通过改变条件刺激和非条件刺激之间的偶然性对自形反应习得的影响，探讨了在实验间隔内改变无信号刺激的频率。未发出信号的USs的加入对获取速度的影响与大规模试验的影响相当。这些操作的影响可以从它们对平均CS传达给受试者的关于下一个美国时间的信息量（比特数）的影响来理解。获取前增强的CSs数量与CS的信息含量呈负相关。
The effects of altering the contingency between the conditioned stimulus (CS) and the unconditioned stimulus (US) on the acquisition of autoshaped responding was investigated by changing the frequency of unsignaled USs during the intertrial interval. The addition of the unsignaled USs had an effect on acquisition speed comparable with that of massing trials. The effects of these manipulations can be understood in terms of their effect on the amount of information (number of bits) that the average CS conveys to the subject about the timing of the next US. The number of reinforced CSs prior to acquisition is inversely related to the information content of the CS.
