“…Laboratory analyses of renewal typically consist of three phases (baseline, treatment, and a renewal test). In the case of research using rat subjects, for example, a target behavior like lever pressing may be reinforced in the presence of one context (Context A) defined by unique exteroceptive (e.g., auditory, visual, olfactory, tactile, and/or social; e.g., Bouton et al, ; Browning & Shahan, ) and/or interoceptive (e.g., drug states, hunger level; Bouton, Kenney, & Rosengard, ; Schepers & Bouton, ) stimuli. Next, during treatment, lever pressing may be placed on extinction in the presence of a second, distinct set of contextual variables (Context B).…”
