More news on interoception and time perception!

A fascinating case of falsification of our strong and convincing hypothesis with lead author Alice Teghil: Memory encoding for new information, not autobiographical memory load, predicts age-related acceleration in subjective time passage over the last decade osf.io/preprints/ps...

Silence, darkness, and gravity: A qualitative analysis of individual experiences during Floatation-REST Background: In Floatation-REST (Reduced Environmental Stimulation Therapy), an individual lies on the surface of highly saline water in a dark and silent environment.

Our first qualitative methods article in the @degruyterbrill.bsky.social journal Spiritual Care on "Silence, darkness, and gravity: A qualitative analysis of individual experiences during Floatation-REST" now available: www.degruyterbrill.com/document/doi...

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.

Alice Teghil writes about body processes in retrospective timing:

Marc Wittmann & Sylvie Droit-Volet on how the body informs about time passage:

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".

Ever had any strange experiences? We're looking for adults aged 45-60 years living in North of England to take part in our research. Get in touch if interested, there'll be some great discussions and free supper!

As exciting as being in "flow" is researching it! We present a new continuous subjective measure that doesn't interfere with flow to to temporally connect subjective experience with physiological data osf.io/preprints/os...

Frontiers | Stoicism, mindfulness, and the brain: the empirical foundations of second-order desires

Free will is real: It arises from a meta-cognitive ability or hierarchical, second-order will that can causally influence or override first-order desires or impulsive habits. @frontiersin.bsky.social article by me, Carlos Montemayor, & Mauro Dorato just published: www.frontiersin.org/journals/psy...
