Q

What are the 6 performance charctertistics that indicate learning? (you can derivie that you’ve had learning if these 6 are happening)

A

1) Improvement over time

2) Consistency - same or similar each time, less varibility - does the skill come out the same everytime you do it

3) Stability - less disturbance of the performance by internal and external perturbations (increased stability of the skill means that it is less affected by those perforamnce variables)

4) Persistence - performance capability contineus over time (i got from this point to this point w/ practice and i can maintain this level of perfomrnace moving forward)

5) Adabptability to a variety of performance contexts - generalizability - regardless of wahts happening, maybe im ona. different surface or have visual / auditory disturbances i can still adapt

6) Reduction of attention to the tasks demands (don’t even have to think about it)

Achieving these means we can say that motor learning has occured by looking at that motor performance

21
Q

KNOW: Period of transition between two phases of acquiring certain aspects of a skill can cause a palteau

Period of moor motivsation, time of fatigue / lack of motiviation can cause a plateau

Ceiling / floor effects can cause a performance plateau

A
22
Q

What is a floor effect?

A

test is so hard that it doesnt even represent your score

23
Q

What is a ceiling effect?

A

Test to easy and doesnt represent your actual score

24
Q

What are the 3 stages of motor learning?

A

1) Cognitive
2) Associative
3) Autonomous

25
Q

In what stage of motor learning does the BEGINNER focus on cognitvely oriented problems related to what to do and how to do it?

There are lots of mistakes, and errors are large in this stage

A highly variable performance

They need lots of help on how to improve and what to do

This is when they’re just wrapping their head around it

A

Conitive stage

26
Q

In what stage of motor learning does the person associate specific environmental cues with the movements required to achieve the goal of the skill?

There are fewer mistakes here and erroes are small

It is also called the refining stage

Decreased performance variability

Able to self-assess and identify some of own performance errors

A

Associative stage - they have a much better handle on the task now

27
Q

in what stage of motor learning has the skill become almost automatic or habitual

Person does not consicously think about the movement while perofrming the skill

easy for them to dual task

Performance variability is very small

Consistency from one perfomrance to the next is easy for them (adapitability)

Can detect many of their own errors and make proper adjustments without consciousness awareness

note much practice varibaility here (even lots of factors like stress don’t make them mess up)

A

Autonomous stage (auto)

28
Q

This is how they move through the sages of motor learning w/ expert being on the end

A
29
Q

Do the cognitive stage, assocaitive stage and autonomous stage take an even amount of time to get through

A

No, lots of variability

NOTE: We need practice to move from one stage to the next - and not everyone will take the same amount of time in each stage

30
Q

NOTE: Accelerating someone through motor skills we slow them down

A
31
Q

NOTE: If you change someones movement pattern within the skill they’re going to be much worse at the skill (think switching squatting form so you’re not hurting yourself will decrease the amount you’re able to squat at first)

A
32
Q

KNOW: Large amounts of improvement occur during early practie; smaller amounts of improvement occur during lateral practice

Cognitive –> Assocaitive –> autonmous

We need large amounts of change to get us from cognititve to assicative nad less from assocative to autonmous so it will look like you accelerate really quickly at the start then slow down (think noobie gains)

Early stages = big changes

A
33
Q

What are freezing of the degrees of freedom?

A

Hd to toe, if im doing an activity that makes me use multiple parts of my body - it is our nature to protect ourself - so you freeze up most aspects of your body when you’re attempting to learn the new movement parttern (more rigid or locking down) - this causes balance issues etc

34
Q

KNOW: we can be fighting prelearned motor pattern if were trying to change a skill

A
35
Q

KNOW: As the person becomes more coordianted w/ the skill they use their visual attention differently. it becomes more broad and produces more information (less specific)

A
36
Q

KNOW: Whatever sensory environment the learning occured - the learning is going to be specific to that places

A
37
Q

What is the only charcterstic that does not change across the stages of learning?

A

Sensory feedback (if you’re only ever working w/ pt in your clinic they are always going to have the same sensory environment and does not transfer over well to the real world –> they won’t depenstrate the same level of learning when they go to a different environment and ask them to do the same task –> switch up the environment!!!)

38
Q

What is the one thing that takes you from the cognititve phase to the expert phase?

A

Practice

39
Q

What are the 3 important aspects of practice?

A

1) Intense practice

2) Deliberate praoctice to improve specific aspects of perforamnce

3) Sucessive refinement (need to refine what you’re doing) - can’t just do something over and over again and not refine what you’re doing - need to be deliberate about what you’re doing

40
Q

are experties domain specifc?

A

Yes, if they are expert in one field they won’t be an expert in another one

41
Q

Do novice or experts use more visual attention

A

Experts - but they get far more from that visual attention than that novice does (they get more meaning from it)

they get a lot more meaning a lot faster from that visual attention - can look at environment and get taht information a lot faster than a novice (recognize patterns in the environment faster)

42
Q

KNOW: Trasnfer of learning: previous ability to do amotor skill affect the ability to learn a new one

A
43
Q

IS transfer of learning good or bad

A

Can be both

44
Q

What is a posititve transfer?

A

Previous experience makes learning a new motor skill easier

45
Q

What is a negative transfer?

A

Previsous experience makes learning a new motor skill harder

“I can’t learn this because I learned this”

46
Q

KNOW: Negative transfer is when two skills are two similar so I can’t unlearn one so I can learn the other

A
47
Q

Are the effects of negative transfer long lasting?

A

No! you can typically unlearn something pretty easy

48
Q

What phase of motor learning do positive and negative transfers take place?

A

Cognitive phase

49
Q

For the electric slide dance, give how we would learn it in the cognittive, associative, and aoutonmous stage

A

Cognittive: Learning direction and timing of movement - lots of repetition (proably mass practice since more novel - do it over and over again without much break between). Do things close to the body because you tend to learn them faster. Slow everything down. Part practice (high complexity low organization).

NOTE: you would get the most benefit from mental practice as you’re transfering from cognitive to assocaitve phase

**Associative: **Change the environment (increase adaptiability), move to whole practice

NOTE: You can also use mental practice here “you’re visulizing doing this as perfectly as possible”

Autonmous: in this phase they would just go - don’t really need practice here

50
Q

Would mental practice help more with electric slide or roller skating?

A

Electric slide
