What is it about?

Body ownership feeling arises through the congruent and synchronic stimulation of multiple sensory channels. To explore the possible differences between the visuo-tactile and the visuo-proprioceptive channels, we decided to explore the Rubber Hand Illusion (RHI) by changing the postures of the thumb and index finger of the participants.

Why is it important?

Based on the overall measures, the RHI observed went from stronger to weaker with full congruence; visuo-proprioceptive incongruence and visuo-tactile congruence; visuo-proprioceptive congruence and visuo-tactile incongruence; full incongruence. Our results confirm that congruent visual and tactile mapping is important, though not mandatory, to induce a strong sense of ownership.

Perspectives

The idea of this protocol was born several times ago when I was a graduate student. Never give up!
