ABSTRACT

Baseline logic serves as the foundation for all single subject research paradigms. That is, all single subject research designs are mere extensions or elaborations of the basic A-B paradigm. This chapter describes those single subject designs commonly referred to as "withdrawal" or "reversal" designs. The chapter discusses several alternative experimental designs. There are circumstances in educational and clinical settings that may preclude the use of more extensive experimental designs that require the repeated withdrawal of the independent variable. An A-B design was employed to evaluate the effects of the simple correction and overcorrection procedures on the frequency of the residents' stealing. The A-B design provides a framework for repeated measurement of a target behavior during baseline and intervention conditions. The primary advantage of the A-B-A design, when compared with the A-B design, is that it allows a functional analysis of behavior.
