Question

Once a baby cries, the parents will go to see what happened as soon as possible. According to a new study, a baby’s cry can make adults react very quickly, even if they are not related(相关的).

Oxford University researchers used a game called Whack-a-mole for the study. The game needs people to hit one buttons(按钮). The players must react as quickly as they can to hit the button that lights up at random(随机的). It is a game that requires speed and accuracy(准确度).

The study included 40 men and women volunteers aged 19 to 59. Some of them had sons or daughters but none had a baby at the time. They played whack-a-mole after listening to different sounds, including babies’ crying, the crying of adults in trouble and birds’ song that sounds like babies’ crying.

The volunteer’ scores  were higher after listening to the sound of crying babies. Men and women had similar scores. The results showed that a crying baby gets special attention.

“Few sounds make people react quite like the cry of a baby,” said Morten Kringelbach of Oxford’s psychiatry department, who led the study.

He added that a baby’s cry can increase adults’ heart rate and blood pressure. This is understandable, because in the course of human evolution(进化), taking care of babies has always been an important job for adults. When a baby is hungry or feeling bored or unwell, it will cry. As a result, human brains and bodies develop a special reaction to a baby’s cry.
