Human eyes pupil size is marker of intelligence

 

Atlanta: A new study has found a link between the pupils of the eyes and intelligence.  The pupil is called the black circular circle right in the middle of the eye, based on which the pupil has been measured and various brain tests have shed light on this relationship Human eyes pupil size is a marker of intelligence.

 In this way, it can be said that the eyes not only describe the condition of the heart and body but also prove the mental capacity.  Although dim light shrinks and spreads more or less, it also expresses fear, surprise, interest, and mental fatigue.  Police officers also use it to catch people lying.

 Scientists at the Georgia Institute of Technology have done some experiments in the laboratory.  The bottom line is that people with larger eyelids are just as likely to be intelligent.  Undoubtedly, this is a surprising revelation, which includes research from the 1970s.

 The study included 500 people aged 18 to 35.  All participants were measured with a blocker eye tracker.  Each person was then seated in front of a blank computer screen for four minutes and the pupil was measured in this way.  Thus, the average area of ​​each pupil is known.

 The pupil is usually two to eight millimeters long and is surrounded by a wide colored circle called the iris.  The pupil expands and contracts within itself, but the laboratory light is kept low during this time to keep the pupil normal.

 In the next stage, the participants underwent a test of cognition.  One test presented scientific reasoning for new problems.  In addition, memory tests were performed to remember the items for a while. Human eyes pupil size is a marker of intelligence   Attention and concentration tests were also performed, but attempts were made to divert attention and make noise.

 But keep in mind that the pupil of the eye gets smaller with age and that is why only people of a certain age are included in the experiment who are called young.  The study found that people with larger eyelids performed better than others in all three types of tests as if they were slightly more intelligent than others.

 Although the scientific explanation for the relationship between the pupil and intelligence requires further research, the idea is that there is a special link between brain-fired neurons and the pupil of the eye.  That is why one manifestation of mental activity can be through the retina.
