The high and low comprehensibility groups exhibit N2 component amplitude. Different colors are used to distinguish varying levels of information comprehensibility and consistency. The horizontal axis represents time, while the vertical axis depicts the potential amplitude. The light gray section illustrates the trend of intelligibility and consistency for different information over time, at six electrode points (F1, FZ, F2, FC1, FCZ, FC2) within the 220–320 millisecond time window.
