人类巴甫洛夫条件反射研究的最新进展表明，条件反应（CR）的强度不仅受到连接条件刺激（CS）和非条件刺激（UCS）的联想过程的影响，而且还受到导致个体重新评估UCS本身的过程的影响。后一种过程通常会导致CR强度的剧烈变化，而与CS-UCS偶然性的任何经验无关。本文讨论了在人类受试者中影响UCS重估的一些方法，并讨论了它们对后天恐惧的条件反射模型的影响。
Recent developments in the study of Pavlovian conditioning in humans have suggested that the strength of a conditioned response (CR) is affected not only by associative processes that link the conditioned stimulus (CS) with the unconditioned stimulus (UCS), but also by processes which lead the individual to revalue the UCS itself. These latter processes can frequently lead to dramatic changes in CR strength independently of any experience with the CS-UCS contingency. This paper discusses a number of ways in which UCS revaluation can be effected in human subjects, and discusses their implications for conditioning models of acquired fears.
