ABSTRACT

[Purpose] The purpose of this study is to investigate verbal problem solving ability using indirect statements on adults with mild intellectual disability and to use the findings as basic data in the guidance. [Method] The subjects of this study were a total of 30 people of 15 adults aged 19-23 and 10-12 of language age with mild intellectual disability and 15 age-matched group of general children. This study intends to investigate verbal problem solving ability using indirect statements by developing a testing tool that includes indirect speech acts(sentence category, illocutionary act) and verbal problem solving ability(causal reason, inference of solution, supposition of clues). For data processing, this study conducted independent sample t-test, one-way analysis of variance, and Pearson's correlation analysis. [Results] When comparing the two groups, in all three cases (total score, interrogative sentence, declarative sentence), the score of the non-disabled student group was higher than that of the adults group with mild intellectual disability. Next, the group of adults with mild intellectual disabilities showed a higher rate of incorrect responses than the group of non-disabled students and the error type also showed significant differences between the two groups. Also, as a result of analyzing the four different situations, in particular, it was shown that there was a significant difference in the context of friends. Lastly, according to the result of investigating a correlation between vocabulary ability and language problem solving ability using indirect statement of adults with mild intellectual disabilities. It was identified that there is a distinct quantitative correlation between 3 different condition. [Conclusion] This study is considered to be have a significance in that this study has identified indirect statements and verbal problem solving ability of adults with mild intellectual disability using indirect statement sentences composed of dialogue, and hope to use these findings as a basis of verbal intervention.
