基于Rescorla-Wagner模型（Danks，2003）的平衡方程，提出了一个2层符号网络模型。本研究首先在塞尔维亚语中进行了两个实验，揭示了米林，Filipovic Durdevic和Moscoso del普拉多Martin（2009）在非启动词汇判断中观察到的屈折聚合效应。经验的结果是成功地建模，而不必假设单独的表示，如曲折或数据结构的曲折范例。在下一步中，相同的朴素判别学习方法与形态学处理文献中记载的各种效果进行比较。复杂单词和短语的频率效应（Arnon & Snider，2010）出现在模型中，而不存在整个单词或整个短语的表征。家族规模效应（Moscoso del普拉多Martin，Bertram，Haikio，Schreuder，& Baayen，2004; Schreuder & Baayen，1997）出现在简单词、派生词和复合词的模拟中，没有派生词或复合词被表示为这样。研究表明，对于伪派生词，不需要Rastle，Davis和New（2004）提出的特殊形态-正字法分割机制。该模型还复制了Plag和Baayen（2009）的发现，即平均而言，具有更多生产性词缀的单词引起更长的反应延迟;同时，它预测生产性词缀为新单词提供更快的反应延迟。英语短语的聚合效应调节孤立词阅读的报告和建模，表明聚合效应的塞尔维亚语的情况拐点具有跨语言的范围。
A 2-layer symbolic network model based on the equilibrium equations of the Rescorla-Wagner model (Danks, 2003) is proposed. The study first presents 2 experiments in Serbian, which reveal for sentential reading the inflectional paradigmatic effects previously observed by Milin, Filipovic Durdevic, and Moscoso del Prado Martin (2009) for unprimed lexical decision. The empirical results are successfully modeled without having to assume separate representations for inflections or data structures such as inflectional paradigms. In the next step, the same naive discriminative learning approach is pitted against a wide range of effects documented in the morphological processing literature. Frequency effects for complex words as well as for phrases (Arnon & Snider, 2010) emerge in the model without the presence of whole-word or whole-phrase representations. Family size effects (Moscoso del Prado Martin, Bertram, Haikio, Schreuder, & Baayen, 2004; Schreuder & Baayen, 1997) emerge in the simulations across simple words, derived words, and compounds, without derived words or compounds being represented as such. It is shown that for pseudo-derived words no special morpho-orthographic segmentation mechanism, as posited by Rastle, Davis, and New (2004), is required. The model also replicates the finding of Plag and Baayen (2009) that, on average, words with more productive affixes elicit longer response latencies; at the same time, it predicts that productive affixes afford faster response latencies for new words. English phrasal paradigmatic effects modulating isolated word reading are reported and modeled, showing that the paradigmatic effects characterizing Serbian case inflection have crosslinguistic scope.
