My review on the "Confidence-accuracy dissociations in perceptual decision making" is now published. I think that this will be useful to both experts and newcomers to the field.

Novelty is not just about whats new, but also what feels new given past experience. New study from Sophia Becker in Wulfram Gerstner’s @epfl-brainmind.bsky.social lab posits a model showing how similarity between familiar and novel stimuli shapes exploration and learning - doi.org/10.1016/j.ne...

There is substantial variation across people in navigation ability, which is shaped by multiple factors. A Review in Nature Reviews Psychology organizes these factors and discusses the cognitive and neural mechanisms of their influences on navigation. 🔒

Neural correlates of subjective sleep depth and subjective sleepiness. Scalp topographies illustrate the results of GLME models assessing the relationship between EEG activity (delta power, gamma power, and gamma/delta ratio) and subjective sleep depth (top half) or subjective sleepiness (bottom half). The top rows show the main effects of each brain activity index; the bottom rows show the interaction between brain activity and conscious experience (CE+CEWR vs. NCE). Significant interaction effects were found for subjective sleep depth but not sleepiness.
Perceived #sleep depth is generally thought to reflect reduced brain activity. @giuliobernardi.bsky.social &co show this relationship weakens during #dreaming, suggesting that dreaming helps sustain the subjective experience of deep sleep @spacelabimt.bsky.social @plosbiology.org 🧪 plos.io/4v8OxkH
New preprint!🚨
How do people learn how to search the visual world?
Across 3 experiments, @chrisahn.bsky.social and I show that abstract environmental statistics shape visual strategy selection, but asymmetrically. People readily lean into bottom-up salience, but only override it when they have to.
In a new preprint, we use a combination of 2AFC and discrimination tasks to quantify sensory, decisional, and metacognitive noise in units of the physical stimulus. We find that, across two experiments, sensory and decisional noise are comparable, while meta noise is lower.

How do the brain’s event representations change as we gain familiarity with an experience?
Brain regions’ representations can become coarser or finer as events become familiar. Slow-timescale structure predicts memory.
Excited to share this work w/ Narjes Al-Zahli & @chrisbaldassano.bsky.social!
Attention fluctuates over time and across contexts—how is this reflected in the brain?🧠 Fitting a dynamical systems model to fMRI data, we show that the geometry of neural dynamics along the attractor landscape reflects changes in attention. Out in @natcomms.nature.com

New lab paper! 🧠
Human hippocampal & MTL theta activity is linked to eye movements, but only during memory-guided navigation. Theta is also strongest during longer, more exploratory eye movements.

Huge congrats to Humza & team! 👏
Anxiety is associated with increased generalisation of threat to similar stimuli. This paper dissociates perceptual mistakes from value generalisation and links stronger value-transfer to trait anxiety.

Really neat work by Fountas and colleagues at UCL:
arxiv.org/abs/2603.04688
They propose that consolidation reflects a form of "predictive forgetting" that aids generalization.

New paper from the lab in which we test whether DDM and confidence distributions can be used to distinguish between perceptual and decisional effects. We show that putative signatures of perceptual effects emerge in a purely cognitive task.

📢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!

What if the relationship between smartphone use and mental health depends not just on specific harmful or beneficial activities, but also on how users transition between activities?
When people learn with ChatGPT instead of following their own searches, they end up knowing less, caring less, and producing worse advice, even when the facts are the same.

a while back i threatened to share this. finally online
for detection tasks we often systematically estimates sensitivity wrong. we need to control for unequal variance in models, but we often don't coz it needs extra data
now there's a virtually 'free' way to do it
