Chapter 1 Flashcards
Information Processing model
Closed skills and Open skills are on a continuum. Please describe the environment on this continuum
Open skills have a unpredictable environment
in the middle there is a semipredictable environment
Closed skills have a predictable environment
Example of a Closed skill
typing, gymnastics, shooting a free throw
Example of a Open Skill
Playing football, soccer, wrestling
Example of a skill in the middle of the open to closed spectrum
Nascar driving, steering a car, playing chess
Discrete-Serial-Continuous Skills are on a __________________. Describe it.
Continuum
On one end is discrete skills that have a distinct beginning and end.
In the middle are serial skills. these are discrete linked together.
On the end is continuous skills and these actions have no discrete beginning or end.
Examples of Discrete
Throwing a dart
Shooting a gun
Flipping a light switch
Examples of Serial
Gymnastics routine
Assembly line work
Hammering a nail
Example of Continuous
Steering a cart
swimming
running
tracking a task
The Information Processing Model uses what 3 processes?
- Executive System
- Effector System
- Feedback System
Skills different than movement because
movements don’t necessarily have a specific goal. For example, I might be able to wiggle my arms but it doesn’t achieve anything - I need to be able to do this to swim though. So the movement helps me with this skill.
If someone is said to be a ‘skilled shooter’ or a ‘skilled player’ it means
That person is able to perform the goal with maximum certainty
what does it mean to perform a skill with
“maximum certainty”
They can reliably achieve their goal. You were a skilled 3 point shooter because you could be relied on to score for your team. I was certain you would score almost always. I was almost certain you would make the shot
Skills involve achieving some well defined goal by:
1.
2.
3.
Skills involve achieving some well defined goal by:
1. maximize certainty that you achieve the goal
2.minimize physical and/or mental energy required to do it
3.minimized time used
Critical elements to almost every skill:
1.
2.
3.
Critical elements to almost every skill:
1. perceive or notice the environmental info needed
2.DEcide what to do, where and when to do it
3.Organize muscular activity to generate the movements to achieve the goal
A major problem for the study of skills is….
example of this problem
is the fact that the several components of skill are studied by widely different groups of scientists, often with little overlap and communication among them.
ex: neuroscientists study senses and perception involved in skills while another group of physio therapists might be studying muscles involved in a movement so the two groups don’t combine their research even though both are required for the skills to be performed.
