EEG signals of different categories (target, target adjoint, and non-target symbol), measured by electrode Pz. (A) The target character corresponds to the mean of the EEG signal. Each line represents the group average of the EEG signals of the target character (three symbol groups, each symbol group has a trial EEG, and the signal of the target character is the mean of the three symbol group), and the color indicates the signal amplitude value. Similarly, (B) and (C) indicate the cases of target adjoint symbol and non-target symbol, respectively. (D) indicates the averages across all signals of (A). (E) indicates the averages across all signals of (B). (F) indicates the averages across all signals of (C).
