The importance of the specific environment for understanding the microgenesis of psychological processes is well documented. It can be argued, however, that the theoretical framework of cultural psychology which is usually referred to as cultural-historical activity theory (CHAT) underconceptualizes this aspect, thereby hampering its ability to…

This paper introduces and exemplifies a qualitative method for studying learning, "microgenetic learning analysis" (MLA), which is aimed jointly at developing theory and at establishing useful empirical results. Among modern methodologies, the focus on theory is somewhat distinctive. We use two strategies to describe MLA. First, we develop a…

Social domain theory (SDT) provides a model for how individuals identify, evaluate, and coordinate domains of social knowledge when judging socially relevant actions. To date, little research has focused on the cognitive processes that underlie these capacities. Utilizing principles from the literature on SDT and the hierarchical competing systems…

The goal of this paper is to contribute to the revival of Heinz Werner's organismic-developmental theory by considering some of its key claims in relation to contemporary developmental theory and research. The organismic-developmental definition of development in terms of differentiation and integration is first discussed in relation to…

This paper poses the following question: When, in spite of knowing that it is wrong, people go on to hurt others, what does this mean for the development of moral agency? We begin by defining moral agency and briefly sketching relations between moral agency and other concepts. We then outline what three extant literatures suggest about this…

This paper addresses the relationship between identity and learning and how their integration in adolescence is an important part of short- and long-term developmental dynamics. We discuss how social practice theories can be expanded from a position termed "transformative activist stance" that puts emphasis on collaborative practice aimed at…

Studying human development involves describing, explaining, and optimizing intraindividual change and interindividual differences in such change and, as such, requires longitudinal research. The selection of the appropriate type of longitudinal design requires selecting the option that best addresses the theoretical questions asked about…

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…

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…

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…

In this article, we discuss a qualitative study carried out in a cultural contact zone. Irish nationals, immigrants, and asylum seekers in Cork, Ireland, were interviewed about their cultural identities and future trajectories. Cultural Continuity theory was used as a model to offer an insight into the processes and strategies of the Dialogical…

Game theory has been one of the most prominent theories in the social sciences, influencing diverse academic disciplines such as anthropology, biology, economics, and political science. In recent years, economists have employed game theory to investigate behaviors relating to fairness, reciprocity, and trust. Surprisingly, this research has not…
