Asbury and Wai ("Journal of School Choice," 2019) perform a valuable service by summarizing much available behavior--genetic research on academic achievement. However they consider that no specific policies stem from the research body at this time. Here we do propose a policy based on some of our research using twins, namely that…

In this four-investigation Monte Carlo simulation study, we examined the properties of nonparametric randomization and permutation statistical tests applied to single-case ABAB...AB and alternating treatment designs based on either systematically alternating or randomly determined phase assignments. Contrary to previous admonitions, when…

The time-series process postulated is a more general form of the integrated moving average model than for which estimation and testing procedures were formerly available. (Author)

Presents a general class of single-case statistical procedures derived from previously developed nonparametric randomization tests. Designs are illustrated that focus on the general and comparative effectiveness of alternative interventions, multiple units with differentiable characteristics, and multiple outcome measures. Provides operational…

Selecting a statistical framework for a behavioral study has profoundly different results than does a linguistically framed research strategy. The linguistic strategy overcomes many limitations inherent in statistical strategies and offers more meaningful results. Inferential statistical studies often discuss how the findings "explain" the results…

Some of the distinguishing features associated with behavioral prevention methodology are discussed. Behaviorists for Social Action have already implicitly identified target populations for preventive interventions, and the two distinct populations which have been identified can form the focus of preventive endeavors. The dissimilar populations…

Three kindergartens and one prekindergarten, totaling 213 children, participated in a Behavior Modification program during the 1971-72 school year. A research assistant in each location worked directly with the teacher in measuring and evaluating teaching methods and in developing alternative procedures as needed to teach the same skills or…
