| Outline of Final Research Achievements |
The situation model, which is constructed during a dialogue through the integration of spoken information, is essential in order to accurately understand a dialogue's contextual meaning. However, it has been difficult to investigate a situation model of dialogue. In this study, we created two types of scripted dialogues for participants: one develops a situation model (decisive script) and the other one does not (indecisive). The functional magnetic resonance imaging was conducted to assess relevant differences in brain activity between subjects who experienced a situation model and those who did not. The results showed that the left middle temporal gyrus was significantly more active during the decisive dialogue than during the indecisive dialogue. Thus, this area may be involved not only in comprehending simple sentential context in text, but also in processing of updating situation model of dialogue.
