Abstract:	團隊使用溝通媒介進行互動以利於資訊交換並提升任務績效。在以往的社會裡，人們多仰賴面對面溝通；隨著資訊與通訊科技之新興與進步，促進了電腦輔助溝通型態的發展，逐步顛覆傳統的溝通模式。然而，過去有關電腦輔助溝通之相關研究主要偏重於媒介的選擇與適配上。本研究著重於媒介的實際使用與績效上，探討於文本電腦輔助溝通環境下，當團隊併用多項電子媒介時，是否真能促進其資訊分享溝通績效，進而達成其團隊任務績效。本研究以下列四項團隊互動元素：「資訊分享廣度」、「資訊分享深度」、「共同理解」、「認知負荷」以揭示文本電腦輔助溝通對於團隊任務績效表現上之間接影響。本研究以大學生為樣本執行實地實驗法，並輔以問卷及成果評量以收集資料。研究結果發現：(1) 文本電腦輔助溝通對資訊分享廣度有正向影響。(2) 文本電腦輔助溝通對資訊分享的深度有負向影響。(3)資訊分享廣度對任務績效有正向影響。(4)共同理解對任務績效有正向影響。(5) 文本電腦輔助溝通會增加認知負荷。（6）認知負荷對共同理解有影響。(7) 資訊分享深度對任務績效的影響、認知負荷對任務績效的影響與文本電腦輔助溝通對共同理解的影響皆未達顯著標準。 Team task performance depends on the level of interaction necessary to support information sharing facilitated by communication media. In the past, team members mainly communicate face to face. With advances of information and communication technologies, computer-mediated communication thrives leading a round change of daily communication pattern. Past studies on computer-mediated communication emphasize media choices and fits with tasks. This study explores the relationship of media use and task performance. To open the black box surrounding the effects of text-based computer-mediated communication on task performance, the current work employs four group interactive mediating variables: breadth of information shared, depth of information shared, shared understanding, and cognitive load. A field experiment is designed to examine the research model and posited effects with undergraduate students as subjects. The findings from our samples indicate that text-based computer-mediated communication has positive influences on breadth of information shared and cognitive load, yet negatively affects depth of information shared. It’s also found that both breadth of information shared and shared understanding have positive effects on task performance. Besides, no significant relationships are found between depth of information shared and task performance, cognitive load and task performance, and text-based computer-mediated communication and shared understanding. Keywords: text-based computer-mediated communication, intersubjective interpretation, shared understanding, cognitive load, team task performance
