Q

when measuring learning, what are we interested in and why

A

their underlying capability/capacity for performance
-on any given occasion, the learner might not for various reasons perform up to their capability/skill level

Q

what factors improve the capability for skilled performance when it comes to learning give an example that would not be considered one of these factors

A

factors related to practice or experience
-performance capabilities of children increase as they mature and grow, but this is no evidence of learning cause it is not related to practice

Q

during practice there are many alterations to what nervous system and what do some refer to this as and explain

A

Central nervous system
“brain plasticity”
-plasticity refers to a brain that is changeable under various conditions which helps establish relatively permanent changes in movement capability (practice will continue to maintain neural pathways)

Q

difference between expert and beginners motor program

A

25
Q

better at assessing (perceiving) what play is happening is an improvement with practice in what parts of the conceptual model

A

stimulus identification and response selection

26
Q

being able to execute movment as planned is an improvement due to rpactice for what part of the conceptual model

A

motor program

27
Q

being better able ot make corrections to movement is an improvement due to practice of hwat part of the conceptual model

A

quality of feedback and comparator

28
Q

what is the performance curve and what is this used for

A

performance/time
-used to infer if learning has occured (but does not measure learning)

29
Q

what are 3 limitations of the performance curve

A
  1. performance curve does not = learning curve
  2. between-subject effects are masked
  3. iwthin-subjects variability are masked
30
Q

the shape of the performance curve depends on what

A

how you measure performance

31
Q

what is the law of practice

A

improvement is steep at first and more gradual later
-performance curve
-rapid improvements at beginning but eventually slows down
-still learning but changes in performance are decreasing

32
Q

what is the ceiling affect in the performance curve

A

test is so easy that everyone does well

33
Q

what is the floor affect in the performance curve

A

most/none will have any success

34
Q

what are the ceiling and floor affect useful for in the performance curve when it coems to measuring learning

A

help adjust assessment based on skill level

35
Q

what is the most common and traditional way to evaluate learning progress during practice

A

performance curves

36
Q

what are performance curves

A

plots individual or average performance against practice trials to evaluate learning progress

37
Q

what is one of the main reasons for suing performance curves and what is te drawback of this

A

they average out the discrepan performances of different learners
- this hides any differences between people (individual differences)
-gives impression that all subjects improve at same rate or way (which is not true)

38
Q

describe the within-subject variability in performance curves

A

-performance fluctuations within a single person tend to be obscured by the averaging process
-easy to assume that the learning process is going smoothly and gradullay however for each point on the curve represents an average of x amount of trials which is another average of the participants

39
Q

what are the 3 effects practice can have on the learner

A

-relatively permanent effects that persist across many days, even years
-temporary effects that vanish with time or a change in conditions
-simultaneous temporary and relatively permanent changes that can noticeably influence performance

40
Q

whenever learners practice and especially when they get instructions and feedback, what is important to have

A

a way to separate the relatively permanent practice effects from the temporary effects
(example if you can use a tool to help practice but cannot use during performance, important to practice without that tool at some point)

41
Q

why does our performance on a given day, not necessarily equal our capability to perform a skill

A

because performance will still fluctuate due to performance variables
-alertness
-fatigue
-motivation

42
Q

what are 4 defining features of performance

A

-observable behaviour
-may or may not be due to learning
-temporary
-may be influenced by performance variables

43
Q

what are 5 key features of learning

A

-improvement
-consistency
-stability
-persistence
-adaptability

44
Q

performance improves over what

A

time

45
Q

what are 3 ways you can define improvement in learning

A

-speed
-accuracy
-movement quality

46
Q

experts are able to _____ execute their skills at a high performance level

A

reliably

47
Q

stability in performance refers to what and give examples

A

resistance to perturbations (May be internal or external)
INTERNAL
-distractions
-choking
EXTERNAL
-wind
-weather

48
Q

persistance in performance refers to what and how can measure this

A

improved performance lasts over longer and longer periods of time
-retention test

49
Q

adaptability in performance is also known as what and what does this refer to, how can this be measured

A

generalizability
-performer can adapt to a variety of contexts and maintain skill improvement
-transfer tests (measure performance on related test to show what youve learned)

50
Q

adaptability is related to what other key factor of learning

A

stability

51
Q

retention and transfer tests help us measure what in learning and performance

A

infer if have persistance and adaptability

52
Q

what is the idea behind transfer designs

A

can analyze whether a change that improves performance in practice also improves learning by separating the relatively permanent and temporary effects of a variable

53
Q

what does transfer test refer to

A

a change of task conditions

54
Q

what does retention test refer to

A

a test given after an empty period without practice

55
Q

what is the logivce behind a transfer or retention test

A

if temporary effects have dissipated by the time of the test and any temporary effects are not allowed to reappear, then any differences observed in the delayed test should be due to the relatively permanent effects aquired through training (learning)

56
Q

when there is an increase risk during performance what is needed

A

an increase for simulations
-med students
-firefighters
-pilots

57
Q

what is the idea behind the saying, never truly a blank slate, when it comes to learning

A

past experiences are always relevant and can be used in the learning process

58
Q

what helps the increase of transfer between skills

A

similarity

59
Q

what is transfer of learning

A

when practice on one task contributes to performance capability on some other task
ex; rollerblading, ice skating

60
Q

transfer learning can be helpful for what type of skills and not so helpful for what

A

HELP
-serial or continuous skills
-can be broken down intor elements for practice
NOT
-discrete
-too fast

61
Q

what are the different types of transfer learnign

A

specific and generalized
