 - Can we detect cognitive strategies using constrained RNNs? Fit new models (e.g. [here](https://www.biorxiv.org/content/10.1101/2023.04.12.536629v2), [here](https://www.biorxiv.org/content/10.1101/2023.05.17.541226v1), [here](https://www.biorxiv.org/content/10.1101/2023.06.23.546250v1), [tutorial](https://github.com/kstach01/CogModelingRNNsTutorial)) to perceptual decision-making data.
 - Do mice show the same history-dependent choice history bias as humans? Implement [this work](https://2023.ccneuro.org/proceedings/0000544.pdf) in the new [HSSM package](https://github.com/lnccbrown/HSSM) and be a beta-tester. Together with Alex Fengler, Brown University.
 - How are fatigue reports related to reaction times in a task with physically effortful responses? Using data from [Mathews et al., 2023](https://www.sciencedirect.com/science/article/pii/S0010027723002378).
+- Do implicit and explicit priors differentially change biases in evidence accumulation? Fit a DDM to [these data](https://www.biorxiv.org/content/10.1101/2023.08.18.553834v1).
