This study investigated whether individual differences in vocabulary size, speech perception and production, and nonword repetition in 2½ to 3-year-old children predicted phonological awareness two years later. One hundred twenty-two children were tested twice. During the first testing period, we measured children's receptive vocabulary, speech perception, nonword repetition, and articulation. At the second testing period, we measured children's phonological awareness. The best predictors of phonological awareness at age 5 were receptive vocabulary and a measure of phonological processing derived from performance on the nonword repetition task. The results of this study suggest that nonword repetition accuracy can be used to index implicit phonological awareness at an age when children are too young to perform explicit phonological awareness tasks reliably.
本研究调查了2.5至3岁儿童在词汇量、言语感知与产出以及非词重复方面的个体差异是否能预测两年后的语音意识。122名儿童接受了两次测试。在第一次测试期间，我们测量了儿童的接受性词汇、言语感知、非词重复和发音。在第二次测试期间，我们测量了儿童的语音意识。5岁时语音意识的最佳预测指标是接受性词汇以及从非词重复任务表现中得出的语音加工指标。本研究结果表明，在儿童年龄太小而无法可靠地完成显性语音意识任务时，非词重复准确性可用于衡量隐性语音意识。
