Evolving choice hysteresis in reinforcement learning: Comparing the adaptive value of positivity bias and gradual perseveration | PNAS
The tendency to repeat past choices more often than expected from the history of outcomes
has been repeatedly empirically observed in reinforcement...

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/...

🚨 New preprint 🚨
Analyzing the academic trajectories of 78,216 psychology researchers, we demonstrate a persistent gender attrition gap, with women psychologists dropping out of academia at consistently higher rates than men psychologists.

Slowing change may be our last line of defense

Linux OS always, but we really need to make LibreOffice better. So far it sadly really cannot compete with Office 360.
For the EU, this should be a very urgent matter of national security. All EU member states should build on Denmark's wise strategy to phase out Microsoft products

Interested in finding out what causes you to disengage from a task? Catch my talk about the dynamics of arousal and engagement at #CCN2025 @cogcompneuro.bsky.social today at 11! You'll find me in room C1.04, and Friday afternoon at poster C168.

Very excited for @cogcompneuro.bsky.social, where I will present two nice ongoing projects!
On Tuesday, meet me at poster A105 to learn about a huge value-learning dataset we are putting together (so far 3800 human subjects). Turns out, range adaptation is all the rage!

This is the type of important research that will hopefully guide policy-makers to go beyond the "we just need role models"-excuse

Rage coding this morning using #TidyTuesday NSF grant terminations data.
Research in STEM Education and Social, Behavioral, & Economic Science is clearly being targeted by the current administration.

Women leave academia at higher rates than men at every career stage, and attrition is especially high among three groups: tenured faculty, women in non-STEM fields, and women employed at less prestigious institutions, a #ScienceAdvances analysis finds.
Gender and retention patterns among U.S. faculty
Women faculty are more likely to leave their jobs than men, most often due to workplace climate, rather than work-life balance.
