Stress double-dissociated earlier from later task-evoked GFP (SD μV). Threat amplified the N1 (184–236 ms) and attenuated the P3 (316–488 ms), without substantially altering the P1 (112–144 ms). Confidence bars indicate the probability of the null hypothesis being rejected by chance; non-overlapping bars indicate p < 0.05 (Shackman et al., 2010).
