Attention directed to human bodies, including both one’s own and that of another person. This awareness can concern either the features/appearance of the body or the dynamics of human body movement and posture. Sometimes body awareness is restricted to proprioception. Based on proprioception (and touch) some (e.g., Philippe Rochat) claim that human newborns already demonstrate something akin to body awareness (and thus self-awreness). It is also evident from various studies that toward the end of the second year of life that infants possess a reflective seff-awareness (i.e., they regard themselves as independent entities).
