Schematic outline of the Phase Adjustment Training Task. At T1, the participant adjusts the dial until the delay between the beats matches that of their own heart rate. At T2, the participant rates how confident they felt with their score, from not at all confident to extremely confident. T3 is the novel component added in our intervention, where the participant receives feedback based on their accuracy. Marks to the left of the centre indicate the participant was too slow, whereas marks to the right indicate the participant is too fast. The green numbering refers to the number of points collected on the task. Finally, Tx is the final score participant received in the session
