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.
你是否曾经尝试让一个婴儿微笑？在你打算放弃的时候，突然一下他就笑了。那是一种难以捉摸的看似充满欢乐的微笑。而事实上，那些微笑并非自发，而是充满“计谋”的。
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. [Paul Ruvolo, Daniel Messinger, Javier Movellan, Infants Time Their Smiles to Make Their Moms Smile]
研究者们发现婴儿微笑是有其原因的。当他们需要互动中的任何人（通常是父母）对他们回以微笑时他们就会对你微笑，这里笑一下，那里笑一下，具体时间都是由宝宝自己决定的。研究者们称之为“精明的”计时。这项研究结果发表在PLos ONE期刊上。[Paul Ruvolo, Daniel Messinger, Javier Movellan, Infants Time Their Smiles to Make Their Moms Smile]
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.
研究者们招募了母亲和婴儿进行测试，量化了他们之间的互动，并将其分为四个类别。第一种是婴儿希望最大化对母亲微笑的时间；第二种是婴儿想要最大化母亲对其微笑的时间；第三类是婴儿希望体验同时微笑；第四类不包含任何微笑。
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.
通过研究婴儿们何时微笑及其后续效应，研究者们能够清楚的推断出母亲70%的时间是为了体验同时微笑，而对于婴儿来说，80%的时间他们只是希望母亲对他们微笑。也就是说，母亲期待互动而婴儿只想被微笑对待。
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.
因此，你的孩子也许还不能自己吃饭、说话甚至翻身，但是在微笑时，婴儿们就能准确的知道自己在做什么。
