Paper published on cumulative culture in Royal Society Journal Proceedings B
Social Mind Center researchers Helena Miton and Mathieu Charbonneau publish a paper titled "Cumulative culture in the laboratory: methodological and theoretical challenges" in Proceedings B of the Royal Society.
The paper discusses how in the last decade, cultural transmission experiments (transmission chains, replacement, closed groups, and seeded groups) have become important experimental tools in investigating cumulative cultural evolution, the process by which traditions are gradually improved upon over time, leading to solutions that no single individual could have invented on their own. The authors detail several mismatches between theoretical definitions of cumulative culture and their experimental implementation, mainly (1) unbalanced allocation of time between conditions, and (2) complexity of the tasks used. Finally, they introduce a new methodological tool, design spaces, as a way to study variation in such experiments.
