Decision-Making Evaluation Using High-Fidelity Video Stimuli
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing decision-making in response to video stimuli lack the fidelity to evoke context-specific neural activity, as they rely on low-fidelity simulations and are not specific to the context of the cognitive skills being measured, making them inadequate for assessing expertise in real-life situations.
Innovation Solution
The use of high-definition video recordings that accurately depict context-specific events, combined with precise time-locking and annotation of neural and behavioral responses, allows for a more immersive and faithful measurement of cognitive skills by simulating real-life scenarios and integrating neural and behavioral metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If low-fidelity simulations (computerized graphics or animations) are used to present stimuli, then the ease of controlling precise events is improved, but the fidelity to evoke context-specific neural activity deteriorates
Solution Approach 1:
The patent uses high-definition video recordings as realistic copies of real-world scenes rather than simplified computerized graphics. These video copies maintain the authenticity of contextual cues while allowing for precise temporal annotation of events, thus resolving the contradiction between ease of control and measurement fidelity.
2Ease of operation
If generic cognitive tests are used, then the ease of administration is improved, but the specificity to context (sport or activity) deteriorates
Solution Approach 1:
The patent applies local quality by customizing the video stimuli and annotation schemes to match specific contextual domains (e.g., football scenes for athletic decision-making). Each test is tailored to the specific context while maintaining a standardized data collection framework, thus achieving both ease of administration and context-specificity.
3Measurement precision
If high-definition video recordings are used, then the fidelity to evoke natural responses is improved, but the complexity of precise time-locking and annotation deteriorates
Solution Approach 1:
The patent employs preliminary action by pre-annotating video recordings with precise temporal markers for relevant events before presentation to subjects. This pre-processing step establishes a reference framework that simplifies the subsequent alignment of neural and behavioral data, reducing the complexity of real-time synchronization.
4Reliability
If real-world video recordings are used instead of controlled events, then the ecological validity is improved, but the ability to lock neuroimaging data to precise events deteriorates
Solution Approach 1:
The patent introduces an intermediary layer of temporal annotation markers that are superimposed on the real-world video recordings. These markers serve as mediators that bridge the authentic visual content with the precise temporal reference needed for neuroimaging data alignment, thus maintaining both ecological validity and measurement precision.
Data Source
AI summary
Systems and methods to analyze decision-making. A processor accesses at least one storage medium storing a high-fidelity recording, the high-fidelity recording includes a stimulus event and one or more rules associated with the stimulus event. The processor presents the high-fidelity recording through a presentation device. The processor receives neural metrics from a neural sensor while the high-fidelity recording is being presented. The processor applies rules to generate reference metrics associated with the stimulus event. The processor modifies elements of the high-fidelity recording based on the reference metrics to distinguish the stimulus event within the high fidelity recording. The processor presents the modified recording by the presentation device.
