William I. Thomas wrote from which perspective when observing that people respond not only to the objective features of a person or situation, but also to the meaning that person or situation has for them?

Answer: Interactionist perspective

Explanation:

interactionism is a theoretical perspective that derives social processes (such as, conflict, identity formation) from human interaction. It is the study of how individuals shape society and are shaped by society through meaning that arises in interactions. For example, there is no necessary relationship between a red truck with sirens and a fire.
