Description

Technical Field

[0001] The present invention relates to a computerized cognitive ability assessment system for children, and also relates to a computerized cognitive ability assessment method for children, belonging to the technical field of cognitive assessment. Background Art

[0002] Cognitive function includes various conscious mental activities of humans in the awake state, such as sensation, perception, memory, thinking, language, imagination and executive ability. The assessment of children's cognitive function usually relies on various scales, which can evaluate different dimensions such as IQ and memory. However, since children's cognitive development is a dynamic and phased process, which is affected by individual factors and the environment, it is extremely important to accurately measure children's cognitive function in research. Scale assessment can be a single test or a multidimensional comprehensive assessment, but these methods are difficult to apply to children.

[0003] The Wechsler Preschool Scale of Intelligence (WPPS I) is one of the most widely used traditional assessment tools for intelligence tests for children aged 3 to 6 years old. The scale was compiled by David Wechsler and has been revised many times to meet the needs of children of different ages. The latest version is WPPS I-IV, released in 2012. Although WPPS I is an effective tool for assessing the intelligence of young children, its test is time-consuming, taking an average of 45 minutes, and requires professionally trained examiners to administer the test. In addition, the compliance problems of young children may lead to inaccurate test results or fail to fully reflect the true ability of the subjects. These factors limit the efficiency of WPPSI in clinical applications, remote assessments, and large-scale studies.

[0004] For children, especially young children, their language comprehension, cognitive ability and operational ability are still in the early stages of development, and there are large individual differences. At present, there is a lack of digital cognitive ability assessment tools specifically for young children on the market. There is also a lack of reliable and effective electronic cognitive assessment tools for young children in clinical practice. Therefore, the development of an electronic cognitive ability assessment system suitable for children aged 3 to 6 is not only necessary for assessing the cognitive ability of young children, but also has important research and clinical value. Such a system can overcome the limitations of traditional assessment methods and provide more efficient and accurate assessment methods. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 A schematic diagram of the structure of a computerized cognitive ability assessment system for children provided by the first embodiment of the present invention;

[0053] Figure 2 A flowchart of a computerized cognitive ability assessment method for children provided in the second embodiment of the present invention. DETAILED DESCRIPTION

[0054] The technical content of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] The embodiment of the present invention is designed and developed an electronic cognitive ability assessment system (hereinafter referred to as the assessment system) for children aged 3 to 6 years old, based on the psychological and behavioral characteristics of children aged 3 to 6 years old, using a computerized test method. The assessment system is adapted and simplified based on the Wechsler Intelligence Scale for Children, and then a localized language assessment for children is added to form a short version of the intelligence test. The assessment system includes five core ability categories: perceptual ability, memory ability, thinking ability, executive function and language ability, and is intended to make up for the lack of standardized, systematic and digital children's intelligence assessment tools in the prior art.

[0056] First embodiment

[0057] like Figure 1 As shown, a computerized cognitive ability assessment system for children provided by an embodiment of the present invention includes a login unit 1, an information collection unit 2, a perception assessment unit 3, a memory assessment unit 4, a thinking assessment unit 5, an executive function assessment unit, a language assessment unit 7 and an output unit 8. Among them, the login unit 1 is used for user registration and system login. The information collection unit 2 is connected to the login unit 1 to obtain the user's personal information and store it in the user database. The five assessment units are all connected to the information collection unit 2, and are respectively preset with different assessment tasks to perform cognitive assessments on the user from five different cognitive function dimensions. The output unit 8 is connected to the five assessment units to output the comprehensive assessment results corresponding to the user based on the preset algorithm according to the assessment results of the user's five different cognitive functions.

[0058] Below, each functional unit of the computerized cognitive ability assessment system is described in detail:

[0059] 1. Login Unit

[0060] In this embodiment, the login unit 1 is used for user registration and system login. If the user is a new user, the user needs to register on the registration interface, and after completing the user registration, the system can be logged in through the login unit 1.

[0061] 2. Information Collection Unit

[0062] In this embodiment, when the user logs into the system, he / she will enter the information collection unit 2 and enter personal information (which can be completed by the parents). The personal information includes at least: gender, age, date of birth, years of education, etc.

[0063] When the user completes entering the information, the system will generate a user profile unique to the user and store the user information in the user database.

[0064] 3. Perception Assessment Unit

[0065] In this embodiment, the perceptual evaluation unit 3 is connected to the information collection unit 2 and is preset with a first evaluation task, so as to perform human-computer interaction with the user based on the first evaluation task and obtain first evaluation data for evaluating the user's perceptual ability.

[0066] Specifically, the first evaluation task is configured as follows:

[0067] The first step is to select a plurality of shapes (in this embodiment, triangles, squares and circles, but not limited to these shapes) and correspond them to a plurality of targets (for example, small animals) one by one to form a shape-target mapping table;

[0068] In the second step, multiple target objects are presented to the user in sequence, so as to require the user to select a corresponding shape based on the target objects appearing in the picture.

[0069] It is understandable that in the first assessment task, the user does not know the mapping relationship between the shape and the target object, so it is necessary to match the shape with the target object according to one's own understanding, so as to examine the user's processing speed, that is, the speed of receiving, understanding, and responding to information. During the specific test, different small animals will appear in the screen in turn, and the user needs to quickly find the small house corresponding to the target animal (the shape of each house is one of the above multiple shapes), and click the correct small house button to make the small animal enter the small house.

[0070] In this embodiment, the test duration of the first evaluation task is 3 to 4 minutes. During the evaluation process, it is necessary to record the user's answer results, accuracy, reaction time and other interactive information as the first evaluation data.

[0071] 4. Memory Assessment Unit

[0072] In this embodiment, the memory evaluation unit 4 is connected to the information collection unit 2 and is preset with a second evaluation task, so as to perform human-computer interaction with the user based on the second evaluation task and obtain second evaluation data for evaluating the user's memory ability.

[0073] Specifically, the second evaluation task is configured as follows:

[0074] In the first step, n groups of items are presented to the user in advance, each of which consists of two different items.

[0075] In the second step, one item in any item group is presented to the user in turn, so as to require the user to select another item in the item group.

[0076] It is understandable that in the second assessment task, the user is required to memorize n groups of items first, so as to associate the different information in each group of items for memorization. In the specific test, each time an item in an item group is presented to the user, the user is made to associate it with another item, thereby assessing the user's associative memory ability.

[0077] In this embodiment, the test duration of the second evaluation task is 3 to 4 minutes. During the evaluation process, it is necessary to record the user's answer results, accuracy, reaction time and other interactive information as the second evaluation data.

[0078] 5. Thinking Assessment Unit

[0079] In this embodiment, the thinking assessment unit 5 is connected to the information collection unit 2 and is preset with a third assessment task, so as to perform human-computer interaction with the user based on the third assessment task and obtain third assessment data for assessing the user's thinking ability.

[0080] Specifically, the third evaluation task is configured as follows:

[0081] In the first step, a group of graphics is presented to the user, wherein the group of graphics conforms to a preset rule;

[0082] In the second step, a plurality of graphics to be selected are presented to the user, so as to require the user to select a graphic to be selected that meets a preset rule.

[0083] It is understandable that in the third assessment task, users are required to find the rules that the graphics in a set of graphics (for example: a set of colored squares) conform to, and select the correct graphic option that conforms to the rule, so as to evaluate the user's fluid reasoning ability. Among them, fluid reasoning ability refers to the ability to understand, reason and solve new problems, which involves logical thinking, problem solving, abstract reasoning and information processing speed.

[0084] In this embodiment, the test duration of the third evaluation task is 3 to 4 minutes. During the evaluation process, it is necessary to record the user's answer results, accuracy, reaction time and other interactive information as the third evaluation data.

[0085] VI. Executive Function Assessment Unit

[0086] In this embodiment, the executive function evaluation unit 6 is connected to the information collection unit 2 and is preset with a fourth evaluation task, so as to perform human-computer interaction with the user based on the fourth evaluation task and obtain fourth evaluation data for evaluating the user's executive function.

[0087] Specifically, the fourth evaluation task is configured as follows:

[0088] The first step is to present a preset image to the user for a preset duration.

[0089] In the second step, a group of pictures including preset pictures are presented to the user again to require the user to select the preset pictures therefrom.

[0090] It is understandable that in the fourth assessment task, the user needs to remember the presented picture within the specified time, and immediately operate and recognize the new picture information after it appears, so as to test the user's visual working memory ability. Since working memory is a secondary brain ability under executive function (primary brain ability), the user's executive function level can be effectively reflected by assessing the user's visual working memory ability.

[0091] In this embodiment, the test duration of the fourth evaluation task is 3 to 4 minutes. During the evaluation process, it is necessary to record the user's answer results, accuracy, reaction time and other interactive information as the fourth evaluation data.

[0092] VII. Language Assessment Unit

[0093] In this embodiment, the language assessment unit 7 is connected to the information collection unit 2 and is preset with a fifth assessment task, so as to perform human-computer interaction with the user based on the fifth assessment task and obtain fifth assessment data for assessing the user's language ability.

[0094] Specifically, in this embodiment, the fifth assessment task includes a receptive assessment task and an expressive assessment task, and the configuration of the two tasks is as follows:

[0095] (1) The receptive assessment task configuration is:

[0096] The first step is to show m item images to the user;

[0097] The second step is to play the content of one of the item pictures by voice;

[0098] The third step requires users to select the corresponding item picture based on the played voice.

[0099] (2) The expressiveness assessment task configuration is:

[0100] In the first step, an object map is presented to the user; wherein the object map is selected based on the order and word frequency of the child's spoken language;

[0101] The second step is to ask the user to name the item image.

[0102] It is understandable that in the fifth assessment task, the user is assessed through two different types of assessment tasks (both tasks are assessed), thereby assessing the user's language development level from different aspects to improve the accuracy and effectiveness of the assessment.

[0103] In this embodiment, the test duration of the fifth evaluation task is 3 to 4 minutes. During the evaluation process, it is necessary to record the user's answer results, accuracy, reaction time and other interactive information as the fourth evaluation data.

[0104] In addition, it is understandable that since the test time for each evaluation unit is 3 to 4 minutes, the five evaluation units can be completed in only 15 to 20 minutes, which effectively improves the evaluation efficiency.

[0105] 8. Output Unit

[0106] In this embodiment, the output unit 8 is connected to the perception assessment unit 3, the memory assessment unit 4, the thinking assessment unit 5, the executive function assessment unit 6 and the language assessment unit 7 to obtain the first assessment data, the second assessment data, the third assessment data, the fourth assessment data and the fifth assessment data, and output the user's comprehensive assessment results based on a preset algorithm.

[0107] Specifically, in this embodiment, the preset algorithm includes the following steps:

[0108] ① Standardize each assessment data according to the norm score to obtain the norm score of each assessment. n , n∈(1,5).

[0109] ② According to the normative standard score z corresponding to each evaluation data n , output the cognitive ability evaluation result corresponding to the evaluation data. Among them, in each evaluation data, different score ranges correspond to different cognitive ability evaluation results.

[0110] ③ Based on the evaluation results of the user's five cognitive abilities, jointly output the user's comprehensive evaluation results.

[0111] In addition, in the first embodiment, preferably, the output unit 8 is connected to the information collection unit 2 to store the comprehensive evaluation results of the user in the user database. Thus, the comprehensive evaluation results of the user can be stored each time to facilitate the user to view his or her own stage changes.

[0112] Second embodiment

[0113] like Figure 2 As shown, based on the above first embodiment, the second embodiment of the present invention provides a computerized cognitive ability assessment method for children, which specifically includes steps S1 to S8:

[0114] S1: Obtain user’s personal information.

[0115] Specifically, when a user logs into the system, the system obtains the user's personal information such as gender, age, date of birth, years of education, etc., so as to form a user profile unique to the user, and stores the user information in the user database.

[0116] S2: Evaluate the user's perceptual ability.

[0117] Specifically, after obtaining the user's personal information, the first evaluation task is pushed to the user through the perception evaluation unit 3, so as to perform human-computer interaction with the user based on the first evaluation task and obtain first evaluation data for evaluating the user's perception ability.

[0118] Among them, the configuration process of the first evaluation task and the specific evaluation process refer to the description of the perceptual evaluation unit 3 in the first embodiment, and will not be repeated here.

[0119] S3: Evaluate the user's memory ability.

[0120] Specifically, the second evaluation task is pushed to the user through the memory evaluation unit 4, so as to perform human-computer interaction with the user based on the second evaluation task, and obtain second evaluation data for evaluating the user's memory ability.

[0121] Among them, the configuration process and specific evaluation process of the second evaluation task refer to the description of the memory evaluation unit 4 in the first embodiment, and will not be repeated here.

[0122] S4: Evaluate the user's thinking ability.

[0123] Specifically, the third assessment task is pushed to the user through the thinking assessment unit 5, so as to perform human-computer interaction with the user based on the third assessment task, and obtain third assessment data for assessing the user's thinking ability.

[0124] Among them, the configuration process and specific evaluation process of the third evaluation task refer to the description of the thinking evaluation unit 5 in the first embodiment, and will not be repeated here.

[0125] S5: Evaluate the user's executive function.

[0126] Specifically, the fourth evaluation task is pushed to the user through the execution function evaluation unit 6, so as to perform human-computer interaction with the user based on the fourth evaluation task, and obtain fourth evaluation data for evaluating the user's execution function.

[0127] Among them, the configuration process and specific evaluation process of the fourth evaluation task refer to the description of the execution function evaluation unit 6 in the first embodiment, and will not be repeated here.

[0128] S6: Evaluate the user's language ability.

[0129] Specifically, the fifth assessment task is pushed to the user through the language assessment unit 7, so as to perform human-computer interaction with the user based on the fifth assessment task, and obtain fifth assessment data for assessing the user's language ability.

[0130] The configuration process and specific evaluation process of the fifth evaluation task refer to the description of the language evaluation unit 7 in the first embodiment, which will not be repeated here.

[0131] It is understandable that there is no particular order in which the above steps S2 to S6 occur, but different task-based assessments are performed for different cognitive function dimensions.

[0132] S7: Output the user's comprehensive evaluation results.

[0133] Specifically, after completing the evaluation of the user's five cognitive functions based on steps S2 to S6, a comprehensive evaluation result of the user is output based on a preset algorithm according to the first evaluation data, the second evaluation data, the third evaluation data, the fourth evaluation data and the fifth evaluation data.

[0134] The specific calculation process of the preset algorithm refers to the description of the output unit 8 in the first embodiment, which will not be repeated here.
