本研究通过分析三个年级学生的词汇联想测试和控制性产出性词汇测试结果，探讨学习者心理词库组织模式和产出性词汇的发展特征以及二者的相关性。结果表明：(1) 学习者产出的横组合语义联结呈显著增长趋势；产出性词汇在二年级到三年级之间显著发展。 (2) 一年级组的产出性词汇和纵聚合语义联结之间有显著的正相关关系，二年级组的产出性词汇与百科知识联结之间存在正相关的趋势。(3) 总体上词汇联想测试各种语义反应构成的组合对于产出性词汇发展具有预测作用，其中横组合反应的预测作用最为显著。

By analyzing the results of a word association test and a controlled productive vocabulary test of EFL learners from three successive grades, the current research investigated the correlation between the organization of mental lexicon and the development of EFL Learners’ productive vocabulary. The results showed that: (1) The syntagmatic associations in different stages increased significantly and the productive vocabulary had shown a significant development trend between the second and third grade; (2) The productive vocabulary was positively related with paradigmatic association in the first grade and with world knowledge association in the second grade; (3) Generally speaking, the combination of different types of word association and, specifically, the syntagmatic associations had predictive effects on the development of productive vocabulary.
