Vision scientists and horror film enthusiast. I can’t read or send DMs because Australia banned social media accounts for people under 16…. You do the maths. I also lecture at the University of the Sunshine Coast when I'm not at the beach.

Provocative new preprint examines 14 published meta-analyses claiming AI improves student learning and concludes... Not a single one provides a valid basis for its claims, citing widespread methodological flaws. osf.io/preprints/ed... Watch a webinar from yesterday about the findings:

This is unfortunately a trend that I've noticed in LLM marketing in the last year where they *very directly* are marketing to people by going, "Hey, you're fucking lazy, right? Use our product."
The first genuinely honest ad for generative AI I've ever seen, from Microsoft / CoPilot A mediocre white guy sees his non-white colleague getting praised for good work, he asks AI to *literally copy it*, and then he gets all the praise instead: www.ispot.tv/ad/SoDi/micr...

Uh, yeah, there seemed to be fewer left-handed people until being left-handed was no longer considered unlucky or sinister…
Young teenagers are less likely to identify as lesbian, gay or bisexual than a few years ago, according to a new analysis. “It really does look like a free fall,” Jean Twenge, a professor of psychology, said. “But what’s causing it is unclear.”

New working paper: the Norwegian wealth tax was a huge success. The "exodus" of wealthy people never happened (less than 100 individuals left). Tax revenue increased by 71.5%. No changes in business activity or investment. www.nber.org/papers/w35854
This is critical and missed by many researchers. We don't necessarily understand something just because a DNN or LMM can reproduce him-like responses; that just means that the responses can be learned from a dataset/architecture. A psychologist/neuroscientist's target is the mind, not the model.
The core question still remains, of course. It’s not at all like we’ve actually figured out the algorithms of the brain. The deep learning paradigm did give the problem theoretical structure. Some see this as a useful framework (I do!), which is a positive... (6/n)
This looks like a positive change, but the devil will be in the details: how many “highly competitive” allocations can be made, and what is the expected number of funded grants based on review vs lottery?
ARC has given some details of how new Explore scheme will run ▶️ www.arc.gov.au/news-and-pub... ❗️There's a lottery❗️ Peer review yields 3 categories: highly competitive, competitive, uncompetitive. After funding highly competitive apps, competitive ones enter a lottery for remaining $.

We let AI companies soak up all the IP in the world but dammit if we let them take our maths. If this is the straw that achieves change then so be it.

When I hear an AI model solved an old maths problem, I ask myself: 1) How many human mathematicians were involved? 2) How much money and freedom were the mathematicians paid to solve the problem? My null hypothesis is that the multi-billion dollar models are not the critical ingredient.
this story is crazy. also, looks like academia's not so obsolete after all.
We should all be ashamed.
🚨Update: Our analysis of global APC expenditure has now been expanded to cover more publishers (7 -> 14) and more years (2019-2025). We estimate $15B in APCs paid over seven years, $3.7B in 2025 alone. Elsevier crosses the $1B threshold by itself in 2025. arxiv.org/abs/2608.16322 #ScholComm

🚨 Preprint! We combine our recent open dataset of #APC prices with the article counts per journal-year from #OpenAlex to estimate how much the academic community has paid in APCs over the last 5 years. A. $8.349 billion ($8.968 B in 2023 USD) $2.5B in 2023 alone. arxiv.org/abs/2407.16551 #metasci
This reads a bit like, "Now that we've built such huge complex models that aren't really interpretable, we need to start using the tools of science to understand them."
How can we design experiments that make computational models disagree? One section of our new @natrevneuro.nature.com Review with @kriegeskorte.bsky.social and @heikoschuett.bsky.social examines studies that used stimulus sets designed to elicit distinct predictions from competing models. 1/16

great to see some places still have a backbone
In case you are an academic who is currently being gaslit into believing that you're a caveman who wants their students to be jobless if you resist allowing AI in your classrooms... I present to you Berkeley Law's response, which can be summarized as "Fuck off directly into the sun."
I also left around the same time. We had something special on Twitter, pre-Musk, but now I reckon there's no excuse for publicly funded scientists to tweet or even peruse twitter.
i did not have half a million followers. but i still left. i miss what science twitter was, but not what X became. like nostalgia about college, or the place you lived when you were 25 -- doesn't exist anymore because the world changed. returning to the place doesn’t resurrect the time or the joy.
Just putting this idea out there: if a theory of cog neuro requires screening out left handed people from experiments, maybe the theory isn't really a theory, yet. (And cool work from this team!)
In honor of International Left-Handers Day, we have an updated preprint on scanning left-handed participants in fMRI studies. Although they're 11% of the population, we routinely screen LH people out of fMRI studies due to concerns about functional lateralization 1/n www.biorxiv.org/content/10.1...
Put this on your journal club roster 🪶🙋😂
Thrilled to see our paper @nathumbehav.nature.com, led by the brilliant (Bsky-less) PhD student Ziliang Xiong from @erc.europa.eu project #TicklishHuman! We asked: -Is human ticklishness shared across cultures? -Can we explain where on the body we are ticklish? 🧵👇 www.nature.com/articles/s41...
An adaptive algorithms that lets you shape your stimulus in any of 50 dimensions according to an observer's response.... and it works almost in realtime so you can use it in experiments on the fly.
New preprint! Have you ever wanted to measure psychometric functions in high-dimensional stimulus spaces, but realised that this is infeasible? We present and validate a technique to adaptively estimate psychometric functions for stimulus spaces up to 50 dimensions. www.biorxiv.org/content/10.6...

Holy shit look at this data science figure. This is an amazing example of communicating a bucket load of highly detailed information in an easy to read and aesthetic format. Also, RIP coal power lol

Illustration has always been fundamental to scientific discovery and record. This is a fascinating discussion with scientist-artists. It's easy to read because the artwork is so beautiful.
Nature interviewed five artists from a variety of backgrounds about how to create engaging images that accurately convey scientific/medical concepts, & how they see the future, in light of AI developments. Insightful nuanced piece, with beautiful visuals from talented real-life human illustrators. 🧪

calling all researchers who collect data from humans 🧠🧪 we are running a very brief survey (<1 min) about jsPsych, the software ecosystem for browser-based data collection. if you use jsPsych, or if you collect data with any other software, please fill it out at tinyurl.com/jspsych-census!

I just gave a short tutorial on what is a spiking neural network and how to train one. From zero to a trained network in one hour. Slides and code you can run in Colab at this repo: github.com/neural-recko... 🤖🧠🧪
For the first and possibly only time in my career did I nail this setting on the first go in PsychToolbox: Screen('BlendFunction', screen.win, GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
