About

Jameson K. Holden is a researcher focused on the critical intersection of sports medicine, neuropsychology, and digital assessment methodology. His work centers on the validity and reliability of computerized concussion testing, with a particular emphasis on the technical flaws inherent in measuring reaction time—a key metric in cognitive health evaluations. Holden’s major contributions include identifying and quantifying methodological problems in online concussion assessments, demonstrating that consumer-grade computer systems introduce significant measurement errors that can compromise clinical decisions. His 2020 paper "Methodological Problems With Online Concussion Testing" (18 citations) serves as a foundational critique, while his companion studies on visual versus tactile reaction testing (11 citations) and the potential for accurate reaction time metrics (11 citations) collectively underscore the need for hardware-validated protocols. By exposing the gap between widespread clinical use and technical rigor, Holden has pushed the field toward more objective, reproducible concussion diagnostics. His work is essential reading for researchers and clinicians developing digital cognitive tools, highlighting that without addressing these fundamental measurement issues, the validity of online neuropsychological assessments remains in question.
