Pre–post sham and tDCS comparisons of CBT span under interference. The CBT spans in the motor interference condition were significantly improved (p = 0.007) after tDCS treatment (span mean ± SE: 4.219 ± 0.133) relative to the pre-tDCS session (span mean ± SE: 3.594 ± 0.179) on the same day. This effect was not observed between pre- (span mean ± SE: 3.719 ± 0.169) and post-sham (span mean ± SE: 3.719 ± 0.169) performance (p = 1.000) on the sham day. The CBT spans in the interference condition were significantly increased (p = 0.023) when comparing the post-tDCS block (span mean ± SE: 4.219 ± 0.133) with the post-sham block (span mean ± SE: 3.719 ± 0.169) spans. There was no significant difference (p = 0.614) between the pre-tDCS block (span mean ± SE: 3.594 ± 0.179) and the pre-sham block (span mean ± SE: 3.719 ± 0.169). SE represents standard error. ^∗p < 0.05.
