Monkey and Man Salad Season 2

Facts have proved that monkeys can also understand and use money.

In fact, it is not difficult to teach monkeys to use money. In one experiment, researchers drilled a hole in a small silver plate with a diameter of 1 inch to make it look like money. First, let the monkey know that coins are valuable. When researchers give a monkey a coin, the food will be displayed. As long as the monkey threw the coin to them, the monkey would get food. A few months later, the monkey learned that coins can be used to buy food. Experiments have proved that monkeys have strong preferences for different foods. For example, one person sells jelly and the other sells apple slices. At this time, monkeys will send coins to different researchers according to their own preferences, and then get "delicious". In another experiment, monkeys even learned to recognize "coins" of different denominations. It should be clear that exchanging coins for food is not just a monkey's trick of blindly "performing one action and getting a bonus". Studies have found that monkeys respond rationally to price fluctuations. When the price of a certain food rises, monkeys will buy less; When prices fall, they buy more. The most basic laws in economics are not only applicable to humans, but also effective for monkeys. One day, the most chaotic scene happened in the laboratory: a monk hat monkey ran into the laboratory quickly, but it did not pick up the coins on the tray to buy food; Instead, it threw the whole coin back into their public living area, then fled the laboratory and rushed into the public living area to find the coin, just like "bank robbery". There were 12 more coins in the public living area, and seven monkeys kept grabbing. The researchers tried to get the coins back, but the monkeys refused to pay and made a gesture of fighting. They realized that the coins were valuable. They didn't hand over some coins until the researchers gave them food.
