The word proprioception means a kind of self-perception. The word is derived from ‘proprio’ and ‘ception’. Proprio comes from Latin ‘proprius’, meaning ‘one’s own’. So proprioception means an awareness or perception of oneself. In the case of the body proprioception means the awareness of one’s own body. But we will also use it in a psychological sense to mean the awareness of one’s own thoughts and the awareness of one’s own felts.
Proprioception is to be aware of every movement. Not only physical movements of the body but also the movements of thought. Emotions are movements as well. So, there could be proprioception of emotions also.
