kid-knapping

Research compendium for 'What lithics can tell us about the evolution of learning and development' (Archaeometry).

Getting Started

Please open the Rproj file instead of the Rcode directly to make sure relative paths work!

File Structure

The repository is organised into four main directories: analysis, data, and figure.

code

• analysis.R ... This is the R script generating the main results and figures of the experiment, especially the multi-level model of knapping performance.

data

• individual__data_by_participant.csv... This csv file documents relevant attributes, particularly motor and psychometric test results, at the individual research participant level.
• lithic_data_by_core.csv... This csv file documents morphological and technological attributes of lithics at the core level.

figure

• Fig1.jpg ... This is Fig.1 in the manuscript.
• Fig2.png ... This is Fig.2 in the manuscript.
• Fig3.png ... This is Fig.3 in the manuscript.
