The proposal of a general conflict resolution mechanism in lIFG was investigated further in relation to language errors. In an fMRI study participants read sentences containing syntactic and plausibility violations. Furthermore, they were presented with sentences that were difficult to comprehend, due to degradation of the bottom-up signal (i.

When a strong conflict is present this functions as a bottom-up signal to bias attention towards the unexpected representation for reprocessing to check for possible processing errors. This monitoring process, encompassing both the conflict and reprocessing, is thought to be reflected in the late positivity or P600 effect.

This monitoring process is thought to be reflected by the P600 component in the EEG. The present study further investigated this monitoring process by comparing syntactic and spelling violations in an EEG and an fMRI experiment.

Ellipses are syntactic frames in which slots for grammatical morphology tend to be lacking (e.g.

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 perceptual errors, a process reflected by the P600.

On the basis of these findings, several investigators propose the P600 effect to reflect syntactic repair or syntactic restructuring. According to our Monitoring Theory the P600 effect reflects more general sentence reanalysis, to check whether the input sentence has been perceived appropriately.

Such new meanings cannot be retrieved from memory but still have to be constructed. The goals of this article were: first, to explore the nature of new meaning creation, and second, to test abstract symbol theories against embodied theories of meaning.

View Article and Find Full Text PDFWe 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 processing errors.

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 process in perception, in particular, language perception, manifesting itself in a late positivity in the ERP.

How fast are we in accessing world knowledge? In two experiments, we tested for priming for word triplets that described a conceptual script (e.g., DIRECTOR-BRIBE-DISMISSAL) but were not associatively related and did not share a category relationship.

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 read for comprehension.

Little is known about the role of the magno system in reading. One important hypothesis is that this system is involved in the allocation of attention. We reasoned that the presentation of a single letter automatically draws attention to this letter, whereas in the case of a flanked letter, an additional process of attention allocation is required for identification to occur.
