The N400 event-related potential in aphasia.
Although the N400 component of event-related potentials (ERPs) is suggested to reflect language processing, exactly which language processing functions N400 is sensitive to is not clear. We investigated this component in aphasic patients with some impairments of language processing. Meaningful and meaningless words in Kana (Japanese characters) were used as stimuli under a visual oddball paradi...
متن کاملParafoveal N400 effect during sentence reading.
Research has suggested that during reading, parafoveal information pertaining to the next word in a line might be, at least partially, processed. We used event-related brain potentials (ERPs) to examine this issue. Volunteers read sentences presented word-by-word at fixation with each word flanked bilaterally on its right by the next word in the sentence and on its left by the preceding word. I...
متن کاملN400 and LPP in spontaneous trait inferences.
Past research on spontaneous trait inferences using event related potentials (ERPs) has consistently reported increased late positive potential (LPP) amplitudes following social expectancy violations, but no N400 modulation. In the present study, participants read scenarios describing behaviors of unknown actors. They entailed descriptions of several positive trait implying behaviors, followed ...
متن کاملN400 predicts recovery from disorders of consciousness.
OBJECTIVE Patients with the unresponsive wakefulness syndrome (UWS; formerly vegetative state) or in a minimally conscious state (MCS) open their eyes spontaneously but show no (UWS) or only marginal (MCS) signs of awareness. Because these states can become permanent, residual information processing capacities need to be determined, and reliable outcome predictors need to be found. We assessed ...
متن کاملElectrocortical N400 Effects of Semantic Satiation
Semantic satiation is characterised by the subjective and temporary loss of meaning after high repetition of a prime word. To study the nature of this effect, previous electroencephalography (EEG) research recorded the N400, an ERP component that is sensitive to violations of semantic context. The N400 is characterised by a relative negativity to words that are unrelated vs. related to the sema...
