Monkeys surprise us

Humans are the most intelligent animals on Earth. 1.But sometimes, our way of thinking can become an obstacle (障碍).

Julia Watzek, a graduate student in psychology at Georgia State University, US, recently did some research on the problem-solving abilities of both monkeys and humans.2.They intended to test their ability to change their strategies(策略) in the game. In this game, each player was shown four squares on a computer screen: one striped square, one spotted square and two blank squares. While being trained to play the game, they learned that clicking the stripedsquare and then the spotted square would cause a blue triangle to pop up in one of the blank squares. Clicking on the blue triangle would give them a reward. 3. But partway through the game, the researchers introduced a shortcut (捷径). Suddenly, the blue triangle started appearing at the start of gameplay, alongside the striped and spotted squares.4.Remarkably, about 70 percent of the monkeys figured out this shortcut immediately. 5. Only 1 out of 56 human players figured out the shortcut right away.

Watzek’s conclusion was that humans tend to get “stuck in their ways” when it comes to strategic thinking. Things such as standardized testing and formal schooling might cause humans to use the same strategy over and over, even when it doesn’t work very well.

A.Monkeys never did better than human.

B.She and her team had them play a simple game.

C.The spotted square didn’t appear at all till the end.

D.Humans, on the other hand, were slow to figure it out.

E.We have mental abilities that other animals don’t have.

F.If a player clicked on the blue triangle, they’d receive their reward right away.

G.Human players would hear a “woop!” sound and monkey players would receive a snack.
