| Outline of Final Research Achievements |
Neuroimaging studies have observed that scrambling construction requires more cost for processing in many languages. Why we produce such a costly sentences? Analysis of Japanese corpus found that scrambled sentences often have 'heavy' object noun phrase (NP) modified with a clause. We examined brain activation during the processing of sentences with heavy object NP.Results showed that the heavy object NP scrambling did not cause brain activation increase compared to its canonical counterpart. We conclude that the motivation to produce scrambled word orders is that placing the longer NP at the sentence initial position can mitigate the cost of processing than having it in the middle position as in the serial order effect in working memory.
