你能看到这些错觉吗?

Can You See These Optical Illusions?

早在19世纪中期
Back in the mid 1800s,
美国心理学家约瑟夫·杰斯特罗
American psychologist Joseph Jastrow
就画过这种动物
illustrated this animal.
有人会看到一只鸭子 有人会看到一只兔子
Some of you will see a duck, others a rabbit –
但不会一次就看出两个
but not both at once.
图像本身允许两种解释
The image itself allows for both interpretations
在它们之间转换需要一些脑力劳动
and switching between them involves some mental effort.
举个例子 当你在看这只鸭子的时候
And when you look at the duck, for example,
你看到的鸭子和我看到的一样么
do you see the same duck that I see?
当我们同时看这两个橙色
When you and me both see the colour orange,
两个橙色是相同的色调么
do we experience the same hue?
还是同样的幻觉
Or the same illusion?
研究表明我们主观经验的差异
Research suggests the differences in our subjective experiences
和我们脑中
are tied to the different sizes
某区域的不同大小有关
of certain areas in our brain.
在一项研究中 研究人员让参与者判断
In one study, researchers asked participants to judge
其中哪个圆圈更大
which of these circles is larger.
即使你知道这两个圆圈一样大
Even though you know these two circles are the same size,
你也很难在视觉上感受到相同大小
it’s almost impossible to see it that way.
他们利用FMRI绘制了参与者的视皮质
Using FMRI, they mapped the participants’visual cortex,
大脑中负责
the part of your brain responsible
处理视觉信息的部分
for processing visual information.
他们发现视皮质较大的人
They found those with a larger visual cortex were better
更善于判断内圈的真实大小
at judging the true size of the inner circle,
而那些视皮质较小的人最不准确
and those with a smaller visual cortex were the least accurate.
他们用其他错觉图片也得出了同样的结论
And they came to the same conclusion using other illusions.
很难解释为什么仅仅一个大脑区域的大小
It’s difficult to say why exactly the size
会导致人们更容易
of one brain area leads to people being more
被视觉错觉所欺骗
easily tricked by optical illusions.
这可能关系到
It could have to do with the concentration
视皮质内化学信使的集中
of chemical messengers inside the visual cortex.
其他研究发现 视错觉的程度
Other studies have found that the magnitude
在人们患有自闭症
of optical illusions differs in people with
或来自不同文化背景时存在差异
autism or in people from different cultures.
我们看到的东西可以用很多不同的方式构造
Things we see can be constructed in many different ways.
当孩子们在复活节(兔子季节)看到鸭兔错觉时
When children were shown the duck-rabbit illusion on Easter Sunday (rabbit season),
更多的孩子看到的是兔子
more children see the rabbit,
但在其他周日
where on other Sundays
他们更有可能看到鸭子(鸭子季节)
they are more likely to see the duck (duck season).
在十一月下旬 你甚至可以
In late November, you might even view the duck
透过火鸡节的镜头看到鸭子
through the lens of turkey season.
你看到的常是你脑中已有的图像
Sure, What You See Is What You Get,
但是请记住 事物可以通过不同的镜头来感知
but remember that things may be perceived through different lenses.
就像这些圆的大小
Like the size of these circles,
这些线条的长度
the length of these lines,
或者是一群在戏水的海豚
or a pod of dolphins splashing the hours away.
