This weekend, I'm going on a sponsored walk to help raise money for my friend's younger brother's cancer treatment. If able, I'd really appreciate if you could share or sponsor me here: sites.google.com/view/alex-wa...

💡Does anyone have any good go-to introductory readings / materials for network analysis? e.g. introducing definitions of nodes / edges / global and local graph properties, etc? 💭

In the 2020 Election Project, Meta collaborated w/ academics to study how FB impacts elections. ⬇️ @aanixel.bsky.social, @fassiluisa.bsky.social & I argue that such research collaborations, w/ clear conflicts of interest, should be regulated. Would love to hear thoughts!💬 www.pnas.org/doi/10.1073/...

Important work on perceived social media addiction 👇

🚨Friends, we’re happy to share that our book is available for pre-order! 🎉 We aimed to cover all the foundations of the topic in an accessible manner for a large audience. It could help set up a bachelor-level curriculum on the topic. Pre-orders are very key for the fate of books: shorturl.at/Dxbif

Looking forward to speaking tomorrow at the Cambridge University Behavioural Insights Student Society about the psychology of social media - come along if you're in Cambridge! cubiss.wixsite.com/cubiss/event...

This is one of the rare papers that completely changed my thinking about the field I work in. Have a read!

I spoke to The Economist @economist.com about dopamine detoxes - thank you @ainsliejstone.bsky.social for the write-up! www.economist.com/science-and-...

as a condition of funding, we were asked to affirm that we wouldn’t undertake any diversity, equity, and inclusion work, whether or not we used the government funds to do so. The PSF simply couldn’t agree to that statement,

🚨 New Preprint 🚨 Some people are at greater risk of experiencing negative mental health outcomes of social media use than others, but why? 🧵 We examined whether individual differences in cognitive processes shape risk and resilience to mental health effects on social media: osf.io/preprints/ps...

🚨Out now in @cp-trendscognsci.bsky.social 🚨 We explore the use of cognitive theories/models with real-world data for understanding mental health. We review emerging studies and discuss challenges and opportunities of this approach. With @yaelniv.bsky.social and @eriknook.bsky.social Thread ⬇️

Really excited to see this out, led by the brilliant @bcdavidson.bsky.social

@anne-urai.bsky.social , @weijima.bsky.social , Ili Ma and @tsonj.bsky.social organised an amazing workshop on 'Science for Social Good' at #CCN2025 @cogcompneuro.bsky.social We wrote a blog reflecting on it: anneurai.net/2025/08/14/r...

Looking forward to giving a Contributed Talk at #CCN2025 @cogcompneuro.bsky.social tomorrow on this study! Come and say hi if you're at the conference, or watch the livestream here (10am BST / 11am CET) 👉 hva-uva.cloud.panopto.eu/Panopto/Page...

Very cool work linking reward learning and social learning 👇

So well deserved 🎉

Excited to co-host a workshop at @rldmdublin2025.bsky.social with @danmirea.bsky.social & @anadasilvapinho.bsky.social next week! We will be exploring applications of reinforcement learning to real-world data 🌳 Sign up to our mailing list to receive updates: sites.google.com/view/rlinthe...

🔷New in Biological Psychiatry🔷 **Old Strategies, New Environments: Reinforcement Learning on Social Media** In this Review, we argue that the computational framework of Reinforcement Learning can help us understand social media behaviour: www.sciencedirect.com/science/arti...

Nuanced, theoretically-grounded framework for designing social media interventions 👀

Important new study about social media use in vulnerable young people:

@lukasgunschera.bsky.social and I spoke to @adigitaltanay.bsky.social about our work on social media and cognition - have a listen to hear how we ended up here, what we have enjoyed reading & more 📕🎙️

Learning so much at the Amsterdam Complexity School for Climate Change, beyond grateful for the opportunity to hear from such incredible speakers and meet so many kind & motivated people 🤝

Important, timely and innovative thinking on the science-policy interface for tech research 👇

Does anyone know of an available dataset including (1) passively collected data on what Apps are being used in the foreground of one's phone and when, & (2) mental health questionnaire measures (from 1 or many time points)? Thank you 🙏

Beautiful science metaphor written by Monica Emili Garcia-Segura for @nos-cambridge.bsky.social

Looking forward to speaking at the @mrccbu.bsky.social science night 🔭

One more day to submit an abstract for a flash talk at our RLDM workshop 😎 please share with anyone who would be interested!

🔔Call for abstracts! 🔔 We're inviting applications for flash talks at our workshop on Reinforcement Learning with real-world data at @rldmdublin2025.bsky.social, details below ⚡⚡⚡

💥Postdoc Opening! 💥We (@lucasmolleman.bsky.social & Piet van den Berg) seek a postdoc to study social learning and cultural evolution. We are looking for someone with math/computational modeling skills & interest in human behavior. Get in touch if you have any questions! shorturl.at/W6Qsb

Everyone needs to know that these fires were made possible by global heating, which is caused by the fossil fuel industry, which has lied and blocked action for half a century. And that this will all get much, much, much worse until we end the fossil fuel industry
