Thirdly, the brain is functionally asymmetric: the left hemisphere (with the right-handers) is mainly connected with abstract-logical thinking and to a larger extent - with speech, the right hemisphere – with image sensitivity.
Coming back to eyes, the right eye is the leading one among the two thirds of people, and the left one among one third of people. Special tests have been developed to determine this. Do these individual differences influence the visual information perception process, for example, perception of texts, on the left and on the right? Investigations carried out at the Institute of Cognitive Neurology of the Modern University for the Humanities will help to answer this question.
The experiment involved all right-handed students, but some of them had the right eye leading, the others – the left eye leading. All probationers were offered to read a text on the PC screen, the text being placed either in the right or in the left part of the screen, while the probationers’ head was oriented to the center (in such conditions, visual information from the left half-field of vision was addressed to the right hemisphere, and vice versa). It has turned out that the “left-eyed” probationers read the text quicker when it is placed on the left, than the text placed on the right. As for the “right-eyed” individuals, no such differences were noticed with them.
In other words, in the left half-field of vision, glance fixation is characterized by higher “information capacity”. This is directly connected with the speed of reading: the more symbols the glance perceives during one fixation, the quicker a person reads. There is one more sign of successfulness of reading: in the course of reading, the glance periodically returns back to the already read word (apparently due to difficulty of perception). Thus, in the left-sided text, the “left-eyed” probationers made less returns than they did in the right-sided text, which means higher successfulness of the “left” text recognition. Besides, the majority of the “left-eyed” persons performed faster quick eye movements – saccades – to the left than to the right.Physiologists can only make assumptions about the reasons for such differences.
And this works out better. Therefore, the “left-eyed” persons read quicker on their left.
Where can this knowledge prove useful? Apparently, it makes sense to take the leading eye into account for production of various video-products, for example, training ones. Special objects (spoons, door-handles) are produced, even though not in Russia, for the left-handed, but there is nothing special made for the “left-eyed” persons. Maybe this will be done in the future.
