Book excerpt: In Understanding Abnormal Child Psychology, students will learn about both normative and abnormal development throughout children’s lives. Consistent with previous editions, several themes run throughout the book: Developmental psychopathology: Children's and adolescents' behaviors are on a continuum (from very adaptive to very maladaptive), with only the very severe ends of the spectrum being conceptualized as disorders. Diversity, inclusion, and understanding: Special attention is given to issues of race/ethnicity, gender, family constellation, religious orientation, primary language, socioeconomic status, and physical differences to help students see the commonalities and differences of abnormal child behavior within a cross-cultural and international context.
