本研究旨在探討不同年級、性別及接觸程度之國小四、五、六年級學生，對智障同儕所持態度之內╱外在成份間所存在的不一致性。研究者在臺南縣╱市及高雄縣╱市中抽出719位有效樣本，以自編之「國小學生對智障小朋友的態度量表」施測，測得資料以三因子變異數分析褣行統計分析，其結果如下： 一、在性別方面 1.國小女生態度內╱外在成份間所呈現之不一致性，乃較國小男生為大。 二、在接觸程度方面 1.不同接觸程度之國小男生之間的態度內外轉化差，未達顯著差異。 2.在國小六年級女生中，高接觸程度者之態度內外轉化差乃分別較低╱零接觸程度者為大，但低╱零接觸程度者之態度內外轉化差間並無明顯差異。 3.在國小四年女生中，低接觸程度者之態度內外轉化差乃較零接觸程度者為大，但高╱低接觸程度者之間、以及高╱零接觸程度者之間，其態度內外轉化差則無明顯差異。 三、在年級方面 1.在高接觸程度者之中，六年級女生態度內外轉化差較五年級女生為大。 2.在低接觸程度者之中，四、五年級女生態度內外轉化差皆分別較六年級女生為大。 3.在零接觸程度者之中，不同年級受試者的態度內外轉化差之間則無顯著差異。

　　　　　This study aimed to investigate the effects of the three independent variables (i.e,. grade, sex, and contact) on the differences between both psychological and behavioral components (DPBCs) within the attitudes of the primary school students toward their mentally retarded peers (MRPs). The researcher sample 719 primary school students from both Kaoshiung County/City and Tainan County/City (in Taiwan), and also tested them with "Scale for the Attitudes of the Primary School Students toward their Mentally Retarded Peers", designed by the researcher. The data were analyzed with 3-way ANOVA. The results indicated as follows: 1.The DPBCS within the attitudes of the female students toward their MRPs were larger than that of the males. 2.The effect of "contact" on the DPBCs within the subjects attitudes revealed as follows: (1)The DPBCs among the male students with different contact frequencies revealed no significant differences. (2)Of all 6th female graders, the DPBCs of those who had ihgher contact frequency were larger than that of both those who had lower and who had no contact frequencies, but the DPBCs between those who had lower and who had no contact frequencies revealed no significant differences. (3)Of all 4th female graders, the DPBCs of those who had lower contact frequency were larger than that of those who had no contact experiences, but the DPBCs between those who had higher and who had lower contact frequencies, and between those who had higher and who had no contact frequencies were both revealed no significant differences. 3.The effect of "grade" on the DPBCs within the subjects' attitudes revealed as follows: (1)Of all those who had higher contact frequency, 6th female graders' DPBCs were larger than the of 5th female ones'. (2)Of all those who had lower contact frequency, 4th and 5th female graders' DPBCs were respectively larger than that of 6th female ones'. (3)Of all those who had no contact experiences, the DPBCs among different graders revealed no significant differences.
