The invention relates to medical technology and can be used during the professional selection of operators,.

The aim of the invention is to increase the credibility of the professional selection of operators by assessing their resistance to the action of factors in monotonous activities.

FIG. 1 shows a functional diagram of the proposed device; in fig. 2 - same 5 controls; in fig. 3 is a diagram of the second shaper; in fig. 4 is a block diagram analysis of FIG. 5 - schematic calculator.

The device for psychophysiological research contains a control unit 1, a second driver 2, a presentation unit 3, a response unit 4, an analysis unit 5, a calculator 6, a meter 7, the first driver 8, an input unit 9, a controlled switching unit 10, an indicator 11, generators. 12-18 counting pulses, coincidence circuits, binary-decimal counters 26-32, digital-to-analog converters 33-39, seven-channel control circuit 40, seven-channel decoder-shaper 41; signal generation circuit 42, random time interval generator 43, first single vibrator 44, second one-shot 45, first generator 46, first binary counter 47, second generator 48, first comparison circuit 49, second binary counter 50, first match 51, trigger 52, the first single-vibrator 53, the second trigger 54. Tium trigger 55, the second coincidence circuit 56, the first integrator 57, the even-r, the true trigger 58, rubbing the coincidence circuit 59, the second integrator 60, the first sample-storage unit 61, the first counter 62, first ADC 63, fourth circuit 64 coincidence and, the first dividing circuit 65, the first comparator 66, the rear coil signal generator 67, the fifth matching circuit 68, the second sampling-storage unit 69, the circuit 70 5; and differentiating, the third inverter 71, the sixth matching circuit 72, the analog switch 73 , rectifier 74, fifth trigger 75, seventh match circuit 76, sixth trigger 77, second formation circuit 78, seventh trigger 79, signal conditioner 80, eighth trigger 81, third counter 82, fourth integrator 83, second ADC 84, second 85 division circuit, third comparator 86.

The device works as follows.

The control unit 1, having received a signal from the analysis unit 5 about the completion of the task solution, begins preparation for the next task. After that, at a random time, electrical voltages are applied to the input of the information presentation unit 3, causing a brief flashing of the corresponding combination of seven simultaneously different digital symbols. The subject, after analyzing the perceived information, in accordance with the prescribed rule presses in a certain sequence on the seven buttons of the response unit. In block 5, possible errors are identified. It. accompanies, with an indication in the indicator 11, In addition, in block 5 the prescribed task particles are determined, which is indicated on the indicator 11. In block 5, the average solution time in a series of similar tasks is also determined, which compares with the threshold value specified by the block 9, will form at the output a corresponding signal when going beyond the permissible limits.

The calculator 6 and the meter 7 enumerate the values of the indicators, and also compare them with the threshold values given by block 9 with the subsequent generation of the signals to be displayed at the outputs of the blocks. The indication is carried out by the indicator 11 during the subsequent for the analyzed series of similar tasks. Managing the fixation of the displayed. signals by the switching circuit is carried out by the signal Confirmation of the shift coming from block 4 of the response reactions.

 When a second shaper of the sipnal appears in the block 3 at a random time, the signal lamp lights up, which lights up until the subject clicks on the eighth button Confirmation of the shift in block 4, which is also accompanied by the supply of control signals the input of the calculator 6 and the input of the switching unit 10.

The measurement of the average time of a simple visual-motor reaction in the meter 7 is carried out at the preliminary stage of the examination. At the same time, the operator being surveyed, in response to the turning on of the signal lamp in the block of 3 presentation of information, presses the Shift confirmation button. It. repeated 10 times. After that, the result is recorded with and used in the calculator when calculating indicators on the main stage of the survey.

The proposed device allows simultaneous evaluation of all the listed signs, identifying operators of monotonous factors that are resistant to the action, as well as carrying out differentiated professional selection according to the degree of expression of certain signs characterizing monotony.
