Table 2. Experiment 2.
Effects of chronic (5 day) administration of vehicle (V) and doses of 3-ISOPBC on seeking in Component 2 (C2) for alcohol (Alcohol Group) and a non-alcoholic beverage (Control Group) under the chained schedule of reinforcement. Baseline (BL) is the grand mean of the 3 days preceding each chronic condition.
