classification of movement Flashcards
what is active (endogenous) movement and examples
movement resulting from muscular contractions
-voluntary movements
-reflexes
what is passive (exogenous) movement and examples
movement resulting from external forces
-gravity
-supportive device
-other person
types of endogenous actions
reflex and voluntary
what is a reflex
involuntary and relatively stereotyped response to a specific stimulus
-involves specific unchanging neural network
what are the characteristics of reflexes
-fast
-standardized/stereotyped - similar each time
-involuntary
-response determined by stimulus
-innate
-usually protective function
what is a voluntary action
action resulting from higher order (cognitive) processing
-involves flexible variable neural network
characteristics of voluntary action
-slower
-adaptable/can be novel
-voluntary
-response related to stimulus not determined by stimulus
-learned
-can be protective or harmful
what are the 2 definitions of motor skill
task perspective: a specific type of action
performance proficiency perspective: level of skill
components of task perspective skill classification
1.size of muscle groups involved
2.task organization
3.predictability of environment
muscle group skill classification
related to precision
-gross skill - large muscle groups
-mixed skill - large muscles but precise
-fine skill - small muscle groups
task organization skill classification
-discrete - single action
-serial - set of actions
-continuous - continual action
environmental predicability skill classification
-open - effected by environment
-closed - not effected by environment
components of performance proficiency perspective skill classification
- maximum certainty
-efficiency of energy
-efficiency of time
what is capability
persons potential to achieve success at a task
stages of performance and learning
early, middle, late
