There are two different types of feedback, knowledge of results (KR) and knowledge of performance (KP). Knowledge of results refers to "extrinsic information that tells learners something about the success of their actions with respect to the intended environmental goal" (286). An example of this would be providing a person with feedback on their performance after the action has taken place, such as after kicking a soccer ball explaining what the person did wrong or could do better. Knowledge of performance is information given to a person that provides information about the quality of the movement. An example of this would be whether a dance move was smooth and what the person could do to improve it.
During the lab performed in class on November eighth we used a pencil, ruler, blindfold, calculator, masking tape, and test sheet. We were paired with a partner and taped the test sheet to the desk in front of us. One partner performeda test with 100% KR and the other with requested KR. Each person was blindfolded and asked to mark from one line to the other with a pencil, teh 100% KR person was given feedback after every try, while the other received feedback only when requested. During our lab KR was requested fourteen times out of thirty trials. Caitlin performed the 100% KR part, and I did the requested KR section. During the constant feedback trial, the retention test showed that she had a 1mm average, while the requested KR had a 0.33mm average. In our test the requested KR showed to be more effective.
Our results matched the results given in the text and lab handout. These stated that requested feedback was proven more effective, because it allows for the person to process what actions they are making. This type of feedback could work the best because the information given could reinforce correct behavior, as stated in the lab handout. Other factors that may have influenced this could be that one person has better hand eye coordination, one person could have practiced while the constant feedback person was performing, or there could have been an error in measuring. Overall, the lab was very fun to perform and provided us with valuable information that gave us a clear understanding of "knowledge of results".
