Specialized Brain Mechanisms for Theory of Mind & Moral Reasoning ! V.P. Specialized Brain Mechanisms for Theory of Mind & Moral Reasoning ! The Results! consistent inconsistent normal subjects 94% (1%) 72% (4%) split-brain patients 83% (3%) 31% (5%) When belief and outcome were inconsistent, normal subjects would go with the belief 72% of the time. The split brain patients would go with the belief only 31% of the time. Two of the split-brain patients were completely consequentialists. Wouldn't take belief/intention into consideration until after. Strange finding b/c they aren't going out in the world and making morally wrong decisions; one of the things we noticed was that these judgments they had to make were right after the scenario, and very quickly. Afterwards, both joe and vicky would rationalize why they made that judgment, almost like they were making an excuse for going w/ the outcome. If given enough time, they could figure out what the appropriate answer would be, but their initial response was based on the outcome. Specialized Brain Mechanisms for Theory of Mind & Moral Reasoning ! The interpreter at work as well in the left hemisphere:! After hearing a scenario in which the waitress knowingly serves sesame seeds to somebody she believes is highly allergic to them, yet the outcome was positive because the person turned out not to be allergic, J.W. judged the action to be permissible. ! However, moments later he appeared to rationalize his response by suggesting that the “sesame seeds are just little, tiny things - not going to hurt a lot.”! What they think is happening, is the right TPJ is a specialized mechanism for belief attributions, that something that happens very quickly. A sort of initial estimation -what is the intention of this person -- whether they are intending to do harm or not. Could be very useful for social interactions. There is a 2nd process that is slower, more deliberate, when you think things through. It is this 2nd process that is probably more intact in the left hemisphere, but its this initial judgment that they are thrown off. Specialized Brain Mechanisms for Theory of Mind & Moral Reasoning ! The interpreter at work as well in the left hemisphere:! Maggie is a new employee at a small sky diving company. Her first customer weighs 200 pounds. She has just opened a new batch of parachutes.! The parachutes are faulty and should be discarded immediately. They won’t be able to support anyone heavier than 100 pounds. ! Maggie gives the 200 pound customer a new parachute. He uses the new parachute, and it cannot hold his weight. He hits the ground way too fast and dies. ! Before she gave out the new parachute, Maggie had received assurances from her supervisor. So Maggie believed that the new parachutes were well-made and could bring all her customers to a safe landing.! Giving her customer a new parachute was: permissible or forbidden?! The the outcome was negative (O-), but the agent’s belief and intention was positive (B+).! Vicky said it was morally forbidden, even though Maggie had no intention of hurting anyone at all.
