本研究探討溝通動態與手勢之關係。本研究相較於過去的研究提供了中文口語語料的量化結果，除了檢視語言上的溝通動態值與手勢出現、手勢類型的關係以外，並加入手勢特徵進而檢視。語言上的溝通動態值分別以「資訊狀態」與「主題連續性」來決定溝通動態值之高低，並且將手勢所伴隨的語詞依詞性分開分為名詞與動詞，檢視是否手勢上會依循語碼原則（the coding principle）：當溝通動態值越高，所使用的代碼材料便越多；當溝通動態值越低，所使用的代碼材料越少。結果發現，以決定溝通動態值的標準來看，資訊狀態較主題連續性更能依語碼原則反應溝通動態值。原因是因為資訊狀態反應訊息的新舊差異性，而主題連續性反應的是舊訊息當中的不同的「舊」的程度差異，因此前者較能反應溝通動態與手勢之關係；而以手勢伴隨的語詞而言，動詞較名詞更能依語碼原則反應溝通動態值。因為動詞相較於名詞而言，在語言上無完整的語碼系統以反應溝通動態值之高低，因此倚賴手勢出現與手勢特徵來反應語言上的溝通動態值之高低。 / The study investigates the correlation between communicative dynamism (CD) and gesture. Different from the previous studies, the present study provides quantitative analysis based on Chinese conversational data. The study examines the correlation between CD in language and the occurence of gestures, gestural types and gestural features. The various degrees of CD are deteremined by two separate criteria, namely “information status” and “topic continuity”. Morover, the study also distinguishes between the nominal affiliates of gesture and the verbal counterparts. The study found that gestures occur at the two extremities of CD. Gestures tend to co-occur with linguistic elements bearing the highest or the lowest CD. In addition, based on the criterion of “information status”, stroke duration and handedness were found to reflect the various degrees of CD. On the other hand, based on the criterion of “topic continuity”, all gestural features including stroke duration, gestural space, handedness and stroke frequency have no correlation with CD.
