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.
