Healthy human beings cant tickle themselves. This is because they ant

Healthy human beings can’t tickle themselves. This is because they anticipate the sensation and reduce their touch perception accordingly. Reducing the perception of completely predictable sensations allows the brain to focus on crucial changes in the environment not produced by the person’s own actions. A person who tries to tickle himself and is simultaneously tickled by another person will have a heightened sense of the other person’s touch compared to his own. Healthy people also can’t mistake their own voice as coming from another person. Schizophrenics, however, may hear their own voices and, having not anticipated the sounds, not recognize the voice as their own.
