Compare motor programs from both open and closed loop perspectives.
• Open loops – performance of a skill without recourse to feedback
• hitting (or attempting to hit) a 100mph fastball or a 140mph
tennis serve
• (no alteration of movement possible – since the stimuli is too
fast for feedback/adjustments to occur)
• Closed loops – involves the process of feedback
• not all movements take place so quickly – many can be altered
during their execution
1)
Control is internal (proprioceptors
detect and correct errors)
2)
Perceptual trace- memory for the
feel of successful past experience/movements
• (slower pitch reaction, slower serves, deflected or redirected
balls)
Exercise Difference Between Positive and NegativeAn Exercise in the Difference Between Positive and Negative Self-Talk. I want to take a moment to show you the difference between negative and positive self-talk. This won’t take long. Do not drive or operate any form of machinery while doing this. Do this if you are able to focus and are open to getting really into it. In just a moment, you are going to close your eyes and as I talk, you are going to imagine that you are thinking the words that I’m saying.
