Dissociating training from practice effects. Our cross-over design allowed us to dissociate training effects from practice effects, within-subjects, by aggregating across the two 5-week blocks of training (T1-T0 and T2-T1). A–P refers to the group receiving adaptive training after baseline testing, followed by placebo training, whereas P–A refers to placebo training followed by adaptive training. Note that this is a hypothetical outcome.
