Online surveys have been a boon for science, but in the AI era, not all respondents may be human. A study validates AI detection tests that effectively separate verified-human participants from AI agents and finds 6–41% of respondents are likely bots. In PNAS: https://ow.ly/8ILa5100m4F

Update! 220 miles. 82 hours, 52 mins! Top 50 males. So happy with this one. Feeling recovered, now back to work!

Not work related. Sorry if I am slow to respond in the next few days. Today I start my journey toward completing the mammoth 218 miler. Follow along on the live stream! Bib number 273! mountainoutpost.com/events/the-m...

Women with bulimia nervosa typically avoid high-fat foods, yet binge on them during periods of negative mood. Why? In our new paper in @elife.bsky.social, we used computational modeling to find out 🧵 elifesciences.org/articles/105...

📣 NEW PREPRINT ALERT! 📣 📝Preprint: www.biorxiv.org/content/10.6... When choosing between options with multiple attributes, what does the brain actually compare - individual attributes or integrated option values? We combined EEG + eye-tracking to find out... and found evidence for the latter 🧠

📣We are hiring!! I am accepting applications for a postgraduate research associate (PGA) position. If you are interested in pursue research experience in computational psychiatry, plz apply here - yalesurvey.ca1.qualtrics.com/jfe/form/SV_... #Computation #MentalHealth #Neuroscience #Yale #Jobs

I expect to recruit a PhD student this cycle! The Control and Decision Making Lab at WashU studies control, effort, and decision making, combining behavioral experiments with modeling and neuroimaging. If that sounds cool, check out our work: cdmlab.wustl.edu. How to apply: psych.washu.edu/apply

We are growing the team! Currently recruiting a PhD student (Fall 2027 start, portal opens mid-Sep) and hiring a lab manager. Inquiries from postdocs, prospective PhD students, and research assistants are all welcome. Apply now! www.heffner-lab.com/join

A few years ago at MathPsych @singmann.bsky.social and I spoke about making an update. Well here it is new rtdists live on CRAN!

We broke Weber's law. By manipulating the prior (ie the frequencies of small and large magnitudes), we changed how people's accuracy depended on magnitude. When large magnitudes were more frequent, subjects became more precise about them. This points to efficient coding, dynamically implemented.

Now published in eLife: elifesciences.org/articles/103... We find strong evidence that activity in Pre-SMA and vmPFC scales with gaze-weighted accumulated evidence, suggesting attention directly modulates value signals in canonical decision-making circuits! 🧵 on the methods + findings:

📢New paper out today in @cognitionjournal.bsky.social led by Seoyoung Lee! Does reward spread across multiple links in memory organized in a cognitive graph? Yes! We see graded spread through a recalled (even if incorrect) learned graph. Reward preserves proximal structure to support decisions.

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...

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!

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.

🚨🚨 The Social Learning and Decisions Lab is hiring! 🚨🚨 We're looking for a postbacc project coordinator/research assistant to join our team this summer. More details about the position and how to apply here: drive.google.com/file/d/1ySeA... Please share widely and reach out with any questions!

The Behavioral Lab at the UCLA Anderson School of Management is looking to hire its next Lab Manager! Applications will be reviewed starting April 30th. jobs.ucla.edu/jobs/10354?l...

🚨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...

Worth a look if you're running online studies. Happy to be a part of this, great work led by Grace. Check out Oleg's thread; feedback welcome!

I'm excited to announce that I had my first (co-authored) book published today! "The Rational Use of Cognitive Resources" with Falk Lieder and Tom Griffiths (@cocoscilab.bsky.social ). You can read it for free! (see thread)

Chapter 📖 "Decomposing Economic Choices with Drift-Diffusion Models" with @krajbichlab.bsky.social and Xiaozhi (Taro) Yang is out in, "Neuroeconomics: Core Topics and Current Directions" edited by @dvsmith.bsky.social, @thepsychologist.bsky.social, @dfareri.bsky.social tinyurl.com/yey56tup

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)!

Why do some things stick in memory while others fade? Next Tue, Dec 9, Alan Castel (UCLA) will be presenting in @motcogmeet.bsky.social online talk series on “Memory Selectivity in Younger and Older Adults: A Value-Directed Remembering Approach.” 1/ Join us! (link below)

There's hope! This is an adversarial game, researchers will need to continuously innovate to stay ahead @kiante.bsky.social @andreaaaaa.bsky.social & @jbogard.bsky.social ran an excellent workshop at #SJDM2025 to help folks get started Materials here: kiante-fernandez.github.io/sjdm-data-va...

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...

Thanks again to the Society for Judgment and Decision Making for helping continue the discussion on creating a system for data validation in the age of accessible bots in online research. Looking forward to continuing the conversation with the community! @sjdm-tweets.bsky.social

How can we identify or block #AI #survey respondents? @andreaaaaa.bsky.social, Kianté Fernandez, @jbogard.bsky.social, and Craig Fox demoed examples, facilitated discussion, and tested our live suggestions. See their Modern Threats to Online Surveys: kiante-fernandez.github.io/sjdm-data-va...

📢 Thrilled to share our paper is out now in @natcomms.nature.com Shared computations underlie how we acquire actions that are mutually beneficial, instrumentally harmful (benefits self at the expense of others), altruistic (benefit others at the expense of self), or mutually costly 🧵 rdcu.be/eL8mZ

Excited to share our new paper out in PNAS: “Neural predictors of hidden, persistent psychological states at work.” Full paper at bit.ly/47oaGRR We brought portable fNIRS into the field to predict the subjective work-related “lenses” of business leaders. Check out the thread below for more! 1/8
