Various Messages,Pupil used to Send Through Eyes

Sunday, 15 June 2014 0 comments

Our pupils, the black holes which let light into the eyes, don’t just help us see, they also signal what’s going on in our minds.


Communication send by pupil
Here are various pieces of psychological research which show how changes in pupil size reveal many aspects of thought.

I’m thinking hard

Look into my eyes and ask me to name the cigar-smoking founder of psychoanalysis and you won’t see much change in my pupil size. The name Sigmund Freud comes easily to my lips.

But ask me to explain the laws of cricket and watch my pupils expand.

My brain is overloaded

Keep watching my eyes closely and you’ll spot the point when explaining the laws of cricket gets too much.

Poock (1973) reported that when participants’ minds were loaded to 125% of their capacity, their pupils constricted.

I’m brain damaged

The reason doctors and paramedics flash a light in patients’ eyes is to check their brains are working normally (and because it’s such an easy test to do). They use the acronym PERRL: the Pupils should be Equal, Round and Reactive to Light.

If my brain is broken, say, because I’ve had a bump on the noggin, you won’t see PERRL. There may well be other extremely subtle clues, like the blood pouring from my head.

You’re holding my interest

The size of my pupils can also signal whether I’m interested in what you’re saying.

White and Maltzman (1977) had participants listening to excerpts from three books: one was erotic, another involved mutilation while a third was neutral.

Their pupils widened at first for all three. But they only remained wide for the passages that were erotic or involved mutilation.

I’m likely to be interested in anything new, so my pupils will dilate a bit at first, but they’ll only stay dilated if I continue to be interested.

You’re turning me on

If things take a sexual turn then our eyes are also involved. Both men and women’s pupils expand when they are sexually aroused.

However, not everyone agrees big pupils are a signal of sexual arousal. It tends to get tested by showing nude pictures to people and some argue that we’re just really interested in the nude form.
