This is our first (scientific) collaboration with @cmziemba.bsky.social (a plan hatched during our long COVID lockdown in Bogota) and it's been very fun! Big thanks to @zoebsinger.bsky.social & big shoutout to our exceptional postbac Corey Plate for finishing this right before leaving to his MD/PhD!

The paper also includes the release of a toolbox for implementing a Bayesian hierarchical version of CASANDRE (in Stan) that is applicable to both value-based choice data and perceptual choice data: github.com/CDN-Lab/CASt...

We find that metacognitive ability is highly conserved for distinct preference-based decisions and we find some evidence for conservation across objective and subjective decisions.
Figure 4a from manuscript. It depicts a scatterplot relating the metacognitive ability parameter meta-uncertainty from the CASANDRE model from a delay discounting task and a risk and ambiguity task across participants.

This is difficult to do because these types of decisions do not have an objectively correct answer. However, by combining utility modeling and the CASANDRE model of confidence we can characterize metacognitive ability for these types of decisions in the same way we probe it for perceptual choices.
Figure 1d from manuscript, a cartoon description of the process model of confidence, CASANDRE, that can describe both objective and subjective decisions.

I’m beyond excited to share that I’ll be starting my PhD in Cognitive Psychology at Yale this fall with support from the NSF GRFP! I feel deeply grateful to be joining this community and to work with @robbrutledge.bsky.social and the Rutledge lab!

Hooray Clara! I am so proud of you! It’s been truly awesome to work with you these past 2 years. I can’t wait to see all the beautiful work you will do next.

I'm pleased to report that the board has now heard from NIH that the appointments of these three investigators and similarly situated folks are being extended. Thank you NIH! Delighted that the stellar work there will be continuing!

Compelling pushback from @jmgrohneuro.bsky.social and the Board of Scientific Counselors at the National Institute on Mental Health (NIMH) regarding termination of tenure-track investigators driven by DOGE.
