#Neuroimaging crowd, hear me out! 👀 Did you ever want to add #EyeTracking to your #fMRI study but found it too much hassle? Got existing data you’d love to add eye tracking to? Try out *MR-based eye tracking* (i.e. inferring gaze from eye voxels)! A few options below!🧵👇 1/9

1/ A century ago, Tolman showed that meaningful learning can occur even without apparent performance improvements. What is the neural basis of this distinction between learning something vs learning to perform? We tackle this in a new manuscript 🔥 🐭🔬📰 https://t.co/DXQHjNRSpR

We append to the body of work formalizing 'momentum' as an integrative signal that facilitates persistence in mental states. Special nods to 'Psychological momentum' by @chrishoney, @amahabal @buddhikabellana, and 'Mood as momentum' by @eraneldar, @RobbRutledge, @yael_niv
📢 Preprint alert! How do humans maintain sustained drive toward distant and persistent goals? In our preprint, we introduce 'momentum' toward a setpoint as a computational concept driving persistence in long-term goals. (1/13) https://t.co/SHN2xkDMhM

Apes remember past groupmates for decades! Check out our latest work, just published in @PNASNews with @LauraSimoneLew, @northernlimitpt, @fkano, @Jeronobo1, and Josep Call Video Summary: https://t.co/XyFGdCI8Mi Paper: https://t.co/ms7CTrnJ9v
I am thrilled to finally share these results with the world! We found that chimps and bonobos likely remember familiar conspecifics whom they haven't seen in years -- possibly as long as 26 years. It's the longest memory ever recorded in nonhuman animals.

new pre-print: "Reverse engineering the self" (by L.A. Paul, me, Julian De Freitas @JulianDeFreitas, and Josh Tenenbaum) In which we combine philosophy, cog-sci & CS to propose a framework for reverse-engineering an agent that can “think for itself” https://t.co/qXvgHrDap3

1/n Excited to share our work on Understanding Social Reasoning in LMs w/ LMs! We present a new framework for procedurally generating evals for LMs by populating abstract causal templates! We generate a scalable theory of mind eval, BigToM, w/ 25 conditions & 5k LM written evals!

Excited to share this new work from the lab! Our first foray into human learning experiments. Read @aaronwang_23 tweeprint to learn more about how humans learn without instructions in a simple task (it may surprise you!) Just a few words about the team that made this happen (1/5)
Think of the last time you learned something new. Did you learn from someone else? Could you have learned it on your own? In this preprint, we ask how humans learn in different environments—from getting full instructions to almost no instructions at all!

Pungor et al. use calcium imaging to measure visually evoked response properties in the cephalopod central nervous system. They demonstrate shared and novel aspects of visual function in the octopus,...
Very excited to share our new preprint on visual processing in the octopus! Led by Judit Pungor @traceofpink, together with @jsongco_ and @climbing_octo, we measured the functional organization of visual responses in the octopus brain. 🐙👁️ https://t.co/J99W57NoOl 1/n

🧵A lot of current AI is obsessed with recognizing emotions from facial expressions — but that’s not how humans do it. Humans make systematic, nuanced predictions of emotions people *will* experience, without ever seeing a face. Paper👇w @DaeHoulihan
