Two Types of Feedback: Knowledge of Results and Knowledge of Performance
Starting a series on feedback, Nicole explains the difference between binary knowledge of results (KR) feedback and the specific knowledge of performance (KP) feedback used in the early stages of motor learning.

Nicole here, coming in from the NYU Motor Speech Lab with a Monday tidbit on a Tuesday. I'll try to make them on Mondays going forward.
One of the things I want to talk about over the next couple of weeks is feedback, and why the feedback that we as therapists give our clients is so incredibly critical to their motor learning and motor performance.
We'll start with the basics. There are broadly two types of feedback: knowledge of results, or KR feedback, and knowledge of performance, or KP feedback.
Knowledge of results is just how it sounds: "Great job." Did they get it? It's binary, yay or nay, or "Try again."
Knowledge of performance feedback is the feedback we focus on in the early stages of motor learning, when you are introducing the target word, when you're really practicing and figuring out the motor movement for the gesture. This type of feedback is very specific. Say the target word is "bye": "Did you feel the way your lips came together, and then your mouth opened up really big, and then came down tight again, almost into a smile? Bye." That would be knowledge of performance feedback, and that will set your client up for success.
