In his monumental research, although Piaget primarily relayed information about children's developmental stages of cognitive growth, Marian Marion goes on to discuss not only the developmental stages, yet focuses on how children think. In her textbook, "Guidance of Young Children", Marion conveys how teachers need to understand children and help them develop decision-making skills, resulting in them making appropriate choices and demonstrating self-regulation and pro-social behaviors. The author explains clearly the difference of a child being egocentric and selfish. As teachers understand the difference, they can more fully observe the motivations of children attempting to meet their own needs. Marion also focuses on other perceptions of young children including: (1) searching and scanning; (2) impulsivity affecting perception; (3) selecting things in which to ignore; (4) staying on task; and (5) intentional versus accidental behavior. Marion's writing has many applicable child scenarios, research on children, and well-grounded theories. The book is recommended for all early childhood majors and teachers, especially those who have been frustrated with "normal" childhood behaviors. Marion's unique style of presenting information adds a much greater dimension to previous child development information presented in teacher training institutions.
