摘　　要：本文针对29名高水平晚双语者,采用同韵判断范式,对比分析了他们在识别高频、强规则性和强词汇性真词的语音时,与假词和对照字符在正确率和反应时上所表现出来的差异,并以此为基础,探讨了他们的二语神经认知体系构建现状,阐释了形成语音识别差异和神经认知体系构建现状的原因。本文所得基本结论如下:(1)高水平的晚双语者,即使与二语接触量较大,其语音识别仍然采用效率较低的合成方式;(2)他们的二语水平尚未到达二语本族人的母语水平,其二语神经认知体系仍然处于动态发展之中。The accuracy and response time in judging the rhymes of real-word pairs, pseudoword pairs and control-letter pairs were compared among 29 late bilinguals presumably with high proficiency, the real-word pairs being of high frequency, regular grapheme-phoneme correspondence and high lexicality. Along with the comparison, this paper also explored the structuring state of L2 neurocognitive system of these bilinguals, and the reasons for the differences in rhyme judging and the structuring state of L2 neurocognitive system. Follow- ing conclusions were derived： （1） the late bilinguals, with high proficiency and high exposure, apply but an assembled low-efficiency method to grapheme-phoneme recognition; （2） the L2 proficiency of these bilinguals is nowhere close to that of the native speakers, and their L2 neurocognitive system is still under way of construction.
