| Research Abstract |
The purpose of this study is to inquire into the cognitive mechanisms and their neurological basis fir the processing of compound words in spoken language comprehension. During the research period, we conducted the following five studies and presented the result at international conferences and published the papers in academic journals. (1) Behavioral studies on how phonological properties specific to compound words, the accent sill and the sequential voicing, affect the incremental compound processing. The results showed that native sinkers ran use these properties as effective cues for making forward prediction of up-coming elements. (2) Brain imaging studies on compound processing using Sal revealed that the left superior temporal gyms, as well as the bilateral superior temporal gyri and the bilateral insular, is recruited in the processing of auditorily presented compound words. (3) A series of studies on the effects of aspectual information in semantic processing was conducted. The results showed that mismatch between aspectual information increased cognitive bad of incremental sentence processing. (4) A behavioral study using self paced reading time measure and a neurological study using even-related potential measure were conducted on how and when processing load emerges in the processing of Japanese sentences with scrambled word order. Reading time increase was observed at the position of the nominative NP and the predicate. The brain potential component N400 was also observed at the position of the nominative NB (5) An eye-tracking study on sentence production was conducted using 'visual world paradigm'. The results suggested that lexical minding and structure assembly proceed in a parallel fashion in sentence production Sachiko Aoshima (Assistant Professor American University) and Jeff Lidz (Associae Professor University of Maryland, College Park) were invited to give seminars on recent development of sentence processing and language learning.
