本研究視理性思考與感性人格特質為多面向的結構，探討理性思考與感性人格特質各面向間的關係，並研究個人的性別、學科背景是否與其理性思考及感性人格特質有關。 　　本研究以台大、政大共386位學生為樣本，運用「修訂康乃爾批判思考測驗Z級」、「拓弄思語文創造思考測驗乙式」、「人際敏感性量表」、「美感追求量表」、「感情變異性量表」、「自發性量表」及「同理心量表」等工具收集資料，再以皮爾遜積差相關考驗及多變量變異數分析(MANOVA)進行統計分析。 　　研究結果發現： 　　1.理性思考與正面向感性人格特質有顯著正相關，與負面向感性人格特質沒有顯著相關。 　　2.在理性思考上，性別之間並無顯著差異；在感性人格特質上，女性在「美感傾向」、「同理心」、「情緒化」等三個面向上的分數都顯著高於男性，「情感表達」面向則是未達顯著水準，但是在「人際敏感」面向上卻是男性分數顯著高於女性。 　　3.不同學院學生的批判思考、創造思考及理性思考能力並未有顯著差異。文學院學生的感性人格特質則有「情緒化」面向顯著高於理學院學生及其他學院學生，「人際敏感」面向高於其他學院學生。 　　本研究建議，根據理性思考與感性人格特質之間的相輔相成互動關係，學校宜多鼓勵男學生培養感性人格特質，鼓勵女學生發揮理性思考的潛能，不受刻板印象所限；在大學的通識教育上亦有必要重新調整，提供學生培養經驗整合與整全判斷能力。 / The objectives of this study were to explore the relationship of rational thinking, consisted of critical thinking dimension and creative thinking dimension, and affective personality traits, consisted of four positive dimensions and one negative dimension, from a multidimensional perspective, and to examine if one's sex and major would have influence on his/her rational thinking and affective personality traits. Tests were administered to 386 college students, evaluating their levels of critical thinking, creative thinking, interpersonal sensitivity, aesthetic orientation, emotioanl expressivity, empathy and emotionality. Findings suggest that: (1) Subjects scoring high on Rational thinking have significant high scores in positive dimensions of affective personality traits, but it seems that rational thinking is not related to the negative dimension of affective personality traits. (2) There is no significant sex difference in rational thinking, meanwhile in affective personality traits, female score obviously higher in aesthetic orientation, empathy, and emotionality, and there is no significant sex difference in emotional expressivity, but male score higher in interpersonal sensitivity. (3) Students in different majors don't have significant differences in their critical thinking, creative thinking, and rational thinking abilities, but students majoring art and literature surely score higher in emotionality and aesthetic orientation dimensions than students majoring nature science or other subjects.
