They say that the eyes are the mirror of the soul, but some might disagree; scientifically, we know that the eyes are a window to the brain, the only visible part of our nervous system. They can reveal much about us; The size of the students can tell if we are excited, upset or with other sensations.
Our eyes and especially our pupils don’t just help us see; they also indicate what’s going on in the mind.
- In this article.
- We’ll talk about a list obtained through psychological research.
- Which shows how changes in pupil size reveal many aspects of our thinking.
Research has shown that the more the brain works and is compromised, the more pupils expand.
If you have to give a simple answer, students don’t change. When an answer becomes more difficult for you, students expand. This way, you can understand whether a person has difficulty answering a certain question and, more interestingly, whether they are lying or not.
If you look closely at a person’s eyes while resolving “impossible” multiplication counts, such as 1345 x 2022, and insist on seeking the answer, their pupils react by dilation.
When people’s minds are overloaded to 125% of their ability, students expand and leave the problem unresolved or surrender.
When doctors or nurses place flashing light in patients’ eyes to see if their brain is functioning properly, the pupils of a healthy brain should be equal, round, and reactive to light. In English, this simple student test is called PERRL.
If the brain was traumatized because it had a strong heartbeat, PERRL probably won’t occur.
Student size can also indicate whether the person is interested in what they are saying.
In one survey, students heard 3 book summaries: one was erotic, the other on bloody mutilations and the third on a neutral topic.
At first, students expanded on all 3 subjects, but the dilation continued only during the book summaries on eroticism and mutilation, while in neutral they re-contracted.
Students demonstrate how sensitive the mind is to everything new at first, but pupils remain dilated if novelty does not fade.
When we are sexually aroused, the pupils of men and women expand
However, not everyone agrees that the longer the pupils are, the greater the sexual arousal. Other psychologists say the mind is really interested in nudity rather than showing real emotion.
Just as students grow up when you’re interested in something, they shrink when you’re upset.
Hess, using pupilometry in 1972, experienced in some people the reactions that images of injured children provoked in his students, said that at first glance the images students grew due to agitation and shrunken quickly, wanting to avoid disturbing images. .
If you take pictures of politicians to show them to people, you may be able to understand their political inclination by observing the dilation of their students.
Barlow (1969) did a curious research selecting politically conservative and liberal people in the United States; when they saw liberal politicians, supporters of the same line had dilated pupils, while the eyes of conservative politicians contracted. it is also registered if it is not.
Some slightly sadistic researchers, such as Chapman (1999), applied small electric shocks to the hands of poor volunteers and measured pupil dilation. At maximum pain intensity, pupils dilate by about 0. 2 millimeters.
Some drugs, such as alcohol, cause students to contract, while others, such as amphetamine, cocaine, LSD, and mescaline, cause pupil dilation.
Watch students and you’ll be able to reveal and discover information about each person.
