A highly significant main effect of hemisphere, F (2, 52) = 14.64, p < .001, η p 2 = 0.36, was observed, with a higher voltage recorded from electrodes placed at the left (1.26 μV) and right hemispheres (1.42 μV) than from the central (0.03 μV) electrodes, ps < .05.
Notably, the Pearson correlation coefficient for the fruits with implied moving water condition between the posterior P2 and early frontocentral negativity exhibited a marginally significant negative correlation ( ρ = -0.375, p = 0.054).
In the present study, water, regardless of whether it was moving or static, significantly enhanced the perceived taste of fruit compared with fruit presented alone, whereas implied moving water also enhanced the perceived taste, but the difference did not reach statistical significance compared with fruit presented with static water.
