The form of the empirical law relating acquired drive strength to UCS intensity and number of CS-UCS pairings was investigated in two experiments using 120 and 30 male albino rats, respectively. Strength of UCS was varied at a broad range of intensities. Controls were introduced to prevent the intrusion of competing crouching responses (R1) on the measurement of response strength (R2). Acquired drive strength was found to be curvilinearly related to UCS intensity and number of CS-UCS pairings during conditioning. The relationship was monotonic and negatively accelerated. Habit strength, or sHr, was found to be jointly determined by UCS intensity (D) and number of CS-UCS pairings during aversive conditioning. These results were contrasted with findings for the instrumental appetitive learning case of Hull's system, where it has been shown that sHr and D are independent and interact in a multiplicative fashion in their effect on performance. An historical review of acquired drive experiments was also presented.
在两项实验中分别使用120只和30只雄性白化大鼠，对将习得驱力强度与无条件刺激强度及条件刺激 - 无条件刺激配对次数相关联的经验法则形式进行了研究。无条件刺激的强度在广泛的范围内变化。引入了对照以防止竞争性蹲伏反应（R1）干扰反应强度（R2）的测量。发现在条件作用期间，习得驱力强度与无条件刺激强度及条件刺激 - 无条件刺激配对次数呈曲线相关。这种关系是单调且负加速的。习惯强度，即sHr，被发现是由厌恶条件作用期间的无条件刺激强度（D）和条件刺激 - 无条件刺激配对次数共同决定的。这些结果与赫尔系统的工具性食欲学习案例的研究结果形成对比，在该案例中已表明sHr和D是独立的，并且在对表现的影响上以乘法方式相互作用。还对习得驱力实验进行了历史回顾。
