Relationships between the three items of pleasantness scores, frequency occupancy rates, and eating times. Individual values of “differences in pleasantness score,” “differences in eating time,” and “differences in areal occupancy rate” are plotted together as three dimensional graphs. Four graphs are arranged according to the respective frequency band. A Theta band, B Alpha band, C Low Beta band, D Beta band. The X-axis represents “differences in areal occupancy rate,” the Y-axis represents “differences in pleasantness score,” and the Z-axis represents “differences in eating time.” The ball-like small black circles indicate the individual values. Relationships between “differences in areal occupancy rate” and “differences in pleasantness score” are projected on the X–Y plane, as small red squares. The relationships between “differences in areal occupancy rate” and “differences in eating time” are projected on the X–Z plane as small green squares. Relationships between “differences in pleasantness score” and “differences in eating time” are projected on the Y–Z plane, as small blue squares. Note the interrelated relationships between the three different comparisons plotted on the three-dimensional graph
