Discourse-level semantic coherence influences beta oscillatory dynamics and the N400 during sentence comprehension
Language comprehension discourse semantics beta oscillations

In this study, we used electroencephalography to investigate the influence of discourse-level semantic coherence on electrophysiological signatures of local sentence-level processing. Participants rea...
网络语言的创造性加工过程：新颖N400与LPC
网络语言 创造性思维 N400延迟效应 晚期正成分
2017/3/2
采用事件相关电位(ERP)技术比较在语义违反范式下网络语言和标准汉语的语义加工差异。结果发现：(1)不管是网络语言还是标准汉语, 相对于语义一致条件, 语义不一致条件在400 ms诱发了一个更负的负成分, 但网络语言的经典N400差异波具有更晚的潜伏期和更长的持续时间; (2)溯源结果发现, 网络语言和标准汉语的经典N400差异波的早期和晚期的定位均分别定位于丘脑和前扣带回, 表明N400延迟效应...
THE N400 IS NOT A SEMANTIC ANOMALY RESPONSE: MORE EVIDENCE FROM ADJECTIVE-NOUN COMBINATION
ANOMALY RESPONSE ADJECTIVE-NOUN COMBINATION
2015/9/2
Previous work has shown that the N400 ERP component is elicited by all words, whether
presented in isolation or in structured contexts, and that its amplitude is modulated by
semantic association ...
A cortical network for semantics: (de)constructing the N400
A cortical network N400 response
2015/9/2
Measuring event-related potentials (ERPs) has been fundamental to our
understanding of how language is encoded in the brain. One particular ERP response, the
N400 response, has been especially inf...
A lexical basis for N400 context effects: Evidence from MEG
Semantic priming Semantic anomal Prediction
2015/9/2
The electrophysiological response to words during the ‘N400’ time window (300–500 ms post-onset) is
affected by the context in which the word is presented, but whether this effect reflects the ...
Dissociating N400 Effects of Prediction from Association in Single-word Contexts
Single-word Contexts Association
2015/9/2
When a word is preceded by a supportive context such as a
semantically associated word or a strongly constraining sentence
frame, the N400 component of the ERP is reduced in amplitude.
The balance between memory and unification in semantics: A dynamic account of the N400
Semantics Neuroscience N400.
2015/4/10
At least three cognitive brain components are necessary in order for us to be
able to produce and comprehend language: a Memory repository for the
lexicon, a Unification buffer where lexical informa...
The interaction of discourse context and world knowledge in online sentence comprehension: Evidence from the N400
discourse context world knowledge
2015/3/31
In an ERP experiment we investigated how the recruitment and integration of world knowledge information relate to the integration of information within a current discourse context. Participants were p...
