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.

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.

Learning:• Sessions:• Introduction to technology.• Demonstration.• Practice with input.
• Practice:• 8 hours/month.• Recorded via forms.• Amount of time.• Technology.• Instruction.• Success.

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

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. C. 2010: Evidence for learning and skill transmission in Clovis blade production and core
