视觉把戏，年龄不同看到的就会不同

My Wife and My Mother-in-Law is one of the most well-known optical illusions in the world.

《我的妻子和我的岳母》是世上最稳为人所知的视觉骗术之一。

It hinges on facial perception: You can either see a young woman turning away or the profile of an older woman staring solemnly towards the left side of the drawing.

你看到的图像取决于对面部的判断：你要么看见一个转着头的年轻女性，要不就是一个面朝左边的严肃老妇。

Here's a hint: The young woman's necklace is the old woman's mouth.

这里有个机关：这个年轻女性的项链就是这个老妇的嘴巴。

See it? The young woman's chin doubles as the older woman's nose, and the old woman's chin is also the young woman's chest.

看明白了么？这个年轻女子的下巴就是这个老妇的鼻子，而这个老妇的下巴就是这个年轻女子的胸。

If you've ever wondered why you see whichever woman you see first, an Australian study conducted by two psychology professors concluded that it has to do with your age.

那么第一次看这幅画你看到的到底是哪个女人其实和你的年龄有关，这是由两位澳大利亚的心理学家做研究得出的结论。

According to the study, a younger person will see the younger woman first, while older people will see the older woman first.

根据研究结果，年轻的人更容易看到年轻女子，反之亦然。

The study included 393 participants (242 males, 141 females) from ages 18 to 68, though the median age was 32.

研究共有393位被调查者（242位男性和141位女性）年龄区间从18岁到68岁，其中中间年龄为32岁。

They were shown the image for half a second, and then were asked the gender and age of the person that they saw.

给每人看图半秒钟，然后问不同年龄的被访者看到了什么。

While most participants saw the younger woman first, it could be because many of the participants were on the younger side.

大部分的被调查者都说自己第一眼看到了年轻女子，很可能是因为大部分的被访者都很年轻。

When the researchers separated the oldest 10 percent and the youngest 10 percent of those surveyed, they found that the older set saw the older woman first, and the younger set the young woman.

当研究人员选10%年龄最大的被访者，和10%最年轻受访者进行调查时发现，年纪大的人先看见了老妇，而年轻人则看见了女子。

The point of the study was to determine if "own-age biases affect the initial interpretation of an image at a subconscious level".

研究结果表明“在潜意识中自己的年龄偏见对一个事物的认知产生影响。”

But even if you see the older lady first, just remember: You're as young as you feel.

不过即使你看到的第一眼时个老妇，只要记住：“你就是自己感觉到的这么年轻。”
