Understanding of Language in Early Development ( ) Research by Visiting Home (3) Center of developmenta1 education and research Center of developmenta1 education and research Center of developmenta1 education and research ABE, Satsuki TANAKA, Noriko FUJINAGA, Tamotsu This is the third report in s series of studies to clarify the process of early development of language acquisition in particular, how do the babies learn to understand language. We conducted research by visiting the homes of 4 normal subjects once a month for about 2 years. We asked the subjects mothers about the environment in which their babies grew up in, physical development and aspects of communication and language. We also observed the reactions to vocalizations and sounds, moreover we conducted tests using a series of picture cards. The results suggested the followings; the individual variations in responses to the stimulus and in expression of emotions are of sma11er significance in early babyhood and become more complex and varied as they get older, secondly the way and craving of communication and the 1

process of understanding everyday language is similar, finally as far as word production is concerned, individual variations seem to be greater at an early stage and lesser at an age of speaking a two-word sentences. We also found that there was thought to be some different spheres in understanding, secondly there were considerable differences in understanding representations, furthermore understanding in daily life did not necessarily reflect in understanding test representations using figure-card, finally parents' educational policy affected their own language development.
