A person has two hands, two legs, two eyes, two cerebral hemispheres. But it is only at first sight that a human being is a symmetric creature. Firstly, we have a leading hand, the right one with the majority of people, secondly, we have a leading eye. 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.
