| Abstract: | Develops a general behavior-regulation model of learned performance related to the equilibrium approach of W. Timberlake (1980) and W. Timberlake and J. Allison (1974). The model is based on 4 assumptions: (1) Both the instrumental and contingent responses are regulated with respect to their own set points; (2) these set points can be measured in a free baseline when both responses are relatively unconstrained and simultaneously available; (3) a reinforcement schedule can be seen as a constraint function that cross–couples the environmental effects of regulatory systems underlying the instrumental and contingent responses, thereby challenging their set points; and (4) molar behavior change under a schedule represents a compromise between the deviations from set points forced by the constraint function. These assumptions are translated into a set of coupled differential equations describing 2 regulatory systems related by a schedule. After providing an exact solution for this model, 2 special cases are derived as current alternative models of learned performance, those of J. Allison (see record 1976-23479-001) and J. R. Staddon (see record 1980-27259-001). The model is consistent in form with data from a variety of simple schedules. (53 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
