Semantics and N400: insights for schizophrenia

open access: yesJournal of Psychiatry and Neuroscience, 2004
Thought disorder is a hallmark symptom of schizophrenia, which often leads to deficits in social functioning. Some aspects of this cognitive dysfunction are the result of abnormal characteristics in the semantic processes of patients. These abnormalities exist not only at the discourse production level, but at the discourse comprehension level as well.

The interplay between domain-general and domain-specific mechanisms during the time-course of verbal associative learning: An event-related potential study

open access: yesNeuroImage, 2021
Humans continuously learn new information. Here, we examined the temporal brain dynamics of explicit verbal associative learning between unfamiliar items.

The N400 and the fourth grade shift [PDF]

open access: yesDevelopmental Science, 2014
AbstractWhile behavioral and educational data characterize a fourth grade shift in reading development, neuroscience evidence is relatively lacking. We used the N400 component of the event‐related potential waveform to investigate the development of single word processing across the upper elementary years, in comparison to adult readers.

Multimodal characterization of the semantic N400 response within a rapid evaluation brain vital sign framework

open access: yesJournal of Translational Medicine, 2018
Background For nearly four decades, the N400 has been an important brainwave marker of semantic processing. It can be recorded non-invasively from the scalp using electrical and/or magnetic sensors, but largely within the restricted domain of research ...

The N400 for brain computer interfacing: complexities and opportunities [PDF]

open access: yesJournal of Neural Engineering, 2020
Abstract The N400 is an event related potential that is evoked in response to conceptually meaningful stimuli. It is for instance more negative in response to incongruent than congruent words in a sentence, and more negative for unrelated than related words following a prime word.

Processing of semantic incongruency at the onset of sleep: An auditory N400 evoked potential study. [PDF]

open access: yes, 2023
The ability to organize self-generated thought into coherent, meaningful semantic representations is a central aspect of human cognition and undergoes regular alterations throughout the day.

Eye-movements and ERPs reveal the time course of processing negation and remitting counterfactual worlds [PDF]

open access: yes, 2008
The ability to update our current knowledge using contextual information is a vital process during every-day language comprehension. To understand a negated statement, readers are required to cancel real-world expectations, but are not explicitly ...

Event-related brain potential evidence for animacy processing asymmetries during sentence comprehension [PDF]

open access: yes, 2013
The animacy distinction is deeply rooted in the language faculty. A key example is differential object marking, the phenomenon where animate sentential objects receive specific marking.

Effects of Dispositional Affect on the N400: Language Processing and Socially Situated Context

open access: yesFrontiers in Psychology, 2021
We examined whether the N400 Event-Related Potential (ERP) component would be modulated by dispositional affect during sentence processing. In this study, 33 participants read sentences manipulated by direct object type (congruent vs.

N400 and semantic categorization in schizophrenia

open access: yesBiological Psychiatry, 1991
The N400 component of event-related potentials (ERPs) was investigated in medicated schizophrenic patients and normal controls in a semantic categorization task. The subjects' task was to indicate whether pairs of words were semantically related or unrelated.
