These notes come from a 30-page long study titled "A Theory on the Skill-Performance Relationship" and looks at how skill and performance are entwined in various parts of life, but I'll keep it sports-related.
Part 1 today and part 2 tomorrow or Friday - strap in!
- It can be examined at the technical, behavioral, psychological and neurological levels
- Skill affects performance and performance in turn defines/affects skill
- Successful performers are successful not just because of their skills but because they take advantage of their skills by creating more occurrences of momentum, making them last longer and using them to bounce back faster from streaks of unsuccessful performance
- The variability of skill’s effect on performance becomes clear when considering the difference between skill possession and skill execution
- The possession of a certain level of skill does not automatically lead to invariant performance at that level because skill execution fluctuates as a function of how well/poorly individuals are able to use their skills during performance
- To better understand the skill-performance relationship, you need not only examine the effects of skill on performance but also the main determinants of skill (ability x effort in practice)
- Ability is the the innate capacity to understand/learn information from acquiring physical/cognitive skills as to acquire complex motor skills,you require a capacity to coordinate bodyparts/implements used in performance such as golfers being able coordinating their upper/lower segments for a smooth swing
- Skills are learned, acquired physically/mentally tools or qualities to execute certain actions required for successful motor/cognitive performance in specific domains – a learned ability to perform at a specific level from acquiring the necessary mental/physical know-how for doing so such as a golfer learning to hit iron clubs down into the ground to get the ball up in the air and for this to be a skill, you must be able to do it consistently
- A skillful golfer not only gets the ball up in the air almost every time but has also learned to regulate the ball’s flight trajectory on demand
- Effort is the employment of personal resources for practicing/improving skills via frequency, duration and intensity
- Performance is objectively/subjectively measuring performance in cognitive/physical tasks
- A golf handicap is a good example of the intersection where skill, ability,effort and performance all meet
- High ability individuals are more likely to benefit from personalised coaching/tutoring than those with lower abilities
- The best performers not only benefit from initially higher performance, but their rate of improvement is faster
- Ability limits the effects of effort/practice on skills where more practice in music does not correlate with better music skills/performance, suggesting a relative lack of musical talent restricts the beneficial effect of practice
- It is more difficult to compensate for a relative lack of ability in certain activities although there can be some compensation from added work but the theory of the path of least resistance suggests that people are less likely to engage in hard work when the required effort increases
- In addition to technical knowledge/physical skills in cognitive/motor areas of performance, mental skills are also required for best performance
- You need a model that assesses the contributions of ability/effort to the over skill/performance in both absolute and relative terms
- A golf score cannot be used as a proxy for skill as both need to be assessed individually
- Cognitive/physical abilities + psychological/physical effort = skill
- Working memory is an integral part of skill/performance in most cognitive/physical tasks as it enhances action-perception skills
- The positive effect of working memory on performance is diminished if a performer has not acquired requisite knowledge/actions (skills) through practice to deal with such interfering factors such as cognitive load
- The 4 cornerstones of skill-performance are neural functioning/nonconscious processing + behavioral execution + mental-social factors/conscious processing + ability/know how and skill performance is the result of all of them synergistically coming together
- A piano player must have the ability to play the music on their own but that doesn’t guarantee successful execution in front of friends or 1000’s of listeners which also depends on conscious processing of relevant mental (concentration) and social (audience presence) factors
- In cognitive/motor tasks, both technique possession for skills (the amount of relative knowledge possessed) and behavioral execution of skills are needed for the best performance
- In math tasks a person is more likely to be successful if they have a large repertoire of knowledge of relevant/basic math operations as well as an ability to think mathematically using their acquired knowledge
- In golf you need the knowledge of how to execute certain technical shots as well as the behavioral skill of how to use this technical knowledge in-game
- High performers have better technical, tactical and procedural knowledge then lesser skilled performers
- Performance variance (between individuals) is caused by a lack of proper technical knowledge, incorrect technical practice and failed execution of skill
- Unmastered skill leads to a more variable performance and worse outcomes
- Performers must also have the ability to retrieve the necessary knowledge from their long and short term memory storage
- The planning of a motor movement in the mind consists of retrieving a motor plan from the memory which has a signature similar to the actual execution of the plan
- If performance is not frequent enough then knowledge decays and the retrieval of critical information slows down with it and the skill then becomes fragile/variable and hard to reproduce at a high level
