3D Memory Assessment Tool for Cognitive Impairment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current neuropsychological assessments for memory and learning are not suitable for young children or individuals with cognitive impairments, as they often require a minimum level of cognitive function and do not account for varying levels of attention, language, and motor proficiency, lacking comprehensive measures across the lifespan.
Innovation Solution
A system utilizing a three-dimensional memory assessment tool with translucent containers and recognizable objects, designed to assess verbal and visuospatial memory, executive functions, and other cognitive processes, suitable for diverse populations, including young children and those with cognitive impairments, through a comprehensive and adaptable assessment method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional neuropsychological assessments are used, then cognitive ability can be assessed in typically-developing populations, but they are not suitable for young children or individuals with cognitive impairments due to requiring minimum cognitive function levels
Solution Approach 1:
The patent modifies assessment parameters by using three-dimensional transparent containers instead of traditional two-dimensional surfaces, creating visual contrast areas that can be perceived by individuals with varying cognitive abilities. The containers are arranged in specific patterns and filled with objects to create assessable memory tasks that adapt to different population needs while maintaining measurement reliability
2Ease of operation
If assessments are made simpler for young children and cognitively impaired individuals, then accessibility improves, but comprehensive coverage of memory processes and cognitive development may be reduced
Solution Approach 1:
The three-dimensional container array serves multiple assessment functions simultaneously - it can evaluate spatial memory, object recognition, working memory, and episodic memory within a single unified apparatus. The same basic structure supports tasks of varying complexity levels, allowing comprehensive cognitive assessment while maintaining ease of operation across different populations
3Measurement precision
If existing assessments are used for populations with cognitive impairments, then some memory measures can be obtained, but they lack developmentally appropriate and sensitive measures for children under 5 years old
Solution Approach 1:
The assessment system is designed to be dynamic and adaptable, allowing the same basic apparatus to be configured for different developmental stages. The containers can be arranged in age-appropriate patterns, and the number and type of objects placed within them can be adjusted to match the cognitive development level of the participant, enabling precise measurement across the entire lifespan from early childhood through adulthood

AI summary
A hiding board includes a flat surface; and a plurality of containers arranged in a random fashion on the flat surface and secured thereto, each container being configured to receive a three-dimensional object from a user. A method for neuropsychological assessment includes presenting one or more three-dimensional objects to a participant in a first arrangement on a hiding board; removing the one or more three-dimensional objects from the hiding board; re-presenting the one or more three-dimensional objects to the participant in an arrangement that is different from the first arrangement; and tasking the participant with recreating the first arrangement.
