Abstract
Aim: the aim of this article is to estimate the functional condition of the central nervous system in students under the influence of weakly structured information on the parameters of sensorimotor reactions. Materials and methods. We examined 97 female students with the average age of 19.2 ± 1.2 years. We estimated physiological effects of the influence of weakly structured information (WSI) in the conditions of doing tasks with increased demands to the manifestation of verbal intellect. The lack of instruction for doing the task characterizes work with information as a weakly structured. The WSI model is based on the Wechsler’s method. We registered the combination of physiological effects in response to the influence of WSI using NS-Psychotest computer appliance. We conducted tests (Common hand-eye reaction and Reaction to a moving object) just before and after the influence of WSI. We analyzed the latent time of common hand-eye reaction and the parameter of functional condition of the central nervous system: functional level of the system, reaction stability, level of functional capacities, and the quantitative parameters of the accuracy of motor reactions. Results. The informative parameters of the central nervous system reactivity of students in the dynamics of performing the tasks on WSI processing are quantity of accurate reactions, functional level of the system (FLS), reaction stability (RS) and level of functional capacities (LFC). We revealed the peculiarities of the central nervous system reactivity in students under the influence of WSI. The manifestation of psychomotor functions under the influence of WSI in persons with the different level of the functional mobility of nervous processes and reaction accuracy are registered in different functional conditions: readiness is revealed in persons with the mobility of nervous processes and high accuracy of reaction; mobilization is revealed in female students with the pronounced inertia of nervous processes and high accuracy of sensorimotor reaction together with the insignificant decrease in the level of functional capacity. Conclusion. We established that the influence of WSI on body is accompanied by the formation of functional system realizing the variant of the central nervous system reactivity. The sequence of the development of reaction mobilization or readiness is determined by the different ratio of the functional mobility of the nervous processes and accuracy of sensorimotor reactions.
