Abstract
In a sentence reading ERP study in Swedish we investigated the roles of the N400 and P600 components. By manipulating ease of lexical retrieval and discourse integration of the critical words in four conditions (contextually primed/non-primed and degree of contextual fit), we explored these components from a sentence processing perspective. The results indicate that the N400 indexes lexical retrieval and access of stored conceptual knowledge, whereas the P600 component indexes pragmatic processes, such as integration of a word into the discourse context, or the information structural status of the word. The results support single-stream models of sentence processing where lexical retrieval and integration do not take place in parallel, as in multi-stream models.
期刊介绍：
CORTEX is an international journal devoted to the study of cognition and of the relationship between the nervous system and mental processes, particularly as these are reflected in the behaviour of patients with acquired brain lesions, normal volunteers, children with typical and atypical development, and in the activation of brain regions and systems as recorded by functional neuroimaging techniques. It was founded in 1964 by Ennio De Renzi.
