CNS Motor Control and Motor Learning

Question 1

According to the Fitts and Posner three-stage model, which stage of motor learning is characterized by the highest cognitive demands, frequent errors, and large performance gains?

Accepted Answer

Cognitive stage

Answer

The cognitive stage is the initial phase where learners require significant conscious attention, make frequent errors, and show the largest performance gains as they work to understand the task.

Question 2

Which of the following BEST defines motor learning?

Accepted Answer

Relatively permanent changes in the capability for skilled motor behavior resulting from practice or experience

Answer

Motor learning refers to relatively permanent changes in the capability for skilled motor behavior that result from practice or experience, distinguishing it from temporary performance fluctuations.

Question 3

Distributed practice in motor learning is defined as a schedule in which:

Accepted Answer

Rest intervals equal or exceed the actual practice time

Answer

Distributed practice involves rest intervals that are equal to or longer than the actual practice time, and is generally more effective for long-term retention than massed practice.

Question 4

Which brain structure is primarily responsible for procedural motor learning and habit formation through dopaminergic reinforcement pathways?

Accepted Answer

Basal ganglia

Answer

The basal ganglia are critical for procedural motor learning and habit formation, working through dopaminergic reward pathways to reinforce and consolidate motor programs over repeated practice.

Question 5

Knowledge of Results (KR) in motor learning is BEST described as:

Accepted Answer

Augmented feedback about the outcome or goal achievement of a movement

Answer

Knowledge of Results (KR) is a form of augmented feedback that provides information about the outcome or goal achievement relative to the intended goal, rather than about movement quality.
