Level 10 Coaching Flashcards
Self-organization vs. Prescriptive Coaching (Information Processing)
Self Organization: The athlete is allowed to find their own functional solution
Prescriptive Coaching: The coach gives the exact technique that the athlete needs to do in order to be successful
If an athlete is doing something you don’t like and you want them to do something different, what question can you ask yourself?
What can I add to practice that is going to make that current solution not effective?
*This is the whole idea of the Constraints Led Approach
Constraints Definition by Rob Gray
A feature of an individual, task, or environment which acts as an INFORMATIVE boundary in the solution space. (It constraints the possible coordination solutions that can be used while at the same time providing information and feedback that can guide the search for a more effective one.)
Whats is Bernstein’s Degrees of Freedom Problem? This is the single most important problem in motor control.
How can a system (the human body) with so many independent components (bones, joints, muscles, etc), which have countless combination possibilities, be controlled?
How do we convert the body into a controllable system?
How do we find a coordination solution?
Choice creates confusion.
When trying to solve the Degrees of Freedom Problem, what is the “Solution Space”?
The set of possible values (degrees of freedom) which the individual-task-environment could take for a particular movement problem.
When comparing an NBA player and 10 year old shooting jump shots (show picture), why do these two athletes have such different coordination solutions even though they have the same the goal of making a basket?
Constraints. Specifically a Task Constraint. The hoop is 10 feet high and the typical ball is a full size 29.5. This requires different movement solutions for each. The 10 year old must shoot with two hands and from their hip. The NBA player can shoot with hand without twisting body.
What are the 3 types of constraints (Newell’s model)
Task, Environment, and Individual
Coordination emerges from the interaction of what?
Constraints (task, individual, and environment)
We solve Bernstein’s Degrees of Freedom problem by reacting to….
Constraints. The constraints guide us to a particular area in the solution space.
Solving the Degrees of Freedom problem would be nearly impossible without what?
Constraints
As an analogy, if the Solution Space is a big open field, constraints could be seen as what?
A fence saying you can’t go over here.
How is Newell’s Constraint Model, the triangle of the 3 constraints (task, individual, environment), different from the Constraints Led Approach (CLA)?
Newell’s Constraint Model is a theory that can be applied to multiple types of coaching methods.
The CLA is a specific coaching method that manipulates constraints with a specific goal in mind.
Describe an Information Processing (IP) approach to skill acquisition (coaching) and how that relates to solution space.
This is when you give very specific instruction/technique for how to do something. It is prescriptive instruction.
In the wide open area of solution space, it would be like using fences (constraints) to make a very small box that would have a very limited degrees of freedom.
Describe an Environmental Constraint.
Features of the performance environment (not the individual) which constrain the coordination solution largely independently of the task being performed. It applies to any skill you try to do. If multiple sports were being played at a park, an environmental constraint would effect all of them.
Examples: temperature, wind, Light level, surface friction
Describe a Task Constraint.
Features of the performance environment (not the individual) which constrain the coordination solution dependent on the specific task being performed. If multiple sports were being played at a park and I brought a mini basketball to play basketball with, this would only effect the basketball players.
Examples: Rules, Equipment, size of the ball, # of players, size of the court, height of the basket, time allowed.
Describe an Individual Constraint
Features of the individual which constrain the coordination solution.
Two types of individual constraints:
1. Structural: characteristics of the body structure like height, flexibility, strength, weight
- Functional: behavioral characteristics that influence coordination like motivation, fatigue, attention.
The three types of constraints are interactive. Give an example.
If you play with a heavier basketball (task), the weaker player (individual) will have a harder time shooting from outside.
Definition of the Constraints Led Approach to Coaching and the 4 objectives you want to achieve with it. You may not have all of them perfectly, but the most effective CLA does all 4 of these.
Deliberately manipulating one or more constraints in practice in order to achieve one of these 4 things:
- De-stabilize an existing, non-optimal movement solution
- Encourage exploration and self-organization of a new movement solution. (This is the most important one. Constrain to afford.)
- Amplify information and invite affordances
- Provide transition feedback about progress toward a new, more optimal solution
When you de-stabilize a movement using the CLA, you want to move the system away from what?
The attractor location.
Define Attractor
locations/states the system (person) tends to gravitate towards.
Define Transition Feedback which is one of the 4 objectives of the CLA
Information that relates directly to the change in the coordination solution that needs to occur at some future time in the learning process.
Not so much just telling you how you did but rather what you need to do next.
Not telling you what the solution is but rather whether you are looking in the right area.
Example: Playing hide and seek and giving clues of “hot” or “cold”. You are not saying exactly where the person is hiding.
*Giving people information about the effectiveness of the exploration.
When comparing the CLA vs. Prescriptive Instruction, explain the analogy of using 1 fence instead of 4 fences
In the big solution space, the CLA would put up one fence saying you can’t go over here, but you can explore this large are over there.
With Prescriptive Instruction, it would be like putting up 4 fences to form a cage and saying you must stay in this small space and you can’t go anywhere else to explore.
Constraints have been used for years by coaches, but what is different with the CLA is how you use the constraints and your intention. Explain the difference
Typically constraints are used based on the information processing approach to skill acquisition and using prescriptive instruction.
The CLA uses constraints to allow for self organization using the Ecological Dynamics approach to skill acquisition.
What are the two different ways we can view what skill is? Or, What are two ways we can see our transactions with the world?
Transactions because we can effect the environment and the environment can effect us.
Describe them.
Information Processing and Ecological Dynamics
- Information Processing: Treat the mind like a computer. You train to store up all these movement techniques so that they become automatic and you can use them at the right time. See-Take time to go thru your files of what to do-Then Act
- Ecological Dynamics: Movement is learned from the interaction of the individual, environment, and task. Perception-Action Loop
