HDFS 129 introduces students to developmental tasks and challenges unique to each stage of human development from the womb through infancy, early and middle childhood, adolescence, emerging adulthood, middle age and old age. Students are guided to understand the biological, emotional, cognitive, psychosocial, as well as the social, cultural and historical factors that influence growth and development across the lifespan. BBH 101 is an interdisciplinary study of health that emphasizes: (1) Conceptualization of health as being influenced by a variety of factors including biology, environment, psychology, and social influences; and (2) The concept of health as a state of physical, mental, and social well-being, and not just the absence of disease.
