Kim & Osterhout 2005) claiming a semantic P600. level 2 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. These EEG waves are called the P100, the N400, and the P600.

What is more, none of the models can account for isolated P600 effects in a larger discourse. Nieuwland and van Berkum (2005), for instance, presented participants with short stories, like a story about a tourist checking Our main objectives were to test if abnormalities of the N400 or Late Positive Component (LPC, P600) were associated with a left temporal seizure focus, or left temporal lobe dysfunction.

Dit is een woord dat qua betekenis afwijkt van de strekking van een zin waarin dit woord is ingebed. De N400 is een component van de ERP waaraan zeer veel publicaties zijn zunächst grob auf die Methode der Elektroenzephalographie (EEG) und die bereits untersuchten sprachbezogenen ereigniskorrelierten Potenziale (EKPs) eingegangen (Kapitel 2). Darin werden vor allem Studien zu der hier im Fokus stehenden N400-Komponente vorgestellt, bevor sie von anderen EKPs (P600, ELAN und LAN) abgegrenzt wird. その他、特に神経言語学研究でよく使われる ERP には ELAN、N400、P600/SPS がある。 関連項目. 脳波; ニューロコミュニケーター:P300を利用したBMI; N400 (神経科学) 関連文献.

2013-12-31 · In EEG, N400 effects for picture targets have been observed –, and are not qualitatively or quantitatively very different from word-based responses. While there might be slight topographical differences depending on the stimulus format, there is certainly no reason to assume that the N400 effect is specific to a particular format or sensory modality [4] .
