“…The manipulation of magnitude of reinforcement has been shown to impact a variety of outcomes including preference for work arrangements (Ward-Horner, Pittenger, Pace, & Fienup, 2014), the effects of noncontingent reinforcement (NCR; J. E. Carr, Bailey, Ecott, Lucker, & Weil, 1998), behavioral persistence (McComas, Hartman, & Jimenez, 2008), choice responding during play activities (Hoch, McComas, Johnson, Faranda, & Guenther, 2002), skill acquisition with differential reinforcement (Fiske et al, 2014), allocation of responding between problem behavior and mands for breaks (Peterson, Frieder, Smith, Quigley, & Van Norman, 2009), and reinforcer efficacy and preference during treatments for problem behavior (Trosclair-Lasserre, Lerman, Call, Addison, & Kodak, 2008). Although other dimensions of reinforcement (i.e., quality, Lee & Sturmey, 2006; delay to reinforcement, Muething et al, 2018) have been shown to affect communicative response variability, the current results are the first to have demonstrated such effects produced by magnitude of reinforcement.…”
