目标探测范式中颜色类别知觉效应的产生机制探讨

通过改进目标探测范式,在目标探测任务过程中融入发声干扰任务,以考察颜色类别知觉效应是否是一种知觉现象.实验结果获得了显著的颜色类别知觉效应,且发声反应时不受字义与颜色名称一致性的影响.结果表明:在当前的实验任务中所获取的颜色类别知觉效应与语言标签无关,是一种纯知觉现象,从而为知觉特性理论提供了证据支持.

Abstract：

To examine whether the effect of color categorical perception is a perceptual phenomenon, the present research adopted a modified target-detection paradigm, in which a verbal interference task was combined with a target-detection task. The experiment data showed that a significant effect of color categorical perception was presented and that the response time for pronunciation was not affected by the semantic congruency between the word's identity and color property. These results suggested that effect of color categorical perception is independent of color naming. Thus, it is presumed that effect of color categorical perception is a pure perceptual phenomenon, which provides evidence to support the perceptual feature theory.
