Is cognition a universal feature of the living world? How can we define it? Is a nervous system needed? If so, why? If not, why not? Check this fascinating @royalsocietypublishing.org Theme Issue led by @drmichaellevin.bsky.social & co. on Basal Cognition royalsocietypublishing.org/doi/pdf/10.1...

Check out our new preprint on how environmental deformation and locomotion affect 3D maps! Co-led with @reisnerv.bsky.social, alongside Leonard König, Misun Kim, and Christian Doeller. Very proud of this work!
Curious about spatial memory in 3D? Our new preprint explores how environmental boundaries and the way we move affect our memory for locations in volumetric space!
Huge congrats to co-1st @theoschaefer.bsky.social w/ Leonard König, Misun Kim, Christian Doeller.

Locomotion-dependent use of geometric and body cues in humans mapping 3D space
The ability to represent locations across multiple dimensions of space is a core function of cognitive maps. While the influence of boundary-dependent environmental geometry on spatial representations...

Does the culture you grow up in shape the way you see the world? In a new Psych Review paper, @chazfirestone.bsky.social & I tackle this centuries-old question using the Müller-Lyer illusion as a case study. Come think through one of history's mysteries with us🧵(1/13):

It’s a Preprint! 👋
We show how we can dissociate perceptual from value-based mechanisms of generalisation + that stronger gen. in anxiety is associated with value rather than perception.

Sleep microstructure organizes memory replay - Nature
The temporal microstructure of the brain can multiplex distinct cognitive processes during sleep to support continuous learning.
