Cuttlefish were given a new version of the marshmallow test, demonstrating their ability to learn and adapt. Researchers suggest this could give them an edge in their marine environment.
Back in 2021, a test of cephalopod smarts reinforced how important it is for us humans to not underestimate animal intelligence. Cuttlefish were given a new version of the marshmallow test , and the results may demonstrate that there's more going on in their strange little brains than we knew. Their ability to learn and adapt, the researchers said, could have evolved to give cuttlefish an edge in the cutthroat eat-or-be-eaten marine world they live in.
A child is placed in a room with a marshmallow. They are told if they can manage not to eat the marshmallow for 15 minutes, they'll get a second marshmallow, and be allowed to eat both. This ability to delay gratification demonstrates cognitive abilities such as future planning, and it was originally conducted to study how human cognition develops; specifically, at what age a human is smart enough to delay gratification if it means a better outcome later. Because it's so simple, it can be adjusted for animals
