Bondarenko M. Neurophysiological mechanisms of information processing under the conditions of its mono- and binocular perception

This fundamental research is expanding theoretical understanding of the mechanisms of monocular perception of emotional information, highlighting the role of the visual dominance in the process of switching of the attention. The experimental data on the role of dominant optic channel in the process of focusing attention indicated its active involvement into the suppression of answers to irrelevant stimuli and lack of inhibition of this response under the conditions of nondominant eye perception. The mechanisms of perception of affective information under the conditions of its irrelevance through the right open eye in dexters and the left open eye in sinistrals was shown for the first time. The mechanism of perception of emotional information through dominant and nondominant visual channel was described for the first time. It was shown that left-handers with dominant open eye performed tasks faster than left-handers with nondominant open eye. Subjects with dominant open eye (right-handers and left-handers) better focused on the current task, effectively inhibited irrelevant information and indicated more effective strategy of attention filters usage. These results are an important basis for further study of the neurophysiological mechanisms of monocular perception underlying the distribution of attention based on eye dominance and ensure effective strategies against diversion of attention for improving productivity.
