Do Pavlovian Processes Really Mediate Behavioral Momentum? Some Conflicting Issues

Overview

According to the behavioral momentum theory of response strength (Nevin et al., Journal of the Experimental Analysis of Behavior, 53, 359–379, 1990 ), steady-state responding reflects the contingency between a response and a reinforcer (response–reinforcer relationship), whereas behavior’s resistance to change is mediated by a contingency between a stimulus and the reinforcer (stimulus–reinforcer relationship). It is further presumed in this theory that a Pavlovian conditioned stimulus (CS)–unconditioned stimulus (US) contingency overlaps with the discriminative stimulus (SD), signaling a primary reinforcer (SR+) within the 3-term contingency (SD: response [R]–SR+). The mere arranging of a stimulus–reinforcer relation in an operant preparation, however, does not necessarily imply that the resulting behavioral process is Pavlovian. This article questions how important such Pavlovian CS–SR+ relations really are in governing operant behavior and its resistance to change in view of evidence from the operant and Pavlovian literatures showing dissociation between Pavlovian and operant stimulus control. To this end, we highlight studies published in the Pavlovian associative literature (Holman and Mackintosh, The Quarterly Journal of Experimental Psychology Section B: Comparative and Physiological Psychology, 33, 21–31, 1981 ; Rescorla, Current Directions in Psychological Science, 1, 66–70, 1992b ) as well as at least 1 seldom-cited study published in the Journal of the Experimental Analysis of Behavior (Marcucella, Journal of the Experimental Analysis of Behavior, 36, 51–60, 1981 ) supporting the view that CS relations embedded in the 3-term operant contingency can act independently of the discriminative stimulus functions of the SD. These CS relations appear to be neither necessary nor sufficient for sustaining operant discriminative control. Pavlovian relations are likely to be artifacts of operant conditioning—not causal mediators. It is suggested that continued and excessive focus on Pavlovian processes that only have meager influence on operant behavior in general, and behavioral momentum more specifically, will likely be an empirical cul-de-sac for improvement of behavioral management for addiction relapse and other behavioral disorders.
