| Outline of Final Research Achievements |
We conducted a set of longitudinal studies on children’s acquisition of rendaku. Rendaku is a morphophonemic process in Japanese that voices the initial obstruent of the second element (E2) of a compound (e.g., ori+kami→origami, k→g). Our participants were Japanese-speaking children with/without visual impairment (sighted, blind, low vision; monolinguals or several types of bilinguals). We conducted a series of experiments using compound noun formation tasks, PVT-R, and sentence production tasks. Our findings are of two folds: first, preschoolers do not follow the adult’s grammar of rendaku; they actively construct their original rule of rendaku by making reference to the pitch accent of E2. Second, after acquiring literacy, literate children developed adult-like rendaku strategies; however, the sighted children and the blind children developed different rendaku strategies in their middle childhood.
