汉语词汇习得的年龄效应：语义假设的证据

Age of Acquisition Effects in Reading Chinese: Evidence in Favor of the Semantic Hypothesis

通过三个实验考察了词汇加工中的习得年龄效应。实验一对比了汉字命名和图片命名中词汇习得的年龄效应，发现图片命名中存在着较大的词汇习得的年龄效应，汉字命名中没有出现这种效应。实验二和实验三分别采用语义范畴判断任务和图片语义分类任务，两个实验均发现了词汇习得的年龄效应。实验结果说明，词汇习得的年龄效应至少部分来源于语义加工的层次，结果支持了语义假设的观点。

Age of acquisition (AoA) is an important variable that has recently drawn considerable attention as a determinant of lexical processing. Several hypotheses have been advanced to explain the origin of the AoA effects. One of the hypotheses is the phonological completeness hypothesis， which assumes that AoA effects arise at the level of phonological representation (Brown & Watson， 1987; Gerhand & Barry， 1998). However， it had failed to explain the AoA effects in a phonological segment experiment (
