❤️ New research in Biological Psychology reveals our hearts slow down when we make visual mistakes, even before we realize it. This suggests our bodies react to perceptual errors as they happen.

🧠 Historically, focus has been on the brain, but this study shows a constant dialogue between the brain and the body's nervous system, including the heart, influences our conscious perception.

🔬 Experiments with 24-26 participants showed heart rate decelerated more during perceptual illusions (mistaking letter color) than during correct perceptions, suggesting the heartbeat signals unexpected events or errors.

💡 The takeaway for the public: your body constantly influences how you perceive the world, often unconsciously. Conscious experience arises from the brain-body conversation, not just the brain alone.

🧠 Respiration acts as an internal metronome, influencing brain networks for snap judgments. Slowing breath can reorganize sensory processing.
