Q

non-regulatory environmental constraint

A

may affect performance, but movement does not have to conform (distracted)
ex: low lighting doesn’t change or affect the way you walk

Q

Continuous

A

The end point of the task is not an inherent characteristic to the task but is decided arbitrarily by the performer

Ex: walking, running

Q

Motor learning

A

study of the acquisition and/or modification of skilled action

25
Q

motor performance

A

temporary, nonpermanent change in the ability to execute a motor skill
-occurs during a practice session

26
Q

motor learning

A

relatively permanent change in the ability to execute a motor skill as a result of practice or experience
-occurs over a longer period of time

27
Q

stages of motor learning

A
  1. cognitive
  2. associative
  3. autonomous
28
Q

cognitive

A

-learner develops understanding of the task
-tends to have significant improvements in performance over a short time
-“what to do” decision

29
Q

associated

A

-learner refines movement with less errors and more temporal and spacial organization
“how to do” decision
-improvements occur more slowly

30
Q

autonomous

A

-learner continue to refine movent, high level of spacial and temporal organization and movement is relatively error free
-“how to succeed” decision
skill becomes more automatic with minimal cognitive thinking

31
Q

feedback

A

includes all sensory information that is available as the result of a movement that a person has produced

32
Q

2 types of feedback

A

intrinsic
extrinsic

33
Q

intrinsic feedback

A

sensory cues that come to the individual as a normal result of the movement
ex: vistibular, visual, proprioceptive, and sensory signals

34
Q

extrinsic feedback

A

not usually received during the movement
-ex: verbal cues, visual cues (mirror, video) tactile cues, auditory cues

Includes internally and externally focused verbal cues

35
Q

feedback parameters

A

scheduling vs intensity

36
Q

scheduling of feedback

A

includes concurrent and terminal

37
Q

concurrent feedback

A

during the movement

38
Q

terminal feedback

A

after the movement can be either delayed or immediate

39
Q

intensity of feedback

A

can be constant, summed, faded, or bandwidth

40
Q

constant feedback

A

after every trial

41
Q

summed feedback

A

after a set of trials

42
Q

faded feedback

A

initially every trial, then less often

43
Q

bandwidth feedback

A

feedback only when there is an error

44
Q

blocked feedback

A

one source of feedback (ex: same segment each trial)

45
Q

variable feedback

A

multiple sources of feedback (eg different segments on successive trials)

46
Q

Terminal Verbal feedback includes

A

knowledge of results– about the outcome of the movement (Eg: you jumped 2 inches further, you lost your balance 3 times)

knowledge of performance–feedback related to the movement pattern used to achieve the goal (eg you didn’t straighten your knee all the way, your knee collapsed in on the way down)

47
Q

Practice Conditions- spacing
(massed vs distributed)

A

massed- rest time less than practice time (more practice)

distributed-practice time equal to or less than rest time (more rest)

48
Q

practice conditions– variability
(constant vs variable)

A

constant-skilles practiced in constant conditions

variable-skills practiced in various conditions (ex: practicing sit-to-stand out of car)

49
Q

practice conditions– practice order

(blocked vs random)

A

blocked- one task performed repeatedly

random- variety of tasks ordered randomly

50
Q

practice conditions – strategies

(part/ whole vs mental)

A

part/ whole- component parts practiced prior to whole task

mental practice- task is imagined or visualized

51
Q

transfer

A

how well training transfers to a new task or new environment

way to measure motor learning

52
Q

motor learning

A

study of acquisition or modification of movement in normal subjects

53
Q

recovery of function

Recovery vs compensation

A

reacquisition of movement skills lost through injury

recovery-achieving function through original processes

compensation-alternative behavioral strategies are adopted to complete task

54
Q

direct (restorative)

A

resolution of temporary changes and recovery of the injured neural tissue itself
- nearby neural tissue taking over identical neural functions-leads to restitution of function

55
Q

indirect (compensatory)

A

completely different neural circuits enable the recovery of impaired function
-includes function- enabling and function-disabling plasticity

56
Q

Intracellular Neuroplasticity (CNS)
Denervation Supersensitivity-

A

postsynaptic membrane of a neuron become hyperactive to a released transmitter substance

57
Q

unmasking of silent synapses

A

recruitment of previously silent synapses

58
Q

neural regeneration (regenerative synaptogenesis)

A

injured axons begin sprouting
-limited ability in CNS
- primarily occurs by PNS
