aNumber of days Low WIN (0.2 mg/kg) IP, High WIN (1.2 mg/kg) IP or vehicle IP rats remained in current phase of training before advancing to next phase. Reinforcers earned: bSingle day of phase 1; cAverage over first 6 days in phases 2 and 5; dAverage over first 3 days in phases 3–4. eAccuracy across delays on first day of training in phases 4–5. *p < 0.05, High WIN vs. VEH.
