在 4 个实验中，受试者将视觉上呈现的目标词分类为令人愉快的-不愉快的词或男性-女性的名字。主要词与目标的含义相似（一致）或不相似（不一致）。短暂的主词持续时间（17、33 或 50 毫秒）以及前掩蔽和后掩蔽使大多数受试者无法感知其物理和语义属性。通过将反应潜伏期限制在反应窗口（比受试者通常反应更早的狭窄时间带）内，这些实验始终产生阈下启动效应，这表明不一致启动试验的错误率高于一致启动试验。通过使用 A. G. Greenwald、M. R. Klinger 和 E. S. Schuh (1995) 的方法将启动幅度作为启动可感知性的回归函数进行分析，证实了这一结论。每个实验的数据都通过了证明无意识认知的显着截距标准。
In 4 experiments, subjects classified visually presented target words as pleasant-unpleasant words or male-female first names. Prime words were similar (congruent) or dissimilar (incongruent) in meaning to targets. Brief duration of prime words (17, 33, or 50 ms), along with pre- and postmasking, prevented most subjects from perceiving their physical and semantic properties. By constraining response latencies to fall within a response window-a narrow time band that occurred earlier than subjects would ordinarily respond-these experiments consistently produced subliminal priming effects, indicated by greater error rates for incongruent than congruent priming trials. This conclusion was confirmed by analyzing magnitude of priming as a regression function of prime perceptibility using the method of A. G. Greenwald, M. R. Klinger, and E. S. Schuh (1995). The data of each experiment passed their significant-intercept criterion for demonstrating unconscious cognition.
