舌尖现象和知晓感的关系研究

The Study on the Relation between Feeling of Knowing and Tip-of-the-tongue

舌尖现象(tip-of-the-tongue,TOT)和知晓感(feeling of knowing,FOK)都是日常生活中常见的现象,同时也是认知心理学领域的研究热点。以往关于二者关系的研究从其定义和判断的产生方式出发,认为舌尖现象只是强烈的知晓感体验,单单是强度上的一个延续。随着研究的深入,研究者从前额皮质机能在记忆提取中的作用着手,结果发现它们是性质不同的两种现象,主要体现在前额皮质机能对FOK判断的频率、准确性、强度等级等有显著影响,而对TOT报告的频率、准确性、强度等级等贡献不显著。

Tip-of-the-tongue and the feeling of knowing are not only very common phenomena but also a topic in cognitive area. In the past, their relations were discussed from their definitions and mechanisms, the study dedicated tip-of-the-tongue are merely strong feeling of knowing. With the development of the research, the researchers paid attention to the contributions of prefrontal cortex （PFC）in the retrival ,it shows they are qualitatively different phenomena. PFC functioning plays important role in reporting FOK, but no contribution of PFC was observed in reporting TOT.
