个体在心理语言变量预测他们对词汇处理任务的反应的程度上表现出差异。在词汇处理过程中，一个重要的变量是频率，但频率效应的大小已被证明会随着个人词汇量的增加而减小。在大量英语单词上使用三角模型的连接主义计算实现，其中正字法、语音和语义表示在处理过程中相互作用，我们表明该模型显示了由于语言暴露量的减少而导致的频率效应，这个变量也是模型中更大的词汇量的原因。该模型还接受了学习第二语言荷兰语的训练，并复制了行为观察结果，即第二语言熟练程度的提高导致该语言的频率效应降低，但第一语言的频率效应增加。该模型为证明词汇加工个体差异模型中心理语言变量之间的因果关系以及双语对语言加工系统中相互作用变量的影响提供了第一步。
Individuals show differences in the extent to which psycholinguistic variables predict their responses for lexical processing tasks. A key variable accounting for much variance in lexical processing is frequency, but the size of the frequency effect has been demonstrated to reduce as a consequence of the individual’s vocabulary size. Using a connectionist computational implementation of the triangle model on a large set of English words, where orthographic, phonological, and semantic representations interact during processing, we show that the model demonstrates a reduced frequency effect as a consequence of amount of exposure to the language, a variable that was also a cause of greater vocabulary size in the model. The model was also trained to learn a second language, Dutch, and replicated behavioural observations that increased proficiency in a second language resulted in reduced frequency effects for that language but increased frequency effects in the first language. The model provides a first step to demonstrating causal relations between psycholinguistic variables in a model of individual differences in lexical processing, and the effect of bilingualism on interacting variables within the language processing system.
