Mean (±1 SEM) accuracy expressed as percent correct matches after MCAM or morphine (1a) and mean (±1 SEM) number of trials completed out of 100 possible after MCAM (0.32 mg/kg) or morphine (0.32–5.6 mg/kg; 1b) for five monkeys responding under a delayed matching-to-sample task. Abscissae: delay in seconds between the sample and comparison components (1a) and dose in mg/kg body weight (1b). Filled symbols denote statistical significance (p<0.05) compared with saline. The shaded region denotes the 95% CI for saline.
