The fourth edition of Developmental-Behavioral Pediatrics-the pioneering, original text- emphasizes children's assets and liabilities, not just categorical labels. It includes fresh perspectives from new editors-Drs. William Coleman, Ellen Elias, and Heidi Feldman, as well as further contributions from two of the original editors, William B. Carey, M.D, and Allen C. Crocker, M.D. This comprehensive resource offers information and guidance on normal development and behavior: genetic influences, the effect of general physical illness and psychosocial and biologic factors on development and behavior. It is also sufficiently scholarly and scientific to serve as a definitive reference for researchers, teachers, and consultants. With a more user-friendly design and online access through Expert Consult functionality, this resource offers easy access comprehensive guidance.
