- What determines the perception of orientations in visual cortex, sharp contours or oriented spatial frequencies? It's the contours, the building blocks for shape. Brilliant paper by Seohee Han out in Scientific Reports: www.nature.com/articles/s41... @uoftpsychology.bsky.social
- Wonderful article about our recent paper in @pnasnexus.org! Thanks, @sachapfeiffer.bsky.social and @mickbonner.bsky.social! @yikai-tang.bsky.social @uoftpsychology.bsky.social @artsci.utoronto.ca @utoronto.ca
- Why do we find some scenes more aesthetic than others? For my first in @sciencenews.bsky.social, I wrote about a new study that suggests that our aesthetic preferences could have evolved as cognitive shortcuts. 🧠🧪 www.sciencenews.org/article/brai...
- I accidentally included the wrong tag. It should be: @sachinxr.bsky.social ! Sorry!
- Reposted by Dirk Bernhardt-Walther🚨 Last publication alert of 2025! Why is scene understanding easier and faster for some scenes than for others? Here, we explore whether scenes with too much information slow visual processing. 1/
- Bridges can anchor communities as landmarks and even tourist destinations, blend into their environment unnoticed, or they can be eyesores. What determines the aesthetic quality of bridges? Mei Yang, @damianoc.bsky.social, Paul Gauvreau, and I explore this question here: doi.org/10.1371/jour...

- Reposted by Dirk Bernhardt-WaltherDimensionality reduction may be the wrong approach to understanding neural representations. Our new paper shows that across human visual cortex, dimensionality is unbounded and scales with dataset size—we show this across nearly four orders of magnitude. journals.plos.org/ploscompbiol...
