However, in order to determine if and how the antecedent event influences subsequent behaviors, researchers must control for or measure all four terms of the behavioral interaction, ruling out the role of the discriminative stimulus and the maintaining consequence in behavior change.

Examples of functions that have been studied include rate of responding (Barnes & Keenan, 1993), discriminative stimulus control (Lazar & Kotlarchyk, 1986), instructional control (McGuigan & Keenan, 2002), conditional discriminative control (Wulfert & Hayes, 1988), contextual control (Kohlenberg, Hayes, & Hayes, 1991), and eliciting functions (Dougher, Auguston, Markham, Greenway, & Wulfert, 1994).
