The Fullerton Longitudinal Study, launched in 1979, chronicled the development of over 100 children and their families from the children's first birthday through their high school completion using a cross-informant/cross-context methodology. In this volume, the developmental course and sequelae of children's temperament from age 1.5 years through high school completion are documented. It is an important resource for developmental researchers, clinicians, educators, and students.
