The study is devoted to the study of the relationship between stress caused in students by social isolation and the ability to switch tasks as one of the basic functions of attention. The study draws on the theoretical background of The Attentional Control Theory as the most appropriate method to study the factors influencing attention control under the influence of the effects of stress. The experiment includes a sample of 76 Chinese university students who experienced forced social isolation for 6 months. A statistically significant increase in physiological markers of stress was found in both cases, indicating that social isolation leads to an accumulation of stress and an increase in the intensity of stress reactions when students reexperience social stress after isolation. The practical significance lies in changing the approach to coping with the results of social isolation stress in students through changing the method of presenting educational information.
