Approaches divorce from a combined family systems, individual life cycle and stage theory of development perspective. Recommends that therapy encompass interventions that are likely to be the most effective in the various stages rather than be a rigid adherence to one dogma. Several illustrative case vignettes are presented. (JAC)

The theory of developmental sequences is extended by introducing the concepts of prerequisite and precursor. It is argued that (1) attention to prerequisites and precursors is necessary for answering questions of sequence existence, membership, and order and that (2) because these concepts are theory dependent, appropriate developmental research…

It is suggested that four developmental terms (period, phase, stage, level) can be distinguished as different combinations of four criterial elements, and they should be differentiated according to whether or not they refer to (1) a part of a progression, (2) a recurrent state or event, (3) quantitative change, and (4) qualitative change.…

The studies presented in this article longitudinally examined preschool children's learning behavior, which has received increased attention in recent years because of its positive influence on school readiness. The first study used a statewide database (N = 23,434) to examine whether and how learning behavior changed over time. The second study…

Multi-age classrooms feature the purposeful grouping of students from two or more grade levels in order to form communities of learners. During the past 40 years, multi-age education has been examined in literature and research in many different ways and contexts. In the subject area of visual art, however, little literature can be found that…

The authors proposed that birth order affects psychosocial outcomes through differential investment from parent to child and differences in the degree of identification from child to parent. The authors conducted this study to test these 2 models. Despite the use of statistical and methodological procedures to increase sensitivity and reduce…

Research Findings: The toddler stage is a unique developmental period of early childhood. During this stage, children are developing autonomy, self-regulation, and language capabilities through interactions with significant adults in their lives. Increasing numbers of toddlers are being enrolled in child care. This article focuses on the need to…

High school students taking college courses that simultaneously fulfill high school requirements and give general education credit toward a bachelor's degree have become more of a presence on college campuses across the nation. The purpose behind these programs appears to be the belief that dual enrollment (also known as "concurrent enrollment")…

Upper elementary children today, while retaining many of the characteristics ascribed to them generations ago by theorists such as Piaget, Erikson, and Kohlberg, are different. Developmental characteristics across multiple domains remain relatively predictable for the upper elementary years, but they also reflect changes in society and school…

Much contemporary research has demonstrated the multiple ways that sleep is important for child and adolescent development. This article reviews that research with an emphasis on how sleep parameters are related to school adjustment and achievement. Five areas of sleep research are reviewed to discern implications for practice with children using…

The early introduction of solids to infants is a risk factor associated with later health problems including allergies, overweight, and diabetes. The Infant Feeding Series (TIFS), a newly designed curriculum that promotes the appropriate transition to solids through parenting education and behavior change among low-income mothers, used the Theory…

The purposes of this study were to clarify how social problem-solving processes develop and to identify developmentally-sensitive intervention components for children's aggression. Elementary and junior-high school Japanese students (N = 1100) from urban public schools participated in the present investigation. Their alternative thinking skills,…

Major psychological theories of morality and motivation make the assumption that an inverse relationship exists between guilt and satisfaction. To the extent that feelings of guilt are linked to a particular motivational or moral stance, it is assumed that feelings of satisfaction are unlikely also be linked to that stance. Empirical findings in…

California has one of the latest kindergarten entry cutoff dates in the nation, December 2, which effectively allows children as young as four years, nine months to enter kindergarten. Proponents of moving the cutoff date to earlier in the year contend that children who enter kindergarten before age five are not developmentally mature enough yet…

Previous studies have suggested that typically developing 6-month-old infants are able to discriminate between small and large numerosities. However, discrimination between small numerosities in young infants is only possible when variables continuous with number (e.g. area or circumference) are confounded. In contrast, large number discrimination…
