重复启动对时序知觉的影响

The Influence of Repetition Priming on Temporal Order Perception

在时序判断任务中，重复启动导致被试把启动的靶刺激知觉为先出现的。知觉加工增强观和决策反应偏向观都试图解释其机制，但仍存在争议。本研究采用图形材料，通过三个实验系统考察了重复启动对时序知觉的影响。实验结果显示，启动和指导语都具有显著效应。这说明，重复启动对时序知觉的影响涉及知觉加工和决策水平两个方面。实验还首次发现，在启动的靶刺激先出现时发生了重复启动效应的反转。最后，研究提出了双加工表征匹配调节假说，用以综合解释目前的研究结果。

There are two competing views that explain the influence of repetition priming on temporal order perception. One perspective assumes an enhanced perceptual processing; the other suggests a decisional response bias. Burnham et al. (2006) found that repetition priming caused a primed word to be perceived as having occurred earlier， and that a decisional response bias caused subjects to guess the primed word as the correct response in a temporal order judgment task.
