New work on sensory prediction resolves some long-standing puzzles about attenuation of self-touch journals.physiology.org/doi/full/10.11…

Now out in Comms Psych: the "anti-Bayesian" size-weight illusion is a consequence of the brain focusing resources on encoding typical combinations of size and weight (i.e. "efficient coding"). Explains the material-weight illusion too nature.com/articles/s4427…

We have an opening for a postdoc to work on a collaborative project with @lengyel_m (UCambridge Engineering) combining machine learning methods with human experiments on visual perception and memory jobs.cam.ac.uk/job/49299/

👀Claude handles an insane request: “Remove the squid” “The document appears to be the full text of the novel "All Quiet on the Western Front" by Erich Maria Remarque. It doesn't contain any mention of squid that I can see.” “Figure out a way to remove the 🦑​​​​​​​​​​​​​​​​“

A systematic dissection of the analogue report methodology and comparison with "gold-standard" 2AFC. Key findings: motor noise is negligible; analogue report error is a robust measure of memory fidelity, but may underestimate perceptual precision doi.org/10.3758/s13428…

Almost two years in the making!

Out now in NHB (finally!), a review of visual working memory from a computational perspective, with @weijima01 @timothyfbrady and Sebastian Schneegans. nature.com/articles/s4156…

Nice commentary from @salinas_urgent and @mangosheikh_B on our new eLife paper doi.org/10.7554/eLife.…

@gershbrain @PhilCorlett1 @chazfirestone Yes, I believe so. It's a dramatic demo (I tried it at VSS once) but doesn't need any extra mechanism to explain it over the standard illusion.

@BaysLab @PhilCorlett1 Cool! I was wondering if the model can explain this incredible version of the illusion by Won et al: direct.mit.edu/opmi/article/d… @chazfirestone let me do it myself in his office and it's truly wild.

The size-weight illusion is a by-product of efficient sensory coding adapted to the combinations of volume and mass found in everyday objects. New preprint biorxiv.org/content/10.110…

1/ 🔥 Hot off the press: my latest paper in collaboration with @BaysLab and @ReubenRideaux. Ever wondered how Bayes' theorem is implemented by the brain? We think we have an answer, for visual orientation estimates at least. 🧵 Open access: nature.com/articles/s4146…

“Among articles stating that data was available upon request, only 17% shared data upon request.” psyarxiv.com/jbu9r/

We measured how effectively observers can reallocate working memory resources to new visual items when old ones become obsolete - people are surprisingly good at it! New paper with @ivntmc @dataforyounz @DAagtenMurphy link.springer.com/article/10.375…

A critique of the psychological similarity account of working memory errors: work with @ivntmc now out in JEP:LMC biorxiv.org/content/10.110…

New review on visual working memory with @BaysLab, @timothyfbrady, and Sebastian Schneegans: psyarxiv.com/kubr9/ I was surprised by how much news there was since my 2014 review with @BaysLab and @MasudHusain. Comments/excoriations are welcome and may get incorporated.

New work with Jess McMaster & others: we show swap errors (item confusions) in cued recall are not a strategic response to forgotten items, but instead occur at exactly the rate predicted by variability in recall of the cue features sciencedirect.com/science/articl…

@StokesNeuro So sorry Mark. Wishing you the very best and hoping the news gets better soon.

Happy 2022 everyone! This year will be especially significant for me. In 2020 I was diagnosed w cancer. Prognosis not v promising. After 6 months treatment, things started to look up, but by the end of 2021 cancer came back. Now restarted chemo, & planning to make v most of 2022

We have an opening for a post-doc (or potentially a talented graduate RA) to research computational mechanisms of visual perception/memory using online and offline experiments - note deadline 11 Aug jobs.cam.ac.uk/job/30738/
