Figure 2. The waveforms (A), scalp topographic distribution (B), and bar charts (C) of the negative attention bias indices (* p < 0.05, *** p < 0.001). The shaded areas were the time windows of 180~500 ms, 500~1000 ms, and 1000~2000 ms. Note. HSA: high social anxiety group, LSA: low social anxiety group, WM: working memory.
