Choose one of the following stages of life: Infancy and Toddlerhood, Early Childhood, Middle Childhood, Adolescence, Early Adulthood, Middle Adulthood, Late Adulthood, or the End of Life. Interview or observe two people in that stage. For example, if you choose Early Childhood, observe two children between the ages of 2-6 years of age or if you select Late Adulthood interview two adults who fall within that range and answer the following questions: How do they compare to each other in their Physical, Cognitive, Emotional, and Social Development? What biological or environmental influences might be affecting those differences or similarities? How might cultural influences affect those differences or similarities? Are there any other factors that might be affecting those differences or similarities?
