Change in working memory performance from pretest to posttest (A–C) and across cognitive training visits. (D,E) Estimated marginal means (error bars = 95% confidence intervals) derived from linear mixed models testing intervention effects on performance in trained tasks (trained stimuli), in the context of hypothesis 3 (COG + PE & PE + COG vs. COG; A), hypothesis 4 (COG + PE & PE + COG vs. PE; B) and hypothesis 1 (COG + PE vs. PE + COG; C), with spaghetti lines corresponding to individual change trajectories (T-scores, M = 50, SD = 10). Model-implied regression lines illustrating the effect of training visit on progress in the n-back task during the cognitive training intervention (maximum score = 24), in the context of hypothesis 3 (COG + PE & PE + COG vs. COG; D) and 4 (COG + PE & PE + COG vs. PE; E). COG = cognitive training, PE = physical exercise, COMB = PE and COG, irrespective of order.
