This study investigates brain potentials to derived word forms in Spanish. Two experiments were performed on derived nominals that differ in terms of their productivity and semantic properties but are otherwise similar, an acceptability judgment task and a reading experiment using event-related brain potentials (ERPs) in which correctly and incorrectly formed derived words were presented in sentence contexts. The first experiment indicated productivity differences between the different nominalization processes in Spanish. The second experiment yielded a pattern of ERP responses that differed from both the familiar lexical-semantic and grammatical ERP effects. Violations of derivational morphology elicited an increased N400 component plus a late positivity (P600), unlike gender-agreement violations, which produced the biphasic LAN/P600 ERP pattern known from previous studies of morpho-syntactic violations. We conclude that the recognition of derived word forms engages both word-level (lexical-semantic) and decompositional (morpheme-based) processes.
本研究调查了西班牙语中派生词形式的脑电位。进行了两项实验，涉及到在生产性和语义属性方面存在差异但在其他方面相似的派生词名词，一个是可接受性判断任务，另一个是使用事件相关脑电位 (ERP) 的阅读实验，其中在句子语境中呈现了正确和不正确形成的派生词。第一个实验表明了西班牙语中不同名词化过程之间的生产性差异。第二个实验产生了一种与熟悉的词汇语义和语法 ERP 效应都不同的 ERP 响应模式。与性别一致的违反不同，违反派生形态会引起 N400 成分的增加和正性后电位 (P600)，而不是从先前关于形态句法违反的研究中已知的双相 LAN/P600 ERP 模式。我们得出结论，派生词形式的识别既涉及词级（词汇语义）又涉及分解（基于词素）过程。
