婴儿 : 蒙娜丽莎的微笑

Babies Just Want to Be Smiled at

Ever try to get a baby to smile? It can seem close to impossible - and then suddenly there it is: that elusive, seemingly joyous grin. Well it turns out those smiles aren't spontaneous - they're strategic.

Researchers have found that when babies smile, it's for a reason. They want whoever they're interacting with - typically a parent - to smile back. And they time it just so, a smile here and a smile there. The researchers call it sophisticated timing. The study is in the journal PLoS ONE.

The researchers enlisted real mothers and infants and quantified their interactions, which fell into four categories. One: babies wanted to maximize the amount of time smiling at their mothers. Two: they wanted to maximize the time the mothers smiled at them. Three: they wanted to experience simultaneous smiling, and four: no smiling at all.

By studying when smiles happened and what the subsequent effect was, the investigators were able to figure out that for mothers the goal 70 percent of the time was to be smiling simultaneously - while for babies 80 percent of the time they just wanted their mother smiling at them. So, mothers want the interaction, while babies just want to be smiled at.

So your baby may not be able to feed itself, talk or even turn over yet. But when it comes to smiles, babies seem to know exactly what they're up to.

你有没有把婴儿逗笑的经历?有时候你觉得完全不可能让它笑,但是突然它又露出一个难以捉摸的欢笑。其实这种微笑并不是发自内心的,而是婴儿的一种策略。

研究者发现婴儿微笑都是有原因的。它们把微笑当作一种互动,它朝谁笑,就是希望那个人还以微笑,特别是它的爸妈。而且它们的微笑的时间都是经过准确计划的,自己笑多久,对方笑多久。研究人员将其称为高精度时间规划。

研究人员从现实生活中找到了一些母亲和婴儿,把他们之间的微笑互动量化后,分成了以下四种:第一种,婴儿希望朝母亲微笑的时间最长;第二种,婴儿希望母亲朝它微笑的时间最长;第三种,它们希望和母亲同时微笑;第四种,完全不笑。

通过分析微笑时间和后续反应,研究者们发现:对于百分之七十的母亲而言,她们的目标都是和婴儿同时微笑。而对于百分之八十的婴儿而言,它们只是希望自己的母亲还以微笑。因此母亲需要的是互动,婴儿需要的只是别人朝它微笑。

所以,你的小宝贝可能还不会自己吃东西、说话,甚至不会翻身,但是当它笑的时候,绝对是有预谋的。
