It turns out that pigs can also play video games
Playing a video game means instantly performing a series of actions such as 'reading the information displayed on the screen', 'determining what is happening', and 'entering appropriate actions to get a reward'. Therefore, extremely high intelligence is required. A research team at Purdue University in the United States reported that pigs were able to play video games with a joystick.

Two Yorkshire pigs named 'Hamlet' and 'Omelet' and two mini pigs named 'Ebony' and 'Ivory' were used in the experiment. A joystick was placed in front of the computer monitor so that the pigs could operate it with their noses, and in the experiment, all four pigs were trained to operate the joystick.
The game that can be played is 'a cursor that can be operated with a joystick hits a maximum of three walls displayed on the screen'. The play time was 10 minutes once a day, and it was held 5 days a week. In order to strengthen the behavior of the pig, the pig was given food as a reward when clearing the game.
Hamlet and Omelette's performance did not achieve significant performance with three walls, but outperformed chance success with one or two walls.
In addition, Ivory and Ebony performed significantly better than chance success in the case of three walls. In the case of two walls, only ivory showed significant performance, and in the case of one wall, both showed significant performance, but ivory showed higher performance.
In addition, according to the research team, communication may have had a strong impact on pig learning. For example, there were scenes where it was thought that when the machine could not distribute food well, it responded to the opponent by barking and physical contact, and when the task of the game was difficult, it communicated by barking. thing.
The researchers say that the result that 'thumbless animals used joysticks and succeeded in the job of playing games' is noteworthy. Professor Candice Croney, lead author of the treatise and director of the Center for Animal Welfare Sciences at Purdue University, said, 'Understanding the notion that one's behavior influences others is a great achievement for animals. Being able to play video games will give us some thought about what else pigs can learn and how that learning affects them. '
In addition, Professor Crony said, 'It is very important to find out how we should interact with pigs and what they do and how they affect us. To us, how pigs are. There is an ethical obligation to gain information and understand what can be learned and remembered. '
