Spent the morning writing a lecture on computational modelling of visual short-term memory, and I get to talk extensively about our paper in press at QJEP (with @sbmoore.bsky.social)!

Oxford’s new “Life & Mind” Building brings Biology and Experimental Psychology together, an example of how psychology thrives as an empirical, theory-driven, biological, and computational science. You can feel the intellectual energy there already!

Really fascinating discovery. But also fascinating how this came about (and what a shame we can't write it like this in papers!)
In this new preprint, in review @elife.bsky.social, we show what processing steps make up the reaction time using single trial #EEG modelling in a contrast #decision task.
In this 🧵 I'm telling the story behind it as I think it is quite interesting and I can't write it like this in the paper...

I've spent the past weeks publishing my flankr package on CRAN for R. Users who've only installed the first version will notice SIGNIFICANT improvements in model fit speed.
Plus, I made a hex sticker for it.

Well this is a delightfully clever study. Check it out.
On the left is a rabbit. On the right is an elephant. But guess what: They’re the *same image*, rotated 90°!
In @currentbiology.bsky.social, @chazfirestone.bsky.social & I show how these images—known as “visual anagrams”—can help solve a longstanding problem in cognitive science. bit.ly/45BVnCZ

Hot take: Some computational modellers don't share readable, complete code—or offer help when asked—because gatekeeping methods gives them a professional edge. It's bad for science and worse for collaboration.
