AB The acquisition of new vocabulary is usually mediated by previous experience withlanguage. In the visual domain, the representation of orthographically unfamiliar words at thephonological or conceptual levels may facilitate their orthographic learning. The neural correlates ofthis advantage were investigated by recording EEG activity during reading novel and familiar wordsacross three different experiments (n = 22 each), manipulating the availability of previous knowledgeon the novel written words. A different pattern of event-related potential (ERP) responses wasfound depending on the previous training, resembling cross-level top-down interactive effects duringvocabulary acquisition. Thus, whereas previous phonological experience caused a modulation at thepost-lexical stages of the visual recognition of novel written words (~520 ms), additional semantictraining influenced their processing at a lexico-semantic stage (~320 ms). Moreover, early lexicaldifferences (~180 ms) elicited in the absence of previous training did not emerge after both phonologicaland semantic training, reflecting similar orthographic processing and word-form access.
