| Abstract(in English) | We observed the preschoolers' brain activities in listening to /ra/ and /la/ phonemic contrast by using near-infrared spectroscopy. Based on an auditory oddball paradigm, we used two types of auditory stimulus period where /ra/ phonemes were repeated, and where /ra/ and /la/ phonemes were randomly presented. In the participants of 3-4 years old, there was no difference in brain activities regardless of their English experiences. In the participants of 4-5 years old, on the other hand, the preschoolers with higher exposure to English showed more significant brain activities in their left hemisphere than those with lower exposure to English. These results suggest that English experiences affect the developmental changes of brain activities for phonemic processing of the second language. |
