how come we dont laugh when we tickle ourselves??

Answer 1

Brain scientists at the University College London have pinpointed the cerebellum as the part of the brain that prevents us from self-tickling. The cerebellum is the region located at the base of the brain that monitors our movements. It can distinguish expected sensations from unexpected sensations. An expected sensation would be the amount of pressure your fingers apply to your keyboard while typing. An unexpected sensation would be someone sneaking up behind you and tapping you on the shoulder. While the brain discards the sensation of typing, it pays a lot of attention to someone tapping on your shoulder. The difference in reactions from expected to unexpected is a built-in response that probably developed in early human history to detect predators.

Answer 2

Because of the feedback though our fingers and hands. Same as it not feeling as good when w@nking instead of... well not wanting to be rude, just trying to come up with a good example.
Point is, the brain isn't fooled. That's where sensation of pleasure, pain, and tickling is felt anyway.

Answer 3

On a cellular level the hand that tickles is the same DNA as what body part is being tickled. You have a word for the act, but to the body its no different than a rub-skin on skin.
When you sneeze, if alone do you wish yourself "God bless me"?
When you burp or pass gas alone do you ask yourself to excuse yourself?
The blob of protoplasm we are is one complete unit.
The few exceptions usually involve an imaginary or visual distraction, or a great amount of will.

Answer 4

I have no clue, but I don't really agree with the idea that it is because we know it's coming. I could ASK my boyfriend to tickle me, and I would still laugh. I obviously know that it is coming.

I don't laugh out loud when I tickle myself, but if I try to tickle my own feet, they jerk away from me.

Answer 5

Basically what everyone else said: because you are expecting it. Some really ticklish spots might give you the feeling, but i doubt you will laugh as hard as when someone else does it. Have you ever seen really ticklish people laugh before they even get touched. I've seen it and it shows that expecting to laugh will make you laugh.

Answer 6

We are expecting the tickling sensation, right? Our mind knows how much we tickle ourselves and even th minutest detail of our action. So it doesn't feel like laughing. And it even knows that it is our own hand that is tickling ourselves.. I think this is the answer, dunno.... :-)

Answer 7

sorry to be the one to tell you that, that statement is not true I tickle myself a lot I'm so ticklish on my feet that it's hard for me to put on a pair of socks because if my hand or nails brush up against my feet I'm laughing and jumping around.

Answer 8

I think it is because we can control what we are going to do, which means we know if we will get tickled or not.

Answer 9

I think it's because we're expecting it, a tickle makes us laugh because we're not expecting it. Sort of like why it doesn't hurt when you pinch yourself.

Answer 10

I laugh when I tickle myself.
