observation Flashcards
What is an observation?
Observe behavior of a sample and look for patterns
How can observations be used?
It is used as a part of another research method such as a lab study
What is participant reactivity?
The type of reactivity in which individuals modify. An aspect of their behavior in response to their awareness of being observed (Hawthorne)
what’s another word for participant reactivity?
Hawthorne effect
What is inter-rater reliability?
There should be at least two observers because single observer may miss important details.
Correlation of the result should be as close to 1 as possible (0.8 to be reliable)
What are naturalistic observations?
Observation of behavior in its natural setting
What are the strengths of naturalistic observations ?
High level of ecological validity
Less likely to be affected by demand characteristics as they are no aware they are being studied
What are the limitations of naturalistic observations?
Little control of ev
Replication I often not possible
What are controlled observations?
Observation taking place in a controlled setting, usually behind a one way mirror
What are the strengths of controlled observations?
There is less risk of ev affecting the behaviors as it is in a controlled environment
What are the limitations of controlled observations?
The setting is artificial – lack ecological validity
What are structured observations?
The researcher creates a behavioral checklist before the observation.
Behavior can be sampled using time or event sampling
What is a behavioural checklist?
record the frequency of those behaviors
Criteria for a behavioural check list?
Observable
Have no need for inferences to be made
Cover all possible components behaviours
Must be mutually exclusive
What is a pilot study?
Small scale study carried out before the actual research. So researchers can adjust the study if there’s any problems
