In this Article, Ma et al. show, across a series of experiments, that time and memorability (the probability of recalling a visual stimulus) mutually influence one another, suggesting that time is a f...

Excited and thrilled and humbled that our work is now out at Nature Human Behaviour linking Memorability with Time Perception! I hope you all find it of interest π

Very exciting stuff. Although, maybe what we call the βattentionβ network isnβt 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!

The Speed Limit of Visual Perception: Bidirectional influence of image memorability and processing speed on perceived duration and memory recall
Visual stimuli are known to vary in their perceived duration, with some stimuli engendering so-called βtime dilationβ and others βtime compressionβ effects. Previous theories have suggested these effe...

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.

Beyond all this, we found that shapes/symbols with more edges were also processed faster in recurrent models of vision, and were also predicted to be more memorable.
Altogether, we think this provides evidence that visual time is guided by information content.

Here, we found that the durations of images that required more steps to generate were both dilated AND more precise. In the image below the ones on the right were seen as longer than the ones on the right.
ALSO, the effect was moderated by how subjectively meaningful subjects found the stimuli

So what's going on? Do angles matter? We turned to more complicated symbols, both artificial and real:
Here, we found that symbols that contained more edges were dilated. In the attached image, the symbols on the right all seemed to last longer than the ones on the left.

To answer this, we turned to intermediate layers of vision. We started out with the popular "Bouba Kiki" set. We found that the durations of more angular shapes ("Kiki"-like) were perceived more precisely and faster, modified by how large people perceived them and how consistently they named them.
