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
Unstructured observations disads
• the observer may lose focus on what they’re researching due to eye catching behaviour
• more** subjective** and less comparable across researchers
Overt observation
Ps are aware their behaviour is being studied - observer is obvious
Overt observation ads
• ethical guidelines fulfilled
Overt observation disads
• demand characteristics
• participant reactivity
Covert observation
Ps are unaware their behaviour is being studied - observer is hidden
Covert observation ads
• behaviour is more natural
Covert observation disads
• may break ethical guidelines (cause Ps psychological harm)
Participant observation
The observer becomes/ is involved in the P group and is not known to be an observer by Ps
Participant observations ads
• deeper understanding of behaviour
Participant observations disads
• presence of researcher may influence behaviour
• researcher may lose objectivity as they’re part of the group
Non-participant observations
The observer is separate from the P group that’s being observed
Non-participant observations ads
• observations more objective as they’re not influenced by the group
Non-participant observations disads
• harder to understand reasons behind behaviour
Behavioural checklist
Target behaviour is split into categories which are checked off when displayed
- some behaviours are aider to categories then others
Behavioural categories
The sub sectors a certain behaviour is split into
must…
• be observable
• no need for inferences
• cover all possible components
• be mutually exclusive/ not overlap
Pilot study
Small scale study carried out before the actual research. It allows researchers to practice with behavioural checklists + observation schedules
Event sampling
Counting each time a particular behaviour is observed
Event sampling ads
• useful when target behaviour occurs frequently
• gets all details (time sampling might miss)
Event sampling disads
• if situation is busy, target behaviour could be missed
Time sampling
Recording behaviour at determined time intervals
Time sampling ads
• observer has time to record what they’ve seen
Time sampling disads
• some behaviours will be missed between the intervals, meaning results may not be representative
