Touch is fundamental to how we perceive our own bodies and connect with others. A gentle brush stroke on our body can feel soothing, while a pinch or cut can be painful. We often think of touch as something we feel through our skin, but our eyes also play an important role in shaping what we experience.
One famous example is the rubber hand illusion. When people see a rubber hand being stroked while their own hidden hand is touched in the same way, they can start to feel as if the rubber hand is part of their body. This illusion shows how what we see can change what we feel.
