Table 1 Correlation between TRF features and behavioral data. The maximum and minimum amplitude of components and the latency of them found for each subject. Then, correlations and p-values between TRF features and the subject’s post-test score and NASA-TLX index were calculated and reported. The results show that there is a relation between behavioral data and TRF features.
