Deanna Kuhn's theory of informal argumentation (1991) evaluates arguments according to a theory/evidence model where subjects first articulate a theory and then must provide critical testing of alternatives on the basis of evidence. Using this model, Kuhn reports that many subjects fail to supply adequate evidence for their 'theories' and are often unable or unwilling to generate alternatives. In this paper an account of practical reasoning is provided that suggests an alternate interpretation for Kuhn's subjects' poor perfonnance. It is argued (...) that treating practical arguments as failed theoretical justifications causes Kuhn to misrepresent the contribution of many of her subjects' arguments. (shrink)

Determinism has long been a core assumption in many forms of behaviorism, including radical behaviorism. However, this assumption has been a stumbling block for many—both within and outside the field of radical behaviorism—resulting in misunderstanding and misrepresentation. The following paper provides a descriptive taxonomy of four kinds of determinism assumed or asserted in the radical behavioral literature. This taxonomy is intended to organize these deterministic positions, provide working definitions, and explore their implications. Through this work, it is hoped that behaviorists (...) and nonbehaviorists alike will possess a clearer understanding of determinism in behavioral analysis. (shrink)
