本研究探討在兩人合作狀況下，當個人相對工作貢獻較合作夥伴多時，其在得知合作結果前後，是否會有不同的情緒強度與理由？研究者首先以60名受訪者為對象進行探索研究，以了解可能影響個體合作經驗的因素，並根據探索研究的結果設計正式研究問卷。正式研究中則以情境實驗法對150名大學生進行研究，分別在受試者得知合作結果之前（階段一）與之後（階段二），測量受試者的情緒強度與理由。階段一為完全受試者間實驗設計（2 × 2），探討作業重要性（高、低）與個人成就動機（高、低），對個人得知合作結果前情緒強度的影響。研究結果發現，個人得知合作結果前的情緒，並不因為成就動機高低或是作業重要性高低而有所差異。階段二為完全受試者間實驗設計（2 × 2 × 2），探討作業重要性（高、低）、個人成就動機（高、低）與合作結果（成功、失敗）三變項，對個人得知合作結果後情緒強度的影響。研究結果發現，個人得知合作結果之後的情緒，會受到作業重要性、合作結果及此二變項交互作用的影響而有不同。作業重要性高組的負向情緒強度比重要性低組強；合作結果失敗組的負向情緒強度比成功組強；當合作結果成功時，作業重要性高組與重要性低組的情緒差異不大，但是當合作結果失敗時，作業重要性高組的負向情緒比重要性低組的負向情緒更強。 此外，研究者也以描述性的方式，呈現全體受試者得知合作結果前的情緒理由、成功組與失敗組受試者得知合作結果後的情緒理由、受試者情緒變化的動態歷程以及在合作之後受試者可能的行為傾向。研究者最後檢討本研究的限制，以對未來的研究提出建議，並討論本研究在工商實務上可能的應用。 / The purpose of this research is to study individual's emotion intensity in a cooperative dyad when one's contribution to the task is more than his /her partner. Whether individual's emotion intensity differed after he/she knew the cooperative outcome was examined. Researcher first interviewed 60 subjects to gather the possible reasons that affect the cooperative experiences. The formal research design is base on the result of pre-experirnent interview. In the experiment, a story which described a cooperative condition of two people was used as the simulative task. 150 undergraduate students of National Chengchi University attended the experiment. Researcher measured their emotion intensity before (stage 1) and after (stage 2) they knew the result of the simulative task. A 2 (task importance : high or low) × 2 (achievement motivation: high or low ) between subject design was used to examine the effect on stage 1. The result showed that individual's emotion intensity did not affect by these two variables. A 2 (task importance : high or low) × 2 (achievement motivation: high or low ) × 2 (cooperative outcome: success or failure) between subject design was used to examine the effect on stage 2. The result showed that task importance, cooperative outcome, the interaction of task importance and cooperative outcome affected subjects' emotion intensity. Researcher also narrated the reasons of each kind of emotion, the possible dynamic process of individuals' emotion shift, and the possible behavioral intention of individuals. Researcher discussed the restrictions of the research, the suggestions for fUrther research, and possible applications of this research.
