Rosenblum talks about the rubber hand illusion, where people start to feel like a fake rubber hand is part of their body if it's stroked at the same time as their real hidden hand. This shows how the brain mixes sight and touch to create a sense of body ownership. It's the idea that it is not just what we feel or see alone; it is both together. This idea is also included by studies like Botvinick & Cohen (1998) which show how easily our sense of self can be tricked.

This expands what we learned about multisensory perception because it shows that it also shapes our sense of self and not just how we experiences the outside world. It made me think about how this could help people using prosthetics or in virtual reality. If our brain can adopt a rubber hand, it could potentially also accept a robotic one as well. It shows how science can turn brain tricks into real-life tools!
