bred high alcohol-preferring (HAP-1 and HAP-2 replicates) mice and their low alcohol-preferring (LAP-1 and LAP-2 replicates) counterparts were examined, it was found that, as with the rat lines, HAP-1 and HAP-2 mice showed a significantly lesser CTA to sodium chloride than LAP-1 and LAP-2 mice (Chester et al. 2003). This highly consistent set of findings suggests that low sensitivity to some aversive effects of alcohol accompanies a tendency to prefer alcohol solutions.
