Questions and Answers

Which of the following best describes 'degrees of freedom' in the context of motor control?

  • The consistency in performing a motor skill across repeated attempts.
  • The brain's capacity to control numerous variables simultaneously. (correct)
  • The ability to alter a movement pattern while executing it.
  • The sequencing and timing of individual movements.

Serial order in motor skills refers to the ability to change a movement pattern once it has begun.

False (B)

Define 'motor variability' and provide a brief example that is not already mentioned in the text.

Motor variability is the ability to alter or change a movement pattern while it is being executed. Example: A tennis player adjusting their serve based on the wind.

Study Notes

  • Motor control is the brain's ability to organize and execute smooth, coordinated, and controlled movements

Fundamentals and Principles

  • Degrees of Freedom: The brain and nervous system's capacity to control many variables simultaneously
  • An example is a basketball player controls several variables when shooting a free throw like, joint angles, force, trajectory, stability, and focus
  • Serial Order: The sequencing and timing of individual movements combine into complex motor skills
  • An example is a gymnastics routine, which contains a sequence of movements, where flow and timing are critical
  • Motor Variability: The ability to alter or change a movement pattern during execution
  • An example is a badminton player adjusting footwork, arm reach, and racket angle while reaching for a shuttlecock
  • Motor Consistency: The ability to reliably perform a motor skill with similar outcomes across repeated attempts
  • An example is a volleyball player consistently serving the ball into a specific zone with high accuracy
  • Motor Modifiability: Natural fluctuations and adjustments occurring during motor skill performance
  • An example is a soccer player making subtle adjustments to foot movements while dribbling based on ball movement, terrain, and defender position
  • Motor Equivalence: Achieving the same movement outcome using different combinations of muscles or body parts
  • An example is a basketball player making a shot from various positions using differing arm and leg movements with the same result
  • Perceptual Motor Integration: Combines sensory input with motor actions for effective environmental interaction
  • An example is a fielder tracking a fly ball integrates visual information with motor commands
  • Motor Learning: Acquiring and refining motor skills through practice, leading to permanent skill improving
  • Several elements or conditions influence or affect motor learning
  • Age can influence a learner's capacity for motor learning
  • Musculoskeletal factors can impact motor learning
  • Prior experience can impact motor learning
  • Motor Learning: A lasting change in one's capability to perform a motor skill due to practice or experience
  • Motor Performance: The act of performing a motor skill
  • Motor Skill: It refers to movement that is goal-oriented and requires voluntary body and limb movements that must be learned
