Table 1.

Mean and standard error of the mean (SEM) responses generated in each criterion and contributing to the Addiction-like Behavior Score (ALB) for: all rats; small suppressors; large suppressors; smallest 5 suppressors; and largest 5 suppressors. Once ranked from lowest to highest, rats ranking in the highest third in each criterion received one point towards their ALB score.
