Cephalopods such as octopuses, cuttlefish, etc. often display impressive behaviors, such as Squidward, who was able to predict the winning team of the World Cup, or his body color changes according to the environment. Pauline Billard, a neuroscientist at the University of Cambridge in the UK and the University of Caen in France, conducted a new study on cuttlefish: cuttlefish eat less at lunch because they have good food for dinner. Marshmallow experiment: Wait and get better rewards

In the first phase of this study, they first observed what food 29 squids like to eat the most. The research team fed squids, crabs and shrimps at the same time for 5 consecutive days and found that these 29 Squids especially like to eat shrimps, so the team divided the squids into two groups in the second stage. The two groups were given crabs for lunch, but one group was given shrimps for dinner, while the other group was given random food. The group of squid who were fed shrimp on a regular basis knew that their favorite shrimp would be their favorite at dinner. In the following 16 experiments, it was found that this group of squid ate less and less during lunch, and ate a very large amount of shrimp at dinner time. There was no difference in the food intake of this random group on the following days of the experiment. Then the eating patterns of the two groups of squid were exchanged, and it was found that the squid in the random group also ate shrimps for dinner and less crabs at noon.

The "Marshmallow Experiment" was an experiment conducted at Stanford University in 1970. Children aged 3 to 5 were given a marshmallow and told that if they did not eat it for 15 minutes, they would get another marshmallow. Sugar, experimental results show that only about 1/3 of children can tolerate this for 15 minutes. In January 2020, the University of Cambridge in the UK conducted a similar study: the crow’s marshmallow test, and the results were similar to the children’s marshmallow test.

▲The squid itself is also delicious.
