LECTURE 15 Flashcards
Skill
A learnt ability to move more effectively and more efficiently
Synaptic pruning
Neurons that are unecessarily activated are elimated to increase neural efficiency
Long term potentiation
Improved efficiency within the motor system, increases strength/connection between synapses.
Myelination
Maturation of certain nerve cells whereby a fatty sheath forms around the axons which allows nerve impulses to travel faster
Selective inhibition
The ability to shut off one pathway and allow another to keep operating.
What does a skill LOOK like?
- Accomplishment of task goal
- Consistent
- Persistent
- Adaptability
- Efficient
Skill requires
- Perception
- Intention to move
- Postural control
- Coordination
Fitts and Posner 3 stages of learning
Cognitive, Motor, Skilled
Fitts and Posner - Cognitive stage
Pattern muscle behaviour together, trial and error
Fitts and Posner - Motor stage
Coordination stage, less errors, more relaxed
Skilled
Automatic, Fluid, Efficient, Accurate, Consistent
Learning
Result of permanent change, not observable, must monitor performance over a long period of time
Performance
Temporary, nonpermanent changes, observable
Performance improvement is a good indicator if…
- Assessed over long period of time
- Combined with other factors (consistency, persistence, coordination stability)
Performance improvement is a bad indicator if…
- The performance measure doesn’t truly show the gains
- Improved performance is a result of acquisition of bad habits
