| Outline of Final Research Achievements |
This study investigated behavioral and neurological aspects of stuttering, and aimed to seek evidence-based treatments based on the understanding of mechanisms of stuttering. Eight-week practice using metronome sound had induced significant change of activity in the basal ganglia during speech production. The occurrence of stuttering under face-to-face condition was found to be related to the activity in the limbic system (amygdala). The speech performance under the delayed auditory feedback condition was related to the auditory evoked potential induced by the delayed auditory feedback sound. The auditory feedback perception was suggested to change by longitudinal mindfulness meditation practice. Rate of stuttering at 3 years of age was investigated in Japanese children. 1.4% of the children showed stuttering and 83% of them recovered.
