Question

It seems that there’s a good reason why dogs have remained as man’s best friend. Scientists have found that dogs are the only animals that can read emotion in faces much like humans. The finding suggests that like an understanding friend, dogs can see at a glance if we are happy, sad, pleased or angry.

　When humans look at a new face, their eyes usually wander left, falling on the right hand side of the person’s face first. This “left gaze bias”（左视偏好） only happens when we look at faces and does not apply(应用于) any other time, such as when looking at animals or objects.

　A possible reason for the tendency（倾向） is that the right side of the human face is better at expressing emotions.

 Researchers at the University of Lincoln have now shown that pet dogs also have “left gazes bias”, but only when looking at human faces. No other animal has been known to show this behavior before.

　A team, led by Dr Kun Guo, showed 17 dogs images(形象) of human, dog and monkey faces as well as objects.

　Film of the dog’s eye and head movements shows a strong left gaze bias when the animals were presented with human faces. But this did not happen when they were shown other images, including those of dogs. “Guo suggests that over thousands of generations of association（交往） with humans, dogs may have developed the left gaze bias as a way to guess our emotions,” New Scientist magazine reported.

　“Recent studies show that the right side of our faces can express emotions more accurately than the left. If true, then it makes sense for dogs — and humans — to see the right hand side of a face first.”
