Psychophysiological Indicators of Young People with Signs of Internet-Addiction

Abstract

<p>The purpose of this work is to study the psychophysiological features and characteristics of the activity of the central nervous system in young people with signs of Internet addiction. Young people were investigated, students of grades 10-11 of Tyumen gymnasiums, as well as students of 1-3 courses of Tyumen State University were studied. Internet addiction was determined by the Chen test, the average screen time spent online using mobile gadgets was recorded, the level of anxiety was determined when modeling the symptom of network access cancellation. Cognitive plasticity was determined by the Stroop method. The properties of the central nervous system were studied using a Symbol Cancellation Test (Landolt rings), the critical frequency of the fusion of flickers, the time of simple and complex visual-motor reactions were measured. The following results were found: in gymnasium students with signs of Internet addiction, significant cognitive rigidity was recorded in congruent (1.19 &plusmn; 0.05 s per solution; p&lt;0.01 with control) and non-congruent (1.49 &plusmn; 0.08 s per solution; p&lt;0.001 with control) Scab samples, respectively. In the group with Internet addiction, low reliability of work on the Landolt test was also noted (Kp 16.24 &plusmn; 2.09%; p &lt;0.001 with control), low accuracy of work (At 0.76 &plusmn; 0.03 units; p &lt;0.001 with control) and more inert indicators of complex visual-motor reaction (436.66 &plusmn; 14.52 ms; p&lt;0.001 with control).The most pronounced negative characteristics associated with low reliability of information processing, low endurance and ability to differentiate in the central nervous system, as well as reduced selective perception of information were noted in the group of gymnasium students and, in part, in the risk groups of gymnasium students and students.</p>
