Attentional bias is a major component of perception and may reflect the effects of emotional stress. However, little is known about the characteristics of attentional fixation in the early stages of the development of anxiety disorders. </em></p> <p><em>The goal. To identify bioelectric markers of attentional shifts in young people student volunteers. </em></p> <p><em>Methods. The dot test was used in tests with neutral-negative and neutral-positive sets of images. During the test period, the reaction time to the point was recorded, and an electroencephalogram was recorded, from which evoked potentials were then extracted. </em></p> <p><em>Results. Based on reaction time, the subjects were divided into 3 groups: 1st group with a faster reaction to dots after a threatening picture, 2nd - with a faster reaction to dots after a neutral picture, 3rd - with the same reaction time to threatening and neutral visual information. However, no significant differences were recorded in reaction times to neutral-positive pictures. Young people with rapid reactions to visual information with an alarming value are characterized by an early P120 component in the parieto-occipital leads, presumably reflecting the mechanism of primary processing of visual information, and an N100 component in the frontal leads, associated with early recognition of visual information. </em></p> <p><em>Conclusions. P100 and N100 are associated with the distribution of automatic attentional resources and can be used as bioelectrical markers of distortions in cognitive processes associated with attentional shifts in the early stages of the development of anxiety and emotional stress. </em></p>evoked potentialsattention shiftbioelectric markersanxietyemotional stressвызванные потенциалысмещение вниманиябиоэлектрические маркерытревожностьэмоциональный стресс1.Mathews GR, Antes JR.
