This study was designed to find out the developmental process of linguistic framework for information processing in deaf and normal children. Subjects were children aged 7 to 17 years. Their responses in word-association showed two kinds of structures of the framework. One of them was composed of idiomatic phrases or sentences while the other was composed of words only. With normal children, it was observed that the former developed into the latter: however, with deaf children, the development was reversely evolved. There were two types of children's responses: contradictory and contrary types. These different types suggested different ways in processing. In the former, informations seemed to be divided into two groups,“A” and “non-A”, and in the latter,“A” and “anti-A”. While the former type developed into the latter, another period was observed between these two periods, in which perceptual imagery was explained in words. With deaf children, the information processing of the contrary type suffered a delay of 5 to 6 years. Such delay seemed to proceed from the delay observed in the preceding two periods.
