Skills and Attention
Playing basketball is an example of this type of skill.
What is Open Skill?
This information processing stage analyzes the environment and determines if a stimulus has been presented.
What is Stimulus Identification?
Provides information about the state of the body itself and in relation to the environment.
What is Proprioception?
Open-loop control seems especially important when the environment is this.
What is Predictable/Stable?
A pre-structured set of movement commands that defines and shapes the movement.
What is a Motor Program?
A skill that has a easily defined beginning and end with a brief duration.
What is Discrete Skill?
In Activity 1, when the color of the text matched the word, was an example of this.
What is Stimulus-Response (S-R) Compatibility?
Provides information to the processing system about the state of the environment.
What is Exteroception?
This part of the closed-loop system carries out the action.
What is the Effector?
This theory consists of stored patterns that are adjusted at the time of execution.
What is the Generalized Motor Program (GMP) Theory?
When sensory information can be processed at the same time as other information without interference.
What is Parallel Processing?
Any factor that increases the duration of 1 or more stages on information processing will lengthen this.
What is Reaction Time?
This visual system is provides information about the "what" and is important for movement planning.
What is the Ventral Stream?
The open-loop control system lacks this.
What is Feedback?
The Motor Program Theory has these 2 problems.
What are a Storage problem and Novelty problem?
Focusing on the finish line during a sprint is an example of this type of focus of attention.
What is External Focus?
This important performance measure indicates the speed and effectiveness of the information processing stages.
What is Reaction Time?
This proprioception receptor senses muscle tension or force.
What are Golgi Tendon Organs?
A closed-loop system would be less effective for guiding this type of skill.
What is Discrete Skill?
These make a pattern appear the same time after time even when parameters changes. You might see this with writing style.
What are Invariant Features?
Often occurs when there is a change in one’s focus from a more automatic and external focus to a more internal focus such as how to perform the movement.
What is Choking?
This part of the closed-loop system contains the 3 stages of information processing.
What is the Executive?
This part of the closed-loop system that compares the anticipated sensory feedback with the actual sensory feedback.
What is the Comparator?
This control system would be more effective for walking across a balance beam.
What is Closed-Loop Control?
Similar to motor programs, this concept is used to describe simple, genetically defined activities such as locomotion, chewing, breathing.
What are Central Pattern Generators (CPG)?
