In this case, the trigger 25 and the counter 9 are reset, the reversible counter 19 is set to the All units state, and the indicator 15 of the moving object returns to the initial state. The signals of the forward state code of the counter 9 through the decoder 10 are fed to a digital indicator 11, in all bits of which the devices in the initial state are indicated by zeros. From the generator output 12 clock pulses to the counting input of the counter 13 with a variable conversion factor receive clock pulses constant this frequency. The control input of the counter 13 with a variable conversion factor receives a digital signal of the forward code of the reversible counter 19,

sag the output of which is the output

block 7. Input 28 is a device input.

The device works as follows.

At the input 28, the device sets the pulse to the initial state. In this case, the trigger 25 and the counter 9 are reset, the reversible counter 19 is set to the All units state, and the indicator 15 of the moving object to the initial state. The signals of the forward status code of the counter 9 through the decoder 10 are fed to a digital indicator 11, in all bits of which zeroes are indicated in the initial state of the device, From the generator output 12 clock pulses to the counting input of the counter 13 with a variable conversion factor clock pulses come frequencies. The control input of the counter 13 with a variable conversion factor receives a digital signal of the forward code of the reversible counter 19,

determining in the initial state of the organizer the maximum possible conversion factor for it, corresponding to the minimum level of complexity of the upcoming test task. The reverse status code of the reversible counter 19 through the decoder 18 enters the digital indicator 17 of the test task complexity, in all bits of which is in the initial state

devices are indicated by zeros. From the first output of the trigger 25 to the second input of the logic element And lk, a logical zero is applied, which prevents the passage of pulses from the output of the counter 13 with a variable conversion factor to the input of the indicator 15 of the moving object, the arrow of which is stationary in the initial state.

The key being tested by pressing the key 26 acts on the pulse shaper 27, the signal of which goes to the subtracting third input of the reversing counter 19 and sets the recalculation coefficient of the counter 13 with a variable recalculation coefficient in accordance with the task complexity that the test is supposed to perform. The digital code of the current task complexity from the inverse output of the reversible counter 19 through the decoder 18 enters the input of the task complexity indicator 17 and is indicated to the subject. Next, the person under test by pressing the key 21 acts on the pulse shaper 23, from the output of which a signal is inserted at the second input of the trigger 25, which sets the trigger 25 to the state of a logical unit. In this case, from the first output of the trigger 25 to the second input of the logic element AND I, a signal of the logical unit is applied, which allows the pulses to pass from the output of the counter 13 with a variable conversion factor to the input of the indicator 15 of a moving object, the object of which begins its movement at a speed proportional to the digital code of the current the complexity of the task. In accordance with the instruction, at the moment of coincidence of a moving object with a zero position of the scale, the subject presses key 20. Pulse shaper 22 generates a signal that, through the first input of the OR 2k logic element, arrives at the first trigger input 25 and resets it. From the first output of the trigger 25, the logic zero signal is fed to the second input of the logic element I 1 and blocks the passage of a pulse from the output of the counter 13 with variable coefficients

If the moving object at the time of stopping by its key 20 is outside the experimental tolerance tolerance predetermined by the experimenter, from the output of the indicator 15 of the moving object to the first input of the logical element I 1b a signal of the logical unit is received. As a result, the output of block A produces a signal that goes to the summing input of the reversible counter 19 and to the first input of the logic element 8. At the same time, the state code of the reversible counter 19 is increased by one, which increases by this value the counter conversion factor 13 with a variable conversion factor, reduces the pulse frequency at the first input of the AND gate and reduces by one point the code of the current difficulty of the task indicated on the indicator 17. If the subject does not agree with the decrease ozhnosti Representat present experimental specifying one point, it can increase it at any permissible number of points using the key 26, since according to the instructions of the test object is the achievement for the entire series of jobs for which the maximum possible number of points. In this case, the state code of the reversible counter 19 will change its state in the direction of decreasing the conversion factor of the counter 13 with a variable conversion factor and the frequency of the pulses at the first input of the logic element 14 will increase. At the same time, the counter status code 9 will increase its state by the number of points equal to the number of keystrokes by the operator 26. Next, the subject presses key 21 and proceeds to the next experimental task.

An indicator of a person's risk appetite is the sum of points accumulated by the counter 9 points for the total time of the test and indicated by the digital indicator 11 points to the experimenter.
