The impact of functional class and depressive symptomatology on rule-based insensitivity

Rule-governed behavior (RGB) is important for accounting for complex human behavior, as well as informing clinical practice. In line with Relational Frame Theory, RGB is divided into functional classes including pliance, which is rule-following under the control of apparent arbitrary social consequences, and tracking, which is rule-following under the control of apparent natural non-arbitrary consequences. In theory, pliance should produce lower levels of contingency sensitivity compared to tracking, but how this effect relates to nonclinical populations is unclear. This study (n = 134) tested the relationship between contingency sensitivity in pliance and tracking through a Matching-to-Sample task, while incorporating a measure of depressive symptomatology to test if a distinction in insensitivity would be seen in nondepressed participants. Results indicated that pliance was associated with lower levels of contingency sensitivity relative to tracking overall, and that depressive symptomatology did not influence this. Results are discussed in relation to prior inconsistencies in the experimental literature on RGB, and potential methods for operationalizing pliance in experimental settings.
