In a modified version of the Stanford marshmallow experiment (in which children were told they would receive a second marshmallow if they could avoid eating a first for a certain period of time), researchers at the Marine Biological Laboratory at the University of Chicago have determined that cuttlefish can pass delayed gratification tests. This puts them in the ranks of humans and other primates, dogs, and some birds. Of course the experiment’s design seems flawed to me because they used a piece of far less desirable raw shrimp as the instant gratification reward, and a much more appetizing live shrimp as the delayed gratification reward. What cuttlefish wouldn’t be more attracted to a dinner that’s still moving? This isn’t hibachi, the chef isn’t about to flip a piece of shrimp into my mom’s hair. Also, just for the record, I have zero tolerance for delayed gratification. I will eat that first marshmallow as soon as you set it down and fight you for the second while I’m chewing.
