The purpose of this study is to examine the memory mechanism of Chinese-to-Japanese consecutive interpretation in Chinese learners of Japanese based on the function of working memory (WM). In the experiment, through the presence or absence of articulation suppression task and the individual differentiators of WM capacity, it was investigated how the performance (information reproduction score and interpretation time) of consecutive interpretation was affected when phonological rehearsal was disturbed. As a result, it was found that (a) participants with large WM capacity had a high information reproduction score with articulation suppression, and (b) participants with small WM capacity were not affected by articulation suppression. Thus, it was clarified that when Chinese learners of Japanese performing Chinese-to-Japanese consecutive interpretation, information retention and processing at the comprehension stage diff er depending on the size of WM.
