Attunement forms the foundations for later emotional self-regulation. Children who are deprived of this joyful, mutually trusting social experience often face emotional difficulties and exhibit erratic behavior in their later years. They can have difficulty forming healthy attachments as adolescents and as adults they may be less able to cope with unexpected challenges, regulate emotions, make sound decisions when risk is involved, or learn to deal effectively as they enter into more and more complex social interactions.[17]
