本研究的目的，在以「哥倫比亞心理成熟量表」探討與三至八歲的語言障礙兒童普通推理能力有關的個人背景因素，施測所得資料利用多變項變異數分析、典型相關加以處理。本研究主要發現為： 1.不同性別與不同家庭社經地位的語障兒童，在普通推理能力結構變項上之得分無顯著差異。 2.不同年齡、有無兄弟姐妹與不同學前教育經驗的語障兒童，在普通推理能力變項上之得分具有顯著差異。年齡組較高的語障兒童在普通推理能力各變項得分顯著高於年齡組較低的語障兒童；無兄弟姐妹的語障兒童在「名稱」變項上的得分顯著較有兄弟姐妹的語障兒童為高；學前教育年數較長的兒童顯著在「形狀、顏色」、「數量」、「空間」、「名稱」、「機械或功能」、「其它」各變項得分較高。 3.語障兒童不同個人背景因素與普通推理能力間具有典型相關存在，透過第一個典型因素可知，個人背景變項中的語言理解與口語表達分數愈高時，則普通推理能力結構的分數亦愈高。

　　　　　The purpose of this study is to examine the speech disordered children from 3 to 8 years old in the general reasoning abilities which were measured by the "Columbia Mental Maturity Scale" (CMMS) and to explore their correlated factors. The data was analyzed by using the MANOVAs and canonical correlation analysis. The major findings of the study were as follows: 1. the scores of different sex and social economic status of the speech disordered children did not differ significanfiy in the general reasoning abilities. 2. The scores of different age, .the numbers of the siblings, and the preschooling experiences of speech disordered children differed significanfiy in the general reasoning abilities. The differences were evident in lower performance on 7 general reasoning ability variables for younger speech disordered children. The speech disordered children without siblings scored higher than those who had siblings in terms of Names. The differences were evident in higherperformance on Shapes g( Colors, Numbers, Space, Names, Machines & Function, and Others for the speech disordered children with longer preschooling experience. 3. There was canonical correlation between individual correlated factors and general reasoning abilities with speech disordered children. The first canonical factor indicated that the higher speech disordered children' Language Reception and Verbal Expression were, the better their general reasoning abilities increased.
