Nouns in a predictive and prime control context. Grand average ERPs elicited by the critical nouns in a predictive context and prime control context over the midline electrodes. Black lines represent the ERP to the predicted nouns; red lines represent the ERP to unexpected but still congruent nouns. The ERPs are timelocked to the onset of the noun, and are filtered (4 Hz high cut-off, 48 dB/oct) for presentation purposes only.
