摘要
对国外学者对言语产生中的舌尖现象的研究进行了总结论述。舌尖现象产生的原因有:单层表征选择失败假说、词条选择假说和转换缺陷假说。舌尖现象的产生与年龄、双语音、词汇邻近效应、神经机制有关。
The researches of foreign scholars on the tip-of-the-tongue（TOT） in language production are summarized.The causes of TOT are：fail-single-selection hypothesis,selected-lemma hypothesis,and transmission deficits hypothesis.TOT is related to age,bilingual,lexical neighborhood eddects,and neural mechanisms.
