Little is known about the relationship of reading speed and early visual processes in normal readers. Here we examined the association of the early P1, N170 and late N1 component in visual event-related potentials (ERPs) with silent reading speed and a number of additional cognitive skills in a sample of 52 adult German readers utilizing a Lexical Decision Task (LDT) and a Face Decision Task (FDT). Amplitudes of the N170 component in the LDT but, interestingly, also in the FDT correlated with behavioral tests measuring silent reading speed. We suggest that reading speed performance can be at least partially accounted for by the extraction of essential structural information from visual stimuli, consisting of a domain-general and a domain-specific expertise-based portion.
对于正常阅读者的阅读速度与早期视觉过程之间的关系，我们知之甚少。在这里，我们利用词汇判断任务（LDT）和面孔判断任务（FDT），在一个由 52 名德国成年阅读者组成的样本中，检查了视觉事件相关电位（ERP）中早期 P1、N170 和晚期 N1 成分与默读速度以及其他一些认知技能之间的关联。有趣的是，LDT 中的 N170 成分的振幅，以及 FDT 中的振幅，与衡量默读速度的行为测试相关。我们认为，阅读速度的表现至少可以部分归因于从视觉刺激中提取基本的结构信息，这些信息包括一个领域普遍的和一个基于特定领域专业知识的部分。
