title: Effect of taste aversion learning on ethanol self-administration.
abstract: Ethanol (EtOH) oral self-administration studies using rats have had inconsistent outcomes: studies in which rats are fluid deprived report decreasing EtOH intake over trials, whereas studies not employing fluid deprivation report increasing intake over trials. The present study supports the hypothesis that differential taste aversion learning may account for some of this discrepancy. This study indicates that taste aversion learning is maximized under fluid deprivation conditions and that "latent inhibition," i.e., exposure to non-intoxicating amounts of the EtOH solution prior to conditioning, reduces taste aversion learning. It is suggested that the effect of fluid deprivation on taste aversion resulting from EtOH self-administration may be at least in part due to the development of latent inhibition in non-deprived animals during initial exposure to the EtOH solution.
