New paper out! Here we show that attentional biases induced by reward history depend on awareness of such reward history (w/ @jlupiane.bsky.social and @mavadillo.bsky.social).

Great paper giving a rational explanation for the gambler's "fallacy".
Bayesians Commit the Gambler's Fallacy
The gambler's fallacy is the tendency to expect random processes to switch more often than they actually do—for example, to assign a higher probability to heads after a streak of tails. It's often ta...

What is the brain for? Active inference is widely discussed as a unifying framework for understanding brain function, yet its empirical status remains debated. Our review identifies core predictions across the action-perception cycle and evaluates their empirical support: osf.io/preprints/ps...

Do goal-directed actions minimize prediction error? Together with @haslagter.bsky.social and @fahrenfort.bsky.social I identified falsifiable predictions of active inference and reviewed the extent to which they are supported by empirical results. Read the preprint here: tinyurl.com/2by8k3h6

Our experiences have countless details, and it can be hard to know which matter.

How can we behave effectively in the future when, right now, we don't know what we'll need?

Out today in @nathumbehav.nature.com , @marcelomattar.bsky.social and I find that people solve this by using episodic memory.

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.
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. 🧵

Comparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding.

RegCheck was built to help make this process easier.

Today, we launch RegCheck V2.

People violate Occam's razor when selecting between predictive models. This is surprising given past research (including my own) showing a preference for simplicity.

Thoughts: You shouldn't use the ES, but you can use the SD (see also #192) for planning.

🚨 New preprint 🚨

Multisensory integration is often described as basic, robust, even ✨“cognitively impenetrable” ✨

But does the brain still bind the senses when alertness drops? 😴🧠

🔗 We tested this during natural sleep onset:

Drowsiness alters the neural dynamics but not the core computations of multisensory integration
Fluctuations in alertness shape perception and behaviour, yet how they affect the brain’s ability to integrate information across senses remains poorly understood. Here we investigated whether multise...
