"Healthy human 6-month-olds can look where a caregiver looks, then by 18 months, understand when they are sharing a moment of focus. This is joint attention, a seemingly simple but extraordinarily rich moment of first connection, courtesy of the orienting network. One of the first signs of autism is a deficiency in it; autistic children miss others’ “bids” for sharing attention and don’t initiate shared focus. Orienting is our bridge to one another. Lose the will to focus deeply, to point the compass of our lives in one another’s direction, and we become islands."
