不同阅读理解能力的成年人学习了一组以前未知的罕见英语单词（例如，在三种不同的学习条件下，其中文字知识的类型被操纵。这些词在三种情况下呈现：（1）正字法到意义（无音韵）;（2）正字法到音韵（无意义）;（3）音韵到意义（无正字法）。学习后，被试对所学单词、熟悉的已知单词和未呈现的（未学习的）稀有单词进行意义判断，同时记录他们的ERP。行为研究结果显示，理解技能对意义判断绩效没有显著影响。相比之下，ERP结果表明理解技能的差异P600振幅;高技能的读者表现出更强的熟悉效果的学习单词，而技能较低的读者没有区分学习单词，熟悉的单词，和未学习的单词。来自P600和N400的证据表明，当意义信息与正字法而不是语音相结合时，意义的上级学习。这些结果表明，在学习单词知识（正字法，音韵，意义）的可用性会影响随后的单词识别过程中遇到的话在一个新的上下文中。
Adults of varying reading comprehension skill learned a set of previously unknown rare English words (e.g., gloaming) in three different learning conditions in which the type of word knowledge was manipulated. The words were presented in one of three conditions: (1) orthography-to-meaning (no phonology); (2) orthography-to-phonology (no meaning); and (3) phonology-to-meaning (no orthography). Following learning, participants made meaning judgments on the learned words, familiar known words, and unpresented (unlearned) rare words while their ERPs were recorded. The behavioral results showed no significant effects of comprehension skill on meaning judgment performance. Contrastingly, the ERP results indicated comprehension skill differences in P600 amplitude; high-skilled readers showed stronger familiarity effects for learned words, whereas less-skilled readers did not distinguish between learned words, familiar words, and unlearned words. Evidence from the P600 and N400 illustrated superior learning of meaning when meaning information was coupled with orthography rather than phonology. These results suggest that the availability of word knowledge (orthography, phonology, and meaning) at learning affects subsequent word identification processes when the words are encountered in a new context.
