The P600 is an event-related potential (ERP), or peak in electrical brain activity measured by electroencephalography (EEG). It is a language-relevant ERP and is thought to be elicited by hearing or reading grammatical errors and other syntactic anomalies.

The N400 and word meaning What is the relevance of the often found N400 component of the ERP in language processing? This seems to reflect lexical-semantic processing when pseudo words are introduced into a sentence or if a word does not fit in a particular context. 2017-04-01 The N400 and P600 are among the most studied electrophysiolo-gical signatures of native language comprehension. The N400 is a negative deflection peaking around 400 ms after stimulus onset that indexes the processing of meaning. A greater N400 amplitude can be elicited by manipulating cloze probability (DeLong et al., 2005; Analysis of EEG and SPECT data showed N400 and P600 event-related potentials (ERPs) particularly evoked by semantic violations in the sentences, and enhanced perfusion in a temporo-frontal network during task compared to rest, involving the auditory cortex bilaterally and Broca's area. EEG studies including semantic expectancy violations have mainly reported modulations of the N400 event-related-potential (ERP), linked to semantic processing, and the P600 ERP linked to syntactic For the N400, the negative deflection of positive words is the largest, while that of the neutral words is the smallest in frontal-central areas.

Although there have been some studies (e.g. Kim & Osterhout 2005) claiming a semantic P600. These are the grand average event-related potentials to ungrammatical, semantically incongruous, and comparable grammatical/congruous sentence final words. Se hela listan på psychology.wikia.org The P600 used to be understood in the processing of syntactic speech error. However, listening to more complex sentences also increases the P600 component. The modern view is that the P600 reflects a more general effect of processing difficulty – no matter whether it is syntactic or semantic. 2017-04-01 · A similar N400-P600 continuum has also been reported in morphosyntactic processing in a study of Japanese native speakers (Tanner et al., 2014).
