Table 5. Means and standard deviations of P2 mean amplitudes (µV) in the time window of 154–190 ms at electrode FZ in Experiment 2 for the word structure and word tone judgment tasks when fearful, neutral and happy faces were unattended respectively.
| P2 amplitudes | Fearful(Mean & SD) | Neutral(Mean & SD) | Happy(Mean & SD) |
| Task of WS | 6.713(0.772) | 6.001(0.738) | 5.995(0.764) |
| Task of WT | 6.394(0.861) | 6.199(0.821) | 4.427(0.742) |
Note: WS refers to word structure judgment task and WT refers to word tone judgment task.
