論文摘要
我國學生雖然很少有機會直接觸到美國黑人，但是他們對黑人存有刻板印象，這種刻板印象可以用凱茲與布瑞萊式的問卷調查，以形容詞的方式顯現出來。另外包格達式問卷則可以測出我國學生對黑人的社會距離。
刻板印象的存在，雖然可能源於客觀的特徵，但是與我們簡化分類的認知方式，與內在挫折的投射也有關係，這兩個現象，均與專斷人格有密切的關聯性另一個傳散刻板印象的重要來源是大眾媒介。如電影、報紙或書籍，常使閱聽人形成偏見概念。而許多研究者，也使用電影或其他媒介，進行改變刻板印象的嚐試，而獲得成果。
最近一部以黑人立場描述黑入的影片「根」在台播出。由於影片含有極豐富的訊息，及對黑人的一個新觀點，因此可能有改變閱聽人認知結構的效果。本研究以影片之暴露強度，個人專斷人格量表分數及背景資料為自變項，以刻板印象對黑人及白人之社會距離及對「根」影集之重要觀點的態度為應變項，以瞭解這部影片的效果。
本研究的重要發現如下：
一、本研究樣本與白人和黑人的接觸機會均甚少，尤其對黑人，有接觸經驗者少於1/10，受訪者對白人與黑人的一致性印象，來自大眾傳播或親友的親身傳播。
二、受訪者的專斷人格分數隨著教育程度之上昇而下降。而男女的專斷人格分數之間並無差異。
三、看過根影集之大部份受訪者對白人的印象有點變壞，對黑人的印象有點變好，表示「根」影集有說服力。但說服效果隨教育程度之升高而遞減。
四、不同影集暴露強度之各組受訪者，對白人的印象並不因暴露強度之增高而有太大的變化，但是對黑人的印象卻隨暴露強度之增加而變好，縐勢明顯。
五、看過「根」影集四次以上的受訪者對黑人的刻板印象，遠比沒看過的受訪者為明確，也就是所選取的形容詞趨向一致。
六、在暴露於說服性傳播之後，專斷人格分數越高的人越容易被說服。本研究樣本中專斷人格高分組的受訪者中，看過根影集四次以上的人對黑人有很好的印象，對白人有很壞的印象。但是同組沒看過影集之受訪者，則對黑人有壞印象，對白人有好印象。自我報告態度改變分數與專斷人格分數，當暴露強度達到某一程度時，出現顯著之正相關，顯示出被說服性與專斷人格之間，有正相關存在。
