Document Summary
A set of muscle commands that are organized in advance & run off without much feedback(open loop) All or none initiated then carried out without modification. Cd defines which sounds occur and in what order, duration, and timing. Reaction time increases as the complexity of the movement increases. Rt is longer because more time is required to organize action. Longer duration skills(only true if it"s caused by the first 2) Respond as quickly as possible to a light. Lift finger, reach and grasp a ball. Lift finger, hit several targets in different directions. Rt increased with added complexity of task (150, 195, 208 ms, resp. ) Therefore, increased rt occurred due to a more complex response. Deafferentation: cutting sensory nerves so the cns does not receive sensory information. What are we capable of when deprived of feedback from the limbs. Monkey still able to climb, and chase. However, difficulties with fine motor control (eating)
