cultures: (BACT) to all material cultures: A Two-Part Approach 1 Observational Learning of Knapping Choices: 1. Observational Learning of Knapping Choices: − Which emic choices of the artisan are visible as etic observations by the learner? − Which observations of the learner are also etically observable by the archaeologist? 2. How does dual inheritance work in foraging societies?: 2. How does dual inheritance work in foraging societies?: − Where and when are foragers enculturated? − Where and when do they witness technological performances that affect their adoption of performances that affect their adoption of technological choices? − What is the structure by which individuals encounter their Inclusive Inheritance (in NCT terms)?
the Assemblage Blank Production Choices at the Assemblage Level • Platform Maintenance: Platform Treatment E terior Platform Angle Tactical choices for each flake Exterior Platform Angle Platform Thickness • Dorsal Surface Convexity: L th/ idth ti L it di l t t f th f d Tactical choices for each flake Strategic choices for each core Length/width ratio: Longitudinal extent of the surface removed Width/thickness ratio: Vertical convexity of the mass removed Lateral edge type: Longitudinal shape of the surface C i b f d l id d fi i h i Cross-section type: Number of dorsal ridges defining the convexity Profile type: Curvature of the core surface removed • Core Modification: Core Orientation: extant core morphology Core Convexity Management: refits, diagnostic reparations. • Direction of Core Exploitation: (the only true “sequence model” aspect) Early Exploitation: Dorsal scar patterns of debitage vs. blank length. Late Exploitation: Dorsal scar patterns of debitage vs. blank length.
