Eighteen rats were trained to run in a straight alley under 24 hours of water deprivation. They were then submitted to six daily trials under successive and independent water deprivation conditions of 24, 36, 48, 60, and 72 hours. The fact that the HR of these animals increased up to 508 BPM with the length of deprivation, and that there was no drop in the performance for the 60 and 72 hours deprivation condition, would suggest that the relationship between performance and activation is sometimes monotonic and sometimes curvilinear, depending upon the nature of the task investigated.
