Figure 1.
The left panel reflects the mirror side of the display with the motorized left hand. The right panel depicts the unseen static left arm (behind the mirror) on which participants exerted either pull/push effort or no effort.
Figure 2.
Occurrence of visually-induced kinesthetic illusion: Percentage of illusion occurrence with the passive displacement of the left arm in condition of mirror-flexion / mirror-extension in the three effort conditions (pull, rest and push).
Asterisks indicate significance (* = p<.05, ** = p<.01).
Figure 3.
Illusion intensity: Ratings in condition of Mirror-flexion / Mirror-extension and static left arm in the three Effort conditions.
Illusions were quoted as positive when the felt displacement was in the direction of a flexion and negative when the felt displacement was in the direction of an extension. Errors bars are interval confidence.

Errors bars are interval confidence.
