Some of the most striking discoveries in psychology have come from patients with deficits of various kinds. Phineas Gage, one of the most famous patients in psychology, was thought to have suffered emotional blunting – along with personality changes – after a tamping rod was propelled through his frontal lobes. Less dramatically, but no less vitally, it seems highly probable that common psychological disorders have, at their heart, a problem processing emotions. Two examples are alexithymia and autism spectrum disorders, both of which seem to involve problems with empathising. But what is empathy?

Having now seen the excellent documentary on the autistic savant, Daniel Tammet, and noting the subject’s popularity, I’ve done a little Googling to get some more information for you…
