#OCD is a understudied disorder, meaning that we know way too little about the underlying (brain) processes. We have thus built the Brain Explorer app www.brainexplorer.net where everyone can easily contribute to understanding OCD. #MentalHealthAwareness @tueneurocampus.bsky.social @ucl.ac.uk

Brain Explorer - Test your brain power

The brain explorer app for Apple and Android tests your brain functions and helps researchers to understand the brain. Explore your brain power and how brain functions are important for mental health.

When I began my PhD, there was a major disconnect between my own lived experience and the way researchers probed mental health-behaviour links. I hope this work inspires others to use new designs to appreciate the complexity of human beings and their experiences. link.growkudos.com/1f5ss3bn1ts

This is a great study, if I may say. We have had a lot of data showing correlations between subjective assessments and behaviour between individuals. With this study, we are starting to see how they interact over days within individuals. Congratulations @samuelhewitt.bsky.social!

A little bby from my PhD is published! we did a complex study to answer a simple Q: do day-to-day feelings impact choices? A: Yes. When feeling motivated (independent of other stable or unstable feelings) choices changed because rewards seemed greater. open access link: doi.org/10.1073/pnas...

People making demands of BlueSky tech team, mods etc because it’s getting busy: BlueSky has a staff of 20. None of us are paying a penny to use it, and it has, at the moment, no way to monetise itself, as far as I can see, because it’s trying to resist any pivot to algorithmic ads or selling data.
