Mu Suppression differences (from pre- to post-manipulation) between conditions (fair and unfair) and type of movement (goal-relevant and purely kinematic). This figure depicts the change in mu suppression from pre-manipulation to post-manipulation between conditions and across movement types. The error bars display the 95% confidence intervals. A score of zero indicates no change from pre- to post-scores, and negative values indicate a loss of mu suppression from pre to post. In the fair condition, there was no difference between pre-manipulation and post-manipulation mu suppression to either observed goal-relevant-relevant or purely kinematic movements. On the other hand in the unfair condition, participants had significantly reduced mu suppression to purely kinematic movements but no differences in mu suppression to goal-relevant movements.
