A key challenge for computational psychiatry is to distinguish state from trait markers and go beyond cross-sectional studies. Here we show that as paranoia waxes and wanes in patients with schizophrenia, so too do volatility priors

Individuals with schizophrenia spectrum disorders expect greater volatility in the world, and this cognitive bias is linked to paranoia and delusion severity over time.

happy birthday to meeee

I know you are but what am I?

Excited to share our new paper on reward identity and goal-directed decisions in @plosbiology.org. plos.io/3R9rIxZ Normally, I would write a quick thread 🧵on the results but @joeycharbonneau.bsky.social & @erinlrich.bsky.social already wrote amazing primer! Read it here: bit.ly/4vWIn6W

Preprint alert! 🚀 Spontaneous eye blinks are often treated as EEG artefacts. We show they can serve as temporal markers of internal attention, aligning with moments of attentional focusing in working memory. Check it out:

Spontaneous eye blinks as temporal markers of internal attention

Eye blinks are among the largest physiological artefacts in electroencephalography and are typically removed from the recordings. Yet their timing may carry information about cognition. Here, we asked...

The NYU department of psychology is also reinstating the GRE as a requirement for PHD admissions. I heard Yale and Harvard are as well. Now Penn too. If you are applying to psych PHD programs this year be sure to take the exam.

Timing, movement, and reward contributions to prefrontal and striatal ramping activity

Across species, prefrontal and striatal neurons exhibit time-dependent ramping activity, defined as a consistent monotonic change in firing rate across temporal intervals. However, it is unclear if ra...

📢New paper out today in @cognitionjournal.bsky.social! Does the value of an unchosen option — inferred through counterfactual reasoning — spread to related items in memory, similar to how the value of a chosen option — acquired through direct experience — does? In short, yes!

The inferred value of unchosen options spreads to related items in memory

Counterfactual thinking — considering what could have come of choosing the other path — can facilitate inference. Previous studies have demonstrated t…

2025: - 1st 1st & corresponding author paper out - interviews x expts x 1st trimester hell - invited talk to NIH IC director’s lab - defended PhD at 30 weeks to zoom party - began dream postdoc at 35 weeks - gave birth at 38 weeks - 3 months paid leave thank you for the great year, everyone.
