| Outline of Final Research Achievements |
The present study investigated whether and how functional cerebral activity and connectivity in the early developmental stage relate to later language and social development. For this purpose, we performed a longitudinal study for typically developing infants, preterm infants and infants-at-risk at their age between 0 to 3 years-old to collect both behavioral and neurophysiological data. The results revealed that cerebral response to phonemic contrast can predict later language development particularly language production. Furthermore, our experiment using maternal vs. stranger’s speech indicated that exclusively for term infants, functional connectivities during listening to maternal speech were strengthened in the language brain areas and anterior superior temporal gyrus on the right side which is associated with social voice identification. These results suggest that cerebral activity in the early development can be a suitable predictor for later language and social development.
