The timing of our brain waves shapes which words we hear. Researchers used psychophysics, neuroimaging, and computational modeling to test whether neural timing influences perception of more or less frequent speech sounds and words. Neural timing is sensitive to the probability of words vs.
sounds in different brain regions, shaping sound and word recognition.
"We conclude that brain waves provide a temporal structure that enhances the brain's ability to predict and process speech based on the probability of linguistic units," says Ten Oever."Predictable speech sounds and words have a lower threshold for activation, and our brain waves reflect this. Knowledge about how"Our study has important consequences for theories of predictive coding, adds senior author Andrea Martin.
