Motor control
|
Area of study that deals with neural, physical, and behavioral aspects of movement.
|
|
| 2 |
Motor Learning
|
Area of study focusing on the acquisition of motor skills as a result of practice
|
|
| 3 |
Motor Development
|
Area of study concerning changes in motor behavior as a result of growth, maturation, and experience.
|
|
| 4 |
Franklin Henry
|
Father of motor skills research, examined gross motor skills
|
|
| 5 |
Discrete
|
Well-defined beginning and end; action is usually brief
|
|
| 6 |
Serial
|
several discrete actions combined to a sequence
|
|
| 7 |
Continuous
|
No recognizable beginning or end, often repetitive activity
|
|
| 8 |
Motor
|
Movement success is primarily determined by quality of movement, less emphasis on perceptual...
|
|
| 9 |
Cognitive
|
Decision making is important, nature of movement is of minor importance.
|
|
| 10 |
Open
|
Variable, unpredictable during action
|
|
| 11 |
Closed
|
stable, predictable
|
|

1: 3 stages of learning
|
1. Cognitive stage (early learning) "verbal stage" Getting an idea of movement
|
|
| 13 |
2: 3 stages of learning
|
2. Associative stage (Intermediate stage): refining, modifying, adapting movement pattern
|
|
| 14 |
3: 3 stages of learning
|
3. Autonomous stage (Late learning) "motor stage": Automatic movement production, low attention...
|
|
| 15 |
Motor unit
|
Muscles are activated by motor neurons. Motor neuron and muscle fibers it innervates.
|
|
| 16 |
Afferent (sensory neurons)
|
Carry messages to brain/spinal cord
|
|
| 17 |
Efferent (motor neurons)
|
Carry messages from brain/spinal cord
|
|
| 18 |
Interneurons
|
Originate and end in brain/spinal cord
|
|
| 19 |
Cerebellum
|
Balance, fine motor control. Autopilot of the brain
|
|
| 20 |
Declarative memory
|
memory about facts and events
|
|
| 21 |
Procedural memory
|
Memory for sequences of events, processes, and routines.
|
|
| 22 |
Trace decay
|
Dont use info in a while
|
|
| 23 |
Interference
|
replace old info with new info.
|
|
| 24 |
Focal (cognitive) vision
|
concerned with events in central vision
|
|
| 25 |
Ambient (motor) vision
|
available for entire field of vision (central, peripheral)
|
|
| 26 |
Proprioception (kinesthesis)
|
Perception of body parts, their movements and positions.
|
|
| 27 |
Vestibular system
|
Located in inner ear. a) provides info about position of head with respect to gravity. b) is...
|
|
| 28 |
Proactive interference
|
Source of forgetting caused by learning that occurred before the learning of something new
|
|
| 29 |
Rectroactive interference
|
Source of forgetting caused by learning that occurred after the learning of something new.
|
|
| 30 |
Hick's Law
|
Reaction time increases by a nearly constant amount as the number of S-R alternatives is doubled...
|
|
| 31 |
Psychological refractory period
|
The delay in a person's reaction time to the second of two closely spaced stimuli compared...
