    Abstract: 過去拼音文字語言的口語字彙辨識的研究證據顯示：起始音段相同字彙有較早且強的競爭效果；而末段音段相同字彙有較晚且弱的競爭效果。本計劃利用視覺世界典範及視聽作業的眼動表現進一步探討上述議題，探究中文口語字彙辨識之聲調與音段激發與競爭的時序歷程。本計劃第一年共進行兩個實驗，檢驗中文音節聲調鄰項個數大小、及不同聲調對比在音節之激發競爭歷程中所扮演的角色。研究結果顯示：當最小配對音節有四種可能聲調時，或共享聲調的調形時的競爭效果最大，支持中文音節之聲調鄰項個數大小、及中文音節之聲調的調形等訊息，會影響中文口語字彙的處理與辨識。第二年進行兩個實驗，從探討音節為單位轉向探討以音段為單位的激發與競爭，進一步探討聲調在音段的激發競爭歷程中所扮演的角色。研究結果顯示：當目標字與競爭字起始音段相同，不管目標字與競爭字聲調相同或不同都有顯著的競爭效果，雖然起始音段的競爭效果在目標字與競爭字聲調相同時較強。而當目標字與競爭字末段音段相同時，僅聲調相同時有競爭效果。此結果支持起始音高對於音段的激發與競爭有較顯著的影響，不同於共享聲調的調形對於音節的競爭效果有較顯著的影響。第三年則主要檢驗隊列密度(cohort density)，亦即起始音段鄰項個數大小的效果。第三年的兩個實驗同時操弄音段鄰項個數大小，及分別操弄目標項與其隊列競爭者是相同的聲調或不同的聲調，進一步檢驗聲調是否與音段結合用以激發同聲調的隊列競爭者。關於隊列效果，研究結果顯示：在聲調相同的情境下，音段鄰項個數多的目標項，在聽覺目標呈現300~400毫秒之後，有較少的凝視比例而使之不利於激發競爭。而在聲調不同的情境下，音段鄰項個數多的隊列競爭者，在聽覺目標呈現200~300毫秒之後，有較多的凝視比例而有助於激發競爭。這些研究結果支持起始音段鄰項個數大小會影響音段激發競爭的歷程，但是音段鄰項個數大小效果在隊列競爭者同聲調或不同聲調的情境下效果不同。在相同聲調的情境下，音段鄰項個數少的目標項占優勢；但在不同聲調的情境下，音段鄰項個數多的隊列競爭者占優勢。
    This project aims at investigating the time course of lexical activation and competition in Chinese spoken word recognition, inferred by the eye movements in a looking-while-listening task. Four years of experiments are proposed to examine the roles of tonal and segmental information of Chinese monosyllables and disyllable words in activating lexical representations when the auditory stream unfolds over time. All the experiments adapt the visual world paradigm that eye movements to an array of four Chinese characters on a screen are recorded as the participants listened a spoken instruction followed by a target. Fixation proportions on target and competitors that share segmental and/or tonal information with target are analyzed and compared in the consecutive time periods after the acoustic onset of the targets. In the first year, three experiments will be conducted to examine the influence of segmental-tonal neighborhood density on the time course of lexical activation and competition of processing Chinese spoken words. In the second year, three experiments are designed to test segmental activation and competition interacting with tone for monosyllables. In the third year, four experiments will be conducted to examine the time course of cohort and rhyme density effects considering tonal information for Chinese monosyllables. In the fourth year, four experiments are designed to test both tonal and segmental activation and competition in the context of Chinese disyllabic words.
