These plots compare BtwPR-seeking BP and WinPR BPs across reinforcer type (cocaine or water) in experiment 2. a Rats emitted a greater amount of effort to gain access to one infusion of 1.0 mg/kg of cocaine (as measured by the within-session breakpoints) compared to the amount of effort to gain access to a period of cocaine SA (as measured by the between-session breakpoints). b Rats emitted greater amount of effort to gain access to a period of water reinforcement (as measured by the between-session breakpoints) compared to the amount of effort for one presentation of 0.l mL of water (as measured by the within-session breakpoints). *p<0.05 indicate that the BtwPR BP is significantly different from the WinPR BP.
