Q

What are continous vs discrete skills?

A

Continuous Skills:
- Actions without a clear start or end, often ongoing and fluid (e.g., swimming, running).

Discrete Skills:
- Actions with a clear beginning and end, performed as single units (e.g., throwing a ball, flipping a switch).

Q

Why do we care about defining and categorizing skills?

A

The type of skill impacts:
1. What and how we measure it
2. How we might give instructions
3. Theories of motor control and learning

Q

What is a Skill?

2 Defenitions

A

Skill as an ACTION or TASK (noun) – Task perspective

  • A goal-directed task or action
  • e.g. “Serving is a skill essential to playing tennis.”

Skill as an indicator of ABILITY (adjective) – Performance perspective

  • Ability to bring about some i) pre-determined end result with ii) maximum certainty & iii) minimum outlay of energy /time”
  • e.g. “Serena Williams is highly skilled at serving.”

Q

What are the 4 Criteria of a Motor Skill?

A
  1. Goal-oriented (different to movements, goal not necessary)
  2. Movement must be voluntary (not reflexive)
  3. Body and/or limb movements are required to accomplish the goal (different to cognitive skills)
  4. Result of practice. Needs to be learned/relearned

Q

What are Fine and Gross Motor Skills?

A

Size of Primary Musculature Required

Fine Motor Skills:
- Greater control of small muscles
- typically precise/ manipulative skills

Gross Motor Skills:
- Use of large musculature
- less emphasis on precision

Because many motor skills require a coordination of large and small muscles, it is better to think of these two skill types as ends of a continuum…

Q

What is a Closed Motor Skill?

A
  1. Stable, predictable environment
  2. Object does not change during performance
  3. Self-paced. Performer controls the situation
    * Object is acted upon
    * Context does not change

Q

What is an Open Motor Skill?

A
  1. Unpredictable, changing environment
  2. Object or context is in motion during performance
  3. Externally paced. Performer responds to variations in environment
17
Q

Why would baseball be considered an Open Motor Skill?

How could you make it more of an closed skill?

A

Consider a baseball player hitting a ball. The ball is in motion, you don’t know if that baseball will curve left or right, which makes the skill an open one. When things are in motion (externally paced), there is more unpredictability

Playing Tee Ball would make it a closed skill

18
Q

Why are environments seen as on a spectrum?

A
19
Q

Summary and critical questions to ask
to help classify motor skills

A

Skills can be classified depending on muscles involved, whether they are short or repetitive (organization) and their stability/predictability

  1. Could the action be performed whilst the large musculature was constrained?
  2. Is there a clear beginning and end to the movement (or movement components)?
  3. Does the performer initiate the action (selfpaced) or respond to the environment - which has unpredictability?
