Programming tip: never type out a 10-character command when you could instead press the up arrow for 5 minutes until you find that command in your history

Puzzled that an #lme4 model that didn't converge before now reported no issues, I found that as of lme4 1.1-38, "derivative-based convergence checks are now skipped for models with large data". I can't find any more information - what's best practice here? Assume the model is "fine"? 1/3 #rstats

Incredibly proud to be a part of ManyBeds, a multi lab replication effort of targeted memory reactivation during sleep, which was just honoured with a SIPS commendation! I'm very excited about what will come out of this (and then never shut up about it).

Interested in human replay and solid methods? Jointly with @skjerns.de we're releasing a benchmark dataset with known ground-truth neural sequences in MEG & fMRI, for developing & validating replay methods. First test: existing methods show similar effect sizes, but room to improve shorturl.at/6TgIr

FASTIMAGES: Validating replay detection methods in human neuroimaging using a combined MEG and fMRI dataset

Studies in rodents and humans using invasive electrophysiology have established that neural replay is a ubiquitous phenomenon in the brain that is associated with a wide range of cognitive functions, ...

I think about this figure from @stephensenn.bsky.social's Statistical Issues in Drug Development a lot (Ch. 7) alot. A useful reminder that baseline adjustment is often about precision not just “controlling for confounding.” #StatsSky #Statistics #EpiSky

That was an awesome talk! Relieved to see there's people (passionately!) tackling these issues, even if there's loads of work to be done yet...

#PuG2026 in Heidelberg started with the ECRs meeting on the topic of power and abuse of power in German academia by Andrea Kübler. Kudos to the ECRs representatives for raising awareness on such relevant and sensitive issue!

Rare opportunity to hear me speak less than 5 minutes about my research!

bioDGPS and DGPA@biodgps-dgpa.bsky.social · 2mo ago

The #PuG2026 is taking place in Heidelberg this week! We are very excited about the exceptional lineup of speakers in the symposia and poster sessions and want to draw your special attention to the #Posterblitz organised by the ERCs taking place on Friday from 2 to 3:30 PM in HS13! ⚡

It's that time of the year: IGOR is going to #PuG2026 in Heidelberg! 🧠 Interested in open and reproducible science? Come meet us, discover our latest work, and get involved. 🧵 Check the thread below for all our events #PuG2026 #IGOR [1/6]

Biopsych Community, we are ready and can‘t wait to welcome you to Heidelberg! #PUG2026

7/ There is also an important caution. Human-only teams found more major coding errors than AI-assisted teams. So even when AI assistance preserved reproduction success, it did not clearly improve the harder work of finding consequential problems in code and data.

Now out in Nature Neuroscience: "Fixation duration on natural scenes is explained by memory encoding not processing demand". www.nature.com/articles/s41... Our eyes don't linger because recognition is hard; they linger to remember. Let me take you on a quick tour. 🧵

Fixation duration on natural scenes is explained by memory encoding not processing demand - Nature Neuroscience

By combining magnetoencephalography and eye tracking, this study sheds light on why people fixate on some parts of natural scenes longer than others. Rather than visual complexity, fixation durations ...

You: please act normal you need these people to like you Me: ok! People: hi Me: Did you know that while horses originally evolved in North America, they went extinct during the pleistocene ~12,000 years ago, and were only reintroduced by the Spanish colonists.

You: please act normal you need these people to like you Me: ok! People: hi Me: Did you know that John Snow did not draw his famous cholera map during the 1854 Soho outbreak itself, but in the months afterwards to help explain his water transmission theory to colleagues and the wider world.

The pep talk I will be giving myself before my defense.

"Never hallucinate or make anything up." yes, you can just demand that the LLM not make errors that's definitely how the technology works

Fresh preprint! Reward Signals Drive Encoding of Reward-Item Associations During Motivated Learning osf.io/preprints/ps... We present evidence that mesolimbic activity during motivated encoding reflects source memory for rewards, which later guides goal-directed retrieval. 1/12

Don't be shy to take on a little two-week side project. These five months will be the most precious three years of your academic journey.

Is there a way to "soft mute" accounts on Bluesky? Like, I don't want some users to COMPLETELY disappear from my feed, but I would like to adjust the ratio of content a bit. Right now, I see more of people who post/reply more, which is not a good metric. How do you guys optimize your feeds?

Whoever will get the job: I'm already interested in your work!

Can we really measure replay in humans using MEG with current methods? In our most recent paper we simulated replay under realistic conditions via a novel hybrid approach with astonishing results. we're delighted that it has now been published @elife.bsky.social! elifesciences.org/articles/108...

How sensitive is TDLM really? Can we actually find replay when we know it is present?

Guys, guys, guys. Can you please stop dropping extremely cool stuff on April 1st? It makes me very anxious that I will get rickrolled or sth if I click on it. (To clarify: You won't get rickrolled with this one, you just receive an awesome Zotero plugin that checks for replications!)

Lukas Röseler@aufdroeseler.bsky.social · 4mo ago

Download our free and open source Zotero Replication Checker plug in at forrt.org/flora_zotero. Check entire libraries or single reports, add replications and original studies, have them linked and labelled, and get regular updates - all with privacy-preserving matching.

This is why sharing data and code (and having both reviewed!) is important!

Brian Nosek@briannosek.bsky.social · 4mo ago

For reproducibility, we could obtain data for only 24% of 600 papers. Of the 143 papers assessed, we precisely reproduced 54%, approximately reproduced 74%. We were much more likely to succeed if authors shared data and code, versus just data or if we had to reconstruct data from original sources.

I have a decent amount of patience. I can complete any souls-like game with a smile on my face. But there are online proofing systems out there that just make me wanna punch a wall.
