25
what is an example of motor time?
Once the decision is made, leg and arm muscles activate, leading to the first steps or swing.
26
what is movement time?
the time interval between the start of a movement and its completion (100m sprint)
27
what us absolute error?
the estimate of overall size of the error
28
what is constant error?
provides information on overall direction of error
29
what is variable error?
standard deviation of performance
30
what are kinematics?
motion qualities without regard to force (displacement, velocity, acceleration)
31
what are kinetics?
various internal and external forces acting on the body
32
what is electromyography?
electrical activity in the muscle
33
what is coordination?
spatial and temporal relationships of limb segments
34
what performance process measures are seen in a ballet spin?
coordination, displacement and acceleration
35
what performance process measures are seen in pole vault?
acceleration, velocity, internal + external force, coordination
36
how does the information processing model work?
1. sensory system detects environmental info 2. perceptual system organizes and classifies info 3. memory encodes and stores info 4. processor integrates perceptual memory information and makes a decision 5. response organization and effector mechanism send appropriate motor commands to muscles
37
what are the 3 layers of the eye?
sclera, choroid, retina
38
what senses colour in the eye?
cones
39
where is the highest concentration of cones found?
fovea centralis
40
rods and cones synapse with what?
bipolar cells
41
bipolar cells synapse with what?
ganglion cells
42
the axons of the ganglion cells form what?
optic nerve
43
light rays are refracted and bent as they pass through what?
cornea, pupil and lens
44
what is the function of the sclera?
maintain the shape of the eye
45
what is the iris?
a muscle
46
what do the aqueous and vitreous humor do?
refract light rays
47
what does the sclera do?
maintains shape of the eye
48
what does the choroid do?
contains blood vessels that nourish the eye
49
what does the retina do?
where the image of the optical system is formed
50
what does the cornea do?
gathers and focuses light
51
what does the pupil do?
hole in the iris that light filters through
52
what does the iris do?
controls size of pupil and amount of light entering the eye
53
what does the lens do?
bends the light entering the eye
54
what does the aqueous humour do?
watery fluid in small chamber behind cornea
55
what does the vitreous humour do?
watery fluid in large chamber of eye
56
what do rods do?
detect intensity of light
57
what do cones do?
detect colour of light
58
what is the fovea centralis?
densely packed photoreceptors
59
what is the optic nerve?
bundle of axons of the retinal ganglion cells as they exit the eye
60
what is the occipital lobe?
primary visual processing centre at the rear portion of the brain
61
what is performance?
observable behaviour
62
what is learning?
must be inferred from behaviour
63
how do we know learning has occurred?
-change over time -more consistent performance -change is relatively permanent
64
what happens during the cognitive stage of learning?
-lots of errors (gross errors) -highly variable performance -high cognitive involvement
65
what happens during the associative stage of learning?
-fewer errors -ability to detect own errors -basic fundamentals have been learned -decreased variability -cognitive shift to higher order components
66
what happens during the autonomous stage of learning?
-skill becomes automatic -little error -detect and correct errors
67
what is transfer of learning?
the influence of having a previously practiced skill on the learning of a new skill
68
what is positive transfer?
when the experience with a previous skill facilitates the learning of a new skill
69
what is an example of positive transfer?
speed skating to hockey
70
what is negative transfer?
when the experience with a previous skill interferes with the learning of a new skill
71
what is an example of negative transfer?
baseball to cricket
72
what is zero transfer?
when the experience with a previous skill has no effect on the learning of a new skill
73
what is an example of zero transfer?
swimmer playing piano
74
when is positive transfer most likely?
-when components of skills are similar (soccer and field goal kicking) -similarities in the learning process (same decision making required)
75
when is negative transfer most likely?
-changes in spatial location (run to 3rd base instead of 1st) -changes in timing (writing name with different timing)
76
how do you promote transfer?
-contextual interference (practice different skills in one session) -vary type of practice (punting football with and against wind) -reduce frequency of feedback (ability to detect and correct own errors)
77
what is task complexity?
number of parts in the task and the information processing demands
78
what is task organization?
how the components are interrelated
79
when should you do part practice?
when skill is high in complexity and low in organization
80
when should you do whole practice?
when the skill is low in complexity but high in organization
81
what is blocked practice?
task is practiced many times before next task
82
what is random practice?
ordering of tasks is randomized during practice
83
what conditions should remain constant during closed skills?
regulatory (size of hoop, height of bar)
84
what conditions should be varied during closed skills?
non-regulatory (crowd noise, fatigue)
85
what conditions should be varied during open skills?
regulatory (patterns of receivers, size of defenders) and non-regulatory (crowd noise, fatigue)
86
what is augmented feedback?
information about performance that comes from an outside source
87
what is knowledge of results?
information about the outcome
88
what is knowledge of performance?
information about the production of movement pattern
89
what is the purpose of augmented feedback?
-provides info for error identification and correction -acts as a form of reinforcement -serves to motivate learner
90
what is prescriptive verbal KP?
identifies error and tells learned how to correct
91
what is descriptive verbal KP?
describes error made
92
what is faded feedback?
when a coach or instructor gives a lot of feedback at the start of learning a new skill, but then gradually reduces it as the athlete becomes more skilled and confident.
93
what is bandwidth feedback?
when feedback is only given if the performance falls outside a set acceptable range (or “bandwidth”) of correctness.
94
what is summary feedback?
Instead of giving feedback after each repetition, the coach or instructor waits until the athlete has completed several trials, then provides a summary of their performance.
