| 概要 | This study examined the development of lexical knowledge in compositions written by Chinese learners of Japanese, with reference to Dynamic Systems Theory (DST). Lexical knowledge was analyzed thro...ugh 15 indices covering three dimensions: lexical breadth, lexical depth, and lexical access-related aspects. The study aimed to identify indices sensitive to developmental changes, examine their longi- tudinal patterns, and clarify the changing relationships among the three dimensions. The results showed that Guiraud’s index and the former JLPT Level 1 vocabulary ratio reflected lexical breadth, the average polysemy of nouns and overall vocabulary reflected lexical depth, and the production–reception familiarity gap and average abstractness reflected lexical access-related develop- ment. Lexical development was found to be nonlinear, involving fluctuations, stagnation, and change points. The early stage was characterized by basic lexical expansion, the middle stage by increased varia- bility and reorganization, and the later stage by growth in diversity and abstractness. The relationships among the three dimensions also shifted across learning stages, showing both complementary and com- petitive patterns. These findings suggest that lexical development should be understood as a dynamic process involving the interaction of multiple lexical subsystems.続きを見る |
