We just preprinted a huge meta-meta-analysis examining the effects of exercise on cognition, memory, and executive function In short - 2239 effect sizes - extreme between-study heterogeneity - extensive publication bias - some subgroup/exercise-specific effects More below (doi.org/10.31234/osf...)

🚨New Preprint: We develop a novel task that probes counterfactual thinking without using counterfactual language, and that teases apart genuine counterfactual thinking from related forms of thinking. Using this task, we find that the ability for counterfactual thinking emerges around 5 years of age.

The NIH has awarded a $14.2M Director’s Transformative Research Award to a team led by Nobel Prize-winning neuroscientist @ardemp.bskyverified.social, Prof. @liye-tsri.bsky.social and Assoc. Prof. @xinjin.bsky.social to map interoception and build the first atlas of this hidden sixth sense.

🚨 New preprint 🚨 Across 3 experiments (n = 3,285), we found that interacting with sycophantic (or overly agreeable) AI chatbots entrenched attitudes and led to inflated self-perceptions. Yet, people preferred sycophantic chatbots and viewed them as unbiased! osf.io/preprints/ps... Thread 🧵

My friends @foddy.net and @gcuzzillo.bsky.social's game @babystepsgame.bsky.social came out today and it looks amazing. @foddy.net is an artist and philosopher in the truest sense of the words, who just happens to be using video games as his medium at the moment: www.nytimes.com/2025/09/23/a...

love this really elegant paper spearheaded by Linas! one of the clearest instances of resource-rational social cognition i've seen worth a read!

💙New paper!💙 How is knowledge transmitted across generations in a foraging society? With @danielredhead.bsky.social we found: In BaYaka foragers, long-term skills pass in smaller, sparser networks, while short-term food info circulates broadly & reciprocally academic.oup.com/pnasnexus/ar...

In a new paper, my colleagues and I set out to demonstrate how method biases can create spurious findings in relationship science, by using a seemingly meaningless scale (e.g., "My relationship has very good Saturn") to predict relationship outcomes. journals.sagepub.com/doi/10.1177/...

No Evidence of Experimenter Demand Effects in Three Online Psychology Experiments: https://osf.io/g6xhf

We often hear from reviewers: "what about demand effects?" So we developed a method to eliminate them. Something weird happened during testing: We couldn’t detect demand effects in the first place! (1/8)

My website is official 🙌 Excited to share that I am interested in reviewing applications for Harvard’s Clinical Science PhD program this fall as I look for the first student to join my lab! I appreciate it if you can share with your network :) psychology.fas.harvard.edu/people/mark-...

🔥Exciting news in experimental philosophy🔥 Very happy to announce that there will be soon a new journal named “Experimental Philosophy”. It will be open access, free of charge for authors and follow all Open Science principles. Editors and Editorial Board below. More information coming soon...

How far can we trust representation analyses or mechanistic interpretations? Our new work, led by Dan Friedman shows that analyses based on simplifying the model or its representations can be misleading about how the model will behave out of distribution! arxiv.org/abs/2312.03656

Delighted to share this new preprint lead by Arthur Le Pargneux. When somebody needs to "take one for the team" (pull a late night, walk an extra mile, trudge through mud), do people think that moral responsibility falls upon whoever has the weakest bargaining position? osf.io/preprints/ps... 1/2

If you are at #SfN23, go check out the awesome work that Ata Karagoz @atabk.bsky.social is doing with me and Zach Reagh @zreagh.bsky.social! He uses behavioral (!) and neural RSA to measure the construction of cognitive maps for planning.

ICYMI: @steveharoz.com recently made a very nice little feed that curates the most liked psyarix and bioarxiv-neuro preprints over the past week. It is a great way to find new preprints. 🧠🟦 #psychology bsky.app/profile/did:...

An intergroup contact intervention in Nigeria improved intergroup attitudes, fostered more intergroup contact, and decreased feelings of insecurity in these communities, not only for those who directly participated, but also for the wider community! www.pnas.org/doi/10.1073/...

If you know any undergrads who would like to do something very adventurous next summer (experiments on learning in single cell organisms), have them get in touch with me.

New economics reproducibility project is seeking collaborators to conduct reproduction and robustness tests of published development economics findings. Contributors earn 2500 euros and co-authorship on the overall project paper. Details: www.rwi-essen.de/fileadmin/us...

Our new R package makes it easy to report the percentage of effect sizes that a given effect is larger than for a given research field. So instead of reporting a 'medium' effect, you can say something like, "we found an effect that was larger than 42% of effect sizes reported in the field"

Learning to Imagine: The Science of Discovering New Possibilities (www.amazon.com/Learning-Ima...) is coming out Nov. 14!   To celebrate, I will be posting an image and caption from each chapter over the next several days. Here’s the table of contents to start things off.

A good time of year to repost: Every year I read a lot of grad school applications from accomplished people that don't give me the info I'm looking for. It feels like a major hidden curriculum thing. So here's (my opinion on) how to write a great Statement of Purpose/Research for a PhD program. 1/

Hi Bluesky! I’m recruiting PhD students to help launch the Exploration, Learning, and Mind Lab at U of New Hampshire Psych in Fall 2024! Check out our lab website at liquinlab.github.io for more info, and feel free to get in touch if you’re interested in applying! #CogSci #DevPsych #PsychSciSky

Solid evidence now exists to show that implicit bias responds to a variety of outputs (including propositional ones) and is capable of long-term change. In this commentary with @ericman.bsky.social, we consider the implications of these findings for our science and for society: rdcu.be/doFRI.

A common view in behavioral science is that people cannot introspect directly on the mental processes underlying their choices. Here, in a new preprint, we provide evidence that they can. osf.io/preprints/ps... Work with Ryan Carlson, Hedy Kober, and @mjcrockett.bsky.social

As my first post, delighted to share our #neurips2023 paper: Evaluating Cognitive Maps & Planning in LLMs with CogEval We test cognitive maps & planning in 8 LLMs. Failures like hallucinating invalid paths & falling in loops suggest no emergent zero-shot planning. 1/n 🧵 arxiv.org/abs/2309.15129

Open data sharing is a good thing; Protecting participant privacy is a good thing. Sometimes these two good things are in conflict. Our new preprint introduces a decision-making framework and open source tools to help share as openly as possible and as closed as necessary. osf.io/preprints/me...
