How do we equip #AI with the social intelligence it needs to be a good teammate, collaborator, or driver?
Embedding real-time cognitive models in DNNs allows them to pick up on humans' latent goals and motives, providing a big step toward effective AI theory of mind:

I’m a social psychologist building computational models to study social cognition, attitudes, polarization, and how people update beliefs.
Evidence accumulation models, Hierarchical Bayes, Agent-based models, NLP, etc.
Interested in formal theorizing!
Abstract submission are open for the MathPsych/ICCM 2026 conference in Montreal July 17 to 21, 2026 mathpsych.org/conference/23/ The submission deadline is February 28!

It posits a specific mechanism behind behavior on implicit cognition tasks (IAT here; working to implement it to other tasks). We believe it enhances theory and psychometrics🙌

Machine learning / AI approaches can work well for model comparison and fitting, but how do they stack up against likelihood-based methods like hierarchical Bayes / MCMC?

(Generally the same for fitting, but neural networks were better for model comparison!)
The 2025 MathPsych/ICCM meeting starts tomorrow with a day of workshops and symposia!

Spoiler: the answer is that they are both special cases of a more general representation of evidence accumulation, and yes you can tell the differences using at least four methods!
As a bonus, we provide machine learning methods for fitting and comparing a variety of evidence accumulation models.
What are the differences between diffusion and accumulator models, and can you even tell them apart?

How do people make good decisions when their options change over time, such as dynamic housing markets?
New paper at Psych Review suggests evidence is accumulated for unavailable options -- a serious challenge to "option-specific" diffusion / accumulator models:

We (@colinsmithpsych.bsky.social and @peterkvam.bsky.social ) give a tutorial on a mathematical model of attitudes associations, the Tug-of-war model (TOW), as applied to IAT data (N > 10,000). TOW quantifies associations as (1/13)

How do we make choices when our options change over time? In a new paper with @lazyneuron.bsky.social
& Andy Fitch, just accepted at Psych Review, we explore "alternative-general" representations of evidence that allow us to make good decisions even when our options shift.
