Habit research has accumulated many tasks that supposedly tap into the same construct, yet their psychometric properties are rarely examined. Here, we assess their construct validity evidence and analyze their reliability to facilitate interpretation of previous studies and guide novel research ⬇️📝

A CIMCYC study reveals how the brain organizes information to adapt to new situations
Every day, we face new situations with surprising ease: from understanding a rule that has just been explained to reacting appropriately to an unfamiliar sign. But how does the brain manage to turn a ...

Happy to share our article now published in #psynomBRM w/@antovami.bsky.social, @frangfr.bsky.social & @davluque.bsky.social. We tested the replicability, reliability, and convergent validity of two promising paradigms for measuring habitual control. 📄 doi.org/10.3758/s134... short 🧵 below

Animal research has shown that repeatedly performing a rewarded action leads to its transition into a habit—an inflexible response controlled by stimulus–response associations. Efforts to reproduce th...

Yesterday at #ICON2025 I got to present our poster with #EttoreAmbrosini, @palencianoap.bsky.social, and @mruz.bsky.social on flexible task representations. I loved the chance to share our preliminary results and hear such thoughtful feedback!

🧠💻 We (a bunch of colleagues at @cimcyc.bsky.social) just released a programming guide for psych & cog neuro students. Instead of a tutorial, this is a starting point: a collection of reflections, examples, and recommendations. 👉 Still growing, but ready to explore: wobc.github.io/programming_book/

The what and when of visual surprise: EEG shows that high-level visual surprise emerges rapidly and modulates neural responses ~200ms after stimulus onset. New preprint with @paulapena.bsky.social and @mruz.bsky.social available here: doi.org/10.1101/2025... Summary 🧵 below

We are pleased to announce our next Time-resolved Neuroimaging (EEG+) #CIMCYCsession which will be held by Paula Pena. She will present the results of her work www.jneurosci.org/content/earl... No prior experience in EEG is needed, just curiosity and a willingness to discuss ideas. Save the date!

New preprint! In this study, we assessed the reliability and validity of the measures intended to capture the "habit construct" in the forced-response task and the aliens outcome-devaluation task. w/ Antonio Vázquez-Millán, @frangfr.bsky.social and @davluque.bsky.social
