This research develops a new Bayesian model for measuring perception thresholds in individuals, suggesting improved methods for studying cognition.

The aim is to create a Bayesian hierarchical model to better assess individual differences in psychophysical tasks.
Developed a random-intercept psychophysical model for small-trial designs.
Jointly modeled variation across trials and individuals using Bayesian methods.
Assessed subliminal versus superliminal stimulation using custom-tailored thresholds.
The model effectively measures thresholds with fewer trials while accounting for individual variation.
Correlations between tasks are less skewed by trial noise, yielding more accurate assessments.
Offers measures of uncertainty impacted by participant and trial counts.

Rouder et al. (2026) studied this question.
