6. Joint receptors do not...

  • Have different kinds of sensory receptors
  • Fire only at extreme angles to signal the body is not in useful position
  • Give us information about joint angles

7. What is not a characteristic of open loop?

  • Pre programmed
  • Execution is dependant on feedback
  • There is no feedback

8. What is perception action coupling?

  • Group of muscles spanning several joints that act as a single unit
  • Gathering of information about environment
  • Interaction between perceptual and movement variables that results in specific movement dynamics
  • Mechanical receptors that stretch and compress

9. What is not a limitation of reflex theory?

  • It has a storage problem
  • Doesn't explain absence of sensory stimuli
  • Doesn't address Sheridan's Model - not changed by environment
  • Doesn't explain fast sequential actions
  • One stimulus can result in various responses
  • Doesn't explain novel movements

10. What is a motor program?

  • Set of muscle commands that are structured before a movement sequence begins
  • A store of families of movements
  • A sensory stimuli
  • A degree of freedom

11. What is the fundamental unit of motor control according to reflex theory?

  • Feedback
  • Open/closed loops
  • Reflexes
  • Degrees of freedom

12. What is it when muscles and tendons are filled with mechanical receptors that stretch and compress to tell us about body position?

  • Auditory receptors
  • Proprioception
  • Visual receptors

13. What is the DoF problem?

  • Having a lack of biokinetic links
  • How do we move?
  • How are multiple DOF controlled without overloading system?
  • How does brain communicate with muscles?

14. What is perception?

  • Acts as a brake against excessive contractions
  • Process of obtaining information from sensory stimulation and making it available for action
  • Self organising intrinsic structural patterns

15. What is not a family of movement example?

  • Upper limb function
  • Finger movements
  • Self help skills
  • Locomotion skills

16. What is not a characteristic of closed loop?

  • Initial command
  • Pre programmed
  • There is feedback
  • Execution and completion is dependant on feedback

17. The vestibular system does not...

  • Have direct relationship between eye movement and motion sickness
  • Stabilise visual image
  • Detect only angular accelerations of head
  • Monitors posture and balance

18. Motor control is the interaction between what factors?

  • Individual and environment
  • Individual and task
  • Task, environment, individual
  • Task and environment

19. What is not a feature of a controlled movement?

  • Uses feedback
  • Slower
  • No feedback
  • Allows for correction

20. Who came up with the 4 aspects of motor control?

  • Keele
  • Schmidt
  • Sheridan
  • Adams
