a, b, c Topographical plot of the scalp EEG channels for mean percent change in alpha power (8–13 Hz) from block 1 to block 2 for each of the three groups. d Mean percent change (95% confidence interval) of occipital alpha power among the three experimental groups. Control group (CON) in dark grey, external group (EXT) in orange, and internal group (INT) in teal. *Post-hoc tests reveal a significant difference (p < 0.05) between EXT vs. CON and INT vs. CON. Error bars are in 95% confidence interval. e, f, g Absolute power frequency for each of the groups at block 1 and 2. Dashed lines represent mean power at block 1. Solid lines represent mean power at block 2. The shaded area represents 95% confidence interval, with light grey representing block 1’s 95% confidence interval for each group
