Psychologists use naturalistic observation to study animal behavior, while archival research and case studies are also research approaches but not as common for this purpose.
Naturalistic observation is the type of research method often used by psychologists to learn about animal behavior. This method involves observing and recording behavior in everyday settings, such as watching animals in their natural habitats. For example, a biopsychologist studying animal behavior in their natural environment is using naturalistic observation to gather data.
Archival research is another type of research method where existing records are used to answer research questions but is not typically used to study animal behavior.
A case study is another research approach where in-depth investigations are conducted on a single individual or small group to gain insights into behavior, but it is not as commonly used as naturalistic observation in studying animal behavior.
