The author notes that children with learning and behavior disorders evoke different kinds of responses from their parents, teachers, siblings, and classmates than other children do. These responses affect how the children develop socially, cognitively, and emotionally. The author describes the essential features of several types of disorders: dyslexia, attention-deficit hyperactivity disorder, executive function disorders, spatial cognition difficulties, nonverbal learning disabilities, and Asperger's disorder. He then describes the complex interaction between a disability and a child's environment, and how that shapes the child's developing sense of who he or she is and what he or she might become.
