What is observer-produced information?

What is observer-produced information? Describe its role in somersaulting and why there is a difference between novices and experts when they close their eyes.

Observer-produced information is often referred to as self-produced information, which is “[w]hen a person makes a movement, that movement creates information, and this information is, in turn, used to guide further movement (Goldstein, 2014, p. 155). Self-produced information is information gathered from practicing a certain move such as a somersault and identifying occurrences that need to happen and when to properly execute a move such as a somersault. It is interesting to find that novices can often execute moves such as a somersault better than experts as they have not yet developed the coordination cues that aid them in executing the same move time and time again (normally with their eyes open). This makes me think about the old saying of “beginners luck”, and I believe it is instances like this that make that statement true. It think that with practice and time that an expert could also master the move using different variables, but it may take them longer to learn a different way to do a move like a somersault than someone who has not yet established a method.
