METHOD FOR PSYCHOLOGICAL TESTING OF HUMAN OPERATOR

FIELD: medicine.SUBSTANCE: rested and fatigue person being tested is presented with variable-frequency signals formed as test to be solved, a presentation rate of which is changed proportionally wto its solution rate, and a quantity is specified equal for the rested and fatigue person being tested. Response measurements of the person being tested on the presented signals; a degree of fatigue measurements variation are described by expressions Tav.f=Ttotal.f/Kcor.f, Tav.r=Ttotal.r/Kcor.r, wherein Tav.f is an average time for correct solution of one test in the fatigue state. Tav.r is an average time for correct solution of one test in the rest state, Ttotal.f is the total time for solution of the pre-set quantity of tests in the fatigue state, Ttotal.r is the total time for solution of the pre-set quantity of tests in the rest state, Kcor.f is the quantity of the correct tests in the fatigue state, Kcor.r is the quantity of the correct tests in the rest state. A sequence of the presented tests in the rest and fatigue human operator is pre-set equal; an average time for one correct test in the rest human operator (Tav.r) is determined by a limited quantity of 3-5 series of 10 tests and used as a reference for further examinations. The tests to be solved include logical and dynamic tests performed by the operator together with a machine. A time for performing each test is determined taking into account repeated solutions required to correct the result and to fulfil the accuracy requirements of the specific test. The psychological tests involve measuring the human operator's physiological parameters. If at least one of them goes beyond admissible levels, the human operator load is reduced by limiting the quantity of tests to be solved in the fatigue state. A degree of the human operator fatigue variation is assessed taking into account limiting the quantity of tests by a relative variation of an average time of the correct solution of the tests in the fatigue state, and respective analogous tests in the rest state.EFFECT: method enables providing higher reliability ensured by increasing psychological, mental and lower visual component of the load, higher safety of the human operator in the process of examination and reducing time and material costs when implementing the method.2 cl Изобретение относится к области медицины, а конкретно - к технике измерения психофизиологических характеристик.
