This paper presents the empirical basis for the phenomena known as stimulus overselectivity. Stimulus overselectivity involves responding on the basis of a restricted range of elements or features that are discriminative for reinforcement. The manner in which such a response pattern impedes the skill acquisition in children is identified. A…

Methods and outcomes from functional behavioral assessment have been researched widely over the past twenty-five years. However, several important research questions have yet to be examined sufficiently. This quantitative review of developmental disability research aims to make comparisons of different functional behavioral assessment…

The American government set new standards mandating States to demonstrate adequate yearly progress for all students with the inception of the No Child Left Behind Act. To be eligible for the more recent Race to the Top funds, states must show, in part, a commitment to "building data systems that measure student growth and success, and inform…

Precision teaching emerged from O.R. Lindsley's pristine application of Skinner's natural science of behavior, with a focus on response rate measurement and free operant procedures. When applied with human learners in instructional settings, these first principles led to a series of developments framed in this paper as four kinds of ceilings that…

This paper describes materials designed for classroom projects on stimulus generalization and peak shift. A computer program (originally written in QuickBASIC) is used for data collection and a Microsoft Excel file with macros organizes the raw data on a spreadsheet and creates generalization gradients. The program is designed for use with human…

In order to maximize the learning of skills, it is crucial that the most powerful reinforcement be used. Research describes several different methods of reinforcement preference assessments, including forced choice, free-operant, and multiple stimulus array procedures. Researchers have also tested many variables to determine their potential impact…

The effectiveness of within-session and across-session variations of a progressive time delay procedure for teaching sight words was evaluated for five participants with cognitive delays. Participants were exposed to five target stimuli using two variations of progressive time delay procedures in an alternating treatments design, followed by the…

The assessment of child sexual abuse has largely been ignored by behavior analysts, although behavior analytic theory and methodology, if applied, likely would advance the field. Three classic cases demonstrate historic errors that might have been avoided, had a behaviorally based approach been employed. Functional analytic interpretations are…
