Effects of chronic nicotine administration on speed of processing in the 5-CSRTT under baseline conditions and during repeated PCP administration. Latencies to correct response are expressed as mean ± SEM. Bar graphs show binned averages from the 5 baseline days preceding any drug treatment and the 9 days of PCP-free pump treatment (left) and binned averages from the 5 days of saline injection during pump treatment and the 5 days of PCP administration during pump treatment (right). †p < 0.05, statistically significant Presence of Pump × Pump Content interaction. ###p < 0.001, statistically significant difference compared with performance after saline injections. Gray field indicates the period of pump treatment. ↑ indicates a PCP injection.
