An event-related potential (ERP) technique was used to investigate the way in which noun–noun compounds are processed during a lexical decision task with Italian speakers. Reaction times and error rates were higher for compounds than for noncompounds. ERP data showed a more negative peak in the left anterior negativity (LAN) component for compounds. These results are compatible with a dual-route model that posits not only whole-word access for compounds but also an activation of decomposed representations of compound constituents. A final result relates to head position, which in Italian compounds could be on either the left- or the right-hand side of the word. While behavioural analysis did not reveal a difference between left- and right-headed compounds, a difference was found with the P300 component. The role of the compound head as a crucial information-bearing component is discussed.

意大利名义化合物的神经相关性和头晕效应的潜在影响：一项 ERP 研究

事件相关电位 (ERP) 技术被用于研究名词-名词复合词在与意大利语使用者的词汇决策任务中的处理方式。化合物的反应时间和错误率高于非化合物。ERP 数据显示化合物的左前阴性 (LAN) 成分的负峰更大。这些结果与双路径模型兼容，该模型不仅假定复合词的全词访问，而且还假定复合成分的分解表示的激活。最终结果与头部位置有关，在意大利语复合词中，头部位置可以位于单词的左侧或右侧。虽然行为分析没有揭示左头和右头化合物之间的差异，但发现 P300 组件存在差异。
