"So big": the development of body self-awareness in toddlers.
Early development of body self-awareness was examined in 57 children at 18, 22, or 26 months of age, using tasks designed to require objective representation of one's own body. All children made at least one body representation error, with approximately 2.5 errors per task on average. Errors declined with age. Children's performance on comparison tasks that required them to reason about the relative size of objects and about objects as obstacles, without considering their own bodies, was unrelated to performance on the body awareness tasks. Thus, the ability to represent and reflect on one's own body explicitly and objectively may be a unique dimension of early development, a distinct component of objective self-awareness that emerges in this age period.
