This is the part of the data and analysis code used for the following article: **Domain-specific working memory, but not dopamine-related genetic variability, shapes reward-based motor learning** Holland PJ*, Codol O*, Oxley E, Taylor M, Hamshere E, Joseph S, Huffer L, Simpson D, Galea JM (2019) - * equal contribution *Journal of Neuroscience* The article can be found online at this link: https://www.jneurosci.org/content/40/18/3604.abstract For the dataset please check that project folder: https://osf.io/rmwc2/ (I have also added the dataset to this project webpage for convenience) A pre-register is available regarding the design of our study and the analyses. The genes and alleles we studied are also specified. Feel free to have a look! Any feedback is welcome. There are two pre-registrations here, because each experiment's pre-registration was done separately. The second pre-registration is also available on its original webpage here: https://osf.io/rmwc2/ Contact e-mail: codol.olivier@gmail.com
