Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry. Interestingly, although the scientists believe humans show their emotions on their entire face, the dogs were not provided with the entire one. Some dogs were shown only upper halves while the others observed lower halves. After some training like how to recognise small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions. 刷阅读理解 2 They also found those being trained to read angry expressions took a longer time to learn. They guessed it may be because dogs found angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realised they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer “game” that scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touch-screen models were all females, this confirmed what had been observed in previous studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner. 刷阅读理解
