Multi-level Executive Functioning Assessment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing executive functioning tests struggle to detect cognitive decline in high-ability individuals, as they often pass standard tests despite impairment, due to the tests' inability to account for real-life distractions and higher cognitive demands.
Innovation Solution
A system that administers multi-level executive functioning tasks with integrated visual and auditory distractions, requiring users to perform multiple executive functions simultaneously, mimicking real-life conditions and increasing the sensitivity of assessments for higher-ability individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard executive functioning tests are administered, then ease of operation is maintained, but measurement precision deteriorates for high-ability individuals
Solution Approach 1:
The test is divided into multiple levels (Level 1, Level 2, Level 3) with progressively increasing complexity. Each level introduces additional executive function requirements and distractions, allowing the system to segment the assessment into manageable components that can be adapted to different ability levels while maintaining measurement precision.
Solution Approach 2:
The test dynamically adapts its complexity based on user performance. The system adjusts the number of distractions, types of executive functions required, and task difficulty in real-time, transforming a static test into a dynamic assessment that maintains optimal challenge and measurement accuracy for individuals of varying abilities.
2Measurement precision
If multi-level tasks with distractions are introduced, then measurement precision improves for high-ability individuals, but device complexity increases
Solution Approach 1:
The test platform is designed to universally accommodate multiple test levels and distraction types within a single system. The same interface and task structure can deliver Level 1, Level 2, and Level 3 assessments, as well as various distraction conditions, making the complex system universally applicable across different ability levels without requiring separate test administrations.
3Reliability
If standard tests are used, then ease of operation is maintained, but reliability deteriorates in detecting cognitive impairment
Solution Approach 1:
The system automatically administers and scores the multi-level assessments without requiring complex manual intervention. The platform self-manages task presentation, distraction delivery, response tracking, and scoring calculations, maintaining ease of operation while incorporating sophisticated multi-level testing that improves reliability of cognitive impairment detection.
4Measurement precision
If real-life distractions are integrated, then measurement precision improves, but object-affected harmful factors increase
Solution Approach 1:
The system converts the potentially harmful effect of distractions (which could interfere with task completion) into a beneficial measurement tool. By systematically introducing visual and auditory distractions that mimic real-life conditions, the test transforms interference into a feature that reveals how individuals maintain cognitive function under challenging conditions, thereby improving measurement precision.

AI summary
Systems and methods of the present invention provide for generating a first, second, and third series of interface objects comprising a first and second sequence respectively, displayed on a graphical user interface (GUI). At least one visual indicator display object is also displayed that requires a switch between the first and second series of user interface objects. A user navigates through the first and second series of interface objects, including the visual indicator display object(s), and a score for the user is calculated according to a user input matching, or failing to match, a correct response associated with a task data defining a function skill demonstrating a cognitive ability of the user.
