What are the 6 observational techniques?
Naturalistic observation
Controlled observation
Covert observation
Overt observation
Participant observation
Non-participant observation
What is naturalistic observation?
Take place in a setting where the target behaviour would usually occur.
What is controlled observation?
There is some control over variables (e.g. extraneous variables).
What is covert observation?
Participants are unaware that they are the focus of the study. Behaviour is observed in secret.
What is overt observation?
Participants know they are being observed and had given their informed consent beforehand.
What is participant observation?
When the observer becomes part of the group they are studying.
What is non-participant observation?
When researcher remains separate from those they are studying.
What is a strength of naturalistic observation?
It has high external validity because it can be generalised to everyday life as behaviour is studied in an environment where it would normally occur
What is a limitation of naturalistic observation?
Lack of control over extraneous variables
What is a limitation of controlled observation?
Produce findings that may be less generalised to real life.
What is a strength of controlled observation?
Extraneous variables are controlled so replication of research method is easier.
What is a strength of covert observation?
Removes participant reactivity (e.g. demand characteristics) so behaviour is natural => increased internal validity
What is a limitation of covert observations?
Ethics may be questioned. Participants’ privacy was violated and there is no informed consent.
What is a strength of participant observation?
They would gain increased insight about lives of the participants being studied => increased validity
What is a limitation of participant observation?
Researcher may identify strongly with the participants and lose objectivity.
