Understanding the diversity of human cognitive traits in different cultural contexts and in an evolutionary framework is crucial for advancing actual human mind but also its disorders. Attention and executive control including traits such as inhibition, impulsivity, and hyperactivity, are studied in WEIRD (Western, Educated, Industrialised, Rich, and Democratic) societies, where sustained focus and impulse control are highly valued. A deficit in these domains might lead to a diagnosis of a mental disorder such as ADHD (Attention Deficit Hyperactivity Disorder).

Around 1,200 years ago, archaeological evidence suggests pre-existing pastoralist societies that had been present in some parts of eastern Africa since c. 5,000 BP experience significant cultural and economic change. Materials signs of these include the uptake of iron smelting technologies, new ceramic styles, and changes in food production. In the following centuries, the region also experienced several significant shifts in climate, alternating between periods of increased rainfall and extended droughts.

This project is a response to calls to build long-term sustainability and resilience into pastoral social-ecological systems in sub-Saharan Africa through provision of deep histories of human-environment interactions. It focuses on collecting and analysing archaeological and related data on the responses of pastoralist communities inhabiting the Laikipia and Leroghi plateaus, northern Kenya, to cycles of extreme drought and enhanced rainfall over the last millennium.
