- Abstract
Long flight, conditions of the limited space, a gravitational field distinct from terrestrial, vibrations and other specific conditions influence on size of the sensorimotor reactions of cosmonauts. Theoretical solution of task about time of reactions on stimulus have allowed to take into account an influence of overloads on a constant of time T but it does not take into account functional asymmetry of hemispheres, important for extreme situations. Therefore the purpose of research was definition and comparison of relative parameters of sensorimotor reactions with a choice depending on a level of lateral asymmetry of hemispheres of a brain at representatives of various types of temperament. This parameters were by the bases for verification of theoretical dependence for the latent period of reaction in conditions of weightlessness and overloads. The hypothesis about influence of functional asymmetry to parameters of psychomotoric in sensorimotor reactions was laid in a basis of experiment. Techniques of definition of individual characters of the sensori-motor asymmetries were used and G. Ajzenk questionnaire EPQ adapted by Prisniakova L. In experiments participated 371 young men of 21 years, and among emotionally astable types of temperament of representatives with expressed righthemishere specialization was more, than among emotionally stable. Psychomotor parameters have been received by means of the computer test of measurement of time of reaction of decision making. It is shown, that time of reaction of decision making has significant distinctions between representatives of different types of temperament with a various level of the interhemishere asymmetry. The data are shown, that time of reaction is tending to reduction with increase in expressiveness of the right hemisphere at representatives of all types of temperament, the number of erroneous reactions grows and a level of achievement tends to reduction. A classification on distribution of structures of functional asymmetry and a ranking by time of reaction, by a quantity of mistakes and by a level of achievement for each type of temperament in reaction of decision making is offered in work. Results of time of reaction of decision making correspond with parameter of L. Prisniakova which characterizes individual psychological features. Conclusions. The experimental research has allowed to establish influence of the interhemishere asymmetry for gender and for age of the psychomotor features. Obtained magnitudes of both factors parameters temperament and hemishere’asymmetry of a brain has allowed to specify dependences of the period of reaction of cosmonauts from a weightlessness and overloads.
