类母语水平是二语习得水平的上限。本文以英语本族语者词汇联想结果为参照计算联想比，考查具体性对于二语学习者词汇发展类母语水平是否有显著影响。研究问题包括：1）具体性对于二语词汇反应词的联想比有何影响？2）具体性对于二语独有概念反应词的产出有何影响？结果显示，具体词和抽象词在两个方面都表现出了显著的差异性，表明具体词发展的类母语水平更高，更加接近母语者。研究结果验证了双重编码理论和语境有效性理论。

Nativelikeness is the end state of the second language acquisition. Few researches have tackled the issue of concreteness in L2 processing from the perspective of nativelikeness. A word association test was conducted in this study to explore whether the concreteness has significant effects on the association proportion and the inactivated responses of L2 learners. The results showed that the association proportion of concrete words is significantly higher than that of the abstract words; and, referred to the results of native speakers, the concrete words had few inactivated responses than those of the abstract words. The results suggested that the development of concrete words was faster than that of the abstract words in the process of nativelikeness, which provided new evidences for the dual-coding theory and the context availability model.
