“…To date, a range of behavioral sex research studies concerned with stimulus control have examined habituation to sexual stimuli (e.g., Koukounas & Over, 1993;Meuwissen & Over, 1990;O'Donohue & Plaud, 1994;Plaud, Gaither, Henderson, & Devitt, 1997), the respondent conditioning of sexual arousal to arbitrary stimuli (e.g., Langevin & Martin, 1975;Plaud & Martini, 1999;Rachman & Hodgson, 1968;Roche & Barnes, 1997), and the operant conditioning of sexual arousal (e.g., Rosen, Shapiro, & Schwartz, 1975;Schaefer & Colgan, 1977). As a result, a modest but relatively fruitful laboratory-based learning approach to sexual behavior has been developed.…”
