CNS Motor Control and Motor Learning 2

Question 1

Contextual interference in motor learning refers to:

Accepted Answer

The interference created by practicing multiple skills in a random order, which enhances long-term learning

Answer

Contextual interference is the functional interference created when multiple skills are practiced in random order; although it disrupts initial acquisition, it enhances long-term retention and transfer.

Question 2

Bernstein's 'degrees of freedom problem' in motor control refers to:

Accepted Answer

The challenge the nervous system faces in controlling the many independent joints and muscles available for movement

Answer

Bernstein's degrees of freedom problem refers to the challenge of selecting and coordinating the enormous number of independent joints and muscles (degrees of freedom) available in the motor system.

Question 3

Which augmented feedback schedule BEST promotes long-term motor learning by fostering the development of internal error detection?

Accepted Answer

Faded feedback that decreases in frequency as practice progresses

Answer

Faded feedback decreases in frequency over practice, promoting long-term learning by requiring the learner to increasingly rely on internal error detection mechanisms rather than external feedback.

Question 4

Transfer of training in motor learning is BEST defined as:

Accepted Answer

The influence of prior practice or experience on the learning or performance of a new task

Answer

Transfer of training refers to the gain or loss in proficiency on one task as a result of practice or experience on a different but related task.

Question 5

Feedforward motor control mechanisms are BEST characterized as:

Accepted Answer

Anticipatory motor commands prepared before movement begins based on predictive internal models

Answer

Feedforward control uses internal predictive models to anticipate and prepare motor commands before movement begins, enabling rapid, smooth movement without waiting for sensory feedback.
