Discussion: Motor Skill Acquisition
1. How does vision dominate the sensory feedback system and how might it influence proprioception? What potential problems created by visual dominance might a person encounter during motor skill acquisition? Why are these significant?
2. Some researchers assert that rhythmic or stereotypical movement patterns, such as locomotion, could be controlled without any involvement of the cerebral cortex. Hypothetically, these rhythmic movements could be controlled by neural circuits known as central pattern generators (CPG). Although CPGs are often cited in research examining hierarchical control of human movements, it is unclear how CPGs can explain the plasticity and responsiveness necessary in real human movement. Are central pattern generators fact or fiction? Why?
