Description

I12

The invention is applicable to melicinical techniques and can be applied to automate the processing of information obtained during psychological tests in neurology, psychiatry, labor examination, in professional practice, as well as in educational devices. for various purposes

The purpose of the invention is to increase the speed of testing.

Fig. 1 is a block diagram of a psychological research device; FIG. 2 is a block diagram of a switch.

The device contains buttons 1 and 2 for selecting values of the Yes type and trigger 3, the IGSh 4 element, 5 clock pulses shaper, two permanent memory devices (ROM) for storing the standard Yes 6 and No 7 type answers, ICHSH element 8, counter 9 values of the scales, ROM 10 threshold values of the scales, switch 11, select the type of test group, switch 12, counter

13 numbers of scales, button 14 for selecting .kals; adder 15, key 16 ,, indicator 17,

Button 1 is connected to one of the inputs of trigger 3 and the element OR 4, button 2 is connected to another input of trigger 3 and the element OR 4. The output of trigger 3, corresponding to the answer

Yes (t, e, the output at which the value of the logical unit is set after pressing the 1 Yes button) is connected to the inputs of all the first I elements included in the logic elements 8 I-IPI, the second inputs of which are connected to the outputs of the ROM 6. The trigger output 3, corresponding to the answer No, is connected to the inputs of all BTOpbDi elements And the same logical

elements Pi-I-fflH 8, the second inputs of the co-Topbts: are connected to the outputs of ROM 7, Vzhod each, of the element I-ISHL 8 are connected to the counters with counters 9 values of psychological scales, the same outputs of which through the switch 12 are connected to the sum of the lateral 15 The number of elements OR-8 and counters 9 is equal to the number of psychological scales used, Other inputs of the sensor 15 through the switch 11 to select the type of the group of subjects are connected to, the outputs of ROM 10, the sum-; torus 15. is connected to the control input of the key 16, and its information

entrances as well as control inputs of the commutator | 12 and 12 are connected to the counter outputs 13 numbers of psychological scales. Counter input 13 connect 1en

button 14 select the scale. The output of the element OR 4 is connected to the input of the imaging unit 5-5 which is connected to the ROM 6 and 7.

The switch 12 consists of multiplex lexors 18. FIG. 2 shows the structure of the switch 12 and the nature of its connections with the counters 9, the adder 15 and the counter 13. FIG. 2 corresponds to the case when the number of n psi5 hologkical scales does not exceed sixteen (if n is more than 16, the second level of multiplexers is organized), the outputs of the first of counters 9 (in which the value of

0 of the first psychological scale) are connected to all first inputs of multiplexers 18 - the first output is connected to the first input of the first multiplexer; the second output is connected to the first

S input of the second multiplexer, etc. The outputs of the counter 13 are connected to the control inputs of all the multiplex execors 18. The outputs of the multiplexers 18 are connected to the inputs of the adder

0 The device operates as follows.

Test, having received the texts of the questions ps. Ichological questionnaire by pressing the buttons 1 and 2 selects the answer. Yes or No for each vogphos. When the 1 st one of these buttons is pressed, using clock 4 and 5, a clock pulse is formed and from ROM 6 and / I select binary words

respectively, where k is the number of psychological scales used. i is the number of the test question in the questionnaire. The value of psychological scales is calculated using the elements I-1-SHI 8 and counters 9 o

The situation is acceptable (the subject cannot answer the same question and Yes and No)

The contents of ROM 6 and 7 are determined by the specific content of the questions (the content of the questionnaire). After this, (as the test responded to all the questions of the psychological questionnaire, in each of the enumerators 9 a number equal to the value of the corresponding psychological scale for the subject was recorded. Further operation of the device is associated with a comparison of the psychogram (; set of values of psychological scales) of the subject with the maximum normative (threshold) data stored in the IZU 10. To do this, using switch 11, the subject chooses a group of people (profession) for which it is necessary to make a comparison, and Press button 14. Each press of button 14 causes the contents of counter 13 to increase by one. The number in counter 13 is equal to the scale number used for comparison.

ienie. This number controls the selection of the channel of the switch 12, through which the output of the corresponding lean counter 9 values of psychological scales is connected to the inputs of the adder 15. fla other inputs of the adder 15 from the ROM 10 read the maximum standard value of the same pin, and the ROM 10 these values are stored with a 10 minus sign. If the value of a certain scale for a given test subject is greater than the maximum standard value of the same scale, then at the output of the adder

15 has a positive number. AT

15 otherwise, the output of sum | 15 is a number less than or equal to zero. If the output of the adder 15 gives a positive number, then the key 16 opens from the output of the counter 13 to

20 indicator 17 is given the number of this (this means that according to this psychological characteristic, the subject has significant features that distinguish him from the

25 groups of people). In the OTHER case, the key 16 is closed and the indicator 1 7 shows zeros.

The scale number (difference from zero) displayed on indicator 17, corresponding to

30 answers the number of recommendations for the self-improvement of a given subject or his possible professional orientation.

The device makes it possible to speed up the processing of the results of psychological studies by automating the calculation of the values of psychological scales and their comparison with the maximum {and normative (threshold) values. The lack of moving parts greatly simplifies the device and its reliability.
