analysis of the cognitive…

Most research on children's conception of death has probed their understanding of its biological aspects: its inevitability, irreversibility and terminal impact. Yet many adults subscribe to a religious conception implying that death marks the beginning of a new life. Two recent empirical studies confirm that in the course of development, children…

Research in the psychology of mathematics education has been confronted with the fact that people blatantly fail to solve tasks they are supposed to be able to solve correctly given their available domain-specific knowledge and skills. Also researchers in cognitive psychology have encountered such phenomena. In this paper, theories that have been…

This paper argues that the metaphorical representation of concepts and the appropriation of language-based construals can be hypothesized as additional sources of conceptual change alongside those previously proposed. Analyses of construals implicit in the lay and scientific use of the noun "energy" from the perspective of the theory of conceptual…

The theory of conceptual fields is a developmental theory. It has two aims: (1) to describe and analyse the progressive complexity, on a long- and medium-term basis, of the mathematical competences that students develop inside and outside school, and (2) to establish better connections between the operational form of knowledge, which consists in…

Philosophers and scientists seeking to conceptualize consciousness, and subjective experience in particular, have focused on sensation and perception, and have emphasized binding--how a percept holds together. Building on a constructivist approach to conception centered on separistic-holistic complexes incorporating multiple levels of abstraction,…

The major tenets of Piagetian theory, such as adaptation and constructionism, are compatible with a cross-cultural approach to the study of cognitive development, but there have been significant methodological and theoretical advances over the past 40 years. Piagetian theory directly influenced three phases of cross-cultural research, ranging from…

While recognizing major contributions of the contemporary theory-of-mind framework, we identify conceptual and cultural gaps with respect to its inattention to deontic considerations. The framework has tended to portray behavior as purely self-directed, thereby neglecting everyday reasoners' understanding of behavior as normatively based. However,…

Adolescence is a period of marked change in the person's cognitive, physical, psychological, and social development and in the individual's relations with the people and institutions of the social world. These changes place adaptational demands on adolescents, ones involving relations between their actions upon the context and the action of the…

The assumption of domain specificity has been invaluable to the study of the emergence of biological thought in young children. Yet, domains of thought must be understood within a broader context that explains how those domains relate to the surrounding cultures, to different kinds of cognitive constraints, to framing effects, to abilities to…

Both Vygotsky, a psychologist, and Halliday, a social linguist, argue for the central role of language in human development. Language is the principal mode of meaning making; it mediates both the communication through which thinking with others is made possible and also the inner speech through which individual thinking is brought under conscious…

Wertsch's clarification of Vygotsky's claims about the role of social interaction in the development of children's thinking made an important contribution to educational research. Revisiting that clarification, I suggest that "talk" instead of "speech" best describes Vygotsky's concern with the functional dynamics of dialogue rather than the…

The developmental psychology of mathematical thinking and the clinical interview method can make major contributions to education by transforming the process of formative assessment--the attempt to use information concerning student performance, knowledge, learning potential, and motivation to inform instruction. The clinical interview is a…

Developmental psychologists have a long history of using triangle metaphors to conceptualise the social constitution of psychological development. In this paper, we present a genealogy of triadic theories, to clarify their origins, distinctions between them, and to identify key themes for theoretical development. The analysis identifies three core…
