Sources of power at the auditory tagged signal at 58 Hz and the visually tagged signals at 65 Hz and 63 Hz. A, Power change in percentage when comparing power values in the stimulus window to a poststimulus baseline for the different tagging frequencies, pooled over conditions. Power change is the largest over temporal regions for the auditory tagging frequency and largest over occipital regions for the visually tagged signals. B, Power change values in percentage extracted from the ROIs. Raincloud plots reveal raw data, density, and boxplots for power change in different conditions. CM, clear speech with a matching gesture; CMM, clear speech with a mismatching gesture; DM, degraded speech with a matching gesture; DMM, degraded speech with a mismatching gesture.
