Optimizing action separation and integration through moderate practice.

ABSTRACT: Coordinating multiple actions simultaneously often results in performance costs. However, sometimes dual actions can also be easier to perform than single actions, in particular when inhibitory control is needed during single-action control. For example, an erroneous co-execution of another response or slower single- (vs. dual-) action execution may be observed. In two experiments with different extents of practice (six blocks in Experiment 1, 12 blocks in Experiment 2), we looked into two potential practice-related sources of such effects: increased action coupling with time-on-task versus initial crosstalk followed by improved separation of action representations. Participants executed single left/right saccadic eye movements, uttered single "left"/ "right" directional words, or performe
