In device for method realisation to central control unit connected are unit of measuring SMR time, connected with input device, and connected with unit of SMR time measuring analysis unit which includes connected successively connected unit of state indices calculation, analysis and evaluation unit and unit of selecting energy stimulation program, and memory unit contains unit of storage of operator individual indices storing, and unit of storing estimation and energy stimulation programs. As units of stimuli impact, unit of electric current, unit of sound influence and unit of light (colour) impact.
EFFECT: invention allows to increase correction efficiency and prevent aggravation of person's state before the moment comes when they are not able to fulfill vested functions.

EFFECT: method allows to reduce time of analysing, due to which can be applied in mass examinations or in process of testing by bicycle ergometry for evaluation of person's tiredness degree or their functional state.
SUBSTANCE: circumference with mark on it and point object moving on circumference with set rate are shown on videomonitor screen. At the moment of supposed coincidence of point object position with mark tested person stops movement of point object on circumference pressing "Stop" button. At this moment error of non-coincidence of point object and mark is calculated - time of lag error with positive sign or forestalling error with negative sign, and after set time movement of point object on circumference is recommenced. Described procedure is repeated determined number of times, after which time of person's reaction on moving object Tp is calculated by formula: where ti - i-th lag error with positive sign or forestalling error with negative sign, msec; n is number of point object stops in region of mark location.
EFFECT: method allows to increase reliability of reaction time.

SUBSTANCE: invention relates to medicine, in particular to labour hygiene and prevention of professional diseases, and can find application in selection of personnel for operator professions according to the level of psychophysical indices level. Tested person is examined by means of complex of psychophysiological procedures and Cattel test, determined are indices of brain workability, logical thinking, steadiness of nervous processes, attention, ability for prediction, operative thinking, long-term memory, rate of proceeding of thinking processes during operation with number material, as well as indices C and Q3 by Cattel test. Indices in form of ratio of number of correctly done tasks to spent time are used, and tested person is considered suitable for operator work if number of mistakes made by them while fulfilling procedures does not exceed four, than allowable values of evaluated indices.
EFFECT: method allows to evaluate professional appropriateness of tested person for operator work immediately after psychophysiological examination and select the most promising candidates for working places.

SUBSTANCE: invention refers to medicine, namely to physiology and psychophysiology, human ecology, and environmental geology. An image is formed of k-horizontal lines sized of less than a half of coverage width of one eye. Each line includes L symbols of width qj spaced by Δqj not exceeding qj. Groups of symbols spaced by Δpk much exceeding qj are formed. The horizontal lines are arranged so that spaces Δpk in each horizontal line are overlapped herewith forming vertical character sets. The image effects on visual system while being moved from one extreme eye coverage to another. Depth sensation between two vertical character sets is determined to detect visual sensation of direction change in depth vector in-between.
EFFECT: method extends range of products to detect new neutron networks of human cerebral cortex.
SUBSTANCE: electrodes of electric ECG potential registration are placed in zone of aorta and in zone of cardiac apex. Changes of electric potential on body in time are registered in form of diagram of ECG function. Near each electrode of ECG electric potential registration additional electrode is installed, onto which high-frequency signal from generator is supplied, and from electrodes of ECG electric potential registration modulated by fluctuations of arterial blood flow signal is obtained synchronously, said signal is amplified, converted into digital code and transmitted for rheogram registration to information processing unit, after which connection of ECG electric potential with change of pressure according to rheogram is connected in each phase, and phase peculiarities of arterial pressure change are diagnosed. Device for synchronous registration of rheogram from ECG electrodes consists of two ECG electrodes, commutator, first amplifier, first band filter, analogue-digital converter, controller, IR transmitter and information processing unit with first detector, commutator being inserted between electrodes and first amplifier, whose outlet through band filter is connected with first inlet of analogue-digital converter, whose outlet is joined to controller, whose first outlet is connected with commutator, and second outlet - with IR transmitter, connected with first detector of information processing unit. Two additional electrodes, second amplifier, second band filter, second detector and generator, switched to additional electrodes, are introduced into it, second commutator outlet is connected to inlet of second detector, whose output through second amplifier and second band filter is connected with second inlet of analogue-digital converter.
EFFECT: synchronous registration of phase characteristics of cardiac cycle and corresponding fluctuations of arterial pressure in heart vessels and aorta.
