Time Perception
The Heart Can Sway Our Perception of Time
By Anton Benz & Daisy Yuhas in Scientific America (2023) First, it races away unstoppably—then it seems to stand still. Our perception of time is anything but constant. Two new studies suggest our heartbeat can cause passing moments to drag or fly. The experiments, led by separate research groups, have uncovered complementary…
Perceived time expands and contracts within each heartbeat
Do you ever feel like time slows down when you’re bored but flies when you’re having fun? Let’s explore the ways your brain and heart shape your perception of time, revealing how your heartbeat doesn’t just keep you alive — it also influences whether moments feel…
In search of experienced time: how the heart-brain coupling supports time perception
Combining a novel experimental paradigm with cutting-edge neuroimaging, Irena Arslanova aims to establish that time awareness arises from an intricate brain–body interplay.
Interoception
People Can Tell How Fast Your Heart Is Beating Just by Looking at You
A preprint paper, published online on March 29, replicated the finding that people can guess another’s heartbeat just by looking at them. The researchers, with first author Irena Arslanova, did an additional measurement: They also looked to see how well people did at assessing their own heart rate, or their interoceptive accuracy. This is often done…
Seeing through each other’s hearts: inferring others’ heart rate as a function of own heart rate perception and perceived social intelligence
Do you ever feel like time slows down when you’re bored but flies when you’re having fun? Let’s explore the ways your brain and heart shape your perception of time, revealing how your heartbeat doesn’t just keep you alive — it also influences whether moments feel fleeting or stretched.
