Book excerpt: In "Wired Child," child and adolescent psychologist Dr. Richard Freed exposes the powerful myths that underlie our kids' use of technology. These myths have encouraged the "wiring up" of a generation of youth, seducing kids to spend endless hours with digital self-amusements that damage family bonding and education, and put kids at risk of addiction. Written for parents, teachers, and others who care for children, "Wired Child" uses the science of behavior and brain function to provide a common-sense guide to build the strong families children and teens need, promote their success in school, limit their risk of tech addiction, and encourage their productive use of technology.
