Habituation of electrodermal reactivity to visual alcohol stimuli in alcoholics

This study address the question of cued reactivity in alcoholics. Twenty alcoholic in-patients and 20 control subjects were presented with repeated exposures to a alcohol-related (A) and a neutral (B) slide, in either an ABA or BAB sequence. Skin Conductance Level (SCL) and Skin Conductance Responses (SCR) were recorded. Alcohol-dependent subjects showed increased SCR compared to the control subjects. This was, however, independent of whether the presented stimuli were alcohol-related or neutral. Thus, the results did not support the hypothesis of cued reactivity, but point to a nonspecific hyper-reactivity in alcohol-dependent subjects. The results are discussed in relation to risk-factors for alcoholism and relapse.
