Brown psychology professor and social neuroscientist studying the moral side of human behavior

New lab paper out in @NatureHumBehav showing ppl build cognitive maps of social networks to track how information flows. How are these maps built? A replay-like mechanism reshapes them over night😴, making them more abstract, which helps with hardest social navigation problems
How do people track information flow through social networks? New research finds that extended periods of rest, like sleep, help people build abstract cognitive maps for efficient navigation of social networks. @marclluis @orielf @apaxon nature.com/articles/s41562-0…

It's clear that many do not understand what @NIH-funded research does to improve health. It's time to revive a study published 10 years ago that provides incredible information about this. link in the comment Every single new drug approved by the FDA from 2010–2016 was built on NIH-funded research—that’s all 210 drugs. But what the public sees is just the tip of the iceberg. Pharma takes credit for the final product, but beneath each drug developed, there are ~20 years of basic research, and 90% of the cost is from basic research funded by the NIH, which discovers drug targets, understands disease mechanisms, and creates life-saving treatments. Figuring out how cancer evades the immune system, how addiction rewires the brain, and how heart disease develops is the role of the NIH, creating the foundation for the breakthrough drugs that come 20 years later, and the NIH does all that with only 0.8% of the US budget. Without NIH, there would be no cancer immunotherapy, no anti-overdose medication, no anti-heart attack or stroke medication, no cutting-edge treatments. If NIH funding is cut, the iceberg will melt. That means fewer cures, more suffering, and more lives lost. The science beneath the surface keeps us afloat. Invest in NIH. Invest in life

New paper in @BiologicalPsyc1 CNN w/ Amrita & @Franklab_LNCC People can flexibly switch btw resolving policy & epistemic uncertainty (uncertainty about what to do vs about environment) to adaptively learn who can be trusted. But those with anxiety... authors.elsevier.com/a/1jrRu…

...exhibit insensitivity to policy uncertainty and rigid choice policies. This leads to maladaptive behaviors with untrustworthy people. Amrita developed a novel👁️ tracking method that sidesteps issues with existing measures to capture highly granular estimates of uncertainty

Can we use Twitter to track uncertainty in the real world? Latest lab pub led by @marclluis & @DaantjedeBruin measured uncertainty language in more than 20 million tweets during highly uncertain events: Covid-19 2021 US presidential election Jan 6 coup What did we find? 👇

In the case of the 2021 US Capitol attack, moral outrage spikes and uncertainty language abruptly declines, which we track on an hour-by-hour basis. In other words, negative emotion doesn't always increase with greater uncertainty:

The take away: In the real world, it seems like the relationship between uncertainty and emotion may not actually be linear, and is instead more complex than originally thought. Read more here: static1.squarespace.com/stat…

Back for a moment to share our latest paper in @PNASNews! Jae details the mechanism ppl use to build cognitive maps of social networks. Computations abstract over known relationships to infer unknown relationships in network--can explain many behaviors! pnas.org/doi/10.1073/pnas.23…

I usually don’t write political posts on Twitter, but I wanted to clarify a few things about the situation in Israel.

Florida has effectively banned the teaching of AP Psychology. Depriving students of knowledge about the human mind-including mental health / illness, relationships, and the brain-will harm future generations in the name of culture war. Shameful. newsroom.collegeboard.org/st…

⛳ Beyond excited to share our new preprint, in which we show how social biases can be acquired through social learning! (with @B_Lindstroem, @profcikara, and @david_m_amodio). Link: psyarxiv.com/7ec3u 🧵 Key findings below 🧵

Latest lab pub by Amrita Lamba + @NassarLab now out in @eLife! The social world is noisy and complex which means the outcome of a simple interaction could be caused by many different things. How does the brain figure out how to credit the right source? doi.org/10.7554/eLife.84888

Interestingly, learning differences were not driven by stronger prediction errors. Instead, we found that differences in the strength or fidelity of the neural representations drove learning success. 6/
