In a nutshell
A visible artificial hand can briefly feel like one’s own when it and the hidden real hand are touched in matching ways. The strength of this sense of ownership varies greatly.
Why does it happen?
The brain combines vision, touch, and information about the position of one’s limbs. Timed matching touches on a plausibly positioned artificial hand can change this assignment. Premotor and parietal networks are involved; expectations and instructions can also affect what participants report.
Frequency
Not all participants experience the rubber-hand illusion equally strongly. Estimates depend on the setup and on how the feeling of ownership is measured.
Frequency is a qualitative description, not your individual probability.
Is it normal?
A temporary body illusion under special conditions.
