The empirical law relating acquired drive strength, as measured by the latency of a hurdle-jump response, to UCS intensity and number of CS-UCS pairings was investigated. The effect on acquired drive strength of varying the intervals between successive CS-UCS pairings was also investigated. Ss were 150 male albino rats, 125-160 days old. The apparatus was the classically conditioned fear apparatus. Acquired drive strength was found to be curvillinearly related to UCS intensity and number of CS-UCS pairings when a 10 minute intertrial interval was used. The relationships were monotonic and hegatively accelerated. The effect of UCS intensity on acquired drive strength varied with the length of the intertrial interval. The findings of diverging functions relating UCS intensity to test trials support Spence's notion of multiplicative relationship between habit strength (sHr) and drive (d) in the determination of performance in aversive conditioning.
研究了通过跨栏跳跃反应潜伏期测量的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之间的经验法则。还研究了连续条件刺激-无条件刺激配对之间间隔变化对习得驱力强度的影响。实验对象为150只125 - 160日龄的雄性白化大鼠。实验仪器为经典条件恐惧装置。当使用10分钟的试验间隔时，发现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。这些关系是单调且负加速的。无条件刺激强度对习得驱力强度的影响随试验间隔长度而变化。将无条件刺激强度与测试试验联系起来的发散函数的研究结果支持了斯彭斯关于在厌恶条件作用中习惯强度（sHr）和驱力（d）之间的乘法关系在决定表现方面的观点。
