The archaeology of the social brain revisited: rethinking mind and material culture from a material engagement perspective.

The social brain hypothesis (SBH) has played a prominent role in interpreting the relationship between human social, cognitive and technological evolution in archaeology and beyond. This article examines how the SBH has been applied to the Palaeolithic material record, and puts forward a critique of the approach. Informed by Material Engagement Theory (MET) and its understanding of material agency, it is argued that the SBH has an inherently cognitivist understanding of mind and matter at its core. This Cartesian basis has not been fully resolved by archaeological attempts to integrate the SBH with relational models of cognition. At the heart of the issue has been a lack of meaningful consideration of the cognitive agency of things and the evolutionary efficacy of material engagement. This article proposes MET as a useful starting point for rethinking future approaches to human social cognitive becoming in a way that appreciates the co-constitution of brains, bodies and worlds. It also suggests how MET may bridge archaeological and 4E approaches to reconsider concepts such as the 'mental template' and Theory of Mind. [ABSTRACT FROM AUTHOR]
