**10 years of mixed models: It's (well past) time to set your contrasts.** *Laurel Brehm & Philip M. Alday* This is documentation and data from a project looking at how psycholinguists (fail to) appropriately describe contrast coding in their papers. The subfolders are the two main efforts to present the results to a hopefully broad audience 1. **AMLaP 2020**: Slides from a talk on this given at AMLaP 2020. The Rmd file is what was used to generate them; the HTML and PDF files are the rendered slides. Supporting graphics are in img.zip. [Recording of talk](https://mediaup.uni-potsdam.de/Play/Chapter/223). 2. **Current Analysis and Preprint**: Snapshot of current version of manuscript (see files history for prior versions). This reflects the latest submission to a journal, currently the Journal of Memory and Language. The Rmd file is both the analysis code and the manuscript. The PDF is the rendered output. Contrasts_Papers_Deidentified.tab is a tab-separated file containing the de-identified annotations for all papers that were used in the analysis, i.e. the data. The id field in this file was generated by using the script deidentify.R. Using hashes to de-identify papers makes it easy for an individual to check the annotation of a single paper, but makes it more difficult for a casual inspection of the annotations to be used to shame or otherwise "call out" an individual author or manuscript. Finally, renv.lock is for tracking the version of R and associated packages used in generating the PDF from the Rmd file and thus aid in reproducibility.
