Descriptive research methods: (description, advantages & disadvantages)
Naturalistic observation: researcher observes & records behaviour in its natural
setting. Participants may or may not know they are being observed.
Good source of descriptive information. Can provide basis for hypotheses to be
tested later. Behaviour studied in everyday setting is more natural.
Researchers’ expectations can distort observation (observer bias). Presence of
researcher may influence behaviour of participants. Little or no control over conditions.
Laboratory observation: observation under more controlled conditions where
sophisticated equipment can be used to measure responses.
More control than naturalistic observation.
Possible observer bias. Behaviour of participants may be less natural than in
naturalistic observation.
Case Study: in-depth study of one or a few participants using observation, interviews
or psychological testing.
Source of information for rare or unusual conditions or events. Can provide
basis for hypothesis to be tested later.
May not be representative of condition or event. time-consuming . subject to
misinterpretation by researcher.
