Closed loop control is a theory of motor control that involves an executive, comparator, and effector components. The steps in the closed loop schematic diagram starts off with the input (stimuli) which then goes through info processing. the info processing is the executive stage and within this stage there are three different process that occur. The first process is the Stimulus identification, which identifies what it is. Then after is the response selection and then follows the response programming. After comes the output which leads into the effectors, or muscle glands. Also coming from the output is the desired state which leads to the cerebellum. From the muscle glands there are two types of feedbacks. The two types of feedbacks are interceptive and exteroceptive. These both lead up to the cerebellum, also known as the comparator, the third component. The comparator receives info about the desired state and actual state and compares. After comparing it goes through motor error and then updates the stimulus identification.

In lab, we dribbled the ball and focused on bouncing it in a limited area. Trying to dribble in a targeted area we had to make sure that our body positioning was aligned correctly to be successful. The closed loop control is a good strategy for slow, deliberate movement, such as continuos skills. Also, attention demanding for the information processing stage. Trying to focus and dribble in this small area, the closed loop control is appropriate. Using vision to see where the ball needs to be dribbled, the brain remembers where to bounce the ball. Not only is visual feedback helpful, but the sense of touch. The way you felt the ball leave your hand and the force you used to keep the ball in control all matters.

Visual feedback is an exteroceptive. This feedback does play a significant role because watching where the ball rebounds off the floor makes it that much easier to reset the correct placement. Allowing...
