| Research Abstract |
The aim of this study was to investigate how Japanese infants acquire the two roles of prosodic information, 1) words distinction and 2) transmission of paralinguistic and non-linguistic information, in language processing. Using NIRS, I measured brain responses of 4- and 10 months infants to pitch pattern changes within words. The results demonstrated that 10-month-old infants show the different brain responses for the two roles of prosodic information.
