FIGURE 4.

Right hemisphere beta-oscillations as correlates of likeability (all four conditions). (A) Result for regression analysis using mass-univariate regression analysis with the pleasantness ratings as the predictor variable on each time-frequency-channel data point. The thresholded t-statistic (adjusted for multiple comparisons) reports the significance of the regression analysis for all time-frequency bins. The highlighted time-frequency window survived the multiple comparisons. (B) Topographic representation (thresholded) of the t-statistic for the regression analysis in the significant cluster (A). (C) Scatterplot of induced beta-oscillations in right temporo-parietal electrodes (see A) against likeability ratings of each fabric (in different colors). The mean across conditions was subtracted from each subject (both EEG and ratings) to reveal differences between conditions rather than inter-individual differences of their averages across conditions. There is a strong positive correlation between the beta-response and the likeability ratings, indicating that the effect shown in (A,B) does not reflect a mere physical difference in stimulation.
