I guess I'd just call it 'learning'. Now they know about the choice they made; of course they value it over an unknown (the choice(s) not made).
The human animal is characterized by this: learning from a single example. For better and worse. Its the reason we created civilization; its the reason we believe in witchcraft and the lottery.
E.g. walk into a chimp's domain with a screwdriver, fool with the screw on an outlet cover, set the screwdriver on the floor and leave. The chimp may wander over, may pick up the screwdriver, might chew on it.
A 3-year-old human will go straight to the screwdriver and jam it into the socket.
I'm not sure anything new was shown by this experiment.
