6. You disgust me

6.你恶心到我了

Just as my pupils increase in size when I'm interested or turned on, so they constrict when I'm disgusted.

瞳孔散大表示兴趣，缩小则意味着厌恶。

Hess (1972) showed people pictures of injured children. First people's pupils dilated because of the shock and then they constricted to try and avoid the troubling images.

Hess在1972年的实验中给受试者观看受伤的孩童照片。人们的瞳孔起初因震惊而变大，很快又开始缩小，以避免观看这类令人难受的图片。

7. Whether I'm liberal or conservative

7.能反映出你是自由派还是保守派

Should you happen to be carrying around pictures of politicians you might be able to work out whether I'm a liberal or a conservative just from my pupil size.

如果你拿着政客们的照片晃来晃去，那么只需直视我的眼睛，就能发现我是个自由派，还是保守派。

Barlow (1969) showed people pictures of Lyndon Johnson, George Wallace and Martin Luther King, Jr.. The liberals' pupils dilated when they saw fellow liberals Johnson and King but constricted when they saw conservative Wallace. Conservatives showed the opposite pattern.

Barlow1969 年的实验里给受试者们观看了Lyndon Johnson, George Wallace 和Martin Luther King, Jr.的照片，自由派的受试者们一看到Johnson和King的照片，瞳孔立即变大了；而见到Wallace则变小，因为他是保守派的。同样，保守派的 受试者们也出现了相符的反应。

[en]8. I'm in pain[/en]

8.我感到疼痛

If you've had enough of this article now and want to cause me some pain in return, then why not stab me with a pencil? If you're watching closely you'll see my pupils dilate.

是不是已经开始嫌我太絮絮叨叨了，恨不得朝我捅根铅笔？如果您真这么做了，便会发现——我的瞳孔，扩大了。

Chapman et al. fired small electric shocks into people's fingertips and measured how much their pupils dilated. At maximum intensity the pupils dilated by about 0.2mm.

Chapman等人在受试者的指尖进行微小的电刺激，并测量瞳孔变化。当实验电刺激达到顶峰时，瞳孔可以扩大0.2mm。

But that was only to a relatively tame current. Imagine what you could do to my pupils if you plugged me into the mains.

不过那个实验带来的疼痛值只能说明瞳孔对微弱痛感的反应。要是你真捅我一下子，瞳孔估计得大过葡萄了。（喂，你的眼睛有这么大吗？）

9. I'm on drugs

9.我嗑药了...

And you can narrow down the type by looking at my pupils.

你甚至都能通过瞳孔判断出我嗑的是哪类药。

Some drugs, like alcohol and opioids cause the pupils to constrict. Others, like amphetamine, cocaine, LSD and mescaline cause them to dilate.

酒精和鸦片有缩瞳作用，其他的，比如安非他明、可卡因、LSD以及墨斯卡灵，都有扩瞳的作用。

Police officers know this and some use it as one way of checking if someone is off their face. They generally look for pupils constricted to either less than 3mm or dilated to more than 6.5mm.

警察们深知这一点。他们会检查嗑药者的瞳孔，通常小于3mm或大于6.5mm的瞳孔都是有嫌疑的。

10. My personality

10.我的性格

This one is not strictly related to pupil dilation, but it's too good to leave out.

虽然这条跟瞳孔没什么实质关系，但我舍不得把它给略掉。

If you look closely at the coloured part of my eye, the iris, you might even get some clues as to my personality.

因为，如果你近距离地凝视我眼中的着色部分，即虹膜——你甚至能获知一些我性格的秘密。
