Fig. 3.

(a) Grand average ERPs (all ROIs) following statements (blue) and questions (red). The time windows with a main effect of prosody are indicated by a rectangle (from left to right: N1, prosodic expectancy positivity (‘PEP’), and P600). The difference scalp maps represent statements subtracted from questions, averaged across participants and electrodes. The grand average ERPs are displayed separately for the four ROIs in: (b) LA (left anterior), (c) RA (right anterior), (d) LP (left posterior) and (e) RP (right posterior); (f) Mean amplitudes averaged over the ROIs of anterior (light green) and posterior (dark green) electrode sites within the P600 time window in all four conditions. Error bars represent ±1 standard error mean (SEM). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
