The evidence-base of psychosocial treatment outcome studies for depressed youth conducted since 1998 is examined. All studies for depressed children meet Nathan and Gorman's (2002) criteria for Type 2 studies whereas the adolescent protocols meet criteria for both Type 1 and Type 2 studies. Based on the Task Force on the Promotion and…

This paper is an introduction to behavioral genetics for researchers and practitioners in language development and disorders. It identifies essential concepts and applies behavioral genetic research to the language sciences. It suggests that more complex questions may be successfully addressed through behavioral genetic paradigms. Research needs…

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 article discusses problems inherent in the analysis of automatically reinforced behaviors, which are behaviors that are maintained by operant mechanisms independent of the social environment. Four classes of treatment that are compatible with automatic reinforcement are reviewed, including manipulations of establishing operations, sensory…

This paper examines the influence of Norman Geschwind's model of connectionism, in which complex functions are built up by connecting primary areas in the brain, and notes his studies of the effects of disconnection on dyslexic individuals. Connectionist-based behavioral studies are reviewed, focusing on intracortical association connections and…

A review of the January 1993 issue of the "Journal of the Experimental Analysis of Behavior" concludes that behavioral interventions produce collateral effects, but predicting those effects in applied work is complicated because of verbal and instructional influences and because of interactions among reinforcer types. (JDD)

A review of 158 applied behavior analysis studies with children as subjects, published in the "Journal of Applied Behavior Analysis" between 1980 and 1990, found that (1) 16% measured the accuracy of independent variable implementation, and (2) two-thirds did not operationally define components of the independent variable. Specific recommendations…

This literature review addresses the technical adequacy of time sampling observation systems, which is fundamental to ensuring the generalizability of data obtained from behavioral observation. Investigations comparing partial interval, whole interval, and momentary time sampling have yielded consistent results. These suggest that duration of…

A major debate exists in the neuropsychology community concerning whether case study is preferable to group study of brain-damaged patients. So far, the discussion has been limited to the advantages and disadvantages of both methods, with the assumption that neurolinguists pursue a single goal attainable by one or the other method. Practical…

A review of research on state behavior among students with profound disabilities is presented, and a model depicting interactions of state with endogenous and exogenous variables is offered. Applications of the model are illustrated through four case studies displaying different state patterns. Measurable attributes of state having implications…

An overview of educational evaluation literature is followed by summaries of research on both the perceptions of school principals about their awareness and use of evaluation in decision-making and their evaluation behavior. New lines of research on evaluation for decision-making as a learning process are offered. (MLF)

This paper considers key properties of behavioral phenotypes of mental retardation syndromes, including within-syndrome variability and between-syndrome similarities and qualitative differences. The "new genetics" research requires combining data from three strategies: (1) a psychiatric approach, (2) psychometric methods, and (3) syndrome-specific…

This article reviews 66 studies which used applied behavior analysis to change the behaviors of students with visual disabilities. It documents the participants, targeted behaviors, procedures used, outcomes, and follow-up. The article offers recommendations for future researchers on the selection of subjects, target behaviors, appropriate…

This review of research discusses how children with autism may acquire equivalence classes after learning to supply a common oral name to each stimulus in a potential class. A proposed methodology for researching referent naming and class formation, analysis of stimulus classes, and generalization is offered. (CR)

Current status and new developments in behavioral assessment for clinicians and researchers are discussed. The field of behavioral assessment has attained a recognizable identity in recent years. Behavioral assessment can be defined as the identification of meaningful response units and their controlling variables for the purposes of…
