Description
Robin Orthey and co-authors tested a lie-detection method in work published in 2025, though catalogued under 2026, on older adults. The concealed information test reads body signals to spot hidden knowledge of crime details, and it is used often in Japan. Nearly all its validation comes from young students, while ageing dulls body responses.
Thirty-three seniors aged sixty-two to eighty took the test in knowing and ignorant conditions. Skin conductance still detected hidden knowledge, though more seniors gave no response than expected. Heart rate worked only after a baseline fix, and breathing failed. All three signals weaken with age, so senior results need caution and adapted analysis, the authors warn.
