Q

Give an example of performance fluctuating in accordance with variables that do not affect learning.

A

“Despite having studied for a test, temporary circumstances such as a headache or illness may lead to poorer performance on a test than the effort put into studying would predict.” or “A world-class athlete may have an off day that does not represent his or her usual standards, nor reflect his or her overall mastery of the skills involved.”

Q

If we can infer that learning has occurred through persistent improvement in a capacity to perform a skill, what can be said about performance?

A

This means that improvement in performance over time is relatively permanent. While small reductions in improvement may occur occasionally, the average performance over time improves as a general lasting trend.

Q

If we can infer that learning has occurred by increased consistency of performance, what can be said about error? Example?

A

The type and magnitude of errors become less variable. “For example a novice golfer may make seemingly random errors with no pattern, but with increased experience, may begin to show a specific patter of error, such as primarily slicing the ball rather than hitting it randomly over the course.”

Q

If we can infer that learning has occurred by adaptability, what can be said about other contexts? Example?

A

Adaptability means that a person can apply a learned skill across many contexts. “For example learning to play the guitar may make learning to play the bass guitar easier based on prior knowledge of a similar instrument.” or “If a person has truly learned to walk with crutches in a hospital environment, he or she should be able to apply the same rules when learning to walk with crutches on uneven terrain outdoors.”

A
  1. Kinematics (movement) 2. Kinetics (force)
24
Q

What are 4 examples of Biomechanical Measure variable Kinematics?

A
  1. Displacement - change in spatial position of an object of body part 2. Velocity - speed of a body segment 3. Acceleration - change in velocity of a body segment 4. angle and position of a limb or joint
25
Q

What are 2 examples of Biomechanical Measure variable Kinetics

A

-relate forces exerted on the body or by the body to the environment 1. Joint Torque (force*distance) 2. Ground reaction forces

26
Q

What is an example of using the biomechanical measure variable kinetics with ACL construction?

A

you may need to measure the joint torques produced at the knee during a specific activity to determine if that activity places excessive mechanical stress on the ligament repair that may cause damage to the healing tissue.

27
Q

What are other types of Performance Production Measures? (2)

A

Those that give insight to the activity of specific muscles or areas of the brain. 1. Electromyography (EMG) 2. Brain Activity

28
Q

What type of information does Electromyography (EMG) provide?

A
  1. Timing of onset of muscle activation for a given movement pattern 2. Muscle timing coordination with each other 3. reflect the relative amount that specific muscles are activated during a movement.
29
Q

What might Electromyography (EMG) show for patients with and without low back pain?

A

in individuals with low back pain, muscles may be recruited in a different pattern from individuals with no pain.

30
Q

What are the 4 different ways Brain Activity can be measured?

A
  1. fMRI 2. EEG 3. Positron emission tomography (PET) 4. rCBF
31
Q

What purpose does measuring Brain Activity serve?

A

provide insight into areas of the brain that are involved in performance of various tasks and how these change after injury or disease. Each may be utilized to measure abnormal function and indicate the magnitude or nature of improvement in response to therapeutic interventions.

32
Q

What is Error Measurement used for? (2)

A

Nearly all skilled task performance requires some level of task accuracy. 1. Evaluation of patient performance relative to the goals of task mastery is crucial to document progress toward and achievement of goals in the medical record. 2. Can reveal patterns of change in performance that a therapist can use to customize a given intervention program.

33
Q

How can error measurement help in revealing patterns of change in performance?

A

A patient might show a pattern where the magnitude of errors is not improving, but the type of error is becoming more consistent, such that you can target the reasons that particular error is occurring.

34
Q

What are the three ways you can quantify error of skilled performance?

A
  1. Absolute Error (AE) 2. Constant Error (CE) 3. Variable Error (VE)
35
Q

What is Absolute Error (AE)? How is it calculated?

A

measure of the magnitude of an error, regardless of the direction. -Criterion Score - Actual Score = Xn AE = |X1| + |X2| + |X3| + … / # trials

36
Q

Using dart board example for AE: -What is the criterion? -What is measured value? -AE = ? (person threw 3 darts which landed 5 cm, 10cm, and 15 cm away from the bulls-eye)

A

Criterion = goal, bulls-eye Measured Value = actual location where dart hit from the board (distance from bulls eye) AE = (5+10+15)/3 = 10cm

37
Q

What is Constant Error (CE)? How is it calculated?

A

average error over a given number of trails but now takes both magnitude and direction into account. Provides a measure or response bias -Mean CE

38
Q

Use patient using dynamometer to produce 40lbs example for (CE). Trial 1=45# 2=40# 3=35# 4=35# 5=30#

A

45 - 40 = 5 40 - 40 = 0 35 - 40 = -5 35 - 40 = -5 40 - 40 = -10 Mean CE = (-15)/5 = -3

39
Q

What is Variable Error (VE)? How is it calculated?

A

represents the consistency of errors made. The standard deviation of the total error around one’s own average performance. Does the person make the same type and magnitude of error with each trial, as opposed to very different errors each time.

40
Q

Use dart board example for VE. 1. Low Variable Error 2. High Variable Error

A
  1. the darts may all be far from the bulls-eye, but could be clustered together, indivating that the person makes the same throwing error each time. 2. the darts were scattered in seemingly random location on the board
41
Q

For the Taget Exp. 1 determine the whether the absolute, constant, and variable error measurements would be Large or Small.

A

AE: Large (far from target)

CE: Large (leftward bias)

VE: Large (spread out)

42
Q

For the Taget Exp. 2 determine the whether the absolute, constant, and variable error measurements would be large or small.

A

AE: Large (the dars are very far from the target)

CE: Small (don’t show any directional bias)

VE: Large (darts are very spread out)

43
Q

For the Taget Exp. 3 determine the whether the absolute, constant, and variable error measurements would be large or small.

A

AE: Large (the darts are very far from the target)

CE: Large (leftward bias)

VE: Small (darts are clustered)

44
Q

For the Taget Exp. 4 determine the whether the absolute, constant, and variable error measurements would be large or small.

A

AE: Small (darts are all on bulls-eye)

CE: Small (show no left or right bias)

VE: Small (close together)

45
Q

What are the 2 conditions that must be satisfied with tests before we can be sure that learning has occured?

A
  1. Retention of a skill
  2. Transfer of learning
46
Q

What does retention of a skill mean?

A

That improved performance last over time, even if the skill is not practiced in that inverval.

47
Q

What does transfer of learning mean?

A

that a skill learned in one set of conditions may be applied to a skill under different conditions.

48
Q
  1. What does a test of retention measure?
  2. How is it documented?
  3. What does retention reflect?
A
  1. the persistence or relative permanence of performance improvement.
  2. must assess performance of the same skill under the same conditions over time. skill is retested after a period of no practice with no feedback.
  3. Reflects the strength of motor memory representation created during the learning process.
49
Q
  1. What does a test of transfer measure?
  2. what are the different conditions
  3. What does retention reflect?
A
  1. Measures the adaptability of a skill under different conditions
  2. Novel Context (physical envrionment or feedback changes) and Novel skill variation (fast vs slow, different object manipulation)
  3. Gives information about the extent to which a learner may perform in different situations. Reflects the flexibility of the motor memory. Important when skill learned must be performed across a variety of conditions.
