Anyone want to do a PhD with me at the Sunny Coast? I'm recruiting, and I wanna do some fun psychophysics (but the possibilities for the PhD are very broad). Domestic students only, sadly.

In case y'all happen to know someone:

I made a map of 3.4 million Bluesky users - see if you can find yourself!

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

Imagery modulates the pupillary response, but this does not reliably index differences in imagery vividness.
Most people report that they can imagine seeing things in their mind’s eye. But there are large individual differences. A small proportion of people r…

Really cool. I wonder if the spatial extent of the sweeps is related to the speed of movement?
Whether the system can be flexibly redirected to prioritize specific locations has been unclear. Using large-scale #Neuropixels recordings in freely behaving rats, we find that both sweeps – and the internal direction signals driving them – are dynamically modulated moment by moment. (4/6)

The tech that enables Grok to make sexualised images against peoples' will is here to stay and we're just going to have to bring it into the classroom and ensure that all our students are genporn literate as they enter the marketplace.

A dynamic spatiotemporal normalization model captures perceptual and neural effects of spatial and temporal context
The effects of spatial and temporal context on sensory systems have mostly been studied independently of each other. This study shows that the modulation of visual perception and neural activity by th...

The idea to use a bot (probably) to write about the idea that we could be running out of new ideas is itself a new idea, thereby proving that we are not, in fact, running out of new ideas.
This column on Vox is the biggest pile of steaming AI crap I've seen this year. Human's aren't running out of ideas. Instead, those with power and money don't want to listen to ideas that threaten their power and money.

Ideas are plentiful. Putting those ideas into action is the hard part.
We’re running out of good ideas. AI might be how we find new ones.
What if the best use of AI is restarting the world’s idea machine?

There is money just sitting on the table for a university brave enough to grab it.
The first school to market itself as AI free is going to corner the market on people interested in actually learning. And I would not be surprised if rich families and the children of people creating this tech were the first movers.
My employer, Dartmouth College, today boasts it's 1st Ivy "to launch AI at an institutional scale." It is doing this by partnering--"more than a collaboration"--with Anthropic, a company that stole the books of many faculty, me included, which many of us are suing.

Do you have an open working memory dataset and want it to be findable and reused? You can now add it to the Open WM Data Hub: williamngiam.github.io/OpenWMData! The collection of datasets tagged with useful metadata is steadily growing thanks to a small team of volunteers!

New pre-print with @drbarner.bsky.social! We ask how children come to understand age. We find that young children use numerical age and facial morphology to identify who’s older, not just size, and point to acquiring a number system as key to developing an understanding of age.

My Visual Attention in Crisis paper has finally appeared, along with 30 commentaries and response. I argue that it’s time to rethink attention from the ground up, and suggest key phenomena and possible directions. Requires access, alas. doi.org/10.1017/S014...

Great thread and I wanna throw in my two cents too: increasing N does not increase the chance of a false positive per se (theoretically it'll always be alpha).

However, increasing N, particularly with lots of DVs, makes very small confounds more likely to produce a statistically significant result.
There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >
