However, he was -- and let's be slightly glib here -- some guy from The Netherlands who wrote social psychology papers.

- 1/4 I’m super excited to share our latest PNAS paper: a 7T-fMRI study shows that functional connectivity between habenula and VTA in humans is associated with individual differences in negative learning bias, which further associates with higher anxiety and depression scores. doi.org/10.1073/pnas...
- 2/4 We showed that negative learning bias derived by a 2 learning-rate Rescorla-Wagner model captured pro-variance bias (PVB, a manifest of risk-seeking behaviour qualified using our novel reinforcement learning task). Negative learning bias & PVB are associated with anxiety and depression scores.
- Reposted by wanjunlin(1/3) Focused ultrasound stimulation is a versatile neuroscience tool. Depending on parameter settings it can safely and reversibly alter brain function, or it can lead to lasting tissue damage. That’s why we have safety guidelines (see ITRUSST: www.sciencedirect.com/science/arti... ).

- Reposted by wanjunlinNew paper our in @pnas.org, lead by @isabellehoxha.bsky.social with Léo Sperber. We use evolutionary simulation to assess and compare the adaptive value of positivity bias and gradual perseveration in reinforcement learning. Follow the thread below (and Isabelle!) for more details!
- Ever wondered why you keep going to that restaurant with stale fries? Is it because you went often in the past (perseveration) or because you remember past good experiences better (positivity bias)? Our study out in PNAS investigates the normative basis for these biases www.pnas.org/doi/10.1073/...
