This project contains materials to accompany the paper, entitled "Parallel developmental changes in children’s production and recognition of line drawings of visual concepts", in press at *Nature Communications* (10.1038/s41467-023-44529-9). **OSF Repository Overview** **Codebase**: The main experimental and analytical code is contained in the Github repository linked below and [here][2]); a README in the repository gives a brief overview of the repository structure as well links to other repositories containing code used in the paper for tracing evaluation and semantic part annotations. Preprocessed data structures are hosted within the GitHub repostiory. Rendered html pages show the code necessary to generate the main figures and results in the paper. **Drawing database:** The drawing database itself is *not* contained the GitHub repository as there are too many files. Instead, pngs and metadata are hosted in the "Drawing data" section of this OSF repository. There are two main data types that are linked here: (1) rendered pngs for all of the drawings in the filtered database (will be contained in "stringent_filtered_database.zip") metadata for these pngs are in the "drawing metadata" folder (2) csvs for each category which have metadata as well as individual svgs for each stroke in each drawing. While the analysis pipelines originally pull directly from a mongodb database on a private server, these CSVs will be provided so that others can re-use these data. **Pre-registrations:** Versions of the scripts for analyzing the visual recognition data are also contained in a separate folder (recoggamees_prereg_scripts) for archival purposes.
