本篇論文的目的在於探討兒童在親子對話中行使重新請求 (request reformulation) 的情況，研究問題如下: 1.兒童採取哪些重新請求的策略以達到請求的目的? 2.親子對話中，常見的重新請求的序列模式（patterns of request reformulation sequences）為何？ 2.如何從兒童重新請求的使用反映出角色取代能力 (perspective-taking ability )的發展? 研究對象為一位三歲和一位六歲的男孩。研究結果顯示隨著年紀的增長，兒童能使用更多元的重新請求策略。研究也發現造成請求失敗的原因隨著不同年齡的兒童有所差異。隨著年紀的增長，兒童面臨的失敗原因和挑戰日漸複雜、困難，兒童會依據不同的失敗原因採取重新請求的策略。最後，研究顯示不同年齡兒童採取的重新請求策略可以展現出他們不同階段的角色取代能力的發展。三歲的兒童無法跳脫自己的觀點而從別人的角度來看待自己的請求，所以重新請求著重於強調自己的需求。六歲的兒童較能夠從別人的立場看待自己的請求，所以他較有能力在考量對方的觀點和利益之後採用對雙方有益的策略。 / The purpose of this study is to explore how children at different age make reformulation to compensate for an unsuccessful request. Firstly, we aim to investigate what reformulation strategies children apply and the patterns of reformulation sequences. Second, we further aim to explore how children’s use of reformulation strategies reveals the development of perspective-taking ability. The data analyzed are natural conversations of two Mandarin-speaking mother-child dyads. Subjects in this present study are two male children. One subject is three years and six months old and the other is six years old. The strategies of request reformulation adopted in this study are mainly based on Levin and Rubin’s (1984) categorization. The results show that children would have a greater variety of reformulation strategies as they get older. Furthermore, aggravation and explanation are both children’s main strategies of reformulation. With the growth of age, children decrease the use of aggravation and increase the use of bargain and mitigation. Furthermore, the results of reformulation sequences reveal that the two children are confronted with different causes of the failure to obtain compliance, which influences their adoption of reformulation strategies. The younger child faced the communicative breakdown and his mother’s ignorance while the older child encountered his mother’s queries and disagreements. Finally, the two children’s application of reformulation strategies revealed their different ability to take the other’s perspectives. The younger child’s reliance on aggravation and speaker-oriented negotiation reveals that he is embedded in his own viewpoints and is less able to view his request from the hearer’s viewpoints while the older child is more able to view the request from the hearer’ perspective and take her benefits into account. Our findings throw some light on children’s use of request reformulation strategy and the development of the perspective-taking ability.

本篇論文針對三位以臺灣華語為母語的音韻異常兒童，採長期觀察的方式，研究中文顎音[tɕ, tɕʰ, ɕ]的習得狀況與產製現象。習得狀況方面，詳細描述顎音的習得順序、常見的語音錯誤之音韻歷程、延遲的音韻歷程類型、錯誤取代模式隨著年紀增長而改變的情形。產製現象方面，本篇論文探討了顎音所在音節的音節複雜度(Syllable complexity)是否會對顎音的正確率以及錯誤取代狀況有所影響。 本研究共觀察三位年齡為三歲十個月至五歲三個月且正在接受語言治療的音韻異常兒童長達六個月，以每週一次的頻率前往醫院收集幼童與語言治療師之間的自然對話，並利用錄製回來的影音檔做譯寫和分析。 結果顯示，音韻異常兒童的顎音習得狀況有以下現象：(1)顎音發展較為停滯，幾乎沒有隨著年齡的增長而有進步的現象。(2)音韻異常兒童在發顎音時，會系統性的使用不該是他的年齡所應該出現的音韻歷程。(3)顎音的語音錯誤之音韻歷程種類不多，但使用的頻率卻非常頻繁。上述結果皆驗證了前人文獻的研究結果(Stoel-Gammon & Dunn, 1985; Jeng, 2011)。除此之外，本研究也發現音韻異常兒童具有以下特徵：(4)音韻異常兒童能夠察覺兩個音之間送氣特徵(aspiration feature)的不同，在選擇替代音時，也會選擇與目標音有相同送氣特徵的音來取代。(5)音韻異常兒童的語言能力和語言表現之間有落差，也就是說，他們知道能夠區辨出哪個是正確的音，但卻無法正確的使用該語音。(6)音節複雜度會對音韻異常兒童的顎音產製造成影響。因此，音韻異常兒童在顎音的習得狀況和產製表現上都和正常兒童不同。 音韻異常兒童使用的錯誤音的模式顯示塞擦音基底形式中的[stop]成分及[cont]成分並非均等(asymmetrical relationship)，且塞擦音是屬於以左邊的成分為主要核心的語音(left-headed)，並從第一語言習得的觀點為塞擦音的真實面貌提供了一項證據。 / The purpose of this study is to discuss the issue concerning the acquisition and production of Mandarin palatals [tɕ, tɕʰ, ɕ] in Taiwan Mandarin-speaking disordered children. Four aspects regarding the acquisition of Mandarin palatals are included in this study: the order of acquisition, the phonological processes involved, the delayed phonological processes, and the path of error patterns. In addition, the effect of syllable complexity on disordered children’s palatal production is also examined. Three disordered children (aged 3;10 to 5;3) who were identified as having delayed phonological development are investigated in this study. A six-to-seven month of longitudinal observation is conducted by recording the spontaneous speech between the therapists and the children during the process of speech therapy. The results showed that phonologically disordered children have the following characteristics on palatal acquisition and production: (1) static phonemic system that stops at an early level of development, (2) persistent uses of delayed processes, and (3) frequent uses of phonological processes. These characteristics were asserted in the literature (Stoel-Gammon & Dunn, 1985; Jeng, 2011) and have been proved in this study. In addition, we found that disordered children are unconsciously able to notice the aspiration feature of two sounds, and will use an error sound that has an identical aspiration feature with the target. Moreover, the disparity between the linguistic competence and the linguistic performance in the disordered children was also found. Last, syllable complexity has found to affect disordered children’s palatal production. The substitution errors used by the disordered children support Schafer’s (1995) study, in which he claimed that the underlying representation of affricates is left-headed. To sum up, this study has provided a piece of evidence for the unsolved issue of the nature of affricates from the field of first language acquisition, and might serve as a reference for parents and speech therapists for understanding palatal acquisition and production in disordered children.

本研究探討兒童在給予非優先應答時所採取的語用策略，以及母親在接續的對話中所給予的回應。研究的語料來自於一名以漢語為母語的四歲兒童與她的母親之間的日常對話。在分析的資料中，我們將非優先應答區分成拒絕和異議兩類，分析之後，結果發現受試兒童採取六種不同的語用策略來表達非優先應答，分別為(1)直接否定(simple negation)、(2)理由(account)、(3)挑戰(challenge)、(4)修正(correction)、(5)部分認同(partial agreement)、(6)反請求(counter-request)，而受試者的非優先應答往往結構簡單，內容直接而缺少修飾，雖然她在否定或提出異議時，能給予進一步的解釋，但是她所提出的多為以自我為中心的理由。另外，母親在面對受試者直接的拒絕或異議時，多半會以下列三種方式回應：一、再次陳述自己的要求或想法，二、提供更多的解釋來說服對方，三、提出問題要求對方進一步說明拒絕或不同意的原因，以上的三種回應策略都使母親有再一次的機會來說服受試兒童接受她的要求，或者同意她的想法。 / This study investigates children’s pragmatic strategies of delivering dispreferred responses and also how the mothers reacted in the subsequent turns. The data analyzed are a Mandarin-speaking four-year-old child’s natural conversation with her mother. In the observed verbal exchanges, the subject child’s dispreferred seconds are categorized into refusals and disagreements. After careful examination, six pragmatic strategies are identified in the dispreferred turns, namely, simple negation, account, challenge, correction, partial agreement, and counter-request. The results indicate the child’s dispreferreds are generally simple in structure, direct and unmitigated in force. Though she was capable of providing accounts for her refusals or disagreements, the reasons she gave are mostly self-oriented and serve to express her non-compliance and disapproval. As for the mother’s subsequent responses, it is found that facing the child’s direct and socially disruptive seconds, the mother generally targeted at her previous turn and attempted to carry on the prior illocutionary force. When her directive or statement was refused or denied, she tended to responded with reformulations, persuading remarks or queries, which elicited more information about the dispreferred acts. All of these three strategies provided another chance for the achievement of compliance or agreement.

本研究的目的為探究中文母子對話中，母親的互動風格與話題延續的關係。 研究問題為: (a)本研究中兩位母親的互動風格為何? (b)兩位孩童的話題延續表現有何不同? (c)母親的互動風格與話題延續有怎樣的互動關係? 研究語料為兩組親子互動的自然語料，各取三個小時，孩童的年紀約為三歲。研究結果顯示兩位母親的互動風格有所不同，分別屬於命令型和引誘型。 而小孩的在話題延續上表現則是相近，大多用回應母親問題的方式來延續話題並且能在不同的情境中提供新資訊。對兩組親子互動的探究顯示命令型的母親比較不會延續對話而經常改變話題，造成較短的話題片斷。引誘型的母親則較注重對話的延續且較少改變話題，造成較長的話題片斷。 / The purpose of the study is to investigate the interaction of the maternal interactional styles and topic maintenance in Mandarin mother-child conversational interaction. There are three research questions: (a) What are the mothers’ interactional styles in the current case? (b) What are the differences among children’s competences of topic maintenance? (c) How do the maternal interaction styles interact with topic maintenance in the conversational interactions? Naturally occurring conversations of two dyads' conversational interactions were adopted as the data and analyzed. Results suggested that while the two mothers differed in terms of their interactional styles, the two children showed nearly equal sophistication in terms of their topic-maintaining competences. Examinations of the two dyads' interactions also revealed that the directive mother was less interested in maintaining the conversations, changed topics more frequently, and maintained discourse topics for less turns. The conversation-eliciting mother paid more attention on maintaining of the conversations, change topics less frequently, and maintained discourse topics for much more turns.
