N400 and category exemplar associative strength

International Journal of Psychophysiology, 2005
The main purpose of this study was to examine if the N400 amplitude can be considered an index of category exemplar strength of association in a semantic categorization task. Series of six words from a particular semantic category were used as context, and the strength of association between the seventh word and the category was manipulated.

N400 and LPP in spontaneous trait inferences

Brain Research, 2011
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.

The neurocognitive basis of metamemory: Using the N400 to study the contribution of fluency to judgments of learning.

Neurobiology of Learning and Memory, 2020
Metamemory is crucial for monitoring, evaluating, and optimizing memory performance, but to date its basis is controversial. In the present study, we examined the contribution of processing fluency-the ease of processing information during learning-to ...

Informative use of “not” is N400‐blind

Psychophysiology, 2020
AbstractWhile sentence processing is generally a highly incremental and predictive process, negation seems to present an exception to this generalization. Two‐step models of negation processing claim that predicate negation is computed only after the meaning of the core proposition has been computed.

Early N400 development and later language acquisition

Psychophysiology, 2006
AbstractRecent developmental research on word processing has shown that mechanisms of lexical priming are already present in 12‐month‐olds whereas mechanisms of semantic integration indexed by the N400 mature a few months later. In a longitudinal setting we investigated whether the occurrence of an N400 at 19 months is associated with the children's ...

Narrowed Expectancies under Degraded Speech: Revisiting the N400

Journal of Cognitive Neuroscience, 2013
AbstractUnder adverse listening conditions, speech comprehension profits from the expectancies that listeners derive from the semantic context. However, the neurocognitive mechanisms of this semantic benefit are unclear: How are expectancies formed from context and adjusted as a sentence unfolds over time under various degrees of acoustic degradation ...

Social conflicts elicit an N400-like component

Neuropsychologia, 2014
When people have different opinions, they often adjust their own attitude to match that of others, known as social conformity. How social conflicts trigger subsequent conformity remains unclear. One possibility is that a conflict with the group opinion is perceived as a violation of social information, analogous to using wrong grammar, and activates ...

N400 to Semantically Anomalous Pictures and Words

Journal of Cognitive Neuroscience, 1992
Abstract The N400 component of the human event-related brain potential appears to be related to violations of semantic expectancy during language comprehension. The present experiment investigated whether the N400 is related specifically to activity in a language system or is an index of a conceptual system that is accessed by both ...

N400 predicts recovery from disorders of consciousness

Annals of Neurology, 2013
ObjectivePatients 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

The N400 event-related brain potential response: A window on deficits in predicting meaning in schizophrenia.

International Journal of Psychophysiology, 2019
Schizophrenia is characterized by impairments in using past experience to predict what will happen next, at multiple levels of cognitive processing. The N400 event-related brain potential (ERP) waveform indexes our ability to use contextual information ...
