While the genesis of self-awareness at approximately 18 months old is a dramatic landmark in human development, there is at this stage no explicit awareness on the toddler's part of his/her truly standing apart from others. Only much later does a distinct sense of self shift into focus, and here Sartre provides us with a compelling theory of a first reflective experience of self-awareness. He explains this phenomenon by emphasizing a violent shift in ontological status, one in which the pre-adolescent (...) child is precipitated from functional unity with a primary caregiver to an individuated state involving self-awareness as privative, i.e. where the child becomes aware of existing only in the form of not-being-the-adult. For Sartre this new experience of self is not therefore positive but rather formal or empty; there has in fact been a psychic transition, from being to nothingness. In addition, Sartre also states that all children first explicitly experience themselves in this fashion. These claims find support in the work of developmental psychologist Margaret Mahler. In fact, in spite of the vast developmental discrepancies between toddler and pre-adolescent child, given the appropriate environmental triggers privative subjectivity will be shown to involve a regression to the much earlier rapprochement stage of development described by Mahler.
