The possible impact of decoding efficiency on incidental vocabulary has been currently suggested (Hamada, 2005; Koda, 2005). However, little data are available concerning how differences in decoding efficiency of Japanese EFL learners, if any, relate to the success of vocabulary learning and L2 word inference, and vocabulary learning processes. The present study aimed to clarify how Japanese EFL learners learn new words incidentally, especially in relation with lexical inference ability and decoding ability. Japanese college students, varying in L2 proficiency and decoding ability read English passages containing unknown words and attempted to guess the meaning of the target words from context. While reading a passage, they thought aloud their thoughts and inferencing strategies. The results showed that Japanese EFL learners' lexical inferencing is related with incidental vocabulary learning when their translation production task is used; Japanese EFL learners' lexical inferencing behaviors are partially similar to those ESL learners' in Nassaji (2003); Japanese learners' decoding ability is not strongly related with incidental vocabulary learning; naming task is more related with lexical inferencing than other tasks such as orthographic regularity task and pseudoword sounds task. The results of the study also suggest possible qualitative influence of decoding ability on lexical inferencing.
