title: Reactivity to alcohol cues in alcoholics and non-alcoholics: implications for a stimulus control analysis of drinking.
abstract: The present study is an attempt to identify responses to alcohol-related stimuli which might differentiate alcoholics from non-alcoholics. The assumption was that alcoholics would be more reactive to alcohol cues because of prior conditioning history with respect to alcohol and drinking. Eight alcoholics in treatment were compared with ten non-alcoholic controls and two recovering alcoholics, using swallowing and salivation as the principal dependent measures. (The concordance of swallowing and salivation was validated using dental rolls with an independent group of ten alcoholics.) Five-minute "sniff-trials" were provided in which subjects smelled either cedar chips or their favorite alcoholic beverage, in a labelled container. Swallowing (salivation) and craving (desire to drink alcohol) were significantly elevated in alcohol-sniffing trials for alcoholics in treatment compared with non-alcoholics; cardiac rate and galvanic skin response duration were also elevated in alcoholics in treatment, though not significantly. Recovering alcoholics resembled alcoholics in treatment more closely than they resembled non-alcoholics. The data were examined in the context of conditioned withdrawal resembled non-alcoholics. The data were examined in the context of conditioned withdrawal and homeostatic protective mechanisms. Implications for the stimulus control analysis of drinking were discussed.
