Why do we get tickled when somebody tickles us and we don't when we tickle ourselves?

Question

Why do we get tickled when somebody tickles us and we don't when we tickle ourselves?

Answer 1

When we tickle ourselves, our mind knows in advance that is supposed to happen. So we develop some sort of a defence to counter the effect of the tickle.

When somebody else tickles us suddenly our body is not prepared for that change of state.



Even if u hit urself (not too hard) it pains lesser than when some body else hits u suddenly.
