Some Dimensions of Mand Variability and Implications for Research and Practice.

Abstract

Since Skinner's conceptualization of the mand, applied behavior analysis researchers have used the concept to develop stimulus control transfer procedures effective for addressing manding deficits. More recently, researchers have explored the clinical utility of reinforcing mand variability during mand training and functional communication training. However, limitations in the conceptual analysis of mand variability may have limited the kinds of questions addressed in this research and our understanding of the findings. The current article reconceptualizes mand variability as consisting of eight distinct dimensions and provides operational definitions of the dimensions that may be useful for more precisely characterizing the effects of reinforcement on mand variability in future research. The article concludes with a brief discussion of potential clinical and research implications.
