A short prime presentation has been shown to provide a greater priming magnitude, whereas a longer prime presentation results in a lower priming magnitude. In Experiment 1, we attempted to replicate the decrease of priming using word stimuli. Words were presented in both prime and test sessions, and participants judged whether each stimulus was natural or manmade. In Experiment 2, we employed a cross-domain priming paradigm to assess the impact of prime duration on non-perceptual processes. Pictures were presented in prime sessions, and their semantically matched words were presented in test sessions. We did not observe a significant decrease in priming in Experiment 1. However, we found that 2000 ms of prime exposure led to weaker cross-domain priming when compared with 250 ms of the exposure in Experiment 2. The results suggest that the longer presentation of pictures causes a non-perceptual adaptation effect. This effect may occur at conceptual, linguistic, and/or response-related levels.
研究表明，简短的启动刺激呈现会产生更大的启动效应量，而较长的启动刺激呈现则会导致较低的启动效应量。在实验1中，我们试图使用单词刺激来复制启动效应的降低。单词在启动和测试阶段都有呈现，参与者判断每个刺激是自然的还是人造的。在实验2中，我们采用了跨领域启动范式来评估启动持续时间对非感知过程的影响。图片在启动阶段呈现，其语义匹配的单词在测试阶段呈现。我们在实验1中没有观察到启动效应的显著降低。然而，我们发现，与实验2中250毫秒的暴露时间相比，2000毫秒的启动暴露导致跨领域启动效应较弱。结果表明，图片较长时间的呈现会产生非感知适应效应。这种效应可能发生在概念、语言和/或反应相关的层面。
