"PsychOpen GOLD to be discontinued at the end of 2027" psychopen.eu ...less journals that offer Diamond Open Access 😞

TeaP 2027 (Tagung experimentell arbeitender Psycholog:innen /Conference of experimental psychologists) Mannheim, Germany 21-24 March 2027 Contributions welcome from all topics in Experimental Psychology and neighbouring fields using the experimental method.

Congratulations to the project “openESM,” which received🏆2026 SIPS commendation! openESM is a database of harmonized openly available experience sampling datasets. 🔗Project website: buff.ly/3Q5EwYt 🔗A preprint describing the project: buff.ly/iXcT6ZL

AI in scientific publishing: Slower, worse, and more expensive | Science www.science.org/doi/10.1126/... Claude's comment on the title: "Turns out you can automate everything about publishing except the part that made it worth doing." 🤫

New website is live, including a new blog post :). I respond to the call by @psychscience.bsky.social asking how we can improve APS conferences. eiko-fried.com/blog/in-pers...

At the end of the term I asked my college creative wriing students to submit anonymous thoughts on AI. No real surprises: Mood ranges from resignation to despair, capitulation from embittered erosion of standards to total, feelings of betrayal from deep to furious. 1/

One more week to apply for the postdoc position 🙂 uni-marburg.de/78NrWT

Wichtigste Änderung neben dem Nichts, was letztlich drinsteht: Die Übernahme der nicht genutzten Zeiten in die Postdoc-Phase entfällt. Wer also unter sechs Jahre Befristung vor Abschluss der Promotion hatte, bekommt sie danach nicht mehr. #IchBinHanna #WissZeitVG

New preprint together with @timangelike.bsky.social: Evaluating Large Language Models for Feature Extraction from Verbal Stimuli: A Simulation-Based Workflow We draw on generalizability theory and the ADEMP-template for simulation studies to assess the multiverse of prompt decisions. osf.io/xphm9

Email: "anbei senden wir Ihnen Ihre Biographie für den Europäischen Gelehrtenkalender. Wir wären Ihnen dankbar, wenn Sie uns etwaige Korrekturen mitteilen könnten." Kleingedrucktes im PDF: "Eintragungspreis Euro 369,-. Durch Rücksendung dieser bestätigten Textvorlage kommt ein Vertrag zustande."😮

"What follows are the five horsemen of the significance apocalypse [...] To the truly free-spirited researcher, they are a coordinated assault on productivity, publishability, and the ancient scholarly right to discover one’s hypotheses only after the data have had a proper chance to speak." 😅

Great quote by Cronbach, Gleser & Nanda (1972): "The tidy theory of error laid down for psychology at the start of the century by Spearman and Brown has always seemed just a little too tidy to describe the perverse behavior of real data." 😅

Am Samstag in Marburg 👏🏼

💭 Come work with me, Mark Hoogendoorn, and Dimitris Rizopoulos! We are offering a 3 year PostDoc to do research on the intersection of machine learning (ML) and statistics. 🔢 💫 You will be part of the Stress in Action consortium: stress-in-action.nl/science-of-s... Vacancy: lnkd.in/ewN5T6AA

Does it make sense to preregister simulation studies? This question has sparked a lot of debate. ▶️We* work through the why, when, and how ▶️We discuss different phases of methodological research to clarify where preregistration might (or might not) add value 📝 Preprint: doi.org/10.31234/osf...

Finally published in Memory & Cognition: Multinomial models of the repetition-based truth effect: Investigating the role of prior knowledge link.springer.com/article/10.3...

Interesting postdoc position on modeling psychological resilience at the DKFZ Hector Cancer Institute, Mannheim: jobs.dkfz.de/en/jobs/1682... --> dynamic/latent-variable models, Bayesian hierarchical models, causal inference, time-series analysis, cognitive modelling

The latest version of Sigmund, the #AI #research assistant, is able to fully control the #OpenSesame interface. This allows you to build #psychology experiments entirely through conversation. This is no AI slop, but real functionality with real benefits! Tutorial 👉 osdoc.cogsci.nl/4.1/tutorial...

Halloween in our lab 🎃 Beware of divergent transitions!

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/ >

Simulation studies have a conflict of interest problem. The same team: - develops a new method - designs a simulation study to evaluate it However, the new method has to show good performance to get published. We propose living synthetic benchmarks to address the issue (doi.org/10.48550/arX...).

Welcome to @lauragroot.bsky.social as a new member in the Psychological Methods Lab at @unimarburg.bsky.social! 🎉 Laura just started as a PhD student and will work on Bayesian statistics and multinomial processing tree (MPT) modeling.

We built the openESM database: ▶️60 openly available experience sampling datasets (16K+ participants, 740K+ obs.) in one place ▶️Harmonized (meta-)data, fully open-source software ▶️Filter & search all data, simply download via R/Python Find out more: 🌐 openesmdata.org 📝 doi.org/10.31234/osf...

Welcome to @timangelike.bsky.social as a new member of our lab at @unimarburg.bsky.social! 🎉 Tim just started as a postdoc in a Momentum project funded by @volkswagenstiftung.de: "Bridging the Gap Between Verbal Psychological Theories and Formal Statistical Modeling with Large Language Models"

Konservative 🤝Rechtsextreme = politischer Selbstmord? In vielen EU-Ländern versuchen konservative Parteien durch Kooperationen, rechtsextreme Parteien zu „zähmen“. Die CDU-nahe Konrad-Adenauer-Stiftung hat untersucht, was das für Konsequenzen hat. Spoiler: Es funktioniert nicht. 1/6🧵

For all who use Bayesian hierarchical models, have a look at our new preprint, out now together with @linushof.bsky.social @nunobusch.bsky.social and @thorstenpachur.bsky.social osf.io/preprints/ps...

New paper showing that both the test–retest stability and the split-half reliability of the repetition-based truth effect is close to zero: www.sciencedirect.com/science/arti...

At the FORRT Replication Hub, our mission is to support researchers who want to replicate previous findings. We have now published a big new component with which we want to fulfill this mission: An open access handbook for reproduction and replication studies: forrt.org/replication_...

Help us show there is support for offering registered reports at one of Psychology's leading method's journal! chng.it/TwwnVBScVb

Reading this and trying to take in the full enormity of what is happening. The scale of it. open.substack.com/pub/christin...

1/3 I think the premise is worth some attention: why is there a (frequently wrong) expectation that science is precise? I am often confused even by textbooks for university student audiences. Confused about how frequently findings and expert judgements are portrayed as certain and final.

"Science is expected to be precise, and admissions of uncertainty (especially large levels) can be perceived as scientific failures, rather than natural limitations of knowledge of a topic." 😕 Broomell et al. (2025). Expert judgment and communication of uncertainty. doi.org/10.1007/978-...

Just submitted a minor bugfix of RRreg to CRAN: github.com/danheck/RRre... The R package focuses on analyzing univariate & multivariate data collected with the Randomized Response Technique (RRT), which protects anonymity in surveys by randomly scrambling responses. I also added a new logo 🚀
