Fig. 5

Amplitude of N450 component in consistent and inconsistent conditions for high and low comprehensibility groups. Different colors are utilized to differentiate varying levels of information comprehensibility and consistency. The horizontal axis signifies time, whereas the vertical axis represents the potential amplitude. The light gray section depicts the trend in intelligibility and consistency of various information over time, recorded at six electrode points (F1, FZ, F2, FC1, FCZ, FC2) during the 400–500 millisecond time window.
