Answer:
Naturalistic Observation method is the correct answer.
Step-by-step explanation:
Psychologists use various observation methods for carrying out research in psychology. The three major observation methods are Controlled , Naturalistic and participant. Naturalistic observations are used by social scientists and psychologists. In this technique the behaviour of participants in natural surrounding is observed, and whatever is seen is recorded. The observations are cheap and require few resources. It is like studying the animals in their natural habitat. This method is less reliable because variables cannot be controlled and the study cannot be repeated in exact same way.
