- 05:31Results: QUEST Estimation Procedure Efficiently Yields Robust Estimates of Stimulation Intensity
- 06:11Conclusion
Psychophysical methods such as the QUEST estimation procedure can efficiently yield robust estimates of the stimulation intensity at which nonpainful sensations transition into painful sensations. By stimulating repeatedly at the threshold intensity, the variability in rating responses can directly be attributed to perceptual classifications in subsequent analyses.
