Abstract
Description
Technical Field
[0001] This application relates to the field of trauma assessment technology, and in particular to a trauma memory intervention method, system, storage medium and product. Background Technology
[0002] Currently, interventions for traumatic memories (including laboratory-induced fear memories) commonly employ traditional psychological intervention methods such as cognitive behavioral therapy or exposure therapy in both clinical and research fields. These methods typically guide subjects to recall or be exposed to traumatic cues based on their subjective experience and attempt to assist them with cognitive guidance tasks through verbal instruction. In recent years, with the development of virtual reality technology and physiological monitoring equipment, some systems have attempted to combine virtual reality exposure therapy with the collection of physiological signals such as heart rate and skin conductance to improve the objectivity and controllability of the intervention. These systems induce emotional responses in individuals by presenting virtual traumatic scenarios, while simultaneously recording physiological indicators to assess arousal levels during the intervention process.
[0003] However, traditional virtual reality exposure therapy cannot automatically adjust the presentation level of traumatic stimuli or the level of cognitive guidance tasks based on the subject's current physiological response during the intervention process, making it difficult to achieve real-time control of the trauma memory intervention process. Summary of the Invention
[0004] The main purpose of this application is to provide a method, system, storage medium and product for trauma memory intervention, which aims to solve the technical problem that it is difficult to achieve real-time control of the trauma memory intervention process in traditional trauma memory intervention programs.
[0005] To achieve the above objectives, this application proposes a method for trauma memory intervention, the method comprising: Subjects were subjected to standard traumatic stimulation to induce target memories, and standard physiological signals generated by the subjects through the standard traumatic stimulation were collected. Within a preset time window after the target memory is induced, the subject is assessed for traumatic stimuli and a cognitive guidance task is performed simultaneously, while the subject's assessment physiological signals are collected in real time. Based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessment traumatic stimulus and / or the cognitive level of the cognitive guidance task are dynamically adjusted.
[0006] In one embodiment, the preset time window includes a memory reconsolidation time window; The step of assessing the traumatic stimulus and simultaneously performing a cognitive guidance task on the subject within a preset time window after the target memory is induced, and collecting the subject's assessment physiological signals in real time, includes: Within the memory reconsolidation time window, the subject is assessed for traumatic stimuli, wherein the assessed traumatic stimuli are correlated with the standard traumatic stimuli, and the assessed traumatic stimuli are used to reactivate the target memory; The subject was guided to re-evaluate the target memory; The assessment physiological signals generated by the subject during the assessment traumatic stimulus and the re-evaluation are collected in real time.
[0007] In one embodiment, the step of guiding the subject to re-evaluate the target memory includes: The subjects were presented with instructions for a cognitive guidance task; After the subject reads the instructions for the cognitive guidance task, the subject is asked to re-evaluate the target memory through an interactive interface.
[0008] In one embodiment, the step of dynamically adjusting the stimulation level of the assessed traumatic stimulus based on the comparison result of the standard physiological signal and the assessed physiological signal includes: The difference between the standard physiological signal and the evaluation physiological signal is compared to obtain the comparison result; When the comparison result is greater than or equal to a first preset threshold, the stimulation level of the assessed traumatic stimulus is reduced. When the comparison result is less than the first preset threshold, the stimulation level of the assessed traumatic stimulus is increased.
[0009] In one embodiment, the step of dynamically adjusting the cognitive level of the cognitive guidance task based on the comparison results of the standard physiological signal and the evaluation physiological signal includes: The difference between the standard physiological signal and the evaluation physiological signal is compared to obtain the comparison result; When the comparison result is greater than or equal to the second preset threshold, the cognitive level of the cognitive guidance task is reduced. When the comparison result is less than the second preset threshold, the cognitive level of the cognitive guidance task is increased.
[0010] In one embodiment, the standard traumatic stimulus includes at least one of a static stimulus image, a stimulus audio clip, or a virtual reality scene.
[0011] In one embodiment, after the step of dynamically adjusting the stimulus level of the assessed traumatic stimulus and / or the cognitive level of the cognitively guided task based on the comparison results of the standard physiological signal and the assessed physiological signal, the method further includes: The subject is subjected to the assessment traumatic stimulus to generate a post-test physiological signal, and the post-test physiological signal is compared with the standard physiological signal to obtain the post-test comparison result; Based on the post-test comparison results, an intervention effect evaluation index is generated; The trauma memory intervention was evaluated on the subjects based on the intervention effect evaluation indicators.
[0012] Furthermore, to achieve the above objectives, this application also proposes a trauma memory intervention system, which includes: The stimulation module is used to apply standard traumatic stimulation to the subject to induce target memory and to collect standard physiological signals generated by the subject through the standard traumatic stimulation. The reassessment module is used to assess the traumatic stimulus on the subject within a preset time window after the target memory is induced, and to perform a cognitive guidance task at the same time, and to collect the subject's assessment physiological signals in real time. The adjustment module is used to dynamically adjust the stimulation level of the assessed traumatic stimulus and / or the cognitive level of the cognitive guidance task based on the comparison results of the standard physiological signal and the assessed physiological signal.
[0013] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the trauma memory intervention method described above.
[0014] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the trauma memory intervention method described above.
[0015] This application applies standard traumatic stimuli to subjects to induce target memories and collects standard physiological signals generated by the subjects through the standard traumatic stimuli. Within a preset time window after the target memory is induced, the subjects are assessed for the traumatic stimuli while simultaneously performing a cognitive guidance task, and the assessment physiological signals of the subjects are collected in real time. Based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessment traumatic stimuli and / or the cognitive level of the cognitive guidance task are dynamically adjusted. That is, the embodiments of this application use standard traumatic stimuli to induce target memories and collect standard physiological signals as an individualized baseline level for subjects, providing an objective self-reference benchmark for subsequent real-time comparisons. Within a preset time window after the target memory is induced, the subjects are assessed for the traumatic stimuli while simultaneously performing a cognitive guidance task, and the assessment physiological signals are collected in real time, achieving temporal synchronization among the presentation of traumatic cues, the execution of cognitive tasks, and physiological monitoring during the intervention process. On this basis, based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessment traumatic stimuli and / or the cognitive level of the cognitive guidance task are dynamically adjusted. Therefore, this application can automatically and accurately adjust the intensity of intervention based on the real-time changes in the subject's current physiological response relative to their baseline, thus achieving dynamic control of the trauma memory intervention process.

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.
[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.
[0022] The main solution of this application embodiment is: to subject the subject to standard traumatic stimulation to induce target memory, and to collect the standard physiological signals generated by the subject through the standard traumatic stimulation; Within a preset time window after the target memory is induced, the subject is assessed for traumatic stimuli and a cognitive guidance task is performed simultaneously, while the subject's assessment physiological signals are collected in real time. Based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessment traumatic stimulus and / or the cognitive level of the cognitive guidance task are dynamically adjusted.
[0023] In this embodiment, for ease of description, the trauma memory intervention system will be used as the implementing entity for the following description.
[0024] Currently, interventions for traumatic memories (including laboratory-induced fear memories) commonly employ traditional psychological intervention methods such as cognitive behavioral therapy or exposure therapy in both clinical and research fields. These methods typically guide subjects to recall or be exposed to traumatic cues based on their subjective experience and attempt to assist them with cognitive guidance tasks through verbal instruction. In recent years, with the development of virtual reality technology and physiological monitoring equipment, some systems have attempted to combine virtual reality exposure therapy with the collection of physiological signals such as heart rate and skin conductance to improve the objectivity and controllability of the intervention. These systems induce emotional responses in individuals by presenting virtual traumatic scenarios, while simultaneously recording physiological indicators to assess arousal levels during the intervention process.
[0025] However, traditional virtual reality exposure therapy cannot automatically adjust the presentation level of traumatic stimuli or the level of cognitive guidance tasks based on the subject's current physiological response during the intervention process, making it difficult to achieve real-time control of the trauma memory intervention process.
[0026] This application provides a solution for subjecting a subject to standard traumatic stimulation to induce a target memory and for collecting standard physiological signals generated by the subject through the standard traumatic stimulation. Within a preset time window after the target memory is induced, the subject is assessed for traumatic stimuli and a cognitive guidance task is performed simultaneously, while the subject's assessment physiological signals are collected in real time. Based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessment traumatic stimulus and / or the cognitive level of the cognitive guidance task are dynamically adjusted.
[0027] This application applies standard traumatic stimuli to subjects to induce target memories and collects standard physiological signals generated by the subjects through the standard traumatic stimuli. Within a preset time window after the target memory is induced, the subjects are assessed for the traumatic stimuli while simultaneously performing a cognitive guidance task, and the assessment physiological signals of the subjects are collected in real time. Based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessment traumatic stimuli and / or the cognitive level of the cognitive guidance task are dynamically adjusted. That is, the embodiments of this application use standard traumatic stimuli to induce target memories and collect standard physiological signals as an individualized baseline level for subjects, providing an objective self-reference benchmark for subsequent real-time comparisons. Within a preset time window after the target memory is induced, the subjects are assessed for the traumatic stimuli while simultaneously performing a cognitive guidance task, and the assessment physiological signals are collected in real time, achieving temporal synchronization among the presentation of traumatic cues, the execution of cognitive tasks, and physiological monitoring during the intervention process. On this basis, based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessment traumatic stimuli and / or the cognitive level of the cognitive guidance task are dynamically adjusted. Therefore, this application can automatically and accurately adjust the intensity of intervention based on the real-time changes in the subject's current physiological response relative to their baseline, thus achieving dynamic control of the trauma memory intervention process.
[0028] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or a trauma memory intervention system capable of achieving the above functions. The following description uses a trauma memory intervention system as an example to illustrate this embodiment and the subsequent embodiments.
[0029] Based on this, the embodiments of this application provide a method for trauma memory intervention, referring to... Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the trauma memory intervention method of this application.
[0030] In this embodiment, the trauma memory intervention method includes steps S10 to S30: Step S10: Apply standard traumatic stimulation to the subject to induce target memory, and collect the standard physiological signals generated by the subject through the standard traumatic stimulation; It should be noted that a standard traumatic stimulus refers to standardized stimulus material that can induce specific traumatic memories or fear responses in a subject. In practical applications, a standard traumatic stimulus can be at least one of the following: a static stimulus image, a stimulus audio clip, or a virtual reality scene. For example, for traumatic memories related to traffic accidents, a picture of a car accident scene can be used as a standard traumatic stimulus. For traumatic memories related to war, an audio clip of an explosion can be used. The standard traumatic stimulus is presented to the subject through a computer-controlled presentation device (such as a monitor, speakers, or virtual reality headset), ensuring that the stimulus content, duration, intensity, and other parameters are completely consistent each time, thereby standardizing the intervention process. Standard physiological signals refer to objective physiological response indicators generated by the subject when receiving a standard traumatic stimulus. Standard physiological signals can include at least one of the following: skin conductance response, heart rate variability, and electroencephalogram (EEG) signals. The standard physiological signal is collected for a preset duration from the start of stimulus presentation to the end of stimulus presentation (e.g., 10 seconds after stimulus presentation), and the peak response value within this period is taken as the standard physiological signal. This standard physiological signal represents the subject's individualized baseline response level to the traumatic stimulus, providing an objective self-reference benchmark for subsequent real-time comparisons.
[0031] Preferably, standard physiological signals of the subject are collected through standard traumatic stimulation, wherein the skin conductance response is obtained by extracting skin conductance level and skin conductance response. Skin conductance level is used to reflect the overall sympathetic arousal tone of the subject, and skin conductance response is used to reflect the immediate arousal response to specific stimuli. When the skin conductance level increases or the frequency and amplitude of the skin conductance response increase, it indicates that the subject's physiological signal level has increased. Standard physiological signals can also be electromyography (EMG), obtained by collecting surface EMG signals of the subject's facial or forearm muscle groups and extracting the root mean square amplitude. Standard physiological signals can also include heart rate, obtained by extracting the subject's instantaneous heart rate and heart rate variability. An increased heart rate and decreased heart rate variability both indicate sympathetic dominance and increased emotional arousal. A stable heart rate and increased heart rate variability indicate good sympathetic regulation and that the subject is in a relatively calm state.
[0032] Understandably, by standardizing stimulus presentation methods, a high degree of consistency in parameters such as stimulus content, duration, and intensity is ensured in each intervention, eliminating temporal errors and content deviations caused by manual operation, thus making the entire intervention process repeatable and comparable. Simultaneously, by collecting standard physiological signals from subjects as an individualized baseline, comparing real-time physiological responses during subsequent interventions with this baseline allows for an objective and quantitative assessment of the subject's real-time emotional arousal relative to their own state, avoiding the limitations of relying solely on group statistical averages or subjective verbal reports. This provides a precise individualized reference benchmark for subsequent real-time comparisons and dynamic adjustments, laying the data foundation for achieving closed-loop feedback control throughout the entire process, and ensuring that the intervention plan can be accurately adapted to the individual differences of different subjects.
[0033] Step S20: Within a preset time window after the target memory is induced, the subject is assessed for traumatic stimuli and a cognitive guidance task is performed simultaneously, and the subject's assessment physiological signals are collected in real time. It should be noted that the preset time window refers to a specific time interval from the initial evoking of the target memory until the memory stabilizes again. According to the theory of memory reconsolidation, after a memory is reactivated, it enters an unstable "reconsolidation" state, which typically lasts from several minutes to several hours. During this period, intervention can effectively alter or block the spontaneous recovery of the memory. The preset time window in this application is preferably a memory reconsolidation time window, i.e., within 1 to 24 hours after the target memory is evoked. In practical applications, the specific duration of this time window can be adjusted according to individual differences of the subjects, the type of trauma, and the experimental design, for example, set to 2 hours, 6 hours, or 12 hours. The assessment traumatic stimulus refers to stimulus material that is correlated with the standard traumatic stimulus, with the aim of reactivating the previously evoked target memory. The assessment physiological signal refers to the physiological response indicators generated in real time by the subject during the assessment of the traumatic stimulus and the execution of the cognitive guidance task. The acquisition method of this signal is the same as that of the standard physiological signal, using the same physiological sensors and acquisition parameters to ensure the comparability of the data before and after. The difference between assessment physiological signals and standard physiological signals lies in the different collection time points. Standard physiological signals reflect the baseline level before intervention, while assessment physiological signals reflect the real-time status during the intervention process.
[0034] Understandably, performing a cognitive guidance task simultaneously refers to presenting the subject with instructions for the cognitive guidance task while evaluating the traumatic stimulus. A cognitive guidance task is an emotion regulation strategy that requires subjects to change their cognitive interpretation of traumatic memories, thereby reducing their negative emotional responses. In practice, the instructions for the cognitive guidance task can be displayed in text form on a monitor or played through an audio device. For example, the instructions could be set as, "Try to re-examine the traumatic scene you just experienced from a more positive and objective perspective." After the subject reads or listens to the instructions, an interactive interface can be used to ask the subject to input their re-evaluated perspective to ensure the quality of the cognitive guidance task.
[0035] In one feasible implementation, the preset time window includes a memory reconsolidation time window; The step of assessing the traumatic stimulus and simultaneously performing a cognitive guidance task on the subject within a preset time window after the target memory is induced, and collecting the subject's assessment physiological signals in real time, includes: Within the memory reconsolidation time window, the subject is assessed for traumatic stimuli, wherein the assessed traumatic stimuli are correlated with the standard traumatic stimuli, and the assessed traumatic stimuli are used to reactivate the target memory; The subject was guided to re-evaluate the target memory; The assessment physiological signals generated by the subject during the assessment traumatic stimulus and the re-evaluation are collected in real time.
[0036] It's important to note that the memory reconsolidation time window refers to the time interval between the reactivation of the target memory and its subsequent stabilization, typically ranging from a few minutes to several hours. The correlation between the assessed traumatic stimulus and the standard traumatic stimulus can be reflected in content similarity (like a picture), semantic relevance (like a similar scene), or consistency in emotional valence. For example, if the standard traumatic stimulus is a picture of a car accident, the assessed traumatic stimulus could be the same picture or a different picture of a car accident from a different angle to ensure accurate reactivation of the previous target memory. Similarly, if the standard traumatic stimulus is a picture of a horrifying face, the assessed traumatic stimulus could be the same picture. If the standard traumatic stimulus is an audio recording of an explosion, the assessed traumatic stimulus could be the same audio recording. The presentation duration of the assessed traumatic stimulus is typically 3 to 10 seconds to ensure effective activation of the target memory. The subject is then guided to re-evaluate the target memory. Specifically, while presenting the assessed traumatic stimulus, cognitive guidance instructions are displayed on a screen, such as: "Try to re-examine the traumatic scene you just experienced from a more positive and objective perspective." After the instructions are presented, the subject is asked to input their re-evaluated viewpoint through a voice or text input interface. For example, the subject could input: "Although this scenario is terrifying, I was not actually harmed." Finally, the physiological signals generated by the subject during the assessment of the traumatic stimulus and the re-evaluation are collected in real time. This collection process covers the entire time period from the start of the assessment of the traumatic stimulus to the end of the cognitively guided task, with a collection frequency typically set to 10 to 100 times per second to ensure that subtle changes in the subject's physiological responses are captured.
[0037] Understandably, by limiting intervention to the memory reconsolidation time window, the intervention ensures that it occurs during the critical period when memories are most unstable and easily modified. Simultaneously, by precisely activating target memories through associative stimuli and conducting cognitive intervention through guided re-evaluation, precise targeted intervention of traumatic memories is achieved. This significantly improves the effectiveness of the intervention and can more effectively block the spontaneous recovery of traumatic memories.
[0038] In one feasible implementation, the step of guiding the subject to re-evaluate the target memory includes: The subjects were presented with instructions for a cognitive guidance task; After the subject reads the instructions for the cognitive guidance task, the subject is asked to re-evaluate the target memory through an interactive interface.
[0039] It's important to note that, firstly, the cognitive guidance task instructions are presented to the participants. These instructions can be displayed as text on a monitor or played via audio. In practice, the instructions can be standardized, such as: "Try to re-examine the traumatic scene you just experienced from a more positive, objective, or safer perspective, and consider whether there are any positive factors or protective information that you previously overlooked." The presentation time for these instructions is typically 5 to 15 seconds, ensuring that participants have sufficient time to understand their content. Secondly, after the participants read the re-evaluation instructions, they are asked to re-evaluate the target memory through an interactive interface. This interface can be a touchscreen, keyboard, or voice input device. For example, the system displays an input box, asking participants to enter their re-evaluated viewpoint in text form, such as, "Although the scene was terrifying, I was not actually harmed." If the participants' re-evaluation still contains significant negative cognitive biases, the system can further present guiding prompts, such as "Try to find details in this scene that are beneficial to you," until the participants generate positive or neutral evaluations that meet preset criteria. In the voice input mode, the system can use speech recognition technology to convert the subject's verbal response into text and perform semantic analysis to determine whether there is a negative cognitive bias.
[0040] Understandably, standardized instructions and interactive mechanisms transform cognitive guidance tasks from abstract theoretical concepts into concrete, executable, and monitorable operational steps. This ensures consistency in the execution of cognitive guidance tasks across different participants, while interactive feedback mechanisms guarantee the quality of task execution, making the cognitive intervention process controllable and quantifiable.
[0041] Step S30: Based on the comparison results of the standard physiological signal and the assessment physiological signal, dynamically adjust the stimulation level of the assessment traumatic stimulus and / or the cognitive level of the cognitive guidance task.
[0042] It should be noted that the comparison result refers to the quantitative index obtained by comparing the real-time acquired assessment physiological signals with the pre-stored standard physiological signals. In practical applications, the system presets multiple levels of stimulus versions, divided into 5 levels from low to high. Specific adjustment methods include: changing the richness of detail and emotional vocabulary density of the trauma narrative (the higher the level, the more detailed the narrative and the stronger the emotional color), adjusting the speech rate and tone intensity of the audio presentation, and adjusting the duration of stimulus presentation. The comparison result can be obtained through difference calculation, ratio calculation, or other statistical methods. For example, the difference can be obtained by subtracting the standard physiological signal value from the assessment physiological signal value, or the ratio can be obtained by dividing the assessment physiological signal value by the standard physiological signal value. This comparison result reflects the subject's emotional arousal level relative to their baseline during the intervention; the larger the comparison result, the stronger the subject's current emotional response. Dynamic adjustment refers to the closed-loop feedback process of adjusting intervention parameters in real time based on changes in the comparison result. Specifically, the stimulus level refers to the intensity of the presentation of the assessment trauma stimulus, which can be quantified in various ways, such as the brightness value of an image, the volume decibel value of audio and video, and the immersion parameters of a virtual reality scene. Cognitive level refers to the difficulty level of the cognitive guidance task, and the system also presets multiple difficulty levels. At low difficulty, the system provides more reassessment prompts and guidance (such as directly offering alternative reassessment approaches for the participant to choose from); at medium difficulty, the system only provides brief prompts or directional guidance, and the participant needs to organize the reassessment content independently; at high difficulty, the system provides no prompts, requiring the participant to generate a reassessment perspective completely independently and express it orally or in writing. This can be quantified in various ways, such as the abstractness of the guidance, the complexity of the interactive task, and the difficulty of the language expression. When the comparison result exceeds a preset threshold, it indicates that the participant's current response is too strong or the cognitive load is too high, and the stimulus level or cognitive level is automatically reduced. When the comparison result is below the preset threshold, it indicates that the participant's current response is stable or the cognitive state is good, and the stimulus level or cognitive level can be maintained or appropriately increased. This closed-loop feedback mechanism ensures that the intervention intensity always matches the participant's real-time state, achieving truly personalized intervention.
[0043] Understandably, by comparing the real-time acquired assessment physiological signals with pre-stored standard physiological signals using differences or ratios, the subject's real-time physiological response is quantitatively compared with their baseline level, eliminating the interference of individual differences in physiological response on intervention decisions and achieving individualized assessment. Based on this, according to the comparison results and preset thresholds, the stimulus level of the traumatic stimulus or the cognitive level of the cognitive guidance task is dynamically adjusted in real time, forming a closed-loop feedback control from physiological perception to state judgment to parameter adjustment to re-perception. This closed-loop feedback control mechanism allows the intervention intensity to adaptively adjust according to the subject's real-time emotional arousal state. When the subject's response is too strong, it automatically downgrades to reduce the burden; when the response is stable, it moderately upgrades to maintain intervention efficacy, thus ensuring that the stimulus intensity and cognitive difficulty remain within a tolerable and effective dynamic balance range throughout the intervention process. This overcomes the technical shortcomings of fixed intervention parameters that cannot be adjusted according to the subject's real-time state, significantly improving the safety and effectiveness of the intervention process and providing an automatically executable closed-loop control scheme for precise and personalized intervention of traumatic memory.
[0044] In one feasible implementation, refer to Figure 2 , Figure 2 The schematic diagram of the stimulation level adjustment process provided in Embodiment 1 of the trauma memory intervention method of this application, based on the comparison results of the standard physiological signal and the assessment physiological signal, includes steps S301 to S303 for dynamically adjusting the stimulation level of the assessed traumatic stimulus: Step S301: Compare the difference between the standard physiological signal and the evaluation physiological signal to obtain the comparison result; Step S302: When the comparison result is greater than or equal to the first preset threshold, the stimulation level of the assessed traumatic stimulus is reduced. Step S303: When the comparison result is less than the first preset threshold, increase the stimulation level of the traumatic stimulus being evaluated.
[0045] It should be noted that the comparison result is obtained by comparing the difference between the standard physiological signal and the assessment physiological signal. In practical applications, the standard physiological signal is the baseline value of the skin conductance response, and the assessment physiological signal is the current skin conductance response value acquired in real time. When the comparison result is greater than or equal to a first preset threshold, the stimulation level of the traumatic stimulus is reduced. The first preset threshold can be set based on clinical experience or pre-trial data, for example, 50% of the baseline or a ratio of 1.5. When the comparison result exceeds this threshold, it indicates that the subject's current emotional reaction is too strong and has exceeded the expected range, and the stimulation level is automatically reduced by a computer program. The reduction of the stimulation level can be achieved in various ways. For static stimulus images, the brightness or contrast of the image can be reduced, for example, reducing the brightness from 100% to 70%. For audio clips, the volume decibel value can be reduced, for example, reducing the volume from 80 decibels to 60 decibels. For virtual reality scenes, the immersion of the scene can be reduced, for example, by reducing the resolution, frame rate, or reducing dynamic elements in the scene. When the comparison result is less than the first preset threshold, the stimulation level of the traumatic stimulus is increased. If the comparison result is below the threshold, it indicates that the subject's current response is relatively stable or insufficient, and the stimulus level can be appropriately increased to maintain sufficient intervention intensity. The increase in stimulus level corresponds to the decrease, for example, increasing the image brightness from 70% to 80%, or increasing the volume from 60 dB to 70 dB. In practical applications, the stimulus level can be adjusted in a stepwise manner, with each adjustment being a preset step size (e.g., a 5% change in brightness) to avoid causing discomfort to the subject due to excessively large adjustments.
[0046] Preferably, the cognitive guidance task can be preset with 5 difficulty levels, from low to high: Level 1 to Level 5. Different levels impose different cognitive loads on the test taker. When the system determines that the cognitive level needs to be lowered (e.g., from Level 3 to Level 2), the computer automatically switches the guidance presented in the next round from Level 3 content to Level 2 content, and the interactive task format is also simplified accordingly. When it determines that the cognitive level needs to be increased, the corresponding higher-level content is presented. Each adjustment is one level, avoiding discomfort caused by abrupt changes. If the test taker does not complete the current level of cognitive guidance task within the preset time window, or if the system determines through keyword semantic analysis that the test taker's answer still contains significant negative cognitive biases, the system will automatically lower the cognitive level by one level and present more guiding guidance.
[0047] Understandably, by comparing real-time differences and determining thresholds, adaptive adjustment of stimulus intensity is achieved. This avoids the problems of excessive distress caused by overly strong stimuli or ineffective intervention due to underlying stimuli, ensuring that the stimulus intensity is always maintained within an ideal range that effectively activates memory without exceeding the subject's tolerance.
[0048] In one feasible implementation, the step of dynamically adjusting the cognitive level of the cognitive guidance task based on the comparison results of the standard physiological signal and the evaluation physiological signal includes: The difference between the standard physiological signal and the evaluation physiological signal is compared to obtain the comparison result; When the comparison result is greater than or equal to the second preset threshold, the cognitive level of the cognitive guidance task is reduced. When the comparison result is less than the second preset threshold, the cognitive level of the cognitive guidance task is increased.
[0049] It should be noted that the comparison result is obtained by comparing the difference between the standard physiological signal and the assessment physiological signal. This comparison process is the same as in the above embodiment, and can be calculated by difference or ratio, which will not be repeated here. When the comparison result is greater than or equal to the second preset threshold, the cognitive level of the cognitive guidance task is reduced. The second preset threshold can be set independently of the first preset threshold, for example, set to 60% of the baseline or a ratio of 1.6. When the comparison result exceeds this threshold, it indicates that the subject's current physiological response is too strong, possibly accompanied by excessive cognitive load, making it difficult to handle complex cognitive tasks. In this case, the difficulty level of the cognitive guidance task is automatically reduced by a computer program. The reduction of the cognitive level can be achieved in various ways, such as simplifying the instructions from abstract concepts to specific questions, such as simplifying "Please re-evaluate this scenario" to "Please describe which elements in this scenario are safe," or simplifying the interactive task from free-response to multiple-choice questions, such as providing A. This scenario is scary, B. This scenario has safe factors, C. Cannot be evaluated, for the subject to choose from, or reducing the complexity of the language by using simpler and more direct vocabulary. When the comparison result is less than the second preset threshold, the cognitive level of the cognitive guidance task is increased. If the comparison result is below the threshold, it indicates that the subject's current physiological response is stable and their cognitive state is good. The difficulty of the cognitive task can be appropriately increased to promote deeper cognitive restructuring. Improving cognitive level can be achieved in the opposite way to lowering it, such as requiring the subject to conduct more in-depth situational analysis or to reorganize positive cognitive viewpoints in their own words.
[0050] Understandably, by assessing the cognitive load of subjects in real time through physiological signals and dynamically adjusting the difficulty of cognitive tasks, the problems of frustration caused by tasks that are too difficult or insufficient cognitive participation caused by tasks that are too easy are avoided. This ensures that the cognitive guidance tasks are always within the range that subjects can effectively handle, thereby improving the efficiency and effectiveness of cognitive intervention.
[0051] In one feasible implementation, the standard traumatic stimulus includes at least one of a static stimulus image, a stimulus audio clip, or a virtual reality scene.
[0052] It should be noted that static stimulus images refer to static images with trauma-inducing valence, such as war scenes or accident scenes. In practical applications, static stimulus images are presented on a monitor for 3 to 10 seconds, with a resolution typically set to 1920×1080 pixels to ensure image clarity. An appropriate image library can be selected based on the subject's trauma type, such as images with standardized valence scores from the International Emotional Image System. Stimulus audio clips refer to short audio clips with fear-inducing valence, such as screams, explosions, alarms, or crying. In practical applications, these audio clips are played through headphones or speakers for 3 to 10 seconds, with a volume typically set to 60 to 80 decibels to effectively elicit an emotional response. Audio clips can be selected or customized based on the subject's trauma type. Virtual reality scenes refer to immersive three-dimensional environments constructed using virtual reality technology, such as virtual horror rooms, high-altitude scenes, or traffic accident scenes. In practical applications, virtual reality scenes are presented through virtual reality headsets, allowing subjects to view the virtual environment in 360 degrees and experience a sense of presence. The duration of a virtual reality scene can be set according to intervention needs, typically ranging from 30 seconds to 3 minutes. In practical applications, a single stimulus form can be selected based on the subject's type of trauma and intervention needs, or multiple forms can be combined.
[0053] Understandably, by providing diverse stimulus presentation methods, it adapts to the needs of different subjects' sensitivity types and different trauma situations. Its technical effect lies in: improving the applicability and flexibility of this method, enabling it to be applied to a wider range of trauma types and subject populations, including but not limited to traffic accident trauma, natural disasters, and specific phobias.
[0054] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 , Figure 3 The flowchart provided for Embodiment 2 of the trauma memory intervention method of this application, after the step of dynamically adjusting the stimulation level of the assessed traumatic stimulus and / or the cognitive level of the cognitive guidance task based on the comparison results of the standard physiological signal and the assessed physiological signal, further includes steps A10 to A30: Step A10: The subject is subjected to the assessment traumatic stimulus to generate a post-test physiological signal, and the post-test physiological signal is compared with the standard physiological signal to obtain the post-test comparison result; Step A20: Based on the post-test comparison results, generate intervention effect evaluation indicators; Step A30: Evaluate the trauma memory intervention of the subject based on the intervention effect evaluation indicators.
[0055] It should be noted that the process involves assessing the traumatic stimulus on the subjects, generating post-test physiological signals, and comparing these signals with standard physiological signals to obtain post-test comparison results. Specifically, at a predetermined time point after the intervention (e.g., 24 hours later), the subjects are presented with an assessment traumatic stimulus that is related to the standard traumatic stimulus. This assessment traumatic stimulus can be the same as the standard traumatic stimulus or a stimulus with similar valence but different content. Simultaneously with the presentation of the assessment traumatic stimulus, post-test physiological signals such as skin conductance and heart rate are recorded using physiological acquisition devices. The difference or ratio between this post-test physiological signal and the standard physiological signal is calculated to obtain the post-test comparison results. Based on the post-test comparison results, intervention effectiveness evaluation indicators are generated. In practical applications, evaluation rules can be set based on the post-test comparison results. For example, if the post-test physiological signal decreases by more than 50% compared to the standard physiological signal, the evaluation indicator is considered effective. If the decrease is between 30% and 50%, the evaluation indicator is considered partially effective. If the decrease is less than 30% or even increases, the evaluation indicator is considered ineffective. The intervention effectiveness evaluation indicators are used to assess the trauma memory intervention effect on the subjects. The system can automatically generate an assessment report based on preset assessment rules. If the intervention is effective, spontaneous recovery of traumatic memory is significantly blocked, or the intervention is ineffective, a second intervention is recommended. The assessment report can be displayed on the monitor in text form or saved as an electronic document for clinical staff to review.
[0056] Understandably, by comparing changes in physiological signals before and after the intervention, the intervention effect can be quantified using objective physiological indicators. This provides an objective and quantitative means of evaluating the intervention effect, making the intervention effect measurable, comparable, and traceable, providing reliable data support for clinical decision-making, and overcoming the evaluation bias of traditional methods that rely on subjective verbal reports.
[0057] The trauma memory intervention method provided in this application induces target memories by presenting standardized traumatic stimuli to the subject and collecting standard physiological signals generated by the subject through the standardized traumatic stimuli. Within a preset time window after the target memory is induced, the subject is assessed for the traumatic stimuli while simultaneously performing a cognitive guidance task, and the subject's assessment physiological signals are collected in real time. Based on the comparison results of the standard physiological signals and the assessment physiological signals, the stimulation level of the assessed traumatic stimuli and / or the cognitive level of the cognitive guidance task are dynamically adjusted. In other words, this application's embodiments solve the technical problems of strong subjectivity, inaccurate timing, and lack of objective feedback in traditional techniques by constructing an automated intervention system from the memory reconsolidation theoretical window to the cognitive guidance task to real-time physiological feedback. Specifically, by first presenting standardized traumatic stimuli to the subject to induce target memories and collecting individualized standard physiological signals as a baseline, the interference of individual differences on intervention decisions is eliminated, providing a precise reference for subsequent closed-loop regulation. Subsequently, within the memory consolidation window after the target memory is induced, the assessment of traumatic stimuli, the cognitive guidance task, and the real-time acquisition of physiological signals are automatically and synchronously executed. This ensures that the intervention occurs during the critical period when memory is most unstable and easily modified, achieving precise control over the temporal dimension. Based on this, the real-time acquired assessment physiological signals are quantitatively compared with standard physiological signals. The stimulation level of the assessment traumatic stimuli and the cognitive level of the cognitive guidance task are dynamically adjusted according to the comparison results, constructing a closed-loop feedback loop. This allows the intervention intensity to adaptively adjust according to the subject's real-time emotional arousal state; that is, it automatically downgrades when the reaction is too strong to reduce the burden, and moderately upgrades when the reaction is stable to maintain efficacy, thus ensuring that the stimulation intensity and cognitive difficulty are always within a tolerable and effective dynamic balance range. Furthermore, by providing various forms of stimulation, such as static images, audio clips, and virtual reality scenes, the system adapts to the differentiated needs of different trauma types and subject populations. By comparing post-intervention physiological signals with standard physiological signals, an objective quantitative assessment of the intervention effect is achieved. In summary, this study has achieved fully automated, standardized, and personalized closed-loop control of trauma memory intervention, significantly improving the accuracy, safety, and assessability of the intervention. It provides a complete solution for clinical intervention and scientific research on trauma memory that can be automated and standardized for widespread application.
