Kinaesthetics (or kinesthetics, in American English) is the study of body motion, and of the perception (both conscious and unconscious) of one's own body motions. Kinesthesis is the learning of movements that an individual commonly performs. The individual must repeat the motions that they are trying to learn and perfect many times for this to happen.
