聽覺中樞功能篩檢測驗賡續研究

A Screening Test for Central Auditory Function

本型態與年級在測驗分數上所呈現之趨向、各測驗之相關、分測驗難度之排序以及普通班與啟智班得低分之兒童各佔了多少比例。研究結果顯示測驗分數會因兒童就讀之班級型態與年級而有顯著差異（p＜0.001）；就年級而言，資源班與啟智班各分測驗得分與總分隨就讀年級之增長而呈現成長之趨向，普通班兒童則呈現直線、二次與三次之成長趨向，年級越高，得分越高；就班級型態而言，各分測驗得分與總分都隨兒童就讀之班級型態（普通、資源、啟智）呈現直線降低之趨向，同一年級中，各分測驗得分與總分由高至低之順序為普通班兒童、資源班兒童、啟智班兒童。就性別而言，各分測驗得分與總分不因普通班與資源班兒童性別而有顯著差異，唯獨啟智班兒童在音調辨識測驗之得分與總分方面因性別而有顯著差異（p＜0.05），且男童得分高於女童。三個分測驗之難度因兒童就讀之班級型態而異，普通班與資源班兒童在溶合測驗之表現都最差，他們在其餘兩個分測驗的表現相近。啟智班兒童則是在音調辨識與溶合測驗表現較差，低通測驗則表現最佳。各測驗得分及總分彼此間之相關都達到0.001顯著水準。一、二、三年級普通班兒童在各分測驗表現低於啟智班兒童各分測驗平均數者分別有7.3％、9.8％與9.2％，資源班則是20％、23.3％與16.9％。這些兒童有待進一步做更詳細之聽覺中樞功能檢查。

A Central Auditory Function Screening Test (CAFST) which included three subtests, lowpass, fusion and pitch perception tests, was made. The purposes of the study were to investigate (1) the effects of educational placement (normal class, resourceroom, MR class), grade (kindergarten, grade 1, 2, and 3) and gender on scores of CAFST, (2) how well the CAFST discriminate among three levels of educational placement and three different grades, (3) correlation among subtests, (4) the order of difficulty of subtests, and (5) percentages of subjects who scored lower than MR subjects. Totally 1898 subjects were tested. Results showed the following. Both educational placement and grades had significant effects on scores. Linear trend was observed in scores of resourceroom subjects and MR subjects at different grades, and the higher the grade, the greater the scores. Scores of normal-class-subjects showed linear and nonlinear trends. Linear trend was also observed in different levels of educational placement, and subjects of normal classes scored the highest, while MR subjects scored the lowest. MR boys scored significantly higher than MR girls in pitch perception test. The order of difficulty of subtests varied with educational placement. The correlation among subtests were all significant (p＜0.001). There were 7.3%, 9.8% and 9.5% of normal-class-subjects and 20%, 23.3% and 16.9% of resourceroom subjects who scored lower than average scores of MR subjects in three subtests of CAFST.
