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…

The seven papers in this issue address a variety of challenges that parents in several different cultural places encounter as they do their best to ensure their children's safe, happy, and successful development from infancy through middle childhood: infant sleep, developmental agendas, temperament, preschools, academic success, and learning to be…

Contrary to the substantial amount of research on infant, preschool, adolescent, and adult attachment, middle childhood has long been neglected by the international attachment research community. In the past two decades, however, there has been a steep increase in research focusing on middle childhood attachment. This article provides an overview…

In this brief essay, I comment on the constellation of papers published in the current issue. I argue that it represents the new beginning of the new era for the journal, driven by several considerations. Among these, three are key. First, the collection of articles in this issue is explicitly concerned with the multivariate and multidisciplinary…

Middle childhood is a key transitional stage in the development of attachment processes and representations. Here I discuss the middle childhood transition from an evolutionary-developmental perspective and show how this approach offers fresh insight into the function and organization of attachment in this life stage. I begin by presenting an…

This commentary discusses the articles that comprise this special issue on attachment in middle childhood. Central to this discussion is the distinction between verbal, strategic, and conscious responses to questionnaires as compared to verbal and nonverbal, automatic and largely unconscious responses to interviews. Both methods have been…

From the moment children say "mine!" by two years of age, objects of possession change progressively from being experienced as primarily unalienable property (i.e., something that is absolute or nonnegotiable), to being alienable (i.e., something that is negotiable in reciprocal exchanges). As possession begins to be experienced as alienable, the…

Both organismic and intentional self-regulation processes must be integrated across childhood and adolescence for adaptive developmental regulations to exist and for the developing person to thrive, both during the first two decades of life and through the adult years. To date, such an integrated, life-span approach to self-regulation during…

The study of siblings has become increasingly central to developmental science. Sibling relationships have unique effects on development, and sibling designs allow researchers to isolate causal mechanisms in development. This volume emphasizes causal mechanisms in the social domain. We review the preceding chapters in relation to six topics: a…

This chapter explores paths toward emotion-focused coping among typically developing young children and their more or less average parents--portraying characteristic developmental patterns, demands, and stresses. Emotion-focused coping strategies are effortful and aim to decrease negative emotions in stress-inducing interpersonal contexts. The…

Playing games, particularly pretense games, is one of the areas where young children first enter into collective, conventional practices. This chapter reviews recent empirical data in support of this claim and explores the idea that games present a cradle for children's growing into societal and institutional life more generally. (Contains 2…

Describes child and human development as an eco-cultural project. Focuses particular attention to early development of trust and attachment relationships and the age 5-to-7 transition, wherein cultural goals and psychological well-being are achieved despite limited resources and socioeconomic constraints.

The study of peers who dislike one another, termed mutual antipathies, is being recognized as an important aspect of a child's social world. An overview of this area and a review of the literature concerning mutual antipathies is provided. Particularly of interest is the type of mutual antipathy known as an "enemy" relationship, and…

Close relationships among children and adolescents are ordinarily considered to encompass friendliness and fun. Recent studies, however, reveal that many friendships have dark sides consisting of competitiveness, hostility, and conflict. Relationships based on aversion and antipathy may turn out to have major developmental implications, but more…
