Electrocortical 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...
متن کاملTesting an associative account of semantic satiation.
How is the meaning of a word retrieved without interference from recently viewed words? The ROUSE theory of priming assumes a discounting process to reduce source confusion between subsequently presented words. As applied to semantic satiation, this theory predicted a loss of association between the lexical item and meaning. Four experiments tested this explanation in a speeded category-matchin...
متن کاملN400 as an index of semantic expectancies: differential effects of alcohol and cocaine dependence.
BACKGROUND Chronic substance abuse has been associated with decrements in the processing and expression of language. The present study utilized the N400 event-related electroencephalographic potential to index semantic processing in 133 adults with (n=49) or without (n=84) a history of alcohol and/or cocaine dependence. The contributions of age, gender, and comorbid marijuana and nicotine depen...
متن کاملN400 effects of semantic richness can be modulated by task demands.
Semantic richness is a multidimensional construct that can be defined as the amount of semantic information associated with a concept. OBJECTIVE To investigate neurophysiological correlates of semantic richness information associated with words and its interaction with task demands. METHOD Two different dimensions of semantic richness (number of associates and number of semantic neighbors) ...
متن کاملBefore the N400: effects of lexical-semantic violations in visual cortex.
There exists an increasing body of research demonstrating that language processing is aided by context-based predictions. Recent findings suggest that the brain generates estimates about the likely physical appearance of upcoming words based on syntactic predictions: words that do not physically look like the expected syntactic category show increased amplitudes in the visual M100 component, th...
