Research Methods : Observations Flashcards
What’s an observation?
A researcher will just observe behaviour of a sample and look for patterns
• cannot draw a cause and effect relationship
Naturalistic observations
An observation of behaviours in its natural setting, the researcher makes no attempt to influence behaviour (where its unethical to manipulate)
Naturalistic observations advantages
• high levels of ecological validity as in a natural setting
• less likely to be demand characteristics (unaware of being studied)
Naturalistic observations disadvantages
• little control over EVs
• replication is not often possible (can’t check reliability)
Controlled observations
An observation taking place in a controlled setting where researcher can’t be seen
Controlled observation ads
• less risk of extraneous variables affecting behaviour
Controlled observations disads
• less ecologically valid as setting is artificial
Structured observations
An observation where the researcher creates a behavioural checklist before the observation in order to code the behaviour (with event or time sampling)
Behavioural checklist
Target behaviour is spilt into categories which are checked off when displayed
Participant reactivity
Type of reactivity where individuals modify their win behaviour in response to their awareness of being observed (hawthorn effect/ observation effect)
Inter-rather reliabity
The reliability - two observers min compare their data at the end of an experiment and the correlation should be higher than 0.8 to be reliable
Structured obersavtions ads
• allows quantitative data to be collected (can be statistically analysed)
• allows for more than one observer to carry out the experiment (increase reliability)
Structured observations disads
• behavioural categories can be restrictive (some behaviours may be missed)
• doesnt explain why behaviour is happening
Unstructured observations
The observer notes down all the behaviours they can see in a qualitative form over a period of time (no behavioural checklist)
Unstructured observation ads
• rich qualitative data that can explain behaviour collected
• researchers not limited by prior theoretical expectations
