Mean ± SEM trials completed to reach criterion, proportion correct trials, lever press reaction time (sec), trial omissions, and error subtypes (P: perseverative; R: regressive) during the reversal-learning phase in rats with adult-onset and adolescent-onset self-administration experience or passive saline or passive cocaine exposure. # p ≤ 0.05 compared to same treatment condition in the other age group; * p ≤ 0.05 compared to the age-matched rats passively receiving yoked-saline; + p ≤ 0.05 compared to age-matched rats self-administering cocaine and passively receiving yoked-saline; ^ p ≤ 0.05 compared to adult-onset rats overall.
