1973 年，麦金托什报告了一种干扰效应，他称之为习得性不相关性，其中暴露于无条件刺激 (US) 和条件刺激 (CS) 的不相关 (CS/US) 呈现会干扰未来的巴甫洛夫条件反射。有人认为，习得的不相关性不存在特定的干扰效应；相反，干扰是独立的 CS 和 US 暴露效应 (CS + US) 的总和。我们回顾了之前关于这个问题的研究并报告了两个新的实验。我们的结论是，习得的不相关性是偶然学习和特定的习得的不相关性机制的结果。此外，甚至在之前的实验中用于支持 CS 和 US 暴露账户的“独立暴露控制”也为相关学习过程提供了支持。
In 1973 Mackintosh reported an interference effect that he called learned irrelevance in which exposure to uncorrelated (CS/US) presentation of the unconditional stimulus (US) and the conditioned stimulus (CS) interfered with future Pavlovian conditioning. It has been argued that there is no specific interference effect in learned irrelevance; rather the interference is the sum of independent CS and US exposure effects (CS + US). We review previous research on this question and report two new experiments. We conclude that learned irrelevance is a consequence of a contingency learning and a specific learned irrelevance mechanism. Moreover even the "independent exposure controls", used in previous experiments to support the CS and US exposure account, provide support for the correlation learning process.
