157.More accurate measurement of second language processing

Outline Periods
The objective of this team is to develop more accurate measurements of linguistic information in a second language through experimental research. Since linguistic information is processed in the brain and difficult to observe directly, tasks (e.g., question/problem) must be given to learners to infer as explicitly as possible the mechanisms of linguistic information processing they engage in. However, subsequent processing is expected to differ depending on what kind of task is used. In this research we focus on task differences in order to clarify relationships with language processing. Based on the findings from our experimental studies, we will assess task differences to contribute to more accurate measurement of linguistic information. The outcomes of this research are expected to guide the development of more effective instruction, teaching materials, and testing.
