Traditionally, event-related brain potential (ERP) studies of language processing have presented words at a fixed rate using rapid serial visual presentation. Recent studies suggest, however, that the processes engaged during sentence comprehension are contingent on word presentation rate. These findings underscore the importance of allowing participants to read at a natural pace. The present study employed simultaneous self-paced reading and ERP methodologies to examine behavioral and neural responses while participants read sentences containing pragmatic or morphosyntactic violations or no violations. ERP and self-paced reading results replicated previous findings. This novel combination of behavioral and ERP methodologies combines the high temporal resolution and direct neural measures offered by ERPs with the more natural reading environment and information about processing load provided by self-paced reading.
传统上,语言加工的事件相关脑电位(ERP)研究使用快速序列视觉呈现以固定速率呈现单词。然而,最近的研究表明,句子理解过程中涉及的加工过程取决于单词呈现速率。这些发现强调了让参与者以自然速度阅读的重要性。本研究采用同步自定步速阅读和ERP方法,在参与者阅读包含语用或形态句法违反或无违反情况的句子时,检查行为和神经反应。ERP和自定步速阅读结果重复了先前的发现。这种行为和ERP方法的新颖结合,将ERP提供的高时间分辨率和直接神经测量与自定步速阅读提供的更自然阅读环境和加工负荷信息结合起来。
