The study of the brain's processing sensory inputs from within body ('interoception') has been gaining rapid popularity in neuroscience, where interoceptive disturbances are thought to exist across a wide range chronic physiological and psychological conditions. Here we present task analysis procedure quantify specific dimensions breathing-related interoception, including sensitivity, decision bias, metacognitive performance. Two major developments address some challenges presented by low trial numbers experiments: (i) novel adaptive algorithm maintain performance at 70–75% accuracy; (ii) an extended hierarchical model estimate regression parameters linking relevant (e.g. clinical) variables. We demonstrate utility developments, using both simulated data three empirical datasets. This methodology represents important step towards accurately quantifying simple experimental that is compatible with clinical settings.
