Description

{System and Method for Memory Tests}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory test system and method, and more particularly, to a system and method capable of performing a computerized test and providing an analysis based on a normality of test results.

Memory is divided into short-term memory and long-term memory, which are again divided into verbal memory and spatio-temporal memory (nonverbal memory). The memory process consists of inputting, storing, and retrieving information. In order to efficiently process information at each stage, appropriate attention is required. Attention involves the ability to maintain long periods of concentration to perform a given goal, to differentiate between specific stimuli of various stimuli, or to appropriately allocate limited treatment capacity. In addition, during the information processing process, it is important to memorize and maintain the input information. Work memory is a concept that refers to the ability to solve problems by integrating and organizing linguistic or temporal information.

Because the memory function, especially the memory and learning of numbers, languages, and figures, is a cognitive function closely related to the daily life skills, memory impairment is not only a symptom of dementia or brain damage but also a psychiatric disorder such as depression or anxiety, It can be a cognitive symptom. Regular diagnostic evaluation, treatment, and prognostic evaluation of various memory functions are of great interest not only in psychiatric aspects but also in legal and socioeconomic aspects.

Dementia is a symptom in which the cognitive functions of various areas such as memory, language, and judgment are deteriorated and do not perform daily life properly. Starting from amenorrhea in the early stages of dementia, the symptoms gradually worsen as the cognitive functions of various areas such as language, directional sense, and computation power are sequentially degraded. As the personality and emotions change, the possibility of experiencing emotional disturbances such as depression increases, resulting in an increased burden on the caregiver and a deterioration of the overall quality of life. Because of the nature of these disorders, it is important to detect symptoms and intervene in the early stages of cognitive decline, even if they are not yet dementia, in order to prevent dementia. In particular, in the elderly and dementia patients, subjective memory problems are likely to fail to adequately reflect the level of objective memory decline due to lack of knowledge and cognitive decline in cognitive decline, so that for successful prevention and rehabilitation, It is essential to assess the level of memory loss that is accurate and objective.

Korean Laid-Open Patent Application No. 2012-0107736 discloses a system-based computerized cognitive capability measurement and evaluation system and method, and discloses a configuration including a test preparation unit, a cognitive ability measurement unit, a cognitive ability evaluation unit, and a database management unit. The system provides normative data to determine the level of cognitive abilities of the testee as a result of cognitive abilities measurement and evaluation, and eliminates the environmental impact of cognitive abilities measurement using a test preparation unit that includes an interface standardization module. However, the above method does not test the working memory for holding and manipulating the input information, and the apparatus for cognitive domain perception is simply arranged in parallel to determine whether the memory degradation is a problem of the actual storage ability itself or a problem of learning ability or attention There is a disadvantage that it can not be evaluated. Therefore, there is a need for a computer or online based memory assessment tool that can evaluate all elements of memory.

In order to solve the above problems, the present inventors have completed the present invention through the following means. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Prior to the detailed description of the present invention, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It should be understood that various equivalents and modifications may be present.

One. Memory assessment tool

The memory assessment tools are largely classified into four categories: 1) Attention Assessment Task 2) Auditory-Verbal Memory Task 3) Visuo-spatial Memory Task 4) Working Memory Task. 5) Execution function (Executive function). The total time required for the evaluation is 30 to 40 minutes. When the test data of the subject is inputted, the converted score is calculated by the average and standard deviation of the same age range, and an automated interpretation of the range corresponding to the converted score is provided (FIG. 1).

(1) Attention test task

Targeted stimuli and non-target stimuli are randomly presented for 100ms on the screen of the subject's terminal and reacted to the target stimuli as quickly and accurately as possible. In one embodiment of the present invention, the CPT-AX type, which is more or less difficult than the simple CPT, is applied. The test takes about 5 minutes.

(2) Auditory-language memory Auditory - Verbal memory ) Inspection task

On the screen of the testee's terminal, 15 middle-aged and 15 older age-old words were presented three times repeatedly, and immediately recalled, followed by 15-minute delayed long-term delayed recall, ) Inspection.

(3) visual-spatial memory Visuo - spatial memory ) Inspection task

Line, and graphic shapes on a screen of the terminal of the subject simultaneously, and repeating the same test to retrieve and memorize the position and shape of the presented stimulus three times. A long-term delayed recognition test is performed after 15 minutes.

(4) Working memory Working memory ) Inspection task

A working memory test is performed during the 15 - minute retention interval between immediate recall and long - delay recall of auditory - language memory tests and between immediate recall of visual - spatial memory tests and long - term delay. Immediate recall of auditory-language memory, visual-spatial memory After the task is finished, work memory is proceeded. Working memory does not affect stored memory through the practice because the stimuli used in working memory do not have any specific linguistic / visual meaning. For example, in spatio-temporal working memory, bulbs are presented as stimuli, so they do not affect visual memory, which is an abstract figure. In verbal working memory, a single letter such as' It does not affect word stimulation. The contents of each task are as follows.

(4-1) Nonverbal Work Memory Test: The test is performed through the terminal of the subject, such as forwarding according to a spatial span and backward testing according to a reverse span.

(4-2) Verbal task memory test: Letter-Number Sequencing task is performed through the terminal of the subject.

(5) Execution function ( Executive function )

Through the terminal of the examinee, the first task, which is a task to sequentially follow the numbers from 1 to 23, the numbers from 1 to 12, and the letters from 'Donghae water and Baekdusan to Margo' alternately (1- We carry out the task to put it together. The final score reflects only the number A task with numbers and the time of the B task with numbers and letters. Compared with the time spent in the normative group, the faster the performance is completed, the better the performance.

In one embodiment of the present invention, a memory index that reflects the memory score of the auditory-language memory test and the visual-spatial memory test is provided as a result in consideration of the results of the above-mentioned attention test, working memory test and executive function test. The information examination and the stimulation for the examination are controlled to be presented through the terminal of the subject at the memory evaluation server. The server evaluates the memory level of the subject based on the database as the norm.

2. Regulation data preparation process

The normative data used in the memory test method according to an embodiment of the present invention is used as an index for analyzing the test results of the subject and is prepared through the following process. The above-mentioned normative data is used in the form of a database, and new data can be added and accumulated each time a memory test is performed.

First, the age group (40-74 years old) that is the target of memory evaluation is divided into groups according to sex, age, and academic background. The elderly are divided into the elderly in the age group of 60 and over, and the elderly in the elderly in the age group of 60 to 74 years. In the case where the division of education is added, the division of academic ability is excluded, and the elderly can divide into three sections from below junior college level to college graduate level, and the elderly class can be divided into four sections from below junior college level to college graduate level.

For each of the above-mentioned groups, a proportionally calculated number of people will be allocated to the total number of people according to the national distribution of education. In the process of screening the subjects, if there is a history of psychiatric or neurological disease that affects memory, or if the score of the SMMSE-DS is less than the cut-off score, People with abnormal symptoms are excluded.

We perform the memory evaluation tool for the selected subjects and obtain the result value. After calculating the average and standard deviation for the result value, the standardized conversion score or T score is calculated. The calculated score corresponds to one of the four levels of excellent, normal, suspicion, and depression based on the distribution within the group. [Normal] level when the score is included between -1SD and + 1SD on the distribution, [Excellent] level when the score is above + 1SD, [Suspicious] if it is below -1SD, and [Decrease] when it is below -2SD. For example, if a 50-year-old high school graduate has an average score of 10 and a standard deviation of 3, he or she will receive a score of 11 on the language memory task using the converted score.

Based on the normative data provided by the above process, corresponding levels are provided for each measurement area within each test (eg, linguistic working memory and visual working memory in working memory), and an automated interpretation / RTI >

3. Assessment Methods

2 is a flowchart showing a memory test method according to an embodiment of the present invention.

Inspection shall be carried out in a quiet room where the noise is blocked, and one person and one inspector shall be present in the examination room. The subject will proceed alone using the touch screen according to the instructions of the program that is being automatically executed. The examiner assists the patient in verbal memory tests and stays until the end of the test in case the subject complains of fatigue or has other problems. The test stimulus of the memory test method according to the present embodiment is presented audiovisually. The subject listens to auditory stimulation and directive with a headset, and sees visual stimuli and directive of characters, figures and the like through a monitor having a touch screen function. The subject can be informed of the response to the test stimulus verbally and can input the stimulus on the monitor by touching or pressing a button. For example, the verbal memory test may utilize verbal reporting, the visual memory test may cause a stimulus on the monitor to be touched, and the attention test may employ an input method of touching a button on the monitor or a separate button.

First, when the program is executed, the information such as the age, sex, and education level of the subject is registered on the first screen. When the subject enters his / her date of birth, the age is automatically calculated and automatically selected as a middle-aged or old-age test. The elderly can be classified as middle-aged people between the ages of 40 and 60 and those aged between 60 and 74 as the elderly.

Register the subject information and select the type of examination. By default, it is set to Full Scan. If you select the full scan, a message will be displayed for the scan. Press the start scan button to start the scan. The test is [immediate recall of auditory-language memory → immediate recognition of visual-spatial memory → attention test → auditory-language task memory test → visual-spatial task memory test → long-term delayed recall and / or re- ], And the above sequence can not be arbitrarily changed. This can be done by performing the recall or recall task immediately in the tests of the language memory test and the visual memory test, and performing the above-mentioned attention test, auditory-language working memory test, and visual-spatial working memory To minimize the wait time of the testee and to give another time interval between the instant recall and the long delayed recall and / or re-examination, and to perform other tasks that do not cause interference so that repetitive demonstrations can not be performed. The long-term delayed test includes auditory-language memory test and visual-spatial memory test, and long-term delayed recall test is performed immediately before the long-term delay test of auditory-language memory.

3-1. Auditory-Language Memory Test

The auditory - language memory test is a test that measures the memory ability of a subject 's verbal stimulus by allowing the subject to memorize as many words as possible after presenting a series of words audibly. Immediately after using the same test stimuli, the recall task is continued three times in total, and the visual memory test, the attention test, and the work memory test are completed. Long-term delayed inspections are performed once each. In one embodiment of the present invention, attention test and work memory test are performed at the delay time to improve the test convenience of the testee.

Immediate recall of speech-language memory tests The stimuli presented in the task are words of two or three letters and can be selected from the categories of animals, vegetables and transportation. The target stimuli of the middle-aged test are total 15, and may include five words per category. Such as wolves, buttercups, and submarines. The target stimuli of the elderly test are excluded in the same stimulus as the middle-aged test, one word for each category, totaling 12, including 4 words per category. The word stimulus of this test is selected so that it does not overlap with any stimuli used in conventional language memory tests. The high frequency, middle frequency, and low frequency words were included in each category so that the ratio was 2: 2: 1, and the stimulation was presented in a predetermined order.

The non - target stimulus presented in the long - term delay test of the auditory - memory memory test consisted of words that were in the same category as the target stimulus and words not related to the category. The non-target stimulus was set to be similar to the number of letters and frequency of the target stimulus. The total number of stimuli presented in the middle-aged test was 56 (8X7), which is composed of 15 target words, 20 target words in the same category as the target stimuli (eg elephant, wormwood, truck) Target words' (eg, clock, chopsticks, paint). The total number of stimuli presented in the aged test is 49 (7X7), which is 12 target words, 18 target words in the same category as the target stimulus, and 19 random non - target words. The non-target words of the aged test were excluded from the same non-target stimuli as the middle-aged test and two from the same category non-target word and the random non-target word, respectively. The stimuli are arranged according to a predetermined arrangement. The auditory - language memory test consists of 3 repetitions immediately, 1 long - delayed recall, and 1 long - term delay test. In the speech memory test, a fixation point appears on the subject's screen immediately in the recall task. In an embodiment of the present invention, 15 words are displayed in the middle-aged test and 12 words are displayed in the second-grade test in an interval of 2 seconds . If all the stimuli are presented and the same directive as in Figure 3 is given, the subject will report all the words to the examiner. The examinee listens to the words he / she reports and reports the reactions, reactions, and reactions to the checklist presented on the inspector's monitor. The same procedure is carried out three times in total, and one time each of the long-term delay test and the long-term delay test is performed after the visual-spatial memory test, the attention test, and the work memory test. In the long-term delayed recall task, the subject freely recalls all words that are remembered to the tester, and the tester records the regular reaction, the repulsive reaction, and the erroneous response in the checklist presented on the tester monitor. Next, in the task of long-term delay, the subject selects a target word from among several words displayed on the monitor (FIG. 4). The above method is the same for the middle-aged and older aged people.

The scores of the auditory-linguistic memory test were the instantaneous recall task, the number of correctly selected words in the long-delayed task, and the total number of positive responses reported in three recall tasks, Long-delayed recall task, and long-delayed task. This is calculated by the conversion score (average = 10, standard deviation = 3) appropriate for the norm group.

Conversion score =

3-2. Visual-spatial memory test

In one embodiment of the present invention, the visual-spatial memory test presents six (2 × 3) abstract figures on the screen for 10 seconds and measures how accurately the examinee can remember the shape and position of the figure. Immediate re-examination is carried out continuously for a total of 3 times using the same test stimuli, and once a long-term delay test is performed after the attention test and work memory test are completed (after 15 minutes delay).

In an embodiment of the present invention, the test stimuli for visual-spatial memory test are classified into a consonant and a vowel shape (a, c, k, o, g, (A), (b), and (c). In addition, the test method is the same for both middle-aged and elderly, and only the test stimulus is presented differently for difficulty adjustment. As the amount of information to be remembered in the visual-spatial memory test is proportional to the difficulty of the test, the degree of difficulty of the task is increased by adding the number of stimuli to the test for the elderly (FIG.

The inspection process is as follows. First of all, the screening method is introduced on the screen, and a practice test is carried out using a simple four-figure (2 × 2). The following 6 (2 × 3) abstract figures are presented for 10 seconds to instruct the examinee to remember the figure. After the stimulus has disappeared, there are 6 spaces (2 × 3) on the left of the screen and 36 (6 × 6) views on the right. For each of the six stimulus shapes, 36 views (6 correct answers and 5 incorrect answers) are shown, and the same category of figures are presented in each row. (Fig. 7). The examinee selects and touches the correct view among the presented view drawings, touches the appropriate position in the left blank space to select the figure, and leaves the figure in place even after the figure is selected so that the duplicate selection is possible. When you want to change the selected figure, you touch another figure in the view and touch the position you want to change to change the figure. When the six figures are filled in the left margin, the 'Complete' button at the bottom of the screen is flickering, and the subject is activated. Immediate reintroduction 2 and 3 implementation are also the same, and the arrangement of the proposed figure should be presented differently.

In one embodiment of the present invention, after the completion of immediate reinspection 3, an attention test and a work memory test are performed and a long-term delay test is performed after a period of 15 minutes or more has elapsed. The target stimulus is not presented in the long term delayed person, and the correct answer is selected by presenting 6 blank squares (2 × 3) on the left and 36 (6 × 6) view figures on the right side.

The origin score of the visual-spatial memory test is 1 point when the correct shape is selected for each figure, and 1 point when it is placed at the correct position so that the maximum score of each figure is calculated as 2 points. Therefore, the score range of each trial is [0 to 12 points], and the total score range of immediate scores is set to [0 to 36 points]. The score range is set to [0 to 12 points] even in the case of long term delay tolerance. If the same figure is selected in duplicate, it is treated as a speed error and is not included in the origin. Immediately after 1 to 3 times, the number of relaunch points and the number of origin points, which are long-term retarders, are converted into standardized conversion scores (mean = 10, standard deviation = 3) using mean and standard deviation for each age group.

Conversion score =

In one embodiment of the present invention, the Memory Quotient (MQ) is calculated by multiplying the converted score of the auditory-language memory (immediately recalled 3 times, long-term delayed recall, Time, and long-term retardation) to calculate the average value = 100 and the standard deviation = 15. The memory index calculation formula is as follows.

M = (Hearing-Language Memory Immediate Recall Three-Time Total Recall Score + Auditory-Language Memory Long-term Delay Reconciliation Score + Auditory-Language Memory Long-term Delay Reconciliation Score + Visual- + Visual-spatial memory long-term delayed conversion score) / 5

Memory index (MQ) = 100 + 15 ( X M i-10) / 3

The interpretation of the values is automated and presented according to the level combinations based on MQ, linguistic memory, and the converted scores of visual memory.

3-3. Attention check

In one embodiment of the present invention, it is further contemplated to determine whether the memory assessment result is due to a decline in memory or to a lack of attention, wherein the immediate and long-term delayed recall of the auditory- Between immediate and long-term delay, a test to measure continuous attention is presented in a random order, one at a time, for each of the five consecutive A-to-H consonants on the screen. Whenever presented, press the button quickly to react.

In one embodiment of the present invention, Hangul consonants A to H are displayed in a random order on the screen to check attention. The stimulation exposure time is 200ms, and the whole test is divided into 5 intervals, and the interval between the stimuli varies in the order of 1000ms-2000ms-3000ms-2000ms-1000ms depending on the interval. Also, the number of total stimuli is 30 per target area including 6 target stimuli, and the target stimulus ratio is set to be maintained at 20%. Non-target stimuli are presented wirelessly to the extent that they do not overlap with the combination of target stimuli.

In one embodiment of the present invention, an inspection method is introduced on a screen by a method of performing an inspection, and a practice test is performed for 30 seconds so that the target stimulus is two. After the practice test, the results are presented so that you can check your performance, so you can choose to re-practice or go to practice (Figure 8). At the time of the examination, a gaze point is presented on the screen so that the examinee fixes the gaze, and after five seconds of preparation time, the Korean consonants are presented in a wireless order for five minutes from A to H. The test taker should press the button quickly if the c appears consecutively after the stimulus.

The score of the attention test was measured by [missed error], which is the number of times that did not respond to the target stimulus, [number of false alarms], which was the number of responses to the non-target stimulus, And the standard deviation of the reaction time required to respond to the stimulus [standard reaction time standard deviation]. The origin scores of the four variables are converted into T-scores using the mean and standard deviation of each age group. The formula for calculating the T-score is as follows.

T score =

The Attention Quotient (AQ) is calculated by summing the T-scores of the missing error, the false alarm error, the normal reaction time average, and the normal reaction time standard deviation. The attention index (AQ) is [average = 100, standard deviation = 15]. The formula for calculating Attention Index (AQ) is as follows.

A = (T score of missing error + T score of false alarm error + T score of normal reaction time average + T score of standard reaction time standard deviation) / 4

Attention index (AQ) = 100 + 15 (50-X _A i) / 10

The interpretation of the values is automatically presented according to the level combinations based on the missing errors, false alarm errors, the normalized reaction time average, and the converted score of the standard reaction time standard deviation.

3-4. Work memory test

Task memory test tasks consist of auditory - language task memory task and visual - space task memory task. Hearing - language task memory task is a task to show the mixture of Hangul and numbers and rearrange them according to the rules. The visual - space task memory task memorizes the sequence of lighting the 9 (3 × 3) It is a task to reproduce it either in a line or in a retrograde manner. The task of auditory-language task memory consists of irrelevant contents of the auditory-language memory task, so that even if it is executed between the instant recall and the long-delayed recall of the auditory-language memory task, . In addition, the visual-spatial task memory task is composed of contents independent of the visual-spatial memory task, so that even if the visual-spatial memory task is performed between the immediate task recognition and the long-term delay task, As shown in FIG.

3-4-1. Hearing - Language Work Memory

Auditory - Language This is a test stimulus for examining the working memory. It presents verbal stimuli from 3 digits to 8 digits, which is a combination of Hangul from 'Ha-Ha' to the numbers 1-9 through audio. As in "Cha-2-Ga", Hangul and numbers are presented in a mixed order, and "Phrase" and "4" with the same pronunciation are not included in the stimulus. The stimuli are kept unified using the same voice recordings, and the interval between stimuli is maintained at 1000 ms.

First, the instruction is presented on the screen, and then two exercises are performed. After the stimulus presentation is completed, the number of Korean letters to 'KA-HA', the number up to '1-9', the number of stimuli presented A blank space is presented (FIG. 9). The subject memorizes stimuli presented through audio, and rearranges the order in the head. First, the numbers are arranged from small numbers to large numbers, and then the Hangul characters are arranged in alphabetical order. For example, if "car-2-a" is presented as a stimulus, the respondent should arrange the stimulus in the order of "2-a-car". After the presentation of the stimulus is completed through audio, the letters on the uppermost line are displayed on the screen and the numbers from 1 to 9 below the letters are listed on the screen. At the bottom of the list, a blank is displayed in the form of the number of stimuli presented, so that stimuli touched by the examinee are automatically input into the empty space.

In one embodiment of the present invention, the task consists of a total of six items, each of which consists of three trials. In the first question, three combination stimuli are presented, and then one stimulus is added to the next question. When the testee's response is completed, the next test is automatically performed. If all the tests are completed, or if all three tests in one item are incorrect, the test is automatically transferred to the next test.

3-4-2. Visual-space working memory

In an embodiment of the present invention, nine (3x3) bulb pictures are presented on the screen and the bulbs are lit in sequence. The fire comes in for 500 ms and the interval between stimuli is kept at 1000 ms. After the problem screen is presented, a response screen is displayed in which all the lights are turned off so that the examinee can touch the screen bulb in order.

In the visual-space working memory test method, a separate exercise test is not performed after the directive is presented, and the test method will be described through an example screen. In one embodiment of the present invention, the test consists of a Forward task, which memorizes the order in which the light bulbs are lit, and a Backward task, which must remember the order in which the lights are turned on in reverse order. . In the first Forward task, nine (3 × 3) light bulbs are shown on the screen, and each light bulb is sequentially lit from two to nine light bulbs (Figure 11). After the problem screen is presented, a response screen is displayed in which all the bulbs are off, and the examinee memorizes the order in which the lights are turned on and sequentially touches the bulbs (FIG. 10). The bulb that the examinee touched touches the fire again so that they can check their reaction.

In one embodiment of the present invention, the task is composed of a total of 8 items, each item consisting of two exercises. In the first item, two light bulbs are lit sequentially, and then the next item is added, adding the number of lit light bulbs one by one. If the testee's response is completed or if there is no response for more than 10 seconds, the test will automatically proceed to the next test. If all the items are completed, or if all 2 items in one item are incorrect, the test will be automatically transferred to the Backward test. The Backward task reverses the order in which the light bulbs are lit, and starts with the light bulb at the end and touches the light bulb in the reverse order of the presented stimulus. Other methods of testing are the same, and if you complete all the questions or if all 2 items in one item are wrong, you will be automatically transferred to the next one.

The working memory score is assigned to one point for all the tests, the score range of 0-16 points for auditory-language task memory task, and 0-32 points for visual-spatial task memory task, Add them together to have a range of [0-48 points]. The total points of origin are converted into standardized conversion scores with [average = 10, standard deviation = 3] using the mean and standard deviation of each age group.

The Working Memory Quotient (WMQ) is calculated by summing the conversion scores of the auditory-language working memory task and the visual-spatial working memory task to produce a working memory index (WMQ) such that the average is 100 and the standard deviation is 15 do. The calculation formula for the working memory index (WMQ) is as follows.

WM = (auditory-language task memory conversion score + visual-spatial task memory conversion score) / 2

Working memory (WMQ) = 100 + 15 (X _WM i-10) / 3

The interpretation of the values is automated and presented according to level combinations based on the conversion scores of the auditory-language working memory and the visual-spatial working memory.

3-5. Run function check

The performance test consists of Trail Making Test-A (TMT-A) and Trail Making Test-B (TMT-B) and measures the time required to connect all the stimuli sequentially. The current method has the same method as the TMT test, which is performed through current paper inspection. In one embodiment of the present invention, the executive function test is performed after immediate recall or immediate recall, long-term delay recall, and / or re-examination of the auditory-language memory test and visual-spatial memory test.

In order to avoid redundancy with the TMT task currently used in the embodiment of the present invention as an inspection stimulus for the performance test, the TMT-A test presents numbers 1-23 in a specific arrangement on the screen, and TMT-B In the assignment, the characters of "East Sea Water and Mt. Paekdusa", the first measure of the national anthem, are presented along with the numbers from 1-12.

In an embodiment of the present invention, an example screen for a directive and an inspection method is presented on the screen by the inspection method, and a testee conducts a practice test. After the exercise test is completed, the TMT-A task is carried out. The numbers 1-23 on the screen are presented along a specific arrangement, and the examinee sequentially touches the stimulus in numerical order starting from 1 to 23 (FIG. 12). When a touch is recognized, a short confirmation sound is presented so that the examinee can confirm the touch recognition, and a line connecting the previous stimulus and the selected stimulus automatically appears. If the wrong stimulus is selected, an X-marked line will be displayed with a beep, and the previous stimulus will be activated to select again from the previous stimulus. If you touch all the numbers up to 23 sequentially, the instruction and exercise practice for the TMT-B task will automatically be presented.

In the TMT-B task, the numbers 1-12 and the first measure of the national anthem, "East Sea Water and Mt. Paektu," are presented together according to the specific arrangement (Figure 13). Test takers should touch the numbers and letters alternately starting at 1. For example, you should touch the numbers and letters presented in the same order as "1-D-2-D" and sequentially touch the order of each category. The other inspection methods are kept the same as TMT-A.

The origin score of the execution function task includes the time required for each of TMT-A and TMT-B. The original score is converted into a standardized conversion score with [average = 10, standard deviation = 3] using the mean and standard deviation for each age group. The conversion score calculation formula is as follows. Conversion score =
