Background: Research clearinghouses (CHs) seek to play an important role in identifying successful social programs and practices. The evidence-based policy movement has grown tremendously over the last few decades and has gotten institutionalized in the form of CHs in the US. CHs (1) specify standards for evaluating the quality of evidence from…

The concepts and paradigms "development", "evolution", and "developmental behavior genetics" target, in their statements, populations. The laws of genetics and evolution are supposed to apply to every single case in a population. It can be counted among the major contributions of Gottlieb (1992, 1995) to have pointed…

Molenaar's (2015) article concerns Developmental Systems Theory (DST) in relation to behavior genetics and he presents implications of DST for empirical research, especially the need for subject-specific studies. In this commentary, the article is discussed from a broader developmental science perspective, particularly regarded through the lens of…

Reports on a strategy of continuous measurement of the frequency of the same infant behavior over time, which was applied to measuring infant development in the prone position, namely, chin lifting, chest lifting, and a creeping response. (BD/BR)

An attempt was made to increase the competency skills of 44 male students in grades 7 to 9 through the Socratic teaching of the theory of security and independence, the behavioral practice of coping skills, or both. (Editor)

This review of 50 social validation research studies involving persons with handicaps concludes that social validation procedures are an appropriate and important component of applied behavior analysis. Discussed are methodological issues, social importance of effects, social significance of goals, social appropriateness of procedures, and…

This paper elucidates the implications of life-span developmental psychology for theory and method in the field of child development. Emphasis is given to three theoretical issues: (1) historical-evolutionary versus ontogenetic components of change, (2) the role of chronological age, and (3) continuity versus discontinuity in the description and…

Argues that the world view of contemporary behavior analysis, especially behavior analysis of child development, is contextualistic, not mechanistic. The history of behavior analysis is presented in a revised account that focuses on philosophic movements. Contextualism of behavior analysis is contrasted with mechanism with respect to five core…

The present experiment attempts to manipulate the saliency of subjects' recollection of their behavior by giving them a task to do which requires them to generate cognitions resulting in one of two sets of cognitive associations. (Author)

Cluster analysis procedures used in a study of 43 stutterers (ages 3-9) identified 14 associated speech and nonspeech behaviors and speech disfluency types, three related indices (sound prolongation, nonspeech behavior, behavioral variety), and five clusters of young stutterers. Behavioral differences reflected differences in the youngsters'…

Presents an overview of the topics of planning and control to provide a context for the articles in this issue of the journal. Considers development across the life span, subgroup variations, and correlates. Also explores potential linkages between planning and control. (MM)

Discusses the use of new statistical procedures in a study of the enduring effects of prenatal alcohol exposure upon the neurobehavioral development of some 500 children born in 1975-76. Explains how the Partial Least Squares (PLS) methodology can summarize the data powerfully while avoiding familiar inferential pitfalls. (MDM)

Developmental studies have primarily focused on what takes place within the confines of a given interpersonal system (first order development). What has been neglected is second order development, the interpersonal communication that alters the system itself. From this particular developmental perspective, a model can be used that illustrates and…

This article examines research methodology, dependent measures, and programmatic variables used to analyze the effects of preschool integration of children with disabilities. Analysis provides support for the benefits of preschool integration with respect to social and other behavioral outcomes, though not for developmental outcomes over time.…
