| Abstract: | An approach to a functional analysis of delusional speech and hallucinatory behavior is described and discussed using concepts found in Goldiamond's (1975a and 1984) nonlinear contingency analysis and Skinner's Verbal Behavior (1957). This synthesis draws upon and concords with research from the animal laboratory, with the extensive experimental literatures on stimulus control and signal detection theory, and with our own clinical experiences.In this formulation, delusional speech and hallucinatory behavior are viewed as successful operants. Accordingly, we argue that such behaviors can be considered adaptive and rational, rather than maladaptive and irrational, when analyzed within a model of consequential governance that includes alternative sets of contingencies. Several clinical examples are offered to illustrate both analytic procedures and the design of systemic treatment programs based upon a behavioral contingency analysis derived from a natural science of behavior. Throughout, we emphasize the consequential governance of these clinically important classes of behavior, in contrast to other approaches which suggest formal similarities to operant verbal behavior but largely ignore the role of consequential contingencies. |
