Can someone please help me find a talk

I think it may be a few years old now but I'm looking for TED talk in which a man explains that there is a difference between how you feel the sensation of touch when you touch something and when something else touches you.

He goes on to suggest that the difference exists because the brain predicts the sensation of touch when you deliberately touch something and subtracts the difference between the prediction and the actual sensation.

He gives an anecdote about how children in the back of a car will get into an escalating hitting war because the perceive the hit they give to be less impactful than one they receive of equal force.

I think he also gives some suggestions about why the brain makes this subtraction (to find problems with it's prediction model and to learn something about the thing with which you are interacting) but I'm not sure about this part, I may have just imagined this bit...

I hope that is enough information and I hope someone knows the talk that I am referring to. I doubt I can remember any more details than that.

      Jun 15 2012: I searched for Emily McManus and I found two pages of conversations started by her but I didn't find anything which looked like it would be particularly helpful.

      There was one which asked for your favorite single sentence from a TED talk and it's possible that the talk I'm looking for is in that thread I guess but it's a long shot and probably not worth hours of searching through pages of responses.

      Are you suggesting that I should send a message to Emily asking for assistance?

      I appreciate your suggestion but you're going to have to make the purpose of your instruction more clear.

          Jun 15 2012: Ok, I've found the conversation you're referring to.

          It's odd that it did not come up in the search results for Emily's name.

          I will post my request there, thank you for the suggestion.

          To any admin reading this conversation, my apologies for creating this redundant conversation thread.
