🚨 New preprint alert! 🚨 Transdiagnostic latent factor models of psychopathology are widely assumed to improve brain-behaviour associations. So we decided to test this directly and found that they don't. A short 🧡

New preprint from the lab! Led by @martingell.bsky.social .

There is something for everyone: brain-behavior prediction, latent variable modeling, test-retest reliability. πŸ§ πŸ“ˆπŸ“Š

Dopamine Supports Reward Prediction to Shape Reward-Pursuit Strategy Reward predictions not only promote reward pursuit, they also shape how reward is pursed. Such predictions are supported by environmental cues that signal reward availability and probability. Such cue...

Out today, Melissa Malvaez, Nick Griffin, Andrea Suarez & team discovered that dopamine can enable reward predictions to shape how we pursue reward.

Surprisingly, we find that dopamine can constrain instrumental reward seeking.

Haha, well, my running speed is basically a walking speed but the new temp achieved means I can get out more in winter than I thought which is awesome!!!

I’ve got a list too……only willing to share the highlight reel right now: I went for a run in 35 degrees, which I didn’t know I could do!! And I’ve got an idea I’m in love with….but now to turn it into something…

#eNeuro: Findings in rats from Boven et al. reveal that the cerebellum doesn't just fine-tune our movements but can also actively compute our internal sense of time, helping link between what we perceive and how we act. https://doi.org/10.1523/ENEURO.0198-25.2025

OK I swear a saw a cartoon about a mediation analysis being 3 correlations in a trench coat but I can't find it

and searching online just gives me a lot of trench coats πŸ˜‚

does anyone have this? @dingdingpeng.the100.ci in my mind you were involved but I might have made it up

Stand With Minnesota Stand With Minnesota is a hub for supporting, learning, and taking action to support Minnesotans impacted by ICE and federal enforcement.

Rent assistance is a HUGE need right now. People have drained their savings in hiding for months and now they’re losing their homes too.

If you need ideas about where to send your money:

Prefrontal neural geometry of learned cues guides motivated behaviours - Nature The dorsomedial prefrontal cortex encodes the value, salience and valence of learned stimuli along distinct neural dimensions, and the geometry of these representations shapes motivated behaviours in ...

Can you easily distinguish between value, valence, and salience?

Probably not, but the prefrontal cortex of mice seems to achieve this by creating a sort of multidimensional orthogonal neural space, where each dimension corresponds to one of these subjective elements

So excited that this textbook, edited by @dfareri.bsky.social @dvsmith.bsky.social & @thepsychologist.bsky.social is out now! And so happy to have been invited to contribute. Here’s my chapter on the role of memory, esp. semantic memory, in temporal discounting: link.springer.com/chapter/10.1...

in an ideal world the trauma this couple went through *shouldnt* resonate stronger than a latino family terrorized by ice. but we dont live in that world. we live in the real world. so i applaud it when the most minnesota people possible link arms with us and FIGHT like this.

How many versions of the Iowa Gambling Task (IGT) exist? And how much does this affect research using the IGT? More than you might think. 🧡

The Iowa Gambling Task is an extreme example of Jingle Fallacy and schmeasurement.

In 100 articles we found 244 different ways of scoring it, 177 were never reused. Correlations between them range -.99 to .99.

At the same time, we show meta-analyses combine these results as if they’re equivalent.

NIH grant writing people, do you have thoughts on the use of "I statements" in F fellowships and K training grant apps?

I thought someone told me once to use "I will", "I propose" in training-focused apps to emphasize independence, but maybe it sounds arrogant?

Why in the world are we not screening all pregnant people for iron deficiency when we know it’s associated w/ bad outcomes for mom & baby, affects the vast majority of pregnancies & is easily diagnosed & treated?!

Oh I forgot.

We don’t care about women or children.
