本論文分析中文使用者如何選擇同意行為中相關之同意類別、同意程度、和語用策略。此外，本研究也檢視性別對人們同意使用的影響力。本論文採用言談分析(conversational analysis)作為研究框架。除此之外，本研究以言語行為理論(speech act theory)，合作原則(Cooperative Principles)及禮貌原則理論(Politeness Principles)作為理論基礎。 本篇論文調查八個雙人面對面的日常會話，其中同性別的會話共四份（包含男生和男生的會話兩份，以及女生和女生的會話兩份），跨性別之間的會話共四份。在這八段會話當中，總共找到152筆語料。在分析的過程中，先將同意的語料做分類，進而分析同意的類別、程度、語用策略的使用、社會因素(性別)，以及這四者之間的互動。 研究結果顯示，（一）同意類別方面，人們使用同意核心（Head act alone）和同意修飾語（Supportive moves alone）的頻率皆高於同意核心和修飾語的併用；（二）六個同意支類別方面，同意表徵（Agreement marker）使用頻率顯著高於其他五個同意支類別；（三）同意的強度方面，無條件同意（Agreement without contingency）的使用率顯著高於有條件同意（Agreement with contingency）；（四）無條件同意的支類別方面，強化同意（Upgrading agreement）的使用率顯著高於持平同意（Preserving agreement）；（五）語用策略方面，篇章修辭策略（Textual rhetoric strategies）的使用率顯著高於人際修辭策略（Interpersonal rhetoric strategies）；（六）篇章修辭策略的支類別方面，強調策略（Emphasis）和闡述策略（Elaboration）是最常被使用的；（七）修飾語的支類別和篇章修辭策略的互動方面，研究結果發現一項語用策略分工：強調策略通常使用於受同意的命題內容（Agreed propositional content），而闡述策略通常使用於新增的命題內容（Extra propositional content）；（八）人際修辭策略方面，研究結果也發現一項語用策略分工：讓步策略（Concession）通常使用於同意核心，而支持策略（Supporting）通常使用於同意修飾語；（九）最後，研究結果顯示性別會影響人們的同意使用情形。特別是女性容易在同意類別、同意強度和語用策略的使用上，受到聽話者的性別的影響。 / This thesis investigates people’s choice among categories of agreement construction, degrees of agreement, and pragmatic strategies in agreement. Also, the influence of gender is examined. Conversational analysis (CA) is taken as the framework of this thesis. Besides, speech act theory (Austin, 1962; Searle, 1975), Cooperative Principle (Grice, 1975), and Politeness Principles (Brown and Levinson, 1978, 1987; Leech, 1983) are theoretical foundations of this study. 8 face-to-face conversations, including 4 same-gender groups and 4 cross-gender groups, which yield 152 tokens of agreement, were investigated. Related data are classified and analyzed by categories of agreement, degrees of agreement, and pragmatic strategies in agreement, social factor—gender in this study, and the interaction among the four. The results of quantitative analyses confirm the following findings. (1) For categories of agreement, people apply both head act alone and supportive move alone more frequently than head act with supportive moves. (2) For the six subcategories of agreement, agreement marker overrides the other five. (3) For degrees of agreement, agreement without contingency emerges much more frequently than agreement with contingency. (4) For the subtypes of agreement without contingency, upgrading agreement is used significantly more than preserving agreement. (5) For pragmatic strategies, textual rhetoric strategies are applied much more frequently than interpersonal rhetoric strategies. (6) In textual rhetoric strategies, emphasis and elaboration are adopted most of the time. (7) For the interaction of subtypes of supportive moves and textual rhetoric strategies, a division of pragmatic labor emerges: emphasis often occurs in agreed propositional content, while elaboration often occurs in extra propositional content. (8) For interpersonal rhetoric strategies, a division of pragmatic labor is also located: concession often appears in head act alone, whereas supporting often appears in supportive moves alone. Lastly, (9) Gender is an influential factor in the use of agreement. Women are the one who tend to be influenced by hearer’s gender in their choice of categories of agreement, degree of agreement, and pragmatic strategies in agreement.
