If you are at @facct.bsky.social, come check out the latest work of the freshly minted Dr. @ltreiman.bsky.social! She will talk about the effects of asking for AI training consent on human decision making. The talk will be Saturday 6/27 at 10.45 in the Human-AI Interaction session (Lamartine).

Thank you @ltreiman.bsky.social for sharing your work with us on how people act differently when they know that their behavior is used to train AI. In the ultimatum game, people are more likely to reject disadvantageous offers when an AI is watching and learning. 📃 www.pnas.org/doi/10.1073/...

Honored to receive the Provost's Research Excellence Award! Thank you to my advisors, lab members, and friends at @washu.edu for your support. engineering.washu.edu/news/2025/Mc...

Thrilled that my poster on our new preprint won 2nd place at the Society for Judgment and Decision Making (@sjdm-tweets.bsky.social) conference! Read the full paper here: osf.io/preprints/ps...

So proud of my grad student @ltreiman.bsky.social on winning 2nd place in the Best Poster Award at SJDM @sjdm-tweets.bsky.social 🎉! In a preprint of this work, she demonstrates how sequential comparisons and choice-induced preferences reveal two distinct pathways to the decoy effect.

Two more posters from my group at Psychonomics and SJDM. This evening, @duyguyucel.bsky.social will present some brand new work on multidimensional reinforcement learning, and tomorrow morning @ltreiman.bsky.social will present her work on choice-induced preference in the decoy effect.

Next: Lauren Treiman developed a Frame Selection Task, where people choose how risky choices are framed. She shows that people have frame preferences and that they align with their risk preferences: risk-seeking participants prefer the loss frame more, thus facilitating their risky inclination.
