Counting is an evolutionarily recent cultural invention of the human species. In order for humans to have conceived of counting in the first place, certain representational and logical abilities must have already been in place. The focus of this article is the origins and nature of those fundamental mechanisms that promoted the emergence of the…

An individual's identity related to health is critically important in terms of the adoption and maintenance of health behaviors, and guides approaches to health change across the lifespan. This article presents a review of the literature and proposes a health socialization and health identity framework, which may be used to clarify challenges in…

Niche construction is the modification of components of the environment through an organism's activities. Humans modify their environments mainly through ontogenetic and cultural processes, and it is this reliance on learning, plasticity and culture that lends human niche construction a special potency. In this paper we aim to facilitate…

Youth homelessness is a growing concern in the United States. Despite difficulties studying this population due to inconsistent definitions of what it means to be a youth and homeless, the current body of research indicates that abuse, family breakdown, and disruptive family relationships are common contributing factors to youth homelessness.…

This paper reviews the recent literature on the production of skills of young persons. The literature features the multiplicity of skills that explain success in a variety of life outcomes. Noncognitive skills play a fundamental role in successful lives. The dynamics of skill formation reveal the interplay of cognitive and noncognitive skills, and…

This article is a comparative discussion of women's and men's development through an analysis of two current influential works. The discussion focuses upon the themes found in "Women's Ways of Knowing: The Development of Self, Voice and Mind" (Belenkv, Clinchy, Goldberger & Tarule, 1986) and "Iron John: A Book about Men"…

Developmental contextualism focuses on changes in fused relations between developing people and their changing contexts. Research on cognitive training in the aged years provides evidence about plasticity throughout life because it alters developmental trajectories through revised person-context relations. The studies in the current issue support…

Examines the role attributed to cultural mediation in Piaget's and Vygotsky's theories. Mediation of human action by cultural artifacts was central to Vygotsky's account of human development, but less important for Piaget. Vygotsky's claims regarding social origins of individual mental processes need to be understood in light of claims regarding…

Piaget's theory has been characterized as descriptive and not explanatory, not qualifying as causal explanation. Piaget was consistent in showing how his theory was both explanatory and causal. Vygotsky also endorsed causal-genetic explanation but, on the basis of knowledge of only Piaget's earliest works, he claimed that Piaget's theory was not…

A social development theory of self is introduced as a framework for developmental psychopathology. Built on some of Piaget's principles, the theory is taken into the social domain and used to define the movements of self and important others throughout life. (PCB)

Compares Piaget's and Vygotsky's interpretations of transmission and transformation. Notes that differences are apparent in the preformation of knowledge, availability of a third alternative to nature and culture, and unity and identity in social interaction. Vygotsky was concerned about the novel transformation of the learner; Piaget, with the…

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…

Notes contemporary models of human development have expanded to address a wider set of issues underlying personal change. Discusses the social cognitive model of self-regulatory development. Emphasizes the crucial development of self-regulatory competence: the point at which the processes of development become fully and reciprocally interactive…

Discusses the two major theoretical traditions from which the ideas discussed in the Noam (PS 524 984) and the Cicchetti (PS 524 985) articles in this issue are drawn. Describes their divergences from traditional Piagetian and attachment theorists, and the approaches each has taken to common themes in their work. Concludes by setting out…

Argues that the limited resources with which organisms start their development make possible certain kinds of learning which otherwise would be highly problematical. Discusses limitations of the cognitive structure of the organism, learning, and its problems in connectionism. Maintains that the knowledge gained from efforts to overcome problems…
