Answer :
Final answer:
Therapists working with patients use case study research, naturalistic observation involves observing behavior in natural settings, and surveys gather data by questioning individuals.
Explanation:
Case study is the type of research approach where a therapist works with a patient over an extended period of time, like Sigmund Freud did with his clients to develop his theory of human personality. This method allows for an in-depth understanding of individual cases but may lack generalizability to the larger population.
Naturalistic observation, also known as observational studies, involves observing behavior in natural settings without intervention. For example, a biopsychologist watching animals in their natural habitats uses this method to collect valid and true-to-life information.
Survey is another type of research method used to gather data by questioning a sample of individuals about their thoughts, opinions, or behaviors. Surveys are often used in social sciences to understand trends and attitudes in a population.
