Subclaims¶

q3 i? Of 21 studies measuring HRV and performance data, only 4 fell into the high-correlation group while 11 were uncorrelated, indicating limited predictive validity. → Hyun Jin Kim 2024 q3 i? All three studies co-measuring test scores reported no correlation between test scores and HRV data, and two of three skill-assessment studies provided evidence against HRV predictive validity. → Hyun Jin Kim 2024 (2)

q3 · i? · quant-synthesis · r2

Systematic review synthesis of predictive validity: among 21 studies co-measuring HRV and performance, only 4 reached the L1/L2 correlation group while 11 were uncorrelated. No effect sizes are printed; the review reports counts only.

"Among the 21 studies that measured HRV and performance data, only 4 studies fell into the L1/L2 group, with 11 studies in the L4 group."

q3 · i? · review · r3

Within the review's predictive-validity analysis of stress studies, the authors report that all three test-score studies found no correlation and two of three skill-assessment studies argued against predictive validity; two PVT studies indicated low predictive validity for attention.

"All three studies that co‑measured test scores reported no correlation between test scores and HRV data, and two out of three studies that used skill assessment data provided evidence against the predictive validity of HRV."
