🚨 New publication 🚨

Excited to share this new forum piece led by @kevinetiede.bsky.social

We propose broadening risk communication to cover neglected dimensions outlined in our risk-information taxonomy, requiring greater reliance on simulated experiences.

Machine+Behavior Conference Welcome to the forefront of behavioral science in the digital age.

Submit your abstract by 11 February 2026 (AOE): machinebehavior.science/behavioral-c...

The workshop focuses on machines trained to replicate human behavior, as scientific models of human cognition and action, as tools for large-scale behavioral simulation, and as objects of study in their own right. We invite talks, lightning talks, and posters.

🚨 Deadline extension 🚨

BEHAVIORAL CLONES WORKSHOP

Imitating humans is a powerful route to machine behavior and an emerging lens on human cognition and social simulation.

🗓 Fri, 20 May 2026
📍 Following Machine+Behavior @ Max Planck Berlin
🗣️ Invited talks: Danica Dillion, Raja Marjieh, Marcel Binz

🚨 7 days left to submit your work!

We further demonstrate an important moderating role of embedding extraction method and confirm results suggesting that final-layer embeddings underrepresent psycholinguistic information.

We show that accessibility cascades from lexical to semantic information similarly across all transformer language models, but is still realized differently in encoder and decoder models.

🚨 New preprint 🚨

Excited to share new work led by @tikhomirova.bsky.social, presenting a large-scale evaluation of the accessibility of psycholinguistic information in transformer language models.

🚨 New preprint 🚨

We present the decisions-from-experience database (DfE-DB), including data from 168 studies.

The data are currently shared with the original authors and made public upon publication.

I am hiring a postdoc for a DFF-funded project on social influence, and the decision processes that fuel rich-get-richer dynamics in the online/offline world. The position is for up to a year, competitive Danish salary, remote work possible. Interested or know somebody? DM me or share!

I am sorry to hear. If you are interested, there is research showing the usefulness of LLMs for psychological research, which in part derives from the models' ingestion of academic literature during training. I see no reason why LLM capabilities wouldn't generalize to this context to some extent.

I think I grasped your point. But all good, no problem if we disagree.

Logically correct---not quite what I said. I genuinely think that LLMs can provide useful signals on such questions. But we need to do our best to assess error and bias, like we should do with every other approach used to address such questions.

The ratings should be validated, of course. But there are good reasons LLMs might "know" this up to some reasonable error and bias.

🔬 How has psychology contributed to achieving the 🇺🇳 SDGs?

Our new preprint maps 230,000 psychology articles to the SDGs using our text2sdg R package (www.text2sdg.io) and analyzes historical trends in topics, national and gendered contributions, and citation patterns.

@cos.io, I noticed that, since the relaunch, PsyArXiv preprints are no longer being indexed by Google Scholar. Do you know if this will be fixed? Thank you for your work!

How can LLMs advance the cognitive sciences?

@ruimata.bsky.social and I put together a review on how LLMs can help us address five long-standing problems in cognitive science (e.g., disciplinary silos or lack of generalizability).

🚨 New preprint 🚨

Are reinforcement learning models complete accounts of decisions from experience if they ignore explicit memory?

In this new preprint, we show that people indeed form robust explicit memory representations that flexibly guide later decisions.

🚨 New publication: How to improve conceptual clarity in psychological science?

Thrilled to see this article with @ruimata.bsky.social out. We discuss how LLMs can be leveraged to map, clarify, and generate psychological measures and constructs.
