What is Body Schema?
Body Schema is how we are aware of the presence of body in the space. More specifically, it was defined by Sir Henry Head as “a postural model of the body that actively organizes and modifies ‘the impressions produced by incoming sensory impulses in such a way that th e final sensation of [body] position, or of locality, rises into consciousness charged with a relation to something that has happened before”. Or it can be understood as “the collection of processes that registers the posture of ones body parts in space”
Body Schema and Proprioception
One of the fundamental properties of body schema is ‘supramodal’ – meaning it consists of various sources of sensory-motor information. And proprioception is one of them (which is interpreted as the sense of the relative position of neighboring parts of one’s body)
Body Schema and Body Image
The two are different in the sense that: a body image is a person’s perception of the aesthetics and sexual attractiveness of their own body while body schema conssits of sensory-motor capacities that control movement and posture. Or “body image differs from body schema as perception differs from movement”.
