Quizplus · Accepted Answer

The lack of ticklish sensation when tickling oneself is due to the brain's ability to predict and anticipate self-generated sensations, which can diminish the ticklish response. This is an example of how cognition (i.e. expectation and anticipation) can influence the brain's response to sensory stimuli.
