Abstract
Monitoring is an aspect of executive control that entails the detection of errors and the triggering of corrective actions when there is a mismatch between competing responses or representations. In the language domain, research of monitoring has mainly focused on errors made during language production. However, in language perception, for example while reading or listening, errors occur as well and people are able to detect them. A hypothesis that was developed to account for these errors is the monitoring hypothesis for language perception. According to this account, when a strong expectation conflicts with what is actually observed, a reanalysis is triggered to check the input for processing errors reflected by the P600 component. In contrast to what has been commonly assumed, the P600 is thought to reflect a general reanalysis and not a syntactic reanalysis. In this review, we will describe the different studies that led to this hypothesis and try to extend it beyond the language domain.
