“…Consistent with this prediction, resurgence is reduced by using very lean reinforcement rates during the response elimination phase (Leitenberg, Rawson, & Mulick, 1975; Sweeney & Shahan, 2013a). Resurgence (defined as an increase in responding from Phase 2 to testing) is also reduced by using schedules that are “thinned” from high rates to low rates across Phase 2 (Schepers & Bouton, 2015; Winterbauer & Bouton, 2012), although thinning itself can produce an increase in R1 responding (termed “early resurgence” by Winterbauer & Bouton, 2012). However, a reverse thinning procedure in which reinforcement rates start the phase at a lean rate and then increase during training also weakens resurgence (Bouton & Schepers 2014; Schepers & Bouton, 2015).…”
