Coherence and the merging of relational classes in self-organizing networks: Extending Relational Density Theory

Analyzing the Functional Interdependence of Verbal Behavior with Multiaxial Radar Charts

The functional analysis of complex verbal behavior requires an evaluation of topographically similar responses under multiple sources of control. Traditional graphical displays of behavior were designed to show the manipulation of isolated controlling variables and may not be amenable to displaying the multidimensional properties of complex behavior. Researchers have recently demonstrated the use of multiaxial radar charts for comparing the functional performance of biological systems. Here we extend the use of multidimensional analyses to compare the relative performance distributions of verbal behavior across four potential controlling variables. First, we provide a conceptual analysis of intraverbal and extraverbal control as continua along which stimuli range from formal to thematic and explain how the intersection of these stimulus fields creates a radar chart for multidimensional analysis. Then we demonstrate how data may be gathered through a verbal operant experimental analysis. We employed repeated measures to map the conditioning history of a child with autism spectrum disorder across 2 years of early intensive behavioral intervention and analyzed the results using shape descriptors for quantitative comparisons. We also compared the polygonal language profiles of children with autism against that of a neurotypical peer. Extending a multidimensional analysis to the field of verbal behavior provides the basis for a language growth chart that researchers and clinicians can use to monitor language acquisition over time. We discuss the use of radar charts as a framework for understanding the interdependence of verbal operants and suggest their use for complex analyses of complex verbal behavior.

Relational Behavior and ACT: A Dynamic Relationship

Acceptance and commitment therapy (ACT) and its counterpart, relational frame theory (RFT), represent emerging areas of research and professional interest for behavior analysts. We extend traditional RFT approaches by emphasizing relational framing as a dynamic pattern of behavior with implications for ACT-based strategies implemented by behavior analysts in practice and in research. We borrow from emerging approaches within affective dynamics, relational density theory, and the hyper-dimensional multilevel model to develop some immediate considerations for practitioners. We then extend an approach grounded in relational dynamics to the six core processes of the ACT hexaflex not only to influence negative affective patterns of relational behavior but also to promote greater psychological flexibility and well-being. Finally, we turn this account inward to discuss our own rigidity as a field and the necessity to engage more flexibly with our own science, ultimately to improve the lives of clients whom we serve.
