Effects of cotinine on Delayed Match to Sample (DMTS) performance in monkeys. Fig 2A illustrates the dose-effect relationship for each delay in the DMTS task in 8 adult rhesus macaques, 15 min after the intramuscular administration of cotinine. Each bar represents the mean (% correct) ± SEM over 96 trials per session. The baseline (Vehicle) was determined from the average of all vehicle sessions run throughout the study. Inset (Fig 2B): the effect of cotinine on standard DMTS accuracy when the test was administered 24 h after dosing. *= significantly different (p<0.05 compared) to vehicle baseline levels of DMTS accuracy. + = p<0.07.
