Effect of instructions and feedback on blood alcohol level discrimination training in nonalcoholic drinkers

Investigated whether nonalcoholic drinkers can be trained to discriminate their blood alcohol levels (BAL) on the basis of internal cues. 72 male undergraduates classified as heavy drinkers came to the laboratory for 3 consecutive sessions, each consisting of 5 BAL estimation trials. The 2 manipulated independent variables factorially combined were beverage sequence and administration of BAL feedback. All Ss were told that they would receive mixed drinks containing vodka and tonic on each day, and all Ss received alcohol on Day 1. On Day 2, half of the Ss received alcohol and half received tonic alone; similarly, half of the Ss in each of these groups received either alcohol or tonic on Day 3. No S received BAL feedback on Day 1, and one-third of Ss did not receive feedback on Days 2 and 3. The remaining Ss received feedback on Day 2; half of the latter Ss also received feedback on Day 3, and half did not. Ss did not learn to discriminate their BAL on the basis of internal cues. Results are discussed in reference to the utility of BAL discrimination training in alcoholism prevention programs. (24 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
