Fig. 5: Pre-stimulus beta power predicts the congruency effect on confidence ratings.
From: Pre-stimulus beta power mediates explicit and implicit perceptual biases in distinct cortical areas
Ai The congruency effect on confidence between response and stimulus probability in the stable environment (n = 43 participants): participants are more confident in no responses in the low probability condition and more confident in yes responses in the high probability condition. Bi the congruency effect on confidence between response and stimulus probability in the volatile environment (n = 39 participants): participants are more confident in no responses in the low probability condition and more confident in yes responses in the high probability condition. Aii Significant congruency effect on confidence between response and beta power in the stable environment: beta power does predict the confidence for both yes and no responses, conditional on the probability condition. Bii Significant congruency effect on confidence between response and beta power in the volatile environment for yes responses: lower beta power increases confidence in yes responses. The error bars show the 95% confidence interval. Significance levels ***p < 0.001, **p < 0.01, *p < 0.05.
