| Outline of Final Research Achievements |
The present research investigated how young children (2 years old)’s perception and production interact with each other to feed subsequent morphological and syntactic processing through longitudinal experimental studies. Using child-friendly visual(and tactile) stimuli we developed three different experimental paradigms for both the sighted and the blind. We have obtained three major findings. First, sighted and blind children showed different language processing strategies in their middle childhood and beyond. Second, children develop their syntactic processing skills in a stepwise way. They acquire transitive constructions as early as 3 years old but their causatives and passives come around 4 or later. Finally, sighted children(2yrs.) start with the universal left-headed compound processing; then they changed it to the language-specific right-headed processing at the age of 3.
