In order to establish a secondary drive based on thirst, 16 male albino rats were deprived of water for 23 hours per day for 14 days in square cages. At the end of each 23-hour period, the Ss were placed in triangular cages with free access to water for 1/2 hour followed by 1/2 hour in a circular cage with no water available. On day 15 the Ss were divided into two groups following satiation in the triangular cage. The control Ss were placed in the circular cages with water present for the first time, and experimental Ss were placed in the square cages with water present for the first time. During this 1/2-hour period the experimental Ss drank significantly more than the control Ss which indicated the presence of thirst fear in the experimental group.
为了建立基于口渴的二级驱力，16只雄性白化大鼠被置于方形笼中，每天缺水23小时，持续14天。在每个23小时时段结束时，将实验对象置于三角笼中，可自由饮水半小时，随后置于无水的圆形笼中半小时。在第15天，实验对象在三角笼中饱足后被分为两组。对照组实验对象首次被置于有水的圆形笼中，实验组实验对象首次被置于有水的方形笼中。在这半小时期间，实验组实验对象的饮水量显著多于对照组，这表明实验组存在口渴恐惧。
