Abstract: Heartbeats are strongly related to emotions, and people are known to interpret their own heartbeat as emotional information. To explore how people interpret other’s cardiac activity, the authors conducted four experiments. In the first experiment, they aurally presented ten different levels of heart rate to participants and compare emotional intensity ratings. In the second experiment, the authors compare the effects of nine levels of heart rate variability around 0.10 Hz and 0.30 Hz on emotional intensity ratings. In the third experiment, they combined manipulations of heart rate and heart rate variability to compare their effects. Finally, in the fourth experiment, they compare effects of heart rate to effects of angry versus neutral facial expressions, again on emotional intensity ratings. Overall, results show that people relate increases in heart rate to increases in emotional intensity. These effects were similar to effects of the facial expressions. This shows possibilities for using human interpretations of heart rate in communication applications.
