Prospects of visual evoked potentials latency application in psychophysiology

Aim. The aim of this article is to estimate the influence of visual analyzer on a person’s psychological well-being. Materials and methods. The study involved 120 people aged 18-20 (60 boys and 60 girls). Registration of visual evoked potentials was carried out with the help of Neuron-Spectrum-4 / P 21-channel digital electroencephalograph (Neurosoft Company, Ivanovo) and the corresponding software. Characteristics of subjective well-being were determined with the help of the following methods: M. Fordyce Happiness scale; Lyubomirsky Subjective happiness scale; E. Diner Satisfaction with life scale. Statistical processing of the results was performed comparing latency indicators in groups with high and low psychological values. We also calculated odds ratios (OR) and the boundaries of their confidence interval. Results. We established a pronounced association between the increased latency of the components of visual evoked potentials and low satisfaction with life. Conclusion. We revealed a dependency between the evoked potentials latency indicators of visual analyzer and well-being characteristics. We also demonstrated practical significance of the patterns revealed, which can be used to forecast ill-being using the results of visual analyzer diagnostic.
