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

Autonomous stage

Answer

Associative stage

Answer

Procedural stage

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

Temporary changes in motor behavior resulting from fatigue or motivation

Answer

Immediate adaptations to new environmental demands during task performance

Answer

Reflexive motor responses to sensory stimulation

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

Multiple skills are practiced simultaneously across different environments

Answer

Practice is distributed among several therapists or instructors

Answer

Task difficulty is distributed gradually from simple to complex

Question 4

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

Accepted Answer

Basal ganglia

Answer

Cerebellum

Answer

Hippocampus

Answer

Prefrontal cortex

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

Intrinsic sensory feedback received during movement execution

Answer

Information about the kinematic pattern or quality of the movement

Answer

Visual feedback provided continuously during task performance

Question 6

According to the systems model of motor control proposed by Shumway-Cook and Woollacott, movement emerges from:

Accepted Answer

The dynamic interaction of the task, the individual, and the environment

Answer

Pre-programmed motor commands generated solely by the motor cortex

Answer

Hierarchical commands descending from higher to lower motor centers

Answer

Reflexive responses to sensory stimuli mediated by spinal circuits

Question 7

Which practice schedule has been shown to produce the greatest long-term retention and transfer of multiple motor skills, despite producing slower initial acquisition?

Accepted Answer

Random practice

Answer

Blocked practice

Answer

Serial practice

Answer

Massed practice
