Boredom on many levels of inquiry: as body feelings, subjective slowing down of time, and related insular cortex activity. Review out by @wanjawolff.bsky.social and team.

Wanja Wolff @wanjawolff.bsky.social · 23d

📢 Now accepted at Neuroscience & Biobehavioral Reviews 🤩

Our proposal offers a framework for understanding how fundamental regulatory sensations, such as boredom & effort, shape temporal experience through interoceptive mechanisms.

🎉 Happy to share our latest paper on #Physiology&Behavior @elsevierconnect.bsky.social
Together with Luigi Micillo, Nicola Cellini and Giovanna Mioni we explored the link between cardiac #interoception and time perception

The TIMED project www.timed-europe.net reveals: The more we live in the online world, and the more we enjoy and benefit from that immersion, the more quickly life seems to speed by. The good news? This effect is relatively small—but measurable: osf.io/preprints/ps...

How do the body and brain process time? Evidence from neuroimaging, neurophysiological, electrophysiological, and patient-based studies suggest that time perception is grounded in interoceptive (insula) and sensorimotor processing (SMA). Preprint with Alice Teghil osf.io/preprints/ps...

The Bodily Self, Emotion, and Subjective Time

This book provides a comprehensive exploration of the interplay between the bodily self, emotion, and subjective time perception and consciousness.

I think that Craig would agree with most parts of your thread when he expounds that emotional moments are the integration of body signals with motivational and cognitive states. That is your "bidirectional interplay between bodily sensations, the narrative self, and metacognitive self-appraisal".

Time and Existence: How Artists Try to Grasp the Ineffable

Contemporary artists find different expressions to cope with existential aspects of time referring to either the expiring life (chronos) or the passing moment to moment (kairos).
