Objective The delayed-response task based on the Wisconsin General Testing Apparatus (WGTA) is commonly used to evaluate the ability of learning and memory in nonhuman primates. Because the task may be influenced by a number of factors, how to set and standardize the parameters during the training and evaluation stage is of great significance and value for obtaining appropriate results of learning and memory ability. Methods In this study, 8~9 years old male cynomolgus macaques (Macaca fascicularis) were tested with the modified WGTA. We evaluated the influence of experimental factors such as the times of training, frequency of evaluation, interval time of evaluation, delayed time and number of stimulus trays on the results of learning and memory ability in the macaques by investigating the correct rates of food acquiring. Results The correct rate of food acquiring of the cynomolgus macaques was unstable and significantly decreased when the times of training was less than 10 during the training stage. The frequency of evaluation had less effect on the correct rate on the basis of enough training. The correct rate of food acquiring was still above 65% with a 3-month interval after training. However, the increase of delayed time led to significant decrease of the correct rate in some macaques. In addtion, more than 3 stimulus trays also resulted in a low correct rate in general less than 65%. Conclusions Reasonable designing of the experimental parameters during the training and evaluation stage is important for determining the learning and memory ability in nonhuman primates.
