New preprint:
Neural manifolds that orchestrate walking and stopping
Here we develop a new theory for neural generation of walking and how it can stop- Next we test the theory using Neuropixels probes in the lumber spinal cord of freely moving rats. See more:

Abstract. Nonhuman primate studies traditionally use two or three animals. We previously used standard statistics to argue for using either one animal, for an inference about that sample, or five or m...

We’ve come to accept the 45-minute data dump: a PI sprinting through dozens of studies to prove how much they’ve done. I’d rather hear one clear question followed to its end than a career retrospective pretending to be a talk.

This is why you should pair code in an IDE and implement modular unit tests as you go. Asking the AI to dream up an entire pipeline will result in disaster. @russpoldrack.org has a great new book on how to do this well.
It's like LLMs in the past few months realized that little reprexes are cool, but people aren't realizing that and just going with the fake code. Can't wait for this to inevitably make it into published stuff.
Newest LLM tell/quirk in coding assignments this semester: instead of generating code based on the CSVs that I provide, LLMs have been inventing datasets with rnorm() and sample() (and an obligatory set.seed(42)) and then making plots with the fake data.
I'm so tired.

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/ >
But here's, the thing, p values and significance become useless at such large sample sizes. When you're dividing the coefficient by the SE and the sample size is in the tens of thousands, EVERYTHING IS SIGNIFICANT. All you're testing is whether the coefficient is different than zero.
