• Rats from same litter in test cage -> electric shocks through cage floor

• Rats rearing up on their hind legs and pushing each other

• If shocks very intense & long enough -> rats biting each other

• -> Powerful & universal animal instinct to attack when hurt

• Some "teachers" hand in cold water, others in warm water

• Cold water -> significantly more likely to be punitive towards partners
