Washburn), which revisits the issue of negative evidence in second language classrooms.

The third paper, "What Is Missing in Interlanguage? Acquisition of Determiners by Korean Learners of English" (Hyun-Sook Kang), studies the acquisition of a new functional category in the interlanguage development of advanced Korean students. The fourth paper, "A Study on Closing Sections of Japanese Telephone Conversations" (Tomoko Takami), examines how closings are realized in Japanese telephone conversations between intimates.
