A Cephalopod Has Passed a Cognitive Test Designed For Human Children
Cephalopods are so cool.
The marshmallow test, or Stanford marshmallow experiment, is pretty straightforward. 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.
