Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of behavior measurement and psychological assessment, and particularly relates to an unconscious approach-avoidance tendency tester for measuring the approach or avoidance behavior response of an individual to a specific stimulus at an unconscious level. BACKGROUND

[0002] In the field of human behavior research and psychological assessment, the approach or avoidance response of an individual to external stimuli is an important indicator for revealing potential motivation bias, emotional state and cognitive control level. In particular, the automated approach-avoidance behavior at the unconscious level often reflects the true attitude and potential bias of an individual when not under the control of consciousness.

[0003] Traditional approach-avoidance behavior measurement methods such as the stimulus-response compatibility task (Approach-Avoidance Task, AAT) often use icon symbols in combination with key responses to infer the motivation orientation of an individual, but due to its high abstraction and low ecological validity, it is difficult to accurately capture the behavior pattern in a natural state. Therefore, it is urgent to develop a behavior measurement tool based on real body movements with higher ecological validity.

[0004] Zhou et al. (2012) found through an approach-avoidance task based on push-pull actions that even without explicit instructions, individuals would show systematic approach bias when facing situational images (such as drug-related pictures). This finding not only applies to substance addiction groups, but also suggests that approach-avoidance response can be an important tool for assessing an individual's potential risk behavior, motivation conflict, stress sensitivity, etc.

[0005] However, there is currently a lack of unconscious approach-avoidance behavior testing equipment that can be standardized, automatically recorded, and suitable for multiple groups of people. Existing methods rely on self-made systems or simple laboratory tools, making it difficult to apply to clinical assessment, judicial screening, organizational selection, and behavioral research, etc.

[0006] Therefore, there is an urgent need for a general-purpose, high-ecological-validity, and highly adaptable unconscious approach-avoidance tendency tester to accurately measure an individual's implicit motivation response to a specific stimulus category and improve the objectivity and sensitivity of psychological behavior assessment. SUMMARY

[0043] The present application will be further described and explained with reference to the accompanying drawings and specific embodiments. The technical features of each embodiment of the present application can be combined accordingly without conflict.

[0044] As shown in the figure, it is an unconscious avoidance tendency tester provided by the present application, which can objectively measure the automatic approach or avoidance behavior tendency of individuals when facing specific situation stimuli. The tester mainly includes a special software for presenting visual stimuli and recording reaction data, a computer device for running the software, a push-pull reaction box for performing push (avoidance) or pull (approach) operation and collecting reaction signals, a data exchange module connecting the computer and the reaction device, and a cloud server supporting remote storage and analysis. By recording the reaction time and push-pull speed of individuals under different types of stimuli (such as emotional, addictive, dangerous, etc.), the tester can automatically calculate the unconscious avoidance behavior index, and then assist in judging the potential motivation bias or risk state of individuals. Figure 1 The structure and function of each component will be described in detail below.

[0045] In the device of the present application, the special software for avoidance evaluation is mainly used to automatically present specific situation stimuli and collect the behavior information of individuals on the pull or push operation of different stimuli.

[0046] As a preferred embodiment of the present application, the special software for avoidance evaluation can be divided into several modules working cooperatively in function, specifically including:

[0047]

[0048] ​1) Communication Control Module: This module is responsible for establishing and managing stable communication between the computer device and the push-pull reaction box. In a specific embodiment, the communication can be achieved through a USB interface, with signal conversion through an internal USB-to-TTL serial communication chip. The communication protocol can be set to a baud rate of 115200 to ensure real-time and accuracy of data transmission. After software startup, this module first sends a preset device query instruction (e.g., hexadecimal code "5A00") to the push-pull reaction box to perform device handshake and connection verification. When receiving the valid device number returned by the push-pull reaction box, it confirms that the communication link is successfully established.

[0049] 2) Task Execution and Synchronization Module: This module is the core controller of the test process. It presents specific situational stimuli (such as addiction-related pictures) on the display screen of the computer device according to the preset experimental paradigm. At the precise moment of stimulus presentation, this module sends a synchronization timing start instruction (e.g., hexadecimal code "FB00") to the push-pull reaction box through the communication control module. This instruction ensures that the appearance of visual stimuli and the start of the internal timer of the push-pull reaction box are strictly synchronized in time, providing a basis for accurate measurement of reaction time.

[0050] 3) Data Analysis and Calculation Module: This module is responsible for processing raw behavioral data uploaded from the push-pull reaction box. When an individual makes a push or pull action on the stimulus, the sensor group in the push-pull reaction box captures a series of motion parameters. This module parses the received data packet and extracts key information.

[0051] Specifically, it can accurately distinguish and calculate two core time indicators:

[0052] 31) Psychological Reaction Time (RT): The time elapsed from the start of visual stimulus presentation to the moment the activity handle leaves the initial "zero point" position. This indicator mainly reflects the individual's cognitive processing and decision-making speed.

[0053] 32) Movement Time (MT): The time elapsed from the start of the activity handle movement to its movement to the preset end position (i.e., touching the limiting device inside the box). This indicator mainly reflects the individual's action execution speed and decisiveness.

[0054] At the same time, this module also parses the reaction direction (push or pull) of this operation.

[0055] Through the above settings, the special software for approach-avoidance assessment has the following functions:

[0056] Control the presentation order and content category of situational image or video stimuli;

[0057] The automatic recording of individual operation behaviors on different types of stimuli, including reaction direction (push / pull), reaction time, movement amplitude, etc.

[0058] Based on the behavior data, the avoidance bias index of the individual is calculated to measure the unconscious motivation response characteristics of the individual to the target stimulus.

[0059] In addition, the avoidance evaluation special software has an adaptive adjustment function, which can dynamically adjust the frequency, type or task order of stimulus presentation according to the real-time behavior performance of the tested individual during the test process, so as to improve the sensitivity and measurement accuracy of the behavior response.

[0060] In actual use, the test software (i.e. avoidance evaluation special software) can set multiple types of stimuli (such as emotion-related, risk-inducing, addiction cues, neutral control images, etc.), and automatically pseudo-randomly present them in the central area of the screen to guide the individual to perform a conditioned reflex push-pull operation.

[0061] As a preferred embodiment of the present application, the test software interface includes four modules: "start measurement", "parameter setting", "data viewing" and "system management". The operator can preset the stimulus presentation mode (image / video / pseudo-random order), the reaction time window and the total task duration through the interface, and the system automatically controls the stimulus presentation rhythm and records all behavior responses.

[0062] In the device of the present application, the computer device is mainly used to run the avoidance evaluation special software and record and process the data obtained from the data exchange module.

[0063] As a preferred embodiment of the present application, the computer device mainly includes a display screen, a host, an input device and a camera. Among them, the display screen is mainly used to present the visual stimulus task content of the avoidance evaluation special software; the host is mainly used for the running of the avoidance evaluation special software, data processing and local storage; the input device is mainly used for test task setting and interaction control by the operator; and the camera is mainly used to record the external behavior characteristics of the subject, which can assist in recording unstructured behavior characteristics (such as expression, gaze, posture) for comprehensive analysis of behavior response consistency.

[0064] The test task (i.e. specific situation stimulus) can set multiple stimulus types, including but not limited to:

[0065] Addiction-related stimuli (such as drug images);

[0066] Emotional stimuli (such as angry or fearful faces);

[0067] Neutral control stimuli (such as landscape or living object images);

[0068] The stimulation content can be flexibly changed according to the test purpose, and the image brightness, size and complexity and other parameters are matched.

[0069] In the device of the application, the push-pull reaction box is mainly used for receiving the pulling or pushing operation of the individual, simulating the approach and avoidance behavior by pulling and pushing, and collecting the motion parameters including the displacement direction, amplitude and reaction time.

[0070] As a preferred embodiment of the application, as shown in Figure 2 The push-pull reaction box mainly includes a box structure. Specifically, the box structure is provided with a handle 1 at the top, a horizontal guide rod 4, a limiting device 5 and a sensor group 6 inside; the horizontal guide rod 4 is slidably connected with a movable handle 2 through a sliding block 7, and the other end of the movable handle 2 extends out of the box structure to facilitate the individual to hold; the movable handle 2 is moved along the horizontal guide rod 4 by pushing or pulling to simulate the approach or avoidance behavior; the horizontal guide rod 4 is provided with limiting devices 5 at both ends, and the sensor group 6 is arranged inside the two limiting devices 5; the limiting device 5 is used to prevent over-pushing and improve the durability of the equipment; the sensor group 6 includes a displacement sensor and a speed sensor, which is used to record the direction, speed and distance of the handle movement in real time.

[0071] In actual use, the movable handle 2 is constrained to move along a single axis by the horizontal guide rod 4 and the limiting device 5.

[0072] In actual use, the box structure is made of high-strength aluminum alloy (such as 7075 aluminum alloy) or engineering plastic to ensure stability and safety during repeated testing. In addition, a positioning handle 3 is arranged on the outer wall surface of the box structure for the individual to hold with the other hand (i.e. the hand not doing the pushing and pulling action). That is, during actual testing, the individual holds the movable handle 2 with one hand to do the pushing and pulling action, and holds the positioning handle 3 with the other hand. The design of the two handles should conform to ergonomics to facilitate continuous multiple testing.

[0073] In the device of the application, the data exchange module is mainly used for real-time transmission of the data collected in the push-pull reaction box to the computer equipment.

[0074] In the device of the application, the cloud server is connected with the computer equipment and the push-pull reaction box, and is mainly used for receiving, storing and backing up the data generated during the individual behavior test process, for subsequent behavior evaluation and statistical analysis.

[0075] As a preferred embodiment of the application, the cloud server supports data synchronization with a remote database, encrypted storage and access permission management functions, and can realize the following applications:

[0076] Remote call of individual multiple measurement records supports longitudinal behavior change evaluation;

[0077] Anonymized population data aggregate analysis for scientific research statistics or model training;

[0078] Behavioral bias warning mechanism, automatically sends a flag to the relevant management system when an individual exhibits a significantly abnormal avoidance pattern.

[0079] The tester of the present application can be suitable for multiple target populations, including but not limited to:

[0080] Motivational conflict response research of ordinary individuals in special task situations;

[0081] Substance addicts (such as heroin, methamphetamine, and alcohol addicts);

[0082] Behavioral addicts (such as online game addicts and social media overusers);

[0083] Emotion regulation disorder population (such as anxiety and post-traumatic stress disorder).

[0084] The tester of the present application can be suitable for the following behavioral measurement situations:

[0085] Unconscious approach bias measurement of substance addicts and behavioral addicts;

[0086] Evaluation of potential risk behaviors, avoidance responses, or motivational conflicts of the general population;

[0087] Screening of pre-treatment psychological characteristics or evaluation of rehabilitation effect trend;

[0088] The collected data can be analyzed in conjunction with physiological indicators (such as heart rate, skin electricity, and brain electricity) to improve measurement validity.

[0089] As a preferred embodiment of the present application, the test results obtained by the tester output the "behavioral avoidance bias score" of the individual, which quantifies the unconscious motivational direction of the individual to a certain type of stimulus, and can assist in clinical diagnosis, intervention screening, risk identification, and behavioral science research.

[0090] In the actual test arrangement scene, the subject sits at the table, looks at the display screen with both eyes, and holds the movable handle with the dominant hand. After each stimulus appears, the subject does not need to make logical judgments, but only makes natural pushing or pulling actions based on the first reaction. The entire test process lasts for 10 to 15 minutes, which can be set according to the complexity of the task.

[0091] The system calculates the "behavioral avoidance bias score" through a preset algorithm, which is a function of the reaction time difference of the individual under two types of stimuli (such as target vs. neutral), and is used to measure the approach or avoidance motivation tendency. For example: approach bias = RT neutral - RT target, positive value indicates approach, and negative value indicates avoidance.

[0092] All raw data and calculation results are saved locally and synchronized to the cloud server to support individual evaluation, tracking follow-up and group statistical analysis. The device of the application can be used synchronously with physiological sensors such as heart rate, skin electricity, and electroencephalogram, to enhance the interpretability of behavior data.

[0093] The unconscious avoidance tendency tester provided by the application has the characteristics of automation, non-invasion and standardization, is suitable for application scenes such as addiction screening, anxiety evaluation, impulsive behavior research and mental health evaluation, and can be used as an important auxiliary tool in scientific research, medical treatment, justice and education systems.

[0094] The above-described embodiment is only a preferred scheme of the application, and is not intended to limit the application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the application. Therefore, any technical scheme obtained by equivalent replacement or equivalent transformation falls within the protection scope of the application.
