Naturalistic observation is a method of observation, commonly used by psychologists and social/behavioral scientists, that involves observing subjects in their natural habitats. Researchers take great care in avoiding making interferences with the behaviour they are observing by using unobtrusive methods. When using Naturalistic Observation, the researcher observes the studied behavior in its natural setting without attempting to influence or control it.
