Correlation between neural entrainment and visual perception. Scatterplot and Spearman’s correlation coefficient between (a) the 40 Hz SNR and experienced discomfort, (b) the 40 Hz SNR and the experienced flicker, and ( c) the experienced flicker and experienced discomfort for each type of stimulus. r denotes Spearman’s correlation coefficient for the aggregated data, and P is the P-value of the significance of the correlation. A significant positive correlation is found for all pairwise correlations. The scatterplots show observations from experiments A and C for each subject averaged over repetitions and EEG channels and averaged over repetitions, respectively. Linear regression models are fitted to the entire data and to each stimulus type (ISF, CF, IF) to estimate the best fit, and these lines are included in the scatterplots.
