Three hypotheses for effects of age of acquisition (AoA) in lexical processing are compared: the cumulative frequency hypothesis (frequency and AoA both influence the number of encounters with a word, which influences processing speed), the semantic hypothesis (early-acquired words are processed faster because they are more central in the semantic network), and the neural network model (early-acquired words are faster because they are acquired when a network has maximum plasticity). In a regression study of lexical decision (LD) and semantic categorization (SC) in Italian and Dutch, contrary to the cumulative frequency hypothesis, AoA coefficients were larger than frequency coefficients, and, contrary to the semantic hypothesis, the effect of AoA was not larger in SC than in LD. The neural network model was supported.
本文比较了词汇加工中习得年龄(AoA)效应的三种假说:累积频率假说(频率和AoA都影响一个单词的接触次数,进而影响加工速度)、语义假说(早期习得的单词加工速度更快,因为它们在语义网络中更核心)和神经网络模型(早期习得的单词速度更快,因为它们是在网络具有最大可塑性时习得的)。在一项针对意大利语和荷兰语的词汇判断(LD)和语义分类(SC)的回归研究中,与累积频率假说相反,AoA系数大于频率系数,并且与语义假说相反,AoA在SC中的效应并不比在LD中更大。神经网络模型得到了支持。
