Answer:
psychologist
Step-by-step explanation:
The title Daisy Miller: A Study is surprisingly academic and matter-of-fact, considering that the book is a novel. However, the title serves a particular purpose for the author. Through this title, James wants to imitate the way scholarly articles are written. He calls his book a "study" in order to compare it to psychological treatises in which the psychologist delves deeply into the characters' actions and motivations in order to reach a scientific conclusion.
