Unpronounceable strings of 4 consonants (conditioned stimuli: CSs) were consistently followed by familiar words belonging to 1 of 2 opposed semantic categories (unconditioned stimuli: USs). Conditioning, in the form of greater accuracy in rapidly classifying USs into their categories, was found when visually imperceptible (to most subjects) CSs occupied ≥58 ms of a 75-ms CS-US interval. When clearly visible CSs were presented in a 375 ms CS-US interval, conditioning was strongly correlated with measures of contingency awareness, and did not occur in the absence of that awareness. These experiments delineated 2 forms of conditioning: Unconscious conditioning occurred with a brief CS-US interval, with an effectively masked conditioned stimulus (CS), and with no reportable knowledge of the contingent CS-US relation. Conscious conditioning occurred with a substantially longer CS-US interval, a perceptible CS, and with subjects' reportable knowledge of the contingent CS-US relation. (PsycINFO Database Record

无意识条件：证明存在和与有意识条件不同。

带有4个辅音的不可发音的字符串（条件刺激：CSs）后面紧跟着属于2个相对语义类别（非条件刺激：USs）中的1个的熟悉单词。当以视觉上无法察觉的方式（对大多数受试者）CS占据75毫秒CS-US间隔的≥58毫秒时，发现了以更快的准确度将美国迅速分类到其类别中的条件。当在375毫秒CS-US间隔内出现清晰可见的CS时，条件与应变意识的度量高度相关，在没有该意识的情况下不会发生。这些实验描述了2种形式的调节：无意识调节以短暂的CS-US间隔，有效掩盖的调节刺激（CS）发生，并且没有可报告的CS-US关系知识。意识调理发生的时间较长，CS-US间隔较长，CS可感知，并且受试者应报告的或有CS-US关系知识。（PsycINFO数据库记录
