New Cogsci preprint, "Introducing the Extinction Gambling Task," with Adam Harris, David Kellen, and
@HenrikSingmann. We introduce a risky choice task in which participants can lose their (entire) bonus pay when choosing the risky option and drawing the extinction event.

In this article, Maier et al. show that metacognitive learning from consequences can shape moral decision-making. @MaxMa1er @vanessachg_ @FalkLieder @RtnlAltruismLab

Excited to share that our paper is now published in PNAS! pnas.org/doi/10.1073/pnas.24…
We updated this preprint (osf.io/preprints/psyarxiv/aj…) with a new study investigating sources of this yes-no framing bias and amplified omission bias in LLM moral decision-making. Results suggest that they likely arise from fine-tuning for chatbot applications. @MaxMa1er @FalkLieder

There is a major improvement to the RoBMA package. Model structure and parameters can be estimated within a single MCMC yielding a tremendous speedup!
A Bayesian publication bias model-averaged meta-regression can be estimated in less than a minute now!

New preprint with @MaxMa1er and @FalkLieder, titled "Large Language Models Amplify Human Biases in Moral Decision-Making." In this paper, LLMs and participants make decisions in realistic moral dilemmas. We found that LLMs exhibited stronger omission bias than participants.
Our paper on "Model-Averaged Bayesian t tests" is now published in Psychonomic Bulletin and Review

🚨 Job alert 🚨
One more week to apply for two positions (PhD and Postdoc) at @arc_mpib and @mpib_berlin on using LLMs to improve generalizability in the behavioral and social sciences LLMs.
The positions are fully funded for three years. Apply by October 13! Thank you for sharing!

🚨New preprint!🚨Excited to share my 1st PhD project with @BonanZhao @cocosci_lab @natvelali
Teaching is a powerful way to pass on "tools for thought" to solve new problems. How well do existing teaching models of teaching capture this process?
Link: osf.io/preprints/psyarxiv/zx…
We updated our preprint on moral learning, now titled "Metacognitive Learning from Consequences of Past Choices Shapes Moral Decision-Making," with three new experiments and computational modeling to capture differences in individual learning styles.
@vanessachg_ @FalkLieder
Lastly, to address potential demand characteristics, we recruited participants for a study with the learning task and then recruited the same participants for a second study with the transfer measures. Ps did not know that the two studies were related (more details in Methods).
Using this design, we again replicated the transfer effects on moral convictions and donation decisions between the two independent studies. For more details see our preprint: osf.io/preprints/psyarxiv/gj…
