Mean AUC for LEW and F344 across all doses of acute NIC during experiment 1. “C” corresponds to control (no-drug) sessions, and “S” corresponds to sessions in which SAL was administered. An AUC value of 0.0 indicates exclusive choice for the smaller, immediate reinforce, and an AUC value of 1.0 indicates exclusive choice for the larger, delayed reinforcer. Note that data for each rat strain are collapsed across delay series. Error bars represent standard error of the mean. Asterisks represent a statistically significant difference from SAL (p < 0.05)
