Do you have some cool summer findings on decision-making? Tell everyone about it! The late-breaking abstract deadline for October's Society for Neuroeconomics conference is August 4th: neuroeconomics.org/abstract/

New paper in iScience on the neural dynamics of decision-making during learning. We analyzed behavioral and EEG data from 510 participants on the RLWM task (developed by @annecollins.bsky.social & Michael J. Frank). doi.org/10.1016/j.is...

A few days at the @jspsych.org Summer Hackathon 2026 turned into jspsych-ado: adaptive Bayesian experimental design that runs in the browser along with any jspsych experiment. It adapts each what it presents on each trial to what it has learned from a participant's earlier responses:

Move over, GLM-HMM—there’s a new hidden Markov model in town. In our new preprint, we introduce the DDM-HMM: a model that jointly infers latent decision states from reaction times and choices. Using 24-hour behavioral data from rats, we found that evidence accumulation changes with time of day!

Diurnal rhythms of choice: a novel state-dependent drift diffusion model uncovers time-dependent changes in rat decision making https://www.biorxiv.org/content/10.64898/2026.05.25.727672v1

Time's running out to sign up for the Economic Science Association world meeting July 15-17 in beautiful Marina Del Rey (Los Angeles). The day before (July 14), we're hosting a "choice process" symposium with many amazing speakers. Best part - it's free with ESA registration.

Autonomous AI agents are now built into many browsers. A naive user can take an online survey with as little as the click of a button. For behavioral research, which depends heavily on online samples, this is a real problem. (1/7)

🚨New preprint and our results are rather concerning.. We find the "boiling frog" equivalent of AI use. Using large-scale RCTs, we provide *casual* evidence that AI assistance reduces persistence and hurts independent performance. And these effects emerge after just 10–15 minutes of AI use! 1/

🚨NEW PREPRINT (w/ Fleming Peck & Hongjing Lu) "Spontaneous emergence of context-dependent statistical learning in humans and neural networks" We are constantly predicting what will happen next. Yet the same cue can lead to different predictions depending on context. How might this work...? 🧵1/8

How do people search for information to make efficient decisions? Our new theory, now out in Psychological Review, suggests that an efficient search rule is (at the core of) the answer. And eye-tracking data support our theory. Check out here (it's open access): psycnet.apa.org/fulltext/202...

Decomposing Economic Choices with Drift-Diffusion Models

Many decisions arise from a dynamic process of information accumulation and comparison. Thus, to fully understand decision-making, we must decompose the choice process into its parts. Here, we review ...

One initial line of defense could be to require transparency statements regarding how instruments have been vetted to combat malicious users, based on best practices (like a STAR editor check). In a recent workshop, we aimed to create such a compendium (see @andreaaaaa.bsky.social for access)!

New paper in @cognitionjournal.bsky.social, where we show how attention impacts political choices. With an eye-tracking study, we find that people's votes aren't set in stone - they take longer to vote on divisive issues and can be swayed by gaze manipulations. authors.elsevier.com/sd/article/S...
