Relationships between individual differences in pleasantness score and areal differences of occupancy rate in the respective frequency band. A 4–8 Hz, B 8–12 Hz, C 12–16 Hz and D 16–23 Hz. Each data point represents the differences in the pleasantness score and the areal differences in the occupancy rate. These two-dimensional graphs are the same as those of the X–Y planes, as shown in Fig. 4. Data from all participants are plotted together. The black line shows a linear fit. The red regression line with asterisks denotes that the areal differences in occupancy rates correlate with differences in pleasantness scores. n = 13, A: R2 = 0.305, F = 6.267, P = 0.029; B: R2 = 0.344, F = 7.29, P = 0.021; C: R2 = 0.474, F = 11.82, P = 0.006; D: R2 = 0.196, F = 3.92, P = 0.073
