Description

one

The invention relates to engineering psychology devices and can be used for quantitative and qualitative assessment of a number of human psychophysiological functions (attention, memory, operational thinking, sensorimotorics, etc.) characterizing his work as an operator.

Psychophysiological research devices are known that contain the test subject's console, the experimenter's console, the program block associated with the control board, to which the time setting unit and the evaluation unit are also connected.

These devices are used to assess students' knowledge of the correct answer from several suggested packages within a predetermined time.

However, the accuracy of such devices is limited.

In order to increase the accuracy, an imaging device connected to the experimenter's and test unit's consoles, program blocks and time tasks and information boards made in the form of multi-segment sign indicators, and a distributor connected to the test panel, meter blocks and time tasks are introduced into the proposed device.

This makes it possible to form various abstract informational structures of tasks (tests) on the fields of information boards, as well as to change their content from the side of the experimenter's console and from the panel of the subject in the process of solving the task. In addition, it allowed for the production of operational assessment of the answers, analysis of the temporal parameters of the test responses and recording of the results.

The drawing shows a block diagram of the proposed device.

It contains information boards 1 and 2, the imaging unit 3, the panel of the test 4, the experimenter's console 5, the program block 6, the time setting block 7, the distributor 8, the counter block 9, the analysis block 10, the AND block and the control boards 12, 13.

Information boards 1 and 2 are made on multi-segment sign indicators (for example, electroluminescent), which are located on them in the form of rows and columns (as shown in the drawing). The position of each sign indicator on the placards is determined by the X and Y coordinate indices, denoting the row and column numbers. The numbering of the segments of sign indicators based on a specific algorithm is specified by the coordinate index C.

Information board 1 serves to present the subject with tasks (tests),

and information board 2 for remote visual monitoring of the change in the content of the task during the test and for the experimenter’s self-control during the preparation of the tasks.

The device uses ge-segmeptny sign indicators. On each of them, 2 abstract symbols can be formed, on the basis of which 1 and 2 task texts are compiled for examining various functions: attention, memory, operational thinking, etc.

The segments of the iconic indicators of the scoreboard 1 and 2 are connected to the outputs of the imaging device 3.

The first information outputs of the panel of the test 4, the experimenter's console 5, the program block 6 and the output of the command signals of the time setting block 7, which are connected in parallel to the distributor 8, are connected in parallel to the imaging unit 3. The second information outputs of the test panel of the tester 4, the experimenter's console 5, program block 6 As well as the information outputs of the time setting unit 7 and the counter unit 9 are connected to the analysis unit 10, the information output of which is connected to the registration unit 11. The signal output of the analog block 10 is connected to the control boards 12 and 13, and the command is connected to the program block 6, to which the command outputs of the experimenter’s console 5 and the time setting unit 7 are also connected. The third information outputs of the experimenter’s console 5 and the program block 6 are connected to the time setting unit 7, signal output connected to the control boards 12 and 13, to which the signal outputs of the test and experimenter’s consoles are also connected.

The clock output of the test panel is connected to the distributor 8, the output of which is connected to the block of counters 9. The second information output of which is connected directly to the registration block 11.

The panel of the subject serves for a set of coordinates of the answer X, Y and С when solving tasks.

The experimenter's console serves for manual programming of the texts of tasks on information boards 1 and 2, programming answers for solving tasks by a set of segment coordinates, time parameters and control of program block 6.

The program block 6 is used to read the punched tape of the examination program.

Block 7 sets the time modes of the device operation: "Presentation Time," Decision Time, and "Pause Time.

The block of counters 9 is used to measure the time intervals of the responses of the test when solving tasks.

The analysis unit 10 is designed to analyze the answers of the test person, to determine (for each task) statistical indicators

performing test response time responses, encoding and distributing the obtained processing results and outputting them to the recording unit 11. In addition, the analysis unit 10 generates command signals for controlling the program unit 6, as well as the signals for the control boards 12 and 13.

The recording unit I serves for outputting the results of the investigation onto a punched tape, which are then intended to be entered into the computer.

The device works in manual and automatic modes. In manual mode, the formation

tests on information boards 1, 2 are made from the experimenter's console through the imaging unit 3 and are simultaneously output to the analysis unit 10. Control over the correctness of the character set is made

according to the indicators of the control panel 12, and the comparison of the entered characters in the imaging unit 3 with the model of the task is made according to their images on the information board 2.

The time parameters set by the Presentation Time and the Decision Time are set on the experimenter's console. When the device starts, the command and code signals of the set time parameter

come from the experimenter's console to the time setting unit 7, and according to the command signal, it starts counting the current time and in parallel the circuit board of information board 1 is switched by the imaging unit 3.

The task text is presented on the information board 1, the time parameter from the time task block 7 is output to the analysis block 10 and from it to the registration block 11.

After a predetermined time has expired, a command signal is generated in the task time block 7, which in parallel arrives at the inputs of the imaging unit 3, the distributor 8, to the reset bus of the task block

time 7, from the second output of block 7, the command signal arrives at the experimenter's console 5. In this case, the imaging unit 3 removes the text of the task from the information board 1, the distributor 8 includes

the block of counters 9, and in the time setting block 7, the time parameter information is reset and at the same time the next parameter information is requested from the experimenter's console - the decision time, which is likewise recorded in the time setting block 7 and output in parallel to the analysis block 10.

When performing response from the test panel, a signal is sent to the input of the distributor 8, which outputs the measured time interval “Decision time” to the analysis unit 10 and in parallel to the registration unit 11. The interval “Response time,” which is output to the analysis units 10 and

registering 11 by the end of response signal from the control panel of the subject.

At the same time, the code signals of the test panel’s response go to analysis block 10. If the answer was correct, then in analysis block 10, the number of correct answers increases by 1, which is displayed on the control boards 12 and 13. Otherwise, in the same block it increases by 1 the number of erroneous answers, which is also displayed on the control boards 12 and 13.

In the process of performing the response, the subject controls himself by demonstrating the indicators of the control panel 13, which receive signals from the test panel and, if an error is detected, can correct it before the end of response signal.

After a predetermined time interval has expired, a decision signal is generated in the time setting unit 7, which is sent to the control boards 12 and 13, to the input of the imaging unit 3 and to the input of the analysis unit 10. As a result, the end time signal is displayed. The imaging unit 3 turns off the sign indicators of the scoreboard 1, and the analysis unit 10 proceeds to processing the statistical performance indicators of the task: the number of responses completed, the relative ratio of correct answers, the average time per response operation, the actual time the task was completed and others, which are then output to the block registration 11.

In the automatic mode of operation, after the experimenter starts the program block 6, the task text is output from it to the imaging unit 3, the programmed responses to the analysis unit 10, the time parameters to the time task unit 7, and the necessary service commands to the inputs of the same blocks. The time 7 entered into the task block and the analysis block 10 information is output to the registration block 11.

During the operation of the device, the programmed time parameters are sequentially called from program block 6 by command signals from time task block 7, which are generated in it after the previous time parameter entered. Thus, after the time parameter has elapsed, the Pause Time is switched on at block 6, and from it the information of the subsequent task is entered into the corresponding blocks.

Depending on the conditions of the task, the analysis unit 10 is set to one of two possible modes of monitoring the responses of the test person: the "Dependent sequence mode or the" Arbitrary sequence. The "Dependent sequence" mode is used for those tasks that require a chain of answers from the subject in a strict sequence. Mode

"Arbitrary sequence is applied to tasks that do not require a strict sequence of answers. In this case, for the Dependent Sequence mode, the subsequent programmed answers are in program 6 block and are called into analysis block 10 when the subject performs the previous answer, and for an arbitrary sequence, all the answers of the task are stored in analysis block 10 and are compared with each answer in parallel .

In the automatic mode of operation of the device, the response of the subject (processing and recording his time and accuracy response parameters) is carried out similarly to that described in the manual mode of operation, and the functions of the experimenter are reduced to monitoring the proceeding processes on the control board 12 and the information board 2.
