This study aims to investigate the skills of normal children and the children with intellectual disabilities to express verbs and nouns and compare the differences in skills between two groups- normal children and the children with intellectual disabilities. To this end, comparing the differences in skills to express verbs and nouns between two groups, and comparing the differences in the skills to express verbs and nouns between two groups by age - 3, 4, and 5 year old- , were established as research problems for this study. In addition, this study also aims to compare the differences in the development of the skill to express verbs and nouns by age between two groups. As for the subject of this study, 3, 4 and 5 year old normal children and the children with intellectual disabilities, 10 children each by age, were selected, and a test for expressive vocabulary skills for each child was performed to calculate the mean and the standard deviation. To compare the skills to express verbs and nouns between to groups, statistics was processed and verified, using t-test. The findings from this study are as follows.
First, as for the skills to express verbs and nouns, normal student had higher skills and both groups used more nouns than verbs.
Second, as for the skills to express verbs and nouns between two groups, normal children and the children with intellectual disabilities, by age - 3, 4, and 5 year old-, 3, and 5 year old normal children had better skills for both verbs and nouns, and the children from both groups used more nouns than verbs. On the other hand, 4 year old normal children and the children with intellectual disabilities used nouns at a similar level; normal children used more verbs; and both group students preferred nouns to verbs. Thus, both groups had better expressive skills for nouns with specific references than the verbs indicating action.
Third, when comparing the development of the skills to express verbs and nouns between two groups, normal children and the children with intellectual disabilities, the older they were the higher the percentage of correct answers, which indicated the use of vocabularies increased after 3.
Thus, as for the language intervention for the children with intellectual disabilities, suggesting verbs indicating action and state as well as nouns used to name objects or to speak specific concept is needed to accelerate the development of vocabularies for children. In addition, as the vocabulary development of the children with intellectual disabilities children is delayed compare to normal children, teaching in compliance with the developmental stage the normal child's vocabulary development will help the vocabulary development of normal children.
