Does contingent biofeedback improve cardiac interoception? A preregistered replication of Meyerholz, Irzinger, Withoft, Gerlach, and Pohl (2019) using the heartbeat discrimination task in a randomised control trial.

ABSTRACT: Meyerholz, Irzinger, Withöft, Gerlach, and Pohl (2019) reported on a comparably large effect (d = 1.21) of a contingent biofeedback procedure on cardiac accuracy as assessed by the heartbeat tracking task. However, this task has recently been criticized as a measure of interoceptive accuracy. We aimed to replicate this finding by using the well-validated heartbeat discrimination task and to compare the biofeedback with a deep breathing and a control condition (viewing a film clip). The trial was preregistered at open science framework (https://osf.io/9fxn6). Overall, 93 participants were randomized to one of the three conditions and the heartbeat discrimination task was presented prior and after the 20-minutes training sessions. The study had a power of .86 to detect a medium-sized effect
