A handheld computer observation system was developed using Hewlett-Packard HP71B computers for recording and IBM-PCs for storing and analyzing data. Algorithims used in observing interactions between handicapped children and peers or teachers are described. Also described are behavior definitions, observer training and observation procedures, the…

A behavioral assessment procedure was evaluated with five children with severe/profound mental retardation who exhibited feeding problems of limited intake. Subjects were fed various types of foods. Results indicated each subject fit into one of four categories: (1) total food refusal, (2) food type selectivity, (3) food texture selectivity, or…

Parallels between subsistence foraging and scholarly information seeking are described in the context of the World Wide Web. Suggests that the prevailing information retrieval paradigm does not capture the complex of behavior and stimuli that drives scholars' quests for new ideas and insights. Research questions are suggested by extended use of…

Focuses on three issues raised by findings presented in preceding articles: (1) How do we continue the study and conceptualization of secure-base behavior? (2) How do we take into account the multiple-relationship context of attachment? and (3) How do we expand our conceptualization of attachment to include variations in individual adaptations and…

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…

Presents study results examining conditions in which children can apply a previously learned memorization strategy to new but analogous tasks. Concludes that strategy mastery during training is not sufficient. Reports that only subjects who use information about relations between procedures and results to construct generalizable knowledge are able…

A brief biographical sketch of Burrhus Frederick Skinner is offered, followed by a review of his impact on education and psychology. His research in radical behaviorism, his theoretical contributions, development of programed instruction techniques, token economies, and numerous inventions by himself and his proteges are summarized.

Discusses the history of the hierarchical epigenetic systems view as applied to human development and offers examples of its implementation. Notes the agreement by many authors that the multilevel systems view is the right model for developmental psychology in both human and animal studies. (BC)

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…

Methods of testing relatively complete (distributional) models of internal psychological processes are described. It is shown that there is a sufficient condition for additive models to imply this property of the likelihood ratio. Also discussed are the examination of hazard rate functions of component processes and change in cumulative…

Emphasis on technological precision and methodological sophistication in the field of applied behavior analysis has brought about a deemphasis of theoretical and philosophical concerns. For theoretical development of the field to move ahead, applied behavior analysts must develop the principles needed to describe ways of predicting and controlling…

There should not be an intentional reduction of the technological focus in applied behavior analysis research to expand the theoretical focus. The manner in which applied behavior analysis has beneficially affected the field of developmental disabilities services demonstrates how technologically related research plays a necessary role.

Monte Carlo methods were used to evaluate the degree to which canonical function and structure coefficients may be differentially sensitive to sampling error. For each of 64 research situations, 1,000 random samples were drawn. Both sets of coefficients were roughly equally influenced; some exceptions are noted. (SLD)

This response to Chandler et al. (EC 604 147) suggests that generalization of social competence training be viewed from both functional and topographical perspectives which have scientific and practice biases, respectively. The paper proposes a generalization-discrimination continuum along which behaviors may be placed for optimum utility. (DB)

Effects of response guided experimentation in applied behavior analysis on Type I error rates are explored. Data from T. A. Matyas and K. M. Greenwood (1990) suggest that, when visual inspection is combined with response guided experimentation, Type I error rates can be as high as 25%. (SLD)
