Abstract

The present study was intended to investigate the possibility of applying a graphic symbol system (NSL86) to language intervention with language-deficient children. The subject was a 9-year-old nonspeaking child with mental retardation. After the assessment of linguistic abilities, the following training began in the following order; word training, two-word combination training, and three-word combination training. The subject was trained in comprehension and production of symbols simultaneously. Symbols learned in the word training were moved on a pointing communication board for use in daily communication.<br>After approximately 15 months of instruction, the subject learned to comprehend and produce 96 symbols (68 nouns, 22 verbs, and 6 adjectives) and their combinations in sentences such as agent+action, object+action, and agent+object+action. The results showed that the overall accuracy of symbol production was higher than that of symbol comprehension. Intentional use of a pointing communication board was also observed both in the training setting and in the home situation. Consequently, this research suggests the possibilities of NSL86 as a means of nonspeech language intervention.
