Interpersonal experience shapes the mind as it continues to develop throughout the lifespan... Interactions with the environment, especially relationships with other people, directly shape the development of the brain's structure and function.
Daniel J. SiegelInternal mental experience is not the product of a photographic process. Internal reality is in fact constructed by the brain as it interacts with the environment in the present, in the context of its past experiences and expectancies of the future. At the level of perceptual categorizations, we have reached a land of mental representations quite distant from the layers of the world just inches away from their place inside the skull. This is the reason why each of us experiences a unique way of minding the world. (pp. 166-167)
