The Dreyfus model of skill acquisition and developing trading expertise
As I have said earlier the key to success in trading is about developing procedural memory. Procedural memory is a long term memory for skills. It is implicit memory and as a result difficult to verbalize.
Procedural memories are muscle or thinking sequences which have been internalized by the brain and when required to perform a task the procedural memory kicks in and you can effortlessly do the task without being aware of steps. Procedural memory is also called skills memory.
The most well known psychological model of skill acquisition is called Dreyfus model. In 1980, two brothers working in the area of artificial intelligence and software were commissioned by the Air Force Office of Scientific Research (AFSC)to study skill acquisition. They submitted a report to AFSC titled " A five stage model of mental activities involved in skill acquisition".
Subsequently the model was published by them in a book Mind over machine: The power of human intuition and expertise in the era of the computer , in which they proposed a model of skill acquisition that argued that skill acquisition process is 5 progressive stages of development.
- Stage 1: novice
- Stage 2 : advanced beginner
- Stage 3: competent
- Stage 4 : proficient
- Stage 5: expert
