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? link.springer.com/article/10.3... (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! #iccmpsyched but can't make it this year? Get your fomo here:

What are the differences between diffusion and accumulator models, and can you even tell them apart? "The Tweedledum and Tweedledee of dynamic decisions: Discriminating between diffusion decision and accumulator models" open access link: link.springer.com/article/10.3...

I am currently co-organizing a preconference for Psychonomics with the topic "Memory in the Wild". Registration will close soon! Check it out: mathpsych.org/conference/17/

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: psycnet.apa.org/fulltext/202...

First first-author paper submitted; preprint: osf.io/preprints/ps... 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)

The 2nd talk in Measurement & Reasoning is “Revisiting the role operational definitions in psychological science” by Peter Kvam @peterkvam.bsky.social mathpsych.org/presentation... #iccmpsyched

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. osf.io/preprints/ps...

Just got this in an email from UF admin. They like to do this on Friday afternoons so that we can enjoy our weekends.

A short piece on what we do -- and more importantly, don't -- know about the relationship between human behavior and evolution. Plus, what approaches like computational evolution can tell us: www.psychologytoday.com/us/blog/defi...

What is a scientific model? www.psychologytoday.com/us/blog/defi... Models bridge the gap between what we can understand and what we want to understand -- and extend that bridge in both directions. Now on the front page of Psychology Today! psychologytoday.com/us #PsychSciSky #scicomm #science

We often take them for granted, but operational definitions are a weird vestige of early 20th century science. It's time for psychology to leave them behind in favor of better measurement models: Re-assessing the role of operational definitions in psychology osf.io/preprints/ps... (Reposted 🐦🦣🧵)

Have you heard these claims? "AGI (short for “artificial general intelligence”) is imminent!" or "At current rate of progress, AGI is inevitable!" We explain why, and present a formal proof that, such claims are false and misleading. irisvanrooijcogsci.com/2023/09/17/d...
