research methods: observational techniques Flashcards
What are the 6 types of observation?
- naturalistic
- controlled
- overt
- covert
- participant
- non-participant
Why do psychologists use observations?
- an alternative experimental method in addition to experiments and self-report techniques
- provide the researcher with a way of seeing what people do without having to ask them
- allow researchers to study observable behaviour in a controlled or natural environment
What is a naturalistic observation?
Watching and recording behaviour in the setting within which it would naturally occur
- all aspects of the environment are free to change
What are the advantages of a naturalistic observation?
- high external validity
- findings can be generalised to everyday life as the behaviour is studied in the environment it would normally take place in
What are the disadvantages of a naturalistic observation?
- lack of control over the situation makes replication of the investigation difficult
- there may be uncontrolled extraneous variables that make it more difficult to identify any pattern of behaviour
What is a controlled observation?
Watching and recording behaviour within a structured and controlled environment
- data can still be recorded discreetly
- you can manipulate variables to observe effects
What are the advantages of a controlled observation?
- extraneous variables are less of a problem as the setting is controlled
- more easily replicated due to control and standardisation over specific factors
What is a disadvantage of a controlled observation?
- the artificiality of the observational environment might result in unnatural behaviour, not like behaviour shown in real-world situations
- Findings cannot be as easily generalised to real life
What is an covert observation?
Participants’ behaviour is watched and recorded without their knowledge or consent
- behaviour being observed must be public for the research to be ethical
What is an advantage of covert observations?
- Participants do not know they are being studied which removes the problem of participant reactivity
- far more likely to show naturalistic behaviour free from demand characteristics or social desirability bias
What is a disadvantage of covert observations?
Ethical issues - informed consent
- people might not want to be studied and haven’t given permission
What is an overt observation?
Participants’ behaviour is watched and recorded with their knowledge or consent
What is an advantage of an overt observation?
More ethical as informed consent has been given
What is a disadvantage of an overt observation?
Since participants know they are being observed, they might change their behaviour
- demand characteristics and social desirability bias are more likely to be demonstrated
What is a participant observation?
The researcher becomes a member of the group whose behaviour they are watching and recording
