Researchers have published results of a new study focusing on weird-looking squid. In the study, researchers provided the first evidence of a link between self-control and intelligence in non-primate species. In the experiment, the common squid in cabinets was introduced to the foods they usually eat in separate rooms.
In one of the rooms was a piece of king shrimp that they could eat right away. In the other room there was live grass shrimp which is their favorite food. However, squid can only eat shrimp if they wait and do not eat the shrimp. Researchers Test group From the delay times starting at 10 seconds and increasing the delay by 10 seconds each time the experiment was performed.
All six squid species used in the experiment showed restraint in waiting for the grass shrimp, ignoring the king shrimp. In the test, the squid with the most restraint could wait 130 seconds to get grass shrimp, which is comparable to large-brained animals such as chimpanzees. The researchers were surprised that the squid would wait more than two minutes for a better snack.
Researcher Dr. Alexandra Schnell of the Department of Psychology at the University of Cambridge was surprised that a fast-growing animal with an average age of less than two years would be picky about food. The researchers also tested the learning ability of each sample of squid. They used a dark gray marker and a white marker placed at random locations in the tank. The cuttlefish learned to associate one color with a reward, and then the reward was switched so that it related to the other color.
The cuttlefish learned to bond faster and faster to realize that it was the switch that showed more restraint in the first task. Interestingly, the same link between better learning performance and better self-control is found in both humans and chimpanzees, but this is the first time it has appeared in non-primate species.
