Final answer:
Stature and health are physiological determinants influenced by both biological systems and one's physical environment, according to the study by Franz Boas.
Step-by-step explanation:
Factors such as stature and health are included in physiological determinants. While social and cultural factors do play a significant role in a person's development and socialization, stature and health are often considered physiological because they are directly related to the body's physical state and biological systems. Franz Boas's study on immigrants to the United States highlighted that health is influenced by numerous factors, including many that are determined by one's social and physical environment. However, in the context of social psychology, it's also important to consider situational factors, which include the immediate social and physical environment that can affect an individual's behavior.
