ABSTRACT

Interoception and impulsivity are two multi-dimensional constructs and although the role of interoception in impulsiveness has been previously reported, it is not clear whether their different facets are related to each other. In the present study, we aimed at bridging this gap by investigating the relationships between interoception and impulsivity in the light of their multi-dimensional nature. To this aim, we conducted a cross-task comparison and assessed in the same sample of healthy participants, interoceptive accuracy, by the heartbeat perception task, interoceptive sensibility, by a self-reported measure, "hot" impulsivity, by a behavioural task of risk taking, and "cool" impulsivity, by a go/no-go task. Also, we assessed trait impulsivity by a self-report measure. We found that interoceptive sensibility contributed to "hot" impulsivity, while interoceptive accuracy was related to non-planning trait impulsivity. These findings underscore the need to investigate at a finer grain the relationships between these two complex, multi-dimensional constructs.
