Reading senseless sentences: brain potentials reflect semantic incongruity
作者： M Kutas , S. Hillyard

摘要: In a sentence reading task, words that occurred out of context were associated with specific types of event-related brain potentials. Words that were physically aberrant (larger than normal) elicited a late positive series of potentials, whereas semantically inappropriate words elicited a late negative wave (N400). The N400 wave may be an electrophysiological sign of the" reprocessing" of semantically anomalous information.
