How Your Heartbeat Shapes Your Perception of Time

Irena Arslanova, a cognitive neuroscientist, discusses how our heartbeat influences our perception of time. She explains that the brain and heart are in a rhythmic dance, with the brain stepping into an active mode with each heartbeat and into a perceptual mode between beats. This rhythm can cause our perception of time to contract and expand. Her research found that stimuli occurring during the heart's contraction were perceived to last shorter than those occurring between beats. This suggests that our perception of time is an embodied experience, shaped by the body as well as the brain.
