😍 Our latest is out now in @commspsychol.nature.com. 🤩 We show with Bayesian modelling and experimental manipulation of uncertainty that developmental differences in social influence depend on differences in the internal uncertainty people have about their choice
doi.org/10.1038/s442...

Internal uncertainty impacts social information use in risky choice across adolescence - Communications Psychology

Adolescents’ choices are influenced by others. A social risky choice experiment and Bayesian modelling reveal that age differences in internal uncertainty, being unsure how to choose, relate to differences in susceptibility to social influence.

Check out this new preprint on factorized representations and generalization, led by the fabulous Sam Hall-McMaster (and selectively generalized bonus reading recommendations by @nicoschuck.bsky.social) ✨

Nico Schuck @nicoschuck.bsky.social · Aug 2

Some similarities matter, others don’t—a great Labatut book with a yellow cover means books by Labatut are good, not yellow books are good. Factorized representations support such selective generalization. Check out our study on select. gen. by Sam HallMcMaster in collab with @gershbrain.bsky.social

Excited to share our latest work spearheaded by @anikaloewe.bsky.social & @maritpetzka.bsky.social. 20 min naps increased the chance to solve an insight task if sleep reached N2 stage; but the EEG spectral slope was the best predictor of insight dx.plos.org/10.1371/jour...

N2 sleep promotes the occurrence of ‘aha’ moments in a perceptual insight task

Sleep supports memory consolidation, but can it also facilitate memory reorganization? This study reveals that N2 sleep, but not N1 sleep during a nap, increases the likelihood of having an 'aha' mome...

preprint alert 🚨
1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇

🚨 Finally out! My new @annualreviews.bsky.social in Psychology paper:
www.annualreviews.org/content/jour...
We unpack why psych theories of generalization keep cycling from rigid rule-based models to flexible similarity-based ones, then culminating in Bayesian hybrids. Let's break it down 👉 🧵

Is "Git-anuary" a thing? 🤔 Committing to finally learn Git (did you git the pun)? 💫

Anyway, last month we wrapped up two great courses: Full-semester course @uni-hamburg.de & 3-day course at ZI Mannheim! lennartwittkuhn.com/news/

As always, the Git journey continues in our Version Control Book 🚀

It’s a Preprint! 👋

We show how we can dissociate perceptual from value-based mechanisms of generalisation + that stronger gen. in anxiety is associated with value rather than perception.

We could basically get reproducibility checks for free, if papers were computational notebooks (Jupyter, Quarto, RMarkdown, etc.), only successfully rendered versions accepted for publication and everything automated via pull request triggered CI/CD pipelines.

Lennart Wittkuhn @lnnrtwttkhn.bsky.social · Dec 8

„Maybe reproducibility should have a practical expiration date anyway, since it’s mostly useful around the time of publication.“

I agree. Maintaining reproducibility for decades is great but hard. It should be verified at the time of publication. But who does it? Journals? Reviewers?

I want to start doing these little #reproducibility side quests with other people's work. Anyone have any suggestions?
