Naturalistic observations, case studies, and correlational studies are all non-experimental research methods that do not allow the researcher to manipulate or control the variables of interest. They rely on observation and measurement of naturally occurring phenomena in the real world. Causal hypotheses are not always tested using these methods. They are also used by researchers from various fields of psychology, not just biological psychology. These methods are considered scientific, although they may have limitations in terms of establishing cause-and-effect relationships between variables.
