🚨 New Preprint 🚨 Prolonged Isolation is associated with an increased behavioural sensitivity to ‘Likes’ on social media. 🧵 Social media rewards are inherently social—but does posting change during social isolation, when in-person social rewards are limited? It turns out, yes!

This is an exquisite demonstration of using intracranial recordings in humans to validate our findings that amygdala neurons encode the value of exploring in NHPs. www.nature.com/articles/s41...

🚨 New paper alert! Do time constraints reveal habitual behaviour? 🤔 We directly compared two major paradigms in the habit research field (Outcome Devaluation vs Response Remapping) under identical training and forced-response conditions 🧠 ⏲️ ⌨️ preprint: osf.io/preprints/ps...

In our preprint "Limited evidence for reduced learning rate adaptation in anxious-depression, before or after treatment", led by @stephsuddell.bsky.social and Lili Zhang, we fail to find a robust association between anxious-depression and learning rate adaptation osf.io/preprints/ps...

🔷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...

Dan @danmirea.bsky.social will share his science communication and public engagement expertise as an educational content creator (@danniesbrain on TikTok and Instagram) and program coordinator of @mental_health_for_romania

Sign up for our *free* online Science Communication Workshop on May 5&7! Tinyurl.com/scicomins Featuring our incredible workshop instructor @choano.bsky.social and our amazing social media science communication panel: @sciencewhizliz.bsky.social, @danmirea.bsky.social, and @moadlc.bsky.social.

Huge congratulations to Chantal @talvaldivia.bsky.social for receiving an NSF Honorable Mention and to Dan @danmirea.bsky.social for being awarded a Procter Fellowship from the Graduate School earlier this month! We’re so proud of their achievements!

Kristina Olson and I have a truly incredible advisee who won an NSF but had no luck on clinical psych PhD applications this round. Anyone able to consider another candidate this late in the process? Trust me, you won't regret it!

I don’t dare to tell you how many years this took, but the project that I started as a MSc intern and kept working on throughout my PhD is now finally published: www.nature.com/articles/s44... [1/9]

We’re thrilled to celebrate Erik for co-authoring the Best Paper at SAS (Nencheva et al., 2024) and Dan for winning the Diversity Award! Beyond these achievements, our lab members gave fantastic talks: @eriknook.bsky.social @raziasahi.bsky.social @danmirea.bsky.social @claire-whiting.bsky.social

New comment by @faridanvari.bsky.social and friends arguing that psychology is fragmented into the study of too many constructs and measures with too few links. www.nature.com/articles/s41...

How can we reduce conceptual clutter in the psychological sciences? @ruimata.bsky.social and I propose a solution based on a fine-tuned 🤖 LLM (bit.ly/mpnet-pers) and test it for 🎭 personality psychology. The paper is finally out in @natrevpsych.bsky.social: go.nature.com/4bEaaja

🚨New Preprint Alert!🚨 To what extent can we use language to measure psychological and subjective well-being? 🤔 We tested how well language-based models (i.e., bert-based embeddings) predict subjective & psychological well-being across three studies. Here’s what we found! 🧵👇

What is driving social foraging dynamics in the wild? In a new pre-print, we investigate decision-making mechanisms in large groups of Finnish ice-fishers competing for resources: osf.io/preprints/ps... Big thanks to drone pilot Félicie Dhellemmes. 1/n youtu.be/I_RH2diXcAk

New preprint out with @summerfieldlab.bsky.social! When does new learning interfere with existing knowledge? We compare continual learning in humans and artificial neural networks, revealing similar patterns of transfer & catastrophic interference (1/8) osf.io/preprints/ps...
