Pre-Activation Negativity (PrAN) in Brain Potentials to Unfolding Words
نویسندگان
چکیده
We describe an event-related potential (ERP) effect termed the "pre-activation negativity" (PrAN), which is proposed to index the degree of pre-activation of upcoming word-internal morphemes in speech processing. Using lexical competition measures based on word-initial speech fragments (WIFs), as well as statistical analyses of ERP data from three experiments, it is shown that the PrAN is sensitive to lexical competition and that it reflects the degree of predictive certainty: the negativity is larger when there are fewer upcoming lexical competitors.

Forehearing words: Pre-activation of word endings at word onset
Occurring at rates up to 6-7 syllables per second, speech perception and understanding involves rapid identification of speech sounds and pre-activation of morphemes and words. Using event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI), we investigated the time-course and neural sources of pre-activation of word endings as participants heard the beginning of unfoldin...
متن کاملTone-grammar association within words: Concurrent ERP and fMRI show rapid neural pre-activation and involvement of left inferior frontal gyrus in pseudoword processing
Using a concurrent ERP/fMRI paradigm, we investigated how listeners take advantage of morphologically relevant tonal information at the beginning of words to predict and pre-activate likely word endings. More predictive, low tone word stems gave rise to a 'pre-activation negativity' (PrAN) in the ERPs, a brain potential which has previously been found to increase along with the degree of predic...
متن کاملWord accents and phonological neighbourhood as predictive cues in spoken language comprehension
The present contribution summarises event-related potential (ERP) and functional magnetic resonance imaging (fMRI) findings related to the processing of Swedish word accents in speech comprehension. It has previously been seen that word accents – either a low tone (accent 1) or a high tone (accent 2) on a word stem – can be used to pre-activate suffixes. Furthermore, it has been found that acce...
متن کاملNeural processing of morphosyntactic tonal cues in second-language learners
The morphosyntactic nature of word accents in Swedish makes them a perfect candidate for the study of predictive processing in language. The association of word stem accents with upcoming suffixes allows native listeners to pre-activate a word's potential ending and thereby facilitate speech processing. Unlike native speakers, second language learners are known to be less able to use prediction...
متن کاملThe influence of emotional words on sentence processing: electrophysiological and behavioral evidence.
Whereas most previous studies on emotion in language have focussed on single words, we investigated the influence of the emotional valence of a word on the syntactic and semantic processes unfolding during sentence comprehension, by means of event-related brain potentials (ERP). Experiment 1 assessed how positive, negative, and neutral adjectives that could be either syntactically correct or in...
