Auditory Processing Speed Testing Without Motor Response Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current processing speed tests require memory involvement and motor movement, making them ineffective for certain patients, such as those with multiple sclerosis, and may produce inaccurate results.
Innovation Solution
A computer-implemented method and system for testing mental speed using auditory stimuli and responses, administered via a speaker and microphone, without requiring motor movement, and allowing for real-time calculation and display of results.

Engineering Contradiction Analysis
1Reliability
If current processing speed tests are used, then memory involvement and motor movement are required, but this makes the tests ineffective for patients with motor impairments and may produce inaccurate results
Solution Approach 1:
The patent replaces motor movement requirements with auditory stimulus-response tasks. Instead of requiring physical actions (button presses, eye movements), the system uses audio presentations and audio responses, substituting mechanical interaction with acoustic interaction. This allows patients with motor impairments to complete processing speed tests without requiring functional motor skills.
Solution Approach 2:
The patent extracts and removes the memory and motor components from traditional processing speed tests. By isolating the core cognitive processing element and eliminating confounding factors (memory load, motor execution), the test purelly measures mental processing speed without contamination from other cognitive or physical abilities.
2Ease of operation
If auditory stimulus-response method is used, then motor movement requirements are eliminated, but the system complexity increases with multiple tests and instructions
Solution Approach 1:
The patent combines multiple test administrations into a single integrated system. The computer-implemented method delivers multiple auditory tests with different instruction sets through a unified interface, automatically managing test sequences, timing, and result aggregation. This merging reduces the operational burden despite the increased number of test components.
Solution Approach 2:
The system automatically presents instructions, administers tests, calculates results, and displays outcomes without requiring manual intervention. The computer-implemented method self-manages the entire testing workflow, from delivering auditory stimuli through the speaker to processing responses via microphone and generating final scores, reducing the complexity burden on operators.
