Long-overdue #BAP2026 appreciation post! I had a BLAST at the BAP @bapsych.bsky.social summer meeting in Birmingham a few weeks ago 🤩🧠💊 enjoyed all the high-quality research presented there, super-stimulating conversations during my poster presentation, and an amazing community (and disco! 🪩)

This study investigates individual differences in the effect of social media likes on posting behavior and their association with and specificity to depressive psychopathology.

New preprint! @martinezlopezp.bsky.social in this systematic review takes a look at the validity & reliability of current tools used for studying habits in the human lab. There are a lot of them! But studies about construct validity were sparse, while reliability analyses were almost nonexistent...

Pablo Martínez-López@martinezlopezp.bsky.social · 2mo ago

Habit research has accumulated many tasks that supposedly tap into the same construct, yet their psychometric properties are rarely examined. Here, we assess their construct validity evidence and analyze their reliability to facilitate interpretation of previous studies and guide novel research ⬇️📝

For many Iranian students, Neuromatch was one of the few bridges to the international neuroscience community. Iranian students and TAs have contributed so much to it. Many of us, including me, found neuroscience through Neuromatch. This decision by Trump’s gov is cruel, unjust and a loss for science

Neuromatch@neuromatch.bsky.social · 3mo ago

We have difficult news to share. Neuromatch's Office of Foreign Assets Control (OFAC) license renewal, which has allowed us to include participants residing in Iran since 2020, has been denied by the United States Government.

To accompany my textbook (Computational Foundations of Cognitive Neuroscience) and the class I taught this semester, I'm open-sourcing my lectures slides: gershmanlab.com/lectures.html I'll continue to update these as I improve them.

Our experiences have countless details, and it can be hard to know which matter. How can we behave effectively in the future when, right now, we don't know what we'll need? Out today in @nathumbehav.nature.com , @marcelomattar.bsky.social and I find that people solve this by using episodic memory.

⚠️ Despite all the hype, chatbots still make terrible doctors. Out today is the largest user study of language models for medical self-diagnosis. We found that chatbots provide inaccurate and inconsistent answers, and that people are better off using online searches or their own judgment.

Your Iranian colleagues are cut off from family back home & are in a state of collective grief, which has many faces. We may appear more aloof or be more impatient, may self-isolate, have more typos, may freeze or overwork to numb the pain, or find fear, memory, or hope in unexpected moments.

This article is now published in @plosone.org. journals.plos.org/plosone/arti... New analysis added: seemingly habitual responses are explained because contingency deg didn't work for some participants (in line with recent outcome dev results in our lab and in @clairegillan.bsky.social lab)
