Effect of ethanol self-administration on choice behavior: money vs. socializing.
Volunteer chronic alcoholic subjects were exposed to a discrete-trail choice procedure within a residential research setting. Twelve daily trials occurred at 20 min intervals. In each trial a subject chose between 2 mutually exclusive options involving either receipt of money or the opportunity for socializing. The effect of ethanol self-administration was evaluated by requiring randomly over days that a subject consume either 8 drinks of orange juice or 8 drinks of ethanol (89.12 g ethanol total). For all 4 subjects, the mean rate of choosing socialization over money was significantly greater on sessions involving ethanol self-administration than on sessions involving orange juice self-administration.
