Methamphetamine CPP in adult rats in response to training with 0.5 mg/kg. for: 3 days with a post-test conducted one day after the last training session (3D + 1, n=10), 3 days with a 3 day delay before testing (3D + 3, n=10), or 5 days with a 3 day delay before testing (5D + 3, n=8). Data are presented as the amount of time spent in the methamphetamine-paired chamber during the post-test minus time spent in the methamphetamine-paired chamber during the pretest. Only the five-day training paradigm led to a significant change in preference over the pretest. *significantly different from 0 (P < 0.05). MA = methamphetamine
