The main interaction of Time, Condition, and Test was highly significant [ F (12, 456) = 19.51, p < 0.001, η 2 p = 0.34].
The main interaction of Time, Condition, and Test was highly significant [ F (12, 456) = 19.51, p < 0.001, η 2 p = 0.34].
The significant interaction for left invalid stimuli was partly explained by a strong trend of the single active condition leading to a larger improvement than the single sham condition [ F (1, 40) = 4.00, p = 0.052, η 2 p = 0.09], but was mainly explained by a significantly larger improvement after repeated combined treatment as compared to cognitive training alone [ F (1, 40) = 21.12, p < 0.001, η 2 p = 0.35].
