 ### Decision-making: data analysis
 _See [here](https://anne-urai.github.io/lab_wiki/IBLdata.html) for some examples on getting started with existing IBL data_.
 - Does choice history bias correlate with psychopathology, e.g. impulsivity? Reanalyse data from [Rouault et al. 2019](https://doi.org/10.1016/j.biopsych.2017.12.017) by fitting models of choice history bias (e.g. [logistic models](https://www.nature.com/articles/ncomms14637) or [drift diffusion models](http://dx.doi.org/10.7554/eLife.46331)). Can also collaborate with Tobias Donner to analyze personality questionnaires from [these data](https://www.nature.com/articles/s41467-022-33237-5) (see also [my PhD thesis](https://anneurai.files.wordpress.com/2020/12/urai.pdf), p.99).
+- Do choice history biases transfer across tasks (i.e. do observers have an meta-prior estimate of the environment's stability, and apply it in different modalities/contexts)? Find dataset with large number of subjects who did multiple tasks, and correlate estimates of repetition/alternation behavior.
 - How do decision-making strategies (such as perseverance) change with ageing? Fit behavioral models (e.g. [Ashwood et al. 2022](https://www.nature.com/articles/s41593-021-01007-z), [Findling et al. 2019](https://doi.org/10.1038/s41593-019-0518-9)) to decision-making data across the lifespan (both mice and humans). Potential collaboration with Peter Murphy, Dublin.
 - Do learning and decision-making vary with the biological clock, and is it easier to learn when consistently practicing at the same time of day? Potential collaboration with [Christian Tudorache](https://www.universiteitleiden.nl/en/staffmembers/christian-tudorache#tab-1).
 - How can we disentangle choice updating from slow drifts in decision criterion? Apply method proposed by [Gupta and Brody](https://www.biorxiv.org/content/10.1101/2021.09.17.460767v1), with Robin Vloeberghs.
