Figure 8.
Mean Z-scores of the six channels (ch. 9, 18, 20, 22, 23, 24) selected as COI in the same-face and the different-face conditions, respectively. The vertical line in each graph represents 1 SE. All of these channels showed higher Z-scores in the different-face condition than in the same-face condition for oxy-Hb. The main effect of condition was significant with 2 (condition) × 5 (channel) ANOVA (p < 0.01).
