Skills Concepts
Playing basketball is an example of this type of skill.
What is Open Skill?
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?
This is used to assess how quickly a person can initiate a required movement.
What is RT?
A skill that has a easily defined beginning and end with a brief duration.
What is Discrete Skill?
These send neural impulses from the body to the CNS.
What are Sensory (Afferent) Neurons?
The compared to the closed-loop control system, the open-loop control system lacks this.
What is Feedback?
This theory consists of stored patterns that are adjusted at the time of execution.
What is the Generalized Motor Program (GMP) Theory?
In Activity 2, when the color of the text matched the word, was an example of this.
What is Stimulus-Response (S-R) Compatibility?
This type of error measures accuracy or being off target.
What is absolute error (AE)?
This visual system provides information about the "what" and is important for movement planning.
What is the Ventral Stream?
A closed-loop system would be less effective for guiding this type of skill.
What is Discrete Skill?
In motor program theory, 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?
A batter responding to a pitch is an example of this type of reaction time.
What is discrimination RT?
Based on Fitts' Law, give an example of something that would increase MT in a rapid aiming task.
What is increasing D, reducing W, or both?
This proprioception receptor senses muscle tension or force.
What are Golgi Tendon Organs?
This concept in the dynamical system theory is the inextricable linkage between information specifying body, environment, and action control.
What is Perception-Action Coupling?
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)?
This law states RT increases logarithmically as the number of stimulus-response choices increases.
What is Hick's Law?
According to Schmidt's Law, increasing the MT will result in this.
What is increased movement variability (error)?
This brain structure is critical for movement initiation and the coordination of movements for fine motor skills.
What is the primary motor cortex?
This change in patterns of light rays striking the retina allows perception of motion, position, and timing.
What is Optical Flow?
This is concept of the dynamical systems theory that exerts compression of multiple degrees of freedom of the system.
What is Order Parameter?
Give 2 examples that will increase RT.
