Okay, that didn't look all that convincing. But I'm sure it's different when you're wearing the suit yourself. And in fact, participants did claim to feel personal ownership of their virtual bodies. This was equally true whether that virtual body was that of a child or a tiny adult. However, they overestimated the size of objects (as indicated by holding their hands apart a corresponding distance) more when embodying children’s bodies than when their virtual bodies were small adults. Remember both bodies were the same size, they just had different proportions.
