網路影響人類生活的各方面，特別是網路溝通的影響。本研究探討於網路溝通的情境下，運用網路文字及網路表情圖進行表達，對於表達者情緒的強度有何影響。這些新發現提供未來以網路作為媒材研究情緒的重要參考。本研究運用量化的準實驗法（2×2，正向與負向情緒×網路表情圖與網路文字，共四組相互比較）探討了使用者運用網路文字或表情圖表達後情緒強度的差異。並且探討不同性別的情緒強度差異，以及網路表達方式的傾向。研究結果顯示，正性情緒誘發下，表情圖組的正性情緒強度顯著高於文字組。負性情緒強度在不同表達方法下，則無顯著差異。而不同性別者在網路表達後的正性以及負性情緒差異皆不顯著。在負性情緒條件下，使用網路文字和表情圖的偏好差異顯著，更偏向使用網路文字的表達。因此，運用不同網路表達方式在網路溝通中可能對情緒造成不同的影響。

In the digital era, online activities, especially online communications, have remarkably changed people’s lives. Considering this, the researcher focused on the internet words and emoji expression’s influences on emotional intensity. This study utilized quasi-experimental methods to examine 80 subjects who had the experience of online chatting, by 2×2 two factors and four groups between-subjects design. One factor was the types of induced emotion as positive and negative emotions. The other factor was the types of expression as internet emoji and internet words expression. Four groups of samples’ emotion were induced. Then, participants expressed their emotion and completed the questionnaire with questions of emotional intensity, physical sex, and expression preference. The results of the study indicated that under the positive emotion condition, the emoji expression group had a significantly higher emotional intensity than that of the internet words expression group. However, under the negative emotion condition, emotional intensities between internet words and emoji were not significantly different. Second, under both the negative and positive emotion, the emotional intensities between males and females were not significantly different. Lastly, participants reported a preference for using words expression when they were in negative emotion. In conclusion, the utilization of internet words and emoji highly probably influenced some parts of human emotion. Particularly, using emoji might enhance positive emotion. However, the dynamic emotional processes can be further explored.
