Interoception refers to the sensation of internal bodily signals. When studying sensory perception, one needs measurements for assessing individual abilities. Individual interoceptive abilities have mostly been measured by a heartbeat counting task, however recent criticism towards the validity of the task has surfaced. A limiting factor remaining for interoceptive research is the lack of standardized valid measurements for individual abilities. In this context, new measurements have been proposed, such as a thermal matching task. In the present study, I examine the reliability of the new thermal matching task, as well as the relationship between skin-mediated interoceptive sensations and cardiac interoception. The thermal matching task was found to be temporally stable on the dorsal forearm, but not on the dorsal hand or palm. Furthermore, participants were significantly better at the task on the dorsal forearm compared to dorsal hand and palm. There were also differences in the task between genders, however whether this is due to gender effects or associated confounding variables remains unclear. The thermal matching task shows potential to be included as a measure for thermal perception in an interoceptive context. Future research should address the relationship between the thermal matching task and other measurements of thermal perception.
