摘　　要：12个月婴儿能否表征母语的音位语义特性(phonological specificity)是资源有限理论和表征不连续理论争议的焦点。本研究通过跨通道注视偏好范式(IPLP),对熟悉词进行正确命名和声调错读2种任务,发现不论任务以何种先后顺序呈现,12个月中国婴儿都在正确命名时出现命名效应,在声调错读时出现错读效应。这表明12个月中国婴儿能表征普通话声调的语义特性,资源有限理论适用于声调。By about 12 months of age, infants show sensitivity to mispronunciations of familiar words when asked to identify a referent. These findings indicate that infants are able to access the phonological detail of words when engaged in lexical recognition. However, most of this work has focused on mispronunciations of consonants and vowels. Very little is known about the role that lexical tones play in constraining lexical access during the early stages of lexical development. In tonal languages （e.g., Chinese）, over and above vowel and consonant variations, words are distinguished by lexical tone. Over half the world＇s population speak a tonal language. The current study aims to answer the question： Do Chinese infants treat tones as phonological information in their lexical representations as early as 12 months old？ Using the intermodal preferential looking paradigm with the mispronunciation task, the current study examined whether Chinese infants at 12 months were sensitive to mispronunciations of lexical tones in monosyllabic, familiar words. 12 infants were in groupl, 8 infants were in group2. For group 1, the familiar words were pronounced correctly in blockl, while mispronounced with the falling tone in Mandarin （Tone 4） in block 2. The block order was reversed for the infants in group 2. The proportion of target look （PTL） and the difference between infants＇ longest look at target and distracter images （LLD） before and after naming were calculated. Systematic increment in PTL or LLD across pre- and post-naming phases indicates infants＇ association of the target label and object. The results showed that both groups of infants could associate the target labels and objects when the labels were correctly pronounced （PTL： group 1, t（11） --- 1.78, p = 0.103; group 2, t（7） = 2.95, p = 0.021）, while the associations were not found when the labels were mispronounced （PTL： group 1, t（11） = -0.79, p = 0.45; group 2, t（7） = -0.41, p = 0.70）. In other words, the mispro
