Figure 2. TOJ task performance in Experiment 1.

Proportion of correct hand assignment across movement conditions (uncrossed-uncrossed, uncrossed-crossed, crossed-uncrossed, crossed-crossed) in the four phases of the bimanual movement (before movement, during start posture, during end posture, after movement). For conditions without a postural change (i.e., uncrossed-uncrossed, crossed-crossed), trials were assigned as ‘during start posture’ if the first stimulus occurred during the first temporal half of the movement and they were assigned as ‘during end posture’ if the first stimulus occurred during the second temporal half of the movement. For conditions with a postural change (i.e., uncrossed-crossed, crossed-uncrossed), trials were assigned as ‘during start posture’ if the first stimulus occurred before the postural change and as ‘during end posture’ if the first stimulus occurred after the postural change. Error bars denote 2 s.e. from the mean; asymmetry is due to nonlinear conversion from the GLMM’s logit scale to percentage correct. Large symbols are group means, small symbols are individual participants’ performance.
