“…If, however, the difference between target and control responding is small, or control responding exceeds target responding, then variables other than the prior reinforcement history are implicated in determining the latter. Indeed, the amount of human control responding during the resurgence test equaled or exceeded target responding in several of the experiments (e.g., Bolívar, Cox, Barlow, & Dallery, 2017;Bruzek, Thompson, & Peters, 2009;Cox, Bolívar, & Barlow, 2018;Sweeney & Shahan, 2016). Before considering the interpretation of the presence or absence of control responding, findings from experiments in which a control response was used should be considered to provide a concrete context for evaluating its use and interpretation.…”
