Bayesian methods offer many advantages when applied to psychological research, yet they may seem esoteric to researchers who are accustomed to traditional methods. This paper aims to lower the barrier of entry for developmental psychologists who are interested in using Bayesian methods. We provide worked examples of how to analyze common study…

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…

This handbook offers comprehensive coverage of the topics that are relevant to the field of adolescent and young adult development. The "APA Handbook of Adolescent and Young Adult Development" reviews the many factors that impact youth development across varying themes including biological underpinnings, cognitive and emotive processes,…

We define and describe how subitizing activity develops and relates to early quantifiers in mathematics. Subitizing is the direct perceptual apprehension and identification of the numerosity of a small group of items. Although subitizing is too often a neglected quantifier in educational practice, it has been extensively studied as a critical…

Addressing practical issues rarely covered in methods texts, this user-friendly, jargon-free book helps students and beginning researchers plan infant and child development studies and get them done. The author provides step-by-step guidance for getting involved in a developmental laboratory and crafting effective research questions and proposals.…

In the United States today, roughly 1 in 25 children has a parent in prison. This insightful volume provides an authoritative, multidisciplinary analysis of how parental incarceration affects children and what can be done to help them. The contributors to this book apply a wide array of tools and perspectives to the study of children of…

Existing data sets can be an efficient, powerful, and readily available resource for addressing questions about developmental science. Many of the available databases contain hundreds of variables of interest to developmental psychologists, track participants longitudinally, and have representative samples. In this article, the authors discuss the…

Over the past thirty years, researchers have documented a remarkable growth in children's social understanding between toddlerhood and the early school years. However, it is still unclear why some children's awareness of others' thoughts and feelings lags so far behind that of their peers. Based on research that spans an extended developmental…

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…

Matching methods such as nearest neighbor propensity score matching are increasingly popular techniques for controlling confounding in nonexperimental studies. However, simple k:1 matching methods, which select k well-matched comparison individuals for each treated individual, are sometimes criticized for being overly restrictive and discarding…

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)

Reviews Habermas's concept of communicative action and the life world, a concept refering to concrete interpersonal relations. (RH)

Criticizes action theory for neglecting motivations that remain outside of consciousness and argues that individual goals or intentions are comprehensible only retrospectively and in the context of social discourse. Aspects of false consciousness, consciousness and levels of intention, action as dialog, and political power are explored. (RH)

To test their skill with spatial relationships, 4- to 6-year-olds were given problems in which they had to decide which one of an array of points was in line with two coordinate markers. Results establish that young children's grasp of Euclidean spatial relationships is more adequate than has been suggested. (Author/BE)

Emphasizes the social and interpersonal aspects of actions, especially as described in Soviet psychology. Argues that remembering is essential for intentional action. Intentional action is derived from the communication and cooperative relations between two people. (RH)
