As part of scientific work, scientists decided to conduct a children’s Stanford “marshmallow” experiment, but on cuttlefish. Recall that the research is being conducted to find out if children are able to postpone pleasure for the double benefit. Within its framework, the child was seated in front of the sweets, while being informed that if he could hold out for 14 minutes and did not eat them, his portion would be doubled. In the course of this work, it was found that children are indeed able to hold out for the double benefit.

The same study was carried out on cuttlefish, only shrimp meat was used instead of sweets. So, about six cuttlefish were placed in a container with water, in which there were two chambers. One of them contained king prawns, which are not favorites of cuttlefish, while the other contained herbal shrimps more loved by them. On the doors, in turn, there were special signs, which the cuttlefish were taught to recognize in advance. For example, a triangle meant that the door would open only after 130 seconds, while a square meant a closed door, and a circle meant an instant opening. The cuttlefish were able to wait for the double benefit, as did the children.
