Name the term: a) A task that has specific purpose or goal to achieve b) Indicator of performance quality
What is a skill?
100
What are the 3 methods of one dimension classification of motor skills? Hint: S___, S_____, S_____
1. Size of Primary Musculature 2. Specificity of Where Actions Begin and End 3. Stability of the Environment Size- Specificity- Stability
100
What are the two dimensions of Gentile's Taxonomy?
1) Environmental context (the number) 2) Function of the action (the letter)
100
What is the speed accuracy trade off?
when performers attempt to do something more quickly , they typically do it less accurately
100
With Kinematic measures we usually measure:
Displacement velocity acceleration
200
Require body, head, and or limb movement to achieve its goal-are learned or re-learned
What is a motor skill?
200
Name the term: • defined beginning and end points • often requiring a simple movement • flipping a light switch
What is Discrete motor skill?
200
What are the subsections of the Environmental context? And what do they mean?
A. Regulatory Conditions i) Stationary or closed skills ii) In motion open skills   B. Variability i) no intertrial or ii) intertrial
200
What are 3 performance outcome measures?
What is error, speed, and movement magnitude?
300
behavioral characteristics of a specific limb or a combination of limbs that are component parts of an action or motor skill
What is a movement?
300
Name the term: • arbitrary beginning and end points • repetitive movements
What is Continuous motor skill?
300
What are the subsections of the Function of the action?
A) .body stability/orientation i) Body Stability or ii) Body Transport object manipulation i) No Object or ii) Object Manipulation
300
Traffic lights are an example of what kind of reaction time?
What is Choice?
300
Which brain imaging technique creates virtual lesions?
What is TMS- Transcranial magnetic stimulation?
400
Measuring _______ involves: • Numeric Outcomes • Measurement of the Goal (eg.distance of a long jump, height of a high jump, how fast ran, how far ran)
What is motor skills? Measuring Movement involves: • Specific characteristics • Measurement the limb
400
In a _____ __________, the performer determines when to begin the action. AKA. the action is SELF-PACED
What is a closed environment?
400
Give me an example of a 4D action and break it down into its two dimensions.
• 4D Dribbling a basketball against defenders • environmental context is in motion, high intertrial variability, both body transport and object manipulation required.
400
What is Discrimination reaction time and give me an example.
when you have multiple signals, only 1 commands 1 response
400
What is relative phase?
Talking about coordination. It is : the relationship between two limbs at a specific point in the cycle Give me an example of an in-phase and anti-phase movement.
500
What are the 3 reasons for distinguishing between motor skills vs. movement?
1. People LEARN motor skills and actions 2. People ADAPT movement characteristics to achieve a common goal 3. EVALUATE actions and movements with different types of measures
500
What am I talking about? Supporting surface Objects involved Other people involved
What is the Environmental context?
500
Give me an example of a 3B action and break it down into it's dimensions.
3B Body stability Object manipulation Regulatory conditions in motion no intertrial variability walking on a treadmill at a constant speed while reading a book catching a series of softballs thrown at the same speed by a pitching machine.
500
What are the 5 steps of movement planning?
stimulus identification memory store response selection effector output/force movement execution
500
How do we measure error for continuous actions? And what does it measure?
use Root-mean- squared error (RMSE) Error b/w the desired pathway and the actual pathway indicate the amount of error b/w the performance curve produced and the criterion performance curve for a specific amt of time during which performance is sampled
