Background & Purpose: Processing, perceiving, and representing internal bodily information underlie interoceptive awareness (IA), an elemental component in selfconsciousness. Heartbeat perception remains a reliable method of measuring IA, and contemporary research demonstrates its efficacy in delineating individuals with high versus poor IA. At a cortical level, heartbeat-evoked potentials (HEP), synchronized to the R-wave peak, have provided reliable insight into the cognitive and attentional processes associated with heartbeat perception accuracy. To date, however, no study has measured IA and HEP in relation to emotional experience and emotion induction...
