Figure 3. Effort Discounting.

Figure 3

(A) Mean ± SEM percent high reward (HR) choices as a function of increasing barrier heights 15, 20, 25, and 30 cm before and after treatment with either 2 d of 250 mg/kg PCPA (250 PCPA) or 2 d of 500 mg/kg (500 PCPA) or 2d of saline (SAL). There was no effect of PCPA treatment on effort discounting, all groups chose similarly. (B) Mean ± SEM session duration in minutes. 250 PCPA finished sessions faster than the SAL, whereas 500 PCPA finished sessions more slowly than SAL. ** Different from SAL, p<0.01.
