Systematic failure to perform exclusion (making a response that opposes the participant's natural inclinations) for briefly displayed, masked words has been interpreted as evidence of unconscious perception. The present study required participants to make a forced-choice exclusion after viewing masked word targets. The forced-choice exclusion task was properly performed in all experiments, in contrast to previous studies that have utilized stem-completion as a dependent variable. The exclusion failure effects interpreted as unconscious perception in earlier studies appear to be caused by an insensitive dependent variable (stem-completion) rather than unconscious perception.
对于短暂呈现、被掩盖的词语，系统性地未能执行排除任务（做出与参与者自然倾向相反的反应）被解释为无意识感知的证据。本研究要求参与者在观看被掩盖的词语目标后进行强制选择排除。与之前使用词干补全作为因变量的研究相比，强制选择排除任务在所有实验中都得到了正确执行。早期研究中被解释为无意识感知的排除失败效应似乎是由不敏感的因变量（词干补全）而非无意识感知导致的。
