 The first and second output of the generator 1 is connected respectively to the counting inputs of the counters 7, 8 and 11, 12. The S-input of the first trigger 2 and the S-input of trigger 3 are connected and connected to the "Start" bus. The output of trigger 2 is connected to the enable input of the counter 7, the outputs of which are connected to the first inputs of the comparison element 13, the second inputs of which are connected to the outputs of the code switch 28. The direct output of the trigger 3 is connected to the counting input of the counter 10, the outputs of which are connected to the decoder 17 of the third display unit , the inverse output of trigger 3 is connected to the second inputs of the first element OR 21 and element And 27, the second inputs of which are connected and connected to the output of the fifth trigger 6, the S-input of which is connected to the output of the first element 13. The output of the first element OR 21 is connected to the S-input of the trigger 4, the R-input of which through the second element OR 22 is connected to the output of the element 27 and the S-input of the trigger 5, the output of which is connected to the resolution enable input of the counters 9, 11, 12 The output of the trigger 4 is connected to the input of the resolution of the counter 8, the outputs of which are connected to the first inputs of the second comparison element 14, the second inputs of which are connected to the outputs of the counter 11, the R-input of which through the OR element 23 is connected to the output of the second comparison element 14 and the counter input of the counter 9, the outputs of which are connected s with the inputs of the decoder 16 of the second display unit. The bus "Zeroing" is connected to the R-inputs of the counters 7.8 and the PE-input of the counter 12, the R-input of the trigger 6 and through the elements OR 22, 24, 25, 26 with the R-inputs of the triggers 4, 5, 3, 2, respectively the second input of the OR element 25 is connected to the bus "Stop".

 The code switch can be, for example, of the type ПП10-3РПВ counter 12 can be performed on the chip 564IE15.

 The device operates as follows.

 The operation of the device begins with the installation of the counters 9, 10 in the initial state by the signal "Reset" and installation in the initial state by the signal "Zero" of the counters 7, 8, 12 and triggers 2, 3, 4, 5, 6.

On the code switch 28 set the control number equal to T _about .

 Using the code M, the number 12 is entered into the counter 12, which is selected based on the convenience (clarity) of the reaction score.

 After pressing the Start button, triggers 2 and 3 are set to a single state. The signal from the direct output of trigger 3 enters the counting input of counter 10, which counts the number of attempts (starts) of measurement and the first "1" is written into the counter. Potential level "1" from the output of trigger 2 allows the pulse count from generator 1 to counter 7 (time counter), the status of the counter is displayed by indicator 18.

In all cases, after pressing the "Start" button, counter 7 runs one cycle until zeroing. When the overflow signal F 2-exit trigger counter 7 via an OR gate 26 is set to "0" and prohibits the count of the counter 7. The subject who observes the state counter 7 real time Tx _of the indicator 18 serves to push the button "Stop" thus so that the difference T _about -T _{x is} minimal. Three cases are possible depending on the magnitude of the difference.

The "Stop" button is pressed after the coincidence of T _o and T _x , i.e. after the counter 7 counts up to the number T _{about the} delay.

The Stop button is pressed until T _x and T _o coincide, i.e. before the counter 7 counts to T _{about the} lead.

 The Stop button is pressed after counting by the counter 7 of the maximum possible number determined by the volume of the counter 7.

 Consider the first case. The Stop button was pressed late.

In this case, when the counter 7 counts to the number T _о , which is dialed on the code switch 28, the comparison circuit 13 generates a signal that sets the trigger 6 to state "1", this signal through the OR element 21 is set to state "1" trigger 4 , allowing the count of pulses from the generator 1 counter 8 and allows the operation of the element And 27 at the first input.

When the “Stop” button is pressed through element 25, the signal enters the R-input of trigger 3 and sets it to the “0” state. From the inverse output of trigger 3, the signal through the And 27 element and the OR element 22 sets the trigger 4 to "0" and prohibits the pulse counting by the counter 8. In addition, the signal from the output of the And 27 element sets the trigger 5 to the "1" state and allows the counters 9 to work , 11, 12. In this case, the value of the interval Δ ТТ _х Т _о | the so-called magnitude of the module, where T _{about the} control number;
T _{x the} number that is in counter 7 at the time you click the Stop button.

 After the resolution signal, pulses from the generator 1 arrive at the counting input of the counter 11 after the resolution signal. The current value of the counter 11 goes to element 14, where it is compared with the value of the module Δ T counted by counter 8, if these values are equal, the comparison element 14 generates a signal, according to which, to the counter 9 the first "1" is written and the counter 11 is reset. The counter 11 will again begin to read the value of the module Δ T, and the counter 12 will continue to count, the cycle will be repeated until the counter 12 counts to the number C recorded in it. Upon reaching the number C with an overflow signal from counter 12, trigger 5 is set to the “0” state and prohibits counting by counters 9, 11, 12.

показывающий сколько раз в число С укладывается модуль Т.In this case, the result P will be recorded in counter 9

showing how many times the number T fits into the module T.

С, т.е. максимальное число баллов, а если испытуемый нажмет "Стоп" при значении Т_х Т_о + С, то результат в счетчике 9 Р

1 минимальное число баллов.If the subject pressed the “Stop” button very close to the number Т _о , for example, the difference is 1, Т _о + 1, then in the counter 9 the number of “points” will be recorded, evaluating the reaction of the subject, equal to Р

C, i.e. the maximum number of points, and if the subject clicks “Stop” at a value of T _x T _o + C, then the result in the counter is 9 P

1 minimum number of points.

It follows that the capacity of the counter 7 is calculated based on T _xmax T _o + C + 1.

Consider the second case, the “Stop” button is pressed until the values T _o and T _x lead coincide.

In this case, by the signal "Stop" trigger 3 is set to "0" and the signal from the inverse output through the element OR 21 sets to "1" trigger 4, which will allow the counting of pulses from the generator 1 counter 8 (module Δ T). When the counter 7 counts to the number T _o , the comparison circuit 13 will generate a signal that sets the trigger 6 to the "1" state and through the And 27 element, enabled by the second input by the signal from the inverse output of the Trigger 3, and the OR element 22 will set the trigger 4 to " 0 "and stop counter 8.

 In addition, through element And 27, trigger 5 will be installed in "1", which will allow the formation of the result of the reaction assessment using counters 9, 11, 12. As described above.

Consider the third case, when the magnitude of the module Δ T> C, i.e. when the value of T _about is separated from the value of T _x by an amount greater than the number C, Δ T> C. In this case, the device operates in the same way as in the first case, but until the "Stop" button is pressed. When the “Stop” button is pressed, the counting in counter 8 will end and the counting in the counters 9, 11, 12 will be resolved. The first will end the counting in counter 12, which will count to the number C and overflow through the OR element 24, set trigger 5 to “0” and stop counters 9, 11, 12.

 Since the counter 11 does not count to the value of the existing module, the comparison element 14 does not produce a signal and the "offset" of the result in the counter 9 will not occur, i.e. the result will be 0.

P_i Результаты подсчета счетчиков 9 и 10 отображаются на индикаторах 19, 20.The device allows you to evaluate the test subject’s response for several attempts, while the test subject presses the “Reset”, “Start” and “Stop” buttons in each sequence on a new attempt. As a result, the counter 10 will count the number of attempts K, and the counter 9 the total result of points P _Σ

P _i The counting results of counters 9 and 10 are displayed on indicators 19, 20.

 The frequency of the signals from the generator 1 to the counters for calculating the result 11, 12 exceeds the frequency of the real-time signals arriving at the inputs of the counters 7, 8. This is done so that the result is generated imperceptibly quickly, almost simultaneously with the click of the Stop button.

 The proposed device allows you to calculate the result of measuring the reaction in points, which increases the information content in the assessment of the reaction, and expands its functionality, applying for children's education, training, and is of interest to the game.
