In order to test recent claims about the structure of verbal working memory, two ERP experiments with Dutch speaking participants were carried out. We compared the ERP effects of syntactic and semantic mid-sentence anomalies in subject and object relative sentences. In Experiment 1, the participants made acceptability judgments, while in Experiment 2 they(More)
Syntactic anomalies reliably elicit P600 effects. Recent studies, however, reported P600 effects to semantic anomalies. These findings are difficult to reconcile with the common view on the P600 as a purely syntactic component. The present study--carried out in Dutch--tested the possibility that a P600 to semantic anomalies would nevertheless reflect(More)
Monitoring refers to a process of quality control designed to optimize behavioral outcome. Monitoring for action errors manifests itself in an error-related negativity in event-related potential (ERP) studies and in an increase in activity of the anterior cingulate in functional magnetic resonance imaging studies. Here we report evidence for a monitoring(More)
In a semantic priming paradigm, the effects of different levels of processing on the N400 were assessed by changing the task demands. In the lexical decision task, subjects had to discriminate between words and nonwords, and in the physical task, subjects had to discriminate between uppercase and lowercase letters. The proportion of related versus unrelated(More)
In the language domain, most studies of error monitoring have been devoted to language production. However, in language perception, errors are made as well and we are able to detect them. According to the monitoring theory of language perception, a strong conflict between what is expected and what is observed triggers reanalysis to check for possible(More)
How are bilinguals able to switch from one language to another? The prevailing inhibition hypothesis takes larger reaction-time (RT) costs for switching to the first language (L1) than to the second language (L2) as evidence for suppression of the non-target language. Switch cost asymmetries can alternatively be explained by an L1-repeat-benefit, assuming(More)
We present evidence for a monitoring process in language perception at the word level, reflected by a P600. This P600 is triggered when a conflict evolves because the brain encounters an unexpected linguistic item when another item is highly expected. To resolve this conflict between representations, the brain monitors the input to check for possible(More)
