To test the idea, the researchers had schizophrenics play tit-for-tat against themselves. Schizophrenics have trouble recognizing their own actions—that is, they often attribute their behavior to an alien source. Some can even tickle themselves. If our brains discount the feeling of our own actions to help us differentiate between self-generated and externally generated sensations, then a group of subjects who can’t make this distinction might simply be missing this sensory reduction. In that case, reasoned Wolpert and his team, schizophrenics should be better at playing tit-for-tat by the rules. And they were. When the robot pushed on the fingers of schizophrenics they were much better at pushing back on themselves with the same amount of force the robot had applied. Their brains didn’t discount the consequences of their own actions as much as the brains of healthy subjects did.

I can't tickle myself, but if I jab a fork into my own leg it still hurts. What does that mean?
