Very interesting paper framing decision biases as habit-like choice repetitions. I wonder if any element of non reinforced preference change (www.sciencedirect.com/science/arti...) is at work here.

Methylphenidate and drug memory modulation normalizes brain function in drug addiction Individuals with cocaine use disorder underwent a brain imaging task designed to weaken drug memories by extinguishing reactivity to images that were previously associated with drug use. When methylph...

Unintended bias in the pursuit of collinearity solutions in fMRI analysis Abstract. In task functional magnetic resonance imaging (fMRI), collinearity between task regressors in time series models may impact power. When collinearity is identified after data collection, rese...

Our new paper is out! It offers a tool to assess collinearity impact on contrast estimates
*and*
uses simulations + MID data to show how common collinearity avoidance strategies can bias results.

New paper out in cognition with @arikahn.bsky.social, @nathanieldaw.bsky.social, Cate Hartley, and @katenuss.bsky.social !!

We show that children 👶 use predictive representations (e.g. SR) to guide their choices, providing an account of how they can make flexible choices in a changing world

I love this figure which both echoes and undermines the famous figure from Schultz et al. (1997).

Motivation as Neural Context for Adaptive Learning and Memory Formation Our memories shape our perception of the world and guide adaptive behavior. Rather than a veridical record of experiences, memory is selective. An accumulating body of work suggests that motivational ...

Motivations are like emotions about (what we know about) possible outcomes. Sometimes incentives spur urgency to act, other times to comprehend. Neuromodulatory systems reflect these motivational moods and shape memories. Out now w @jiahou-poh.bsky.social!

I’m looking for a postdoc to join me at UCSD, ideally a clinical psychologist PhD who can deliver mindfulness interventions as well as write papers and do analyses. I have one of the world’s largest psychophysiology datasets of opioid misuse, OUD, & chronic pain. Competitive salary. DM or email.

This will change everything!

Finally, neuroscientists have discovered a pill to treat their craving for simple brain explanations. It's very effective, provided it's taken daily, but no one knows how or why.

Ok, reinforcement learning fans: RL is great, but what do we do when there's no obvious reward from the environment? What about perfecting a golf swing or a foxtrot or a musical performance? We may have an answer. A tale of 🐦 🎶 + 🧠. 🧵1/ #bioacoustics #prattle 💬 #neuroai #compneuro

In an MRI study with 45 participants using deep-learning models, hippocampal activity was predictive of experiential choices, such as choosing a song to listen to. For choices involving risk, the ventral striatum and insula were active. In PNAS: www.pnas.org/doi/10.1073/...
