Skill Acquisition in Flaked Stone Technologies: Role played by aptitude, practice and teaching. Archaeological signatures. Understanding of a task vs physical ability to carry it out. How this relates to evolution of modern human brains and intelligence. Photo: Whitlock 2011
The Learning to be Human Project: Leverhulme Trust funded project. Skill acquisition and early hominid cognitive processes. 3 Strands: Emory University, Dietrich Stout – fMRI scans of experimental knappers. UCL, Stuart Page and James Steele – transmission chain design. Exeter – experimental study of flintknapping skill acquisition. Linked by focus on Oldowan, Acheulean and Levallois technologies. Use of same group of experimental knappers.
Study Group: 16 people. 3 groups – core, wider beginners and wider experienced. Core: Intensive training. Contact with artefacts. Brain scans. No previous knapping experience. Wider Beginners: Less intensive training – focus on practice. No previous experience. Based at Exeter Wider Experienced: Less intensive training – focus on practice. Range of experience levels. Not all based at Exeter
Aptitude: Spatial Ability Tests. Importance of visuospatial representations – Stout et al. 2008. Questionnaires: Age Sex Practical craft experience Contact with flaked stone assemblages Knapping experience Motor Ability Tests – Core only: Importance of fine finger movements and object manipulation – Stout and Chaminade 2007, Stout et al. 2008.
Evaluation: Skill assessed at regular intervals. Score 1-5 for connaissance (knowledge). Score 1-5 for savoir-faire (know-how). Flakes, cores and tools analysed.
Porcelain Cores: Mouldable Similar fracture properties to flint Consistent material Readily available Comparatively inexpensive Allows for greater reliability of results Photos: Khreisheh 2012, Whitlock 2012.
Skill Levels: Attempt to assign skill level to performance and products. Previous research 2-4 different levels. Lohse 2010: Beginner Adept Crafter Expert Based on amount of knowledge and know-how.
Why? Current interest in knapping skill identification: Identification of individuals. Identification of children. Need for longer term studies: Previous studies focus on single knapping sessions. Need for larger number of participants in studies. Skill acquisition across technologies. Oldowan, Acheulean handaxe and Levallois core. Skill acquisition as a factor in human cognitive development. Focus on early technologies Integration of study of learning process with study of brain scans.
Summary of results: High-level skill is not simply a result of number of hours practised. Natural aptitude and teaching have a very important role in skill acquisition Connaissance and savoir-faire are related in a more complex way than generally understood. Further work will look at the archaeological signatures and cognitive implications of this. References: Lohse, J.
