本研究探討訓練情境中的情緒激發與知覺訓練難度對訓練成效之影響。本研究使用實驗法，採3（情緒激發：正向、負向、無激發）×2（知覺訓練難度：簡單與困難）完全受試者間設計，依變項為受訓者的自我效能、學習動機、訓練有用性與訓練學習結果。受試者為國立政治大學的127名大學生，受試者隨機分派到六種實驗情境之一，在實驗室中依序進行情緒激發作業、訓練作業，最後填寫研究問卷。本研究以變異數分析（ANOVA）與共變數分析（ANCOVA）（控制性別之影響）來檢驗情緒激發與知覺訓練難度對各依變項之影響。研究結果顯示情緒激發與知覺訓練難度之交互作用會影響受訓者的自我效能與學習動機。最後，本研究針對研究結果進行討論、並對研究限制、未來研究方向、理論與實務意涵加以闡述。 / This study focuses on the effect of emotional arousal and perceived training difficulty on training outcomes. A 3 (emotional arousal: positive, negative, control) x 2 (perceived training difficulty: easy, difficult) between-subject experimental design is used. The dependent variables are trainees’ self-efficacy, motivation to learn, utility judgment and learning outcome. Subjects (N=127) were randomly assigned to one of the six experimental situations and completed the emotional arousal task, training task, and research questionnaire in order. The researcher uses ANOVA and ANCOVA (controlling the gender effect) to examine the influence of emotional arousal and perceived training difficulty on each dependent variable separately. The results of the present study indicate that trainees’ self-efficacy and motivation to learn can be influenced by the interaction of emotion arousal and perceived training difficulty. At last, the results, limitation, further research directions and implications are discussed.
