Preprint out, from my work with @mamassian.bsky.social and Anne! We show that time perception is shaped not only by context but also by structural constraints, by extending classical Bayesian models by explicitly quantifying a structural prior impacting duration discrimination.

Modeling how contextual and structural biases shape duration perception

Human time perception is flexible and shaped by both structural constraints and contextual influences. Disentangling these sources of bias is essential for understanding the predictive mechanisms unde...

Whoa! This is awesome! Thanks for making and sharing

Grad school me spent way too many hrs fighting matlab to generate dot arrays and extract parameters from pre-existing stimuli. So I built the thing I wish existed: an open-source, browser-based toolbox for generating AND analyzing dot arrays. No MATLAB, no installation, no inherited spaghetti code

Martin Wiener @martinwiener.bsky.social · 15d

Just curious: which part of your experience taking stims adds to the incredulity? (I get and share the neuroscience part, but am genuinely curious about the former)

Martin Wiener @martinwiener.bsky.social · 16d

The irony/paradox is that dopamine also dilates (lengthens) perceived duration. And so motivation/guidance can't be just about minimizing experienced duration - the lengthening can be a cue for reinforcement

Why, yes! Time is completely subjective and contextual. Plenty of work linking motivation/outcomes/timing in the guidance of action (and perception! see: doi.org/10.1177/0956...). But also see: doi.org/10.1016/j.ne... and doi.org/10.1016/j.be... for some fantastic links).

In terms of brain regions, there's been a good number of meta-analyses now on this (here's one direct.mit.edu/jocn/article...

One interesting thing about this finding: People with ADHD commonly experience issues with time perception, which Ritalin is able to restore. Notably, the networks observed here are the same ones we see in timing studies (including insula!)

Benjamin Kay @benjaminkay.bsky.social · 19d

This is your brain on Ritalin. Got your attention? Stimulant medications like Ritalin (methylphenidate) do, but not in the way you might think. They don't act directly on the brain’s attention systems! Find out what's really happening in @cellpress.bsky.social. doi.org/10.1016/j.ce...

Very exciting stuff. Although, maybe what we call the “attention” network isn’t necessarily doing only that (and the other networks may similarly contribute to attention in other ways).

But, as a parent of an ADHD kid, these results match a lot of what I see! Great work!

Martin Wiener @martinwiener.bsky.social · 19d

Very cool and looking forward to reading closely! You might be interested in our recent results on image memorability vs model entropy. We also see a detrimental effect at high levels. Would be curious to explore a connection.
