这项研究调查了一组 7 岁儿童的言语感知和词汇信息之间的相互作用，其中 26 名阅读能力较差，36 名阅读能力良好。在评估阅读技能和语音意识的任务中检查了孩子们的表现。伪词重复和音素识别。尽管优秀的读者在 /bif/-/pif/ 和 /bis/-/pis/ 连续体的音素识别任务中表现出明确定义的类别感知，但 /bif/-/pif/ 的类别边界比 /bis/-/pis/ 的边界更长。这是经典词汇效应的特征。较差的读者在这两个连续体上都表现出不太明确的分类感知。尽管阅读能力差的人没有表现出经典的词汇效应，但词汇确实影响了每个 VOT 中音素被识别为 /b/ 或 /p/ 的总体比率。这些发现表明，词典可能作为解决言语感知中歧义的补偿机制。此外，对音素识别中的群体差异进行统计校正使得音素删除中的群体差异消失，这表明言语感知的缺陷可能在与阅读失败相关的语音核心缺陷中发挥因果作用。 (C) 2001 年学术出版社。
This study examined the interaction between speech perception and lexical information among a group of 7-year-old children, of which 26 were poor readers and 36 were good readers. The children's performance was examined on tasks assessing reading skill, phonological awareness. pseudoword repetition, and phoneme identification. Although good readers showed clearly defined categorical perception in the phoneme identification task for both the /bif/-/pif/ and the /bis/-/pis/ continua, the category boundary for /bif/-/pif/ was at longer VOTs than the boundary for /bis/-/pis/. which characterizes the classic lexicality effect. Poor readers showed less sharply defined categorical perception on both continua. Although poor readers did not show the classic lexicality effect, lexicality did affect the overall rate with which phonemes were identified as /b/ or /p/ at each VOT. These findings suggest that the lexicon may operate as a compensatory mechanism for resolving ambiguities in speech perception. Furthermore, statistical correction for group differences in phoneme identification made group differences in phoneme deletion disappear, suggesting that deficits in speech perception may play a causal role in the phonological core deficit associated with reading failure.
