Experimental apparatus to assess bimanual coordination. (A) Custom‐made bimanual visuomotor task. Participants rotate two dials to track a target dot (hands are covered to prevent their vision). (B) We included five frequency ratios [1:1 (isofrequency, ISO), 1:2, 1:3, 2:1, and 3:1 (non‐isofrequency, N‐ISO)], and four coordination patterns: two with the left and right dials moving in the same direction (clockwise, CW; counterclockwise, CCW), and two with the left and right dial moving toward (inwards, IN) or away from each other (outwards, OUT) [Color figure can be viewed in the online issue, which is available at http://wileyonlinelibrary.com.]
