Abstract : In the present study, a Serial Probe Recognition (SPR) task was evaluated as an environmental enrichment device for nonhuman primates. Twenty-one rhesus monkeys were assigned to two experimental groups, one group male (n=15) and one group female (n=6). Urinary cortisol levels, which correlate positively with stress, were measured to determine the effectiveness SPR as an environmental enrichment device, with baseline measurements taken before the onset of the task, and experimental measurements taken during SPR training. Results showed that cortisol levels were significantly higher during the SPR condition than during the baseline condition.
