Alcohol seeking operant responses in Component 2 of the chained schedule under conditions of alcohol or water availability in Component 3. Alcohol seeking responses shown are the number of left lever responses (right panel) and the latency to respond (left panel) on the left lever during the FI 10’ FT 20’ schedule in Component 2. Data shown are mean ±SEM for the group for the last 5 days of alcohol availability prior to extinction, and the first 5 days and last 5 days of extinction. * indicates a significant (p<0.05) difference from the alcohol condition and ** indicates significant (p<0.05) differences from both alcohol and the first 5 days of extinction.
