    Now published in PNAS: "Uncertainty in learning, choice, and visual fixation". For a summary, see the thread by

    And it is finally out :) You can read the final version online in PNAS: Thanks again to everyone who helped making it happen!

    We're looking to hire a Lecturer in Quantitative Psychology (equiv to assistant professor). Please forward to all good candidates and/or apply yourself! From personal experience, UCL Division of Psychology and Language Sciences is a great place to work :-)

    It's been a long process, but we have just submitted a revision, new upgraded version is up on : , with new experiments and hopefully much clearer manuscript!

    Our new work context learning and decision making is now submitted: "It’s new, but is it good? How generalization and uncertainty guide the exploration of novel options", preprint can be found at via

    Finally, the second post in series on fitting RL models with R. This one covers numerical maximum likelihood estimation, starting values, and parameter identifiability:

    First blog post in series on fitting RL models to human behaviour with R. This one covers defining and simulating three Bayesian RL models for a (restless) bandit task, combining a Kalman filter with softmax, UCB, and Thompson sampling for choice:

    Want to find out what hides in UCL bins? 🧐 Well, we've now got a pretty good idea. 🤓 🙈 Plus some tips on what can and what can't be recycled at ♻️ Big thanks to & @GreenUCL for making this study possible!

    For several weeks PhD Student Sabine Topf and colleagues studied the contents of mixed-recycling and non-recyclable bins in 6 UCL locations. Read more about this amazing project here: @GreenUCL

    How do people explore the vast decision spaces that define our lives? New paper in by , Eric Schulz, et al. shows that people generalize from limited experiences to a large set of unobserved options.

    We are often presented with too many choices when searching to explore them all. Wu et al. show how a combination of generalization and optimistic sampling guides efficient human exploration in complex environments

    We are really proud to say that our paper is out today! 2.5 years and thousands of hours of computation have been poured into studying one of the key components of human intelligence. (Summary follows below)
