Brain responses to different different levels of linguistic unexpectedness (IMAGE)
Caption
Brain responses to different different levels of linguistic unexpectedness, recorded during listening to audiobooks. Researchers quantified how the brain response was modulated by the unexpectedness of the syntactic category (red), of the word meaning (blue), and of the individual speech sounds (green). This revealed dissociable brain responses, in space and time, in both the EEG (left column) and MEG experiment (right column). This indicates that the brain spontaneously predicts upcoming language at multiple levels of abstraction. Lines indicate average effect (coefficient) over time; shaded area indicate bootstrapped standard errors (EEG) or absolute deviation (MEG). Highlighted areas with asterisks indicate extent of statistically significant cluster in the EEG participants.
