Cognitive affordances of South Scandinavian Mesolithic portable art as inferred from complexity and entropy measures

This is the supplementary material for the article 'Cognitive affordances of South Scandinavian Mesolithic portable art as inferred from complexity and entropy measures' by Herskind, L.L.P., Fusaroli, R., Miton, H., & Riede, F.

The supplementary material includes:

- a README, which contains instructions on how to reproduce the reported analyses
- The RStudio Project file ('Herskindetal_cog_aff_analyses.Rproj')
- SI1: Excel data sheet with the available metadata for (practically) all known portable art objects from Mesolithic South Scandinavia ('SI1_raw_data_Herskindetal2025.xlsx')
- SI2: The R Markdown file with all code used to conduct the presented analyses ('SI2_code_Herskindetal2025.Rmd')
- SI2.1: An html version of SI2, visualising the output ('SI2.1_code_Herskindetal2025.html')
- SI3: Word file with supplementary analyses ('SI3_Supplementary_Analyses_Herskindetal2025')

The image files associated with the analyses can be found at Figshare:  https://figshare.com/projects/Cognitive_affordances_of_South_Scandinavian_Mesolithic_portable_art_as_inferred_from_complexity_and_entropy_measures/255101  (USE THIS LINK TO ACCESS THE FIGSHARE FILES)
These files include:

- SI4: Folder containing the image files used for the analysis ('SI4_PC_image_files_Herskindetal2025')
- SI5: Folder containing the rescaled versions of the SI4 image files, used to test the difference in results at different levels of size and blur ('SI5_PC_image_files_rescaled_Herskindetal2025')
- SI6: Folder containing the two image files used to demonstrate the concept of perimetric complexity ('SI6_PC_test_files_Herskindetal2025')
