Question 1

Which of the following best describes Bernstein's 'degrees of freedom' problem in motor control?

Accepted Answer

The challenge of coordinating multiple muscles and joints to produce smooth, effective movement due to the many independent components that can be controlled.

Question 2

According to schema theory, what is the primary advantage of variable practice over constant practice?

Accepted Answer

Variable practice leads to the development of more flexible and generalizable motor schemas, improving transfer to novel tasks.

Question 3

Which of the following is an example of 'chunking' in hierarchical learning?

Accepted Answer

Memorizing the sequence 'FBI, CIA, KGB, UPS' instead of 'F, B, I, C, I, A, K, G, B, U, P, S'.

Question 4

Fitts' three-stage theory of learning describes the progression from:

Accepted Answer

Cognitive stage, to associative stage, to autonomous stage.

Question 5

Which type of feedback is defined as information provided as a natural consequence of making an action?

Accepted Answer

Inherent (intrinsic) feedback

Question 6

A coach provides a gymnast with information about the quality of their movement pattern during a routine. This is an example of:

Accepted Answer

Knowledge of performance (KP)

Question 7

Why can too much augmented feedback during practice be detrimental to long-term motor learning?

Accepted Answer

It can create dependency on external feedback, preventing the learner from developing intrinsic feedback mechanisms.

Question 8

Which practice schedule is most likely to result in stronger memory representations and better transfer to new tasks?

Accepted Answer

Random practice

Question 9

In the context of sensorimotor learning, what does the 'consolidation' stage refer to?

Accepted Answer

A period after practice where gains in performance become effective, often involving continued changes in brain activity.

Question 10

Which of the following best illustrates the concept of muscle synergies in solving the degrees of freedom problem?

Accepted Answer

Co-activation of groups of muscles by a single neural command to produce coordinated movement.

Question 11

A physical therapist wants to maximize a patient's ability to transfer a learned walking pattern to different environments. According to the lecture, which practice condition should the therapist use?

Accepted Answer

Practice conditions that closely resemble the performance environment.

Question 12

Which of the following is a prediction of schema theory regarding practice?

Accepted Answer

Variable practice leads to better transfer to new but related tasks.

Question 13

In the context of motor learning, what does the following equation represent?

$$	ext{Movement\ Error} = \frac{	ext{Sum of Errors Across Trials}}{	ext{Number of Trials}}$$

Accepted Answer

A measure of average motor performance across practice trials.

Question 14

Which of the following best describes the associative stage in Fitts' three-stage theory of learning?

Accepted Answer

A transition from conscious to automatic control of the skill.

Question 15

A learner practices a tennis serve by alternating between different types of serves in a random order. According to the lecture, this practice schedule is likely to:

Accepted Answer

Enhance memory representation and improve transfer to novel serves.

Question 16

Which of the following is an example of augmented feedback?

Accepted Answer

A coach tells a runner their split times after each lap.

Question 17

According to the motor learning paradigm, which stage demonstrates true learning of a motor skill?

Accepted Answer

Retention

Question 18

Which of the following statements about feedback frequency is supported by the lecture?

Accepted Answer

Reducing feedback can facilitate learning retention, even if it slows acquisition.

Question 19

Which of the following best explains why random practice is more effective than blocked practice for long-term learning?

Accepted Answer

It increases contextual interference, making tasks more distinct and meaningful, resulting in stronger memory representations.

Question 20

A patient is learning to walk again after a stroke. The therapist provides feedback only when the patient's gait falls outside a predetermined acceptable range. This is an example of:

Accepted Answer

Bandwidth feedback
