視覺把戲，年齡不同看到的就會不同
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》是世上最穩爲人所知的視覺騙術之一。
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.
你看到的圖像取決於對面部的判斷：你要麼看見一個轉着頭的年輕女性，要不就是一個面朝左邊的嚴肅老婦。
Here's a hint: The young woman's necklace is the old woman's mouth.
這裏有個機關：這個年輕女性的項鍊就是這個老婦的嘴巴。
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.
看明白了麼？這個年輕女子的下巴就是這個老婦的鼻子，而這個老婦的下巴就是這個年輕女子的胸。
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.
那麼第一次看這幅畫你看到的到底是哪個女人其實和你的年齡有關，這是由兩位澳大利亞的心理學家做研究得出的結論。
According to the study, a younger person will see the younger woman first, while older people will see the older woman first.
根據研究結果，年輕的人更容易看到年輕女子，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位被調查者（242位男性和141位女性）年齡區間從18歲到68歲，其中中間年齡爲32歲。
They were shown the image for half a second, and then were asked the gender and age of the person that they saw.
給每人看圖半秒鐘，然後問不同年齡的被訪者看到了什麼。
While most participants saw the younger woman first, it could be because many of the participants were on the younger side.
大部分的被調查者都說自己第一眼看到了年輕女子，很可能是因爲大部分的被訪者都很年輕。
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.
當研究人員選10%年齡最大的被訪者，和10%最年輕受訪者進行調查時發現，年紀大的人先看見了老婦，而年輕人則看見了女子。
The point of the study was to determine if "own-age biases affect the initial interpretation of an image at a subconscious level".
研究結果表明“在潛意識中自己的年齡偏見對一個事物的認知產生影響。”
But even if you see the older lady first, just remember: You're as young as you feel.
不過即使你看到的第一眼時個老婦，只要記住：“你就是自己感覺到的這麼年輕。”
