重度脳性麻痺児における言語行動形成の試み

抄録

2 severely handicapped cerebral palsied Ss (Y. K. & T. N.) who could hardly control their limbs voluntarily nor articulate speech sounds were given a systematic training for the formation of verbal behavior. Y. K., in addition to severe paralysis in his speech apparatus, had a hearing loss in high frequency bands; therefore, letters were selected as the medium for both receptive and expressive system. In T. N., vocal sounds as the receptive medium, and configulational patterns consisting of seven dots as the expressive medium were used respectively. To use these signs as media, essential learning process necessary for the differentiation of receptive system and for the formation of expressive system by voluntary movement was explored, and then, several steps were taken to facilitate the correspondence of the sign system to phenomenal objects or behavior system.
