Developmental scientists are often interested in subgroups of people who share commonalities in aspects of development; these subgroups often cannot be captured directly but instead must be inferred from other information. Mixture models can be used in these situations. Two specific types of mixture models, latent profile transition analyses and…

Developmental research often involves studying change across 2 or more processes or constructs simultaneously. A natural question in this work is whether change in these 2 processes is related or independent. Associative latent transition analysis (ALTA) was designed to test hypotheses about the degree to which change in 2 discrete latent…

The symposium is described as being devoted to the question of whether and to what extent action may constitute a useful paradigm for developmental psychology, where action is understood as voluntary behavior employed by the agent as a means of attaining certain ends. (Author/RH)

Points out that while some symposium papers pursue a model of the individual mind, others explore the social mind. Argues that concepts of cognitive theory originally based on social existence have been deformed to emphasize the individual as a self-contained entity.(RH)

Summarizes the general perspectives represented in the symposium and attempts to reconcile them by reconstructing a dialog between them. Issues addressed include the intersubjective nature of intentionality, the nature of action theoretical explanations, and the distinctive characteristics of action theory. (RH)

An action theoretic account of skill learning and skill use is offered as a useful heuristic for life-span developmental psychology. The version presented is one that is particularly prominent in industrial psychology in the German-speaking countries. (Author/RH)

Reflects on G. Zivin's framework on the development of expressive behavior. Stresses the need to include noncognitive, as well as cognitive, affective activation in the framework, and the necessity for the adoption of an inclusive, synthesizing strategy at this stage of knowledge. (HOD)

Describes the symposium on action theory presented at the 1983 meeting of the International Society for the Study of Behavioral Development in Munich. The symposium included reactions to action theory from a variety of theoretical perspectives. (Author/RH)

Details some problematic features of G. Zivin's framework on the development of expressive behavior. (HOD)

This review draws together research by developmentalists on parents' ideas about parenting and development, and research in social psychology on attitudes, schemas, and social categorization. (PCB)

This chapter discusses the "person approach" to studying developmental processes by focusing on the distinction and complementarity between this holistic-interactionistic framework and what has become designated as the variable approach. Particular attention is given to measurement models for use in the person approach. The discussion on the…

Considers possible contributions of developmental psychology to analysis and solution of practical problems by proposing a practical action model comprising the following: nature of the phenomenon or problem; existence of the phenomenon or problem; outcome in case of no intervention; goals for intervention; achievement of goals; and assessing…

This book examines critical issues in classification and definition of learning disabilities; the development of theory in learning disabilities; the development of cognitive, developmental, and educational models of learning disabilities; and social and public policy in learning disabilities. After an introductory chapter by G. Reid Lyon and…

A paradigm for learning economic concepts based on cognitive development and learning theory is offered as a guideline for teaching and research. Discussion is divided into two sections. The first section establishes the model's theoretical framework, which is based on two propositions. The first of these is that economic knowledge is not a fixed…
