I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.

I will record lectures & all will be found at this link: github.com/rmcelreath/s...

Looks very cool

I remember being kinda freaked out about it and saying I wanted to see more animal testing several years ago. I kinda assumed they'd been done given the work in humans that's been coming out

Oh man...

Learning to bias the activity of a set of neurons in an arbitrary and neutral context isn't the same as controlling all activity over the set of all possible inputs

Spark friends! If you are here at Psychonomics, let’s get together for a casual meet up at Revival Denver Public House on Saturday at 5 pm. Come by if you want to unwind a bit, see familiar faces, and meet others in our community. Pass this along to anyone who might want to join.
revival-denver.com

Upcoming presentations at Psychonomics. We have many super-cool projects on attention and working memory that you don't want to miss! See you in Denver! @psychonomicsociety.bsky.social @xiaojinma.bsky.social @chenyebao.bsky.social @yuezhang-mu.bsky.social @kaitlyndrennan.bsky.social

Lee lab posters at SFN. LL20 on Monday afternoon and OO4 on Tuesday afternoon

Good morning SFN! CoCoA lab posters today and tomorrow afternoon. Come by LL20 to chat with @jacobsellers.bsky.social about using fMRI and our forced response task to examine the dynamics of control

Please come check out our posters Saturday and Sunday! #SfN25 #Neuroskyence

Presenting on contingency representations in PFC during WM on Saturday at SfN! Featuring fMRI and multi-area RNN modeling from my time with John Murray 🤓

And, recruiting a PhD student for Fall ‘26 in my new lab at U-Miami! Check us out here, and feel free to reach out: jam-lab.org (apps due 12/1)

Wouldn't have predicted this. I have some reading to do!

Very solid tips here

My lab at Boston University has open positions for a postdoc and PhD students. We study visual perception, attention, and decision making with a focus on temporal dynamics. Check out our recent work here sites.bu.edu/denisonlab/ and email me if you're interested in learning more

Our amazing department (Psychology) at U-Miami is hiring in their Adult division, with open topic / focus area! Come apply and check out the job ad here: umiami.wd1.myworkdayjobs.com/UMFaculty/jo...:

I am recruiting a postdoc at UC Santa Barbara for an NIH-funded project on the organization of lateral PFC function--across emotion and cognition--using representational fMRI & TMS. I’d love to find someone w/ a background in cognitive control & computational modeling to complement our team! 🏝️ 🧠 🧲

Yup!

Two incredible scientists (and good people)! Couldn't be more thrilled for them! @actlab.bsky.social @monicarosenb.bsky.social

I am accepting a Ph.D. student to begin Fall 2026. The position would be part of the Cognition and Neuroscience program at Mizzou. Great opportunities to learn eye tracking and ERPs. Ideal candidates will have some background in attentional capture and visual search. If interested, please email me!

Neurocomputational mechanisms underlying the distinct motivational influences of reward and punishment on cognitive control Human motivation is fundamentally shaped by one's expectations of the reward they could earn for good performance or the punishment they would avoid for poor performance. However, the extent to which ...

Thrilled to share our new preprint highlighting distinct neurocomputational mechanisms underlying how reward and punishment determine adaptive cognitive control - a massive fMRI study and collaborative team effort with the @shenhavlab.bsky.social 🧠

Policy-Gradient Reinforcement Learning as a General Theory of Practice-Based Motor Skill Learning Mastering any new skill requires extensive practice, but the computational principles underlying this learning are not clearly understood.

We’re all familiar with having to practice a new skill to get better at it, but what really happens during practice? The answer, I propose, is reinforcement learning - specifically policy-gradient reinforcement learning.

White and orange text on a deep red ombre background reads “Black In Neuro Presents Chapters Week October 2025.” Event schedule listed vertically for each day: “Mon 27 – Chapter Roll Call: Share with us on social media about your community and who you can call on using the hashtag #BINTogether. Tue 28 – Community Call: Hear from our Black In Neuro Chapters Committee about how to start or become a member of a BIN chapter. Wed 29 – Manhattan Mixer: Join BINManhattan for a night of networking and career connections designed to inspire, empower, and expand your professional horizons. Thu 30 – SURP Symposium: Support early-career researchers at the inaugural BIN SURP Symposium with professional development workshops, roundtable discussions, and more! Fri 31 – Leaders Retreat with asterisk that denotes retreat is exclusively for our chapter leaders, the Chapters Leaders Retreat is a time to connect, reflect, celebrate, and strategize.” White text at the bottom has registration link and states that any events with asterisk are closed to chapters members only. The Black In Neuro logo featuring a stylized profile illustration is in the top left corner, with soft waveform border accents in the top right and bottom left.

I'm going to die on the hill that tDCS doesn't actually affect the underlying brain area except perhaps indirectly through skin/ peripheral nerve stimulation. I love the anesthetic idea!

Does anodal tDCS over M1 really enhance motor sequence learning? A non-replication of earlier findings in a double-blind, pre-registered large-sample study in humans Background Transcranial direct current stimulation (tDCS) is one of the most widely used noninvasive neuromodulation methods. Despite its popularity, some recent studies highlighted issues about the r...

One of my two last (ever) papers on tDCS:

#JNeurosci: Kashefi et al. dissociate between the “what” and “how” components of motor sequence learning and provides evidence for the development of motoric sequence representations that guide optimal movement execution.

An array of 9 purple discs on a blue background. Figure from Hinnerk Schulz-Hildebrandt.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

From Hinnerk Schulz-Hildebrandt:

The basic pattern shown in this YouGov survey is that people overestimate minorities and underestimate majorities. This basic pattern--overestimating small proportions and underestimating large ones--is due to *psychophysics*.

We argue that a dedicated research program on 'working memory for movements' is long overdue
