Alex Schnell is the researcher behind the experiment that proved cuttlefish can “pass” the marshmallow test (a test originally designed to test delayed gratification in humans), that has been circulating the internet in recent weeks. Alex is a comparative psychologist and a behavioral ecologist with a background in marine biology. Her research interests center on complex learning and memory mechanisms in animals and how these abilities have evolved across diverse taxa. Her primary model species include cephalopods (octopus, cuttlefish, and squid) and corvids (members of the crow family).
