Title:
COGNITIVE DECISION-MAKING EVALUATION METHOD AND SYSTEM BASED ON MULTI-DIMENSIONAL HIERARCHICAL DRIFT DIFFUSION MODEL
Document Type and Number:
WIPO Patent Application WO/2023/087917
Kind Code:
A1
Abstract:
Disclosed in the present invention are a cognitive decision-making evaluation method and system based on a multi-dimensional hierarchical drift diffusion model. The method comprises the following steps: for a healthy subject, establishing a multi-dimensional hierarchical drift diffusion model on a group level, and obtaining a sensitivity threshold value and a probability distribution thereof for the healthy subject in each cognitive domain, and a sensitivity threshold value and a probability distribution thereof in terms of overall meta-cognitive processing efficiency, so as to serve as a healthy person common model; and for each MCI patient, establishing a multi-dimensional hierarchical drift diffusion model on an individual level, and obtaining a sensitivity threshold value and a probability distribution thereof for the MCI patient in each cognitive domain, and a sensitivity threshold value and a probability distribution thereof in terms of overall meta-cognitive processing efficiency, so as to serve as indicators to be measured. By means of performing comparison on the relative positions of parameters of an MCI patient that are distributed in a healthy person common model, the damaged capability of the MCI patient can be accurately evaluated, thereby prompting early discovery, early intervention and early treatment for the damaged decision-making capability.
