Why Are Babies So Cute
为什么婴儿如此可爱
There's no denying that human babies are cute,but even other species tend to have adorable infants.
谁都不能否认婴儿非常可爱，但是其他物种的幼崽也非常可爱。
So why has science conditioned us to find babies so precious?
那么，从科学的角度讲，我们为什么觉得婴儿如此可爱呢？
Is there something specific that triggers are urged to hold and squeeze them?
有没有什么特别的按钮触发我们这种感觉呢？
Interestingly studies have found that the CATmonkeys pay little attention to new one faces leading researchers to believe that the cute feeling may be an entirely human trait.
有趣的是，科学家发现，猴子不会注意到新的面孔，因此研究人员相信，可爱的感觉完全是人类的特征。
Unlike many other species,once born,human babies are completely dependent on their parents for survival.
跟其他物种不同，一旦出生，人类的婴儿完全依靠父母来存活。
As a result humans have adapted to find certain traits aesthetically pleasing and downright adorable in an effort to increase interaction,care and protection from parents.
因此，为了沟通，照顾和得到父母保护，从审美的角度讲，人们习惯于发现令人快乐和喜爱的特点。
This in turn enhances aspin survival and perpetuates our species.
反过来，这让我们人类作为一个物种不断繁衍，生生不息。
But what exactly makes something seem cute?
但是，让婴儿看上去可爱的特点有哪些呢？
Known as baby schema,scientists have come up with a set of tests traits that make something appear cute.
科学家提出了一套实验，称为婴儿模式，对一些看上去可爱的特征进行测试。
These include a large rounded head relative to the body,large eyes below the midline at the face,protruding cheeks,a big forehead,round body and soft surfaces.
其中包括比例恰当的圆圆的脸，大大的眼睛，突出的脸颊，宽阔的额头，圆润的身体和柔嫩的皮肤。
Ah...and no doubt our species are born with fully grown large eyes,almost full-size brains,soft skin,big cheeks and round bodies.
毫无疑问，我们的物种天生就有着大大的眼睛，发育饱满的大脑，柔软的皮肤，大大的脸颊和圆润的身体。
In fact in test for baby photos are manipulated to have more BB schema traits whether they're human babies or dogs and cats for example,they're rated as cuter and participants felt a stronger motivation to take care of these babies.
实际上，在婴儿照片测试中，拥有更多婴儿模式中的特点的照片更容易被评为可爱，参加者更有动力照料这些婴儿，无论这些是人类的婴儿还是狗和猫的幼崽。
Even when the front of cars were altered in accordance to the baby schema like making the headlight become larger to mimic big guys,participants experienced a more positive response.
即使是汽车根据婴儿模式进行改造，比如把车灯扩大，模仿婴儿的面孔，参与者也容易给出更积极的反应。
It turns out it's all in our head when viewing babies with enhanced baby skin,the proportions,the critical index in our brain is activated.
事实表明，在我们的大脑中，当我们看到相应的婴儿的特征时，大脑中的关键指数就会被激活。
These parts of the brain enhance the anticipation of a reward and can lead to a sentiment joining motivation to care for something and the urge to cuddle or hug an object.
大脑的这些部分会增强对回报的预期，导致照料某物的动机，拥抱一个物体的冲动。
