Observations Flashcards
What is an observation
A non experimental teqnique where the researcher watches and records the natural behaviour of the participants without manipulting the IV
How can observations be used
Used in psychological research, method or tequnique and usually part of a field or lab experiment where they take observations
What is participant reactivity
When the researcher joins the group being observed and takes part in their activities.
What is participant reactivity not
Demand characteristics
What is inter-rater reliability
2 or more observers conduct the same experiment and compare results
What is good about inter-rater reliability
Single observers might miss important details or only notice events that confirm their hypothesis
What are naturalistic observations
Observation of behaviour in its naturalistic setting. Researcher makes no attempt to influence the observed behaviour
When is a naturalistic observation often done
When its unethical to conduct a lab expperiment
Limitations to a naturalistic observation
- little control over the EV
-replication is often not possible
Controlled observations
Taking place in a controlled setting usually behind a one way mirror so the researcher cannot be seen
Strengths to controlled observations
Less risk of extraneous variables affecting the behaviour as its a controlled enviroment
Limitations to controlled observations
Qualitative data
Structured observations
When the researcher creates a behavioural checklist before the observation in order to code the behaviour in order of time sampling and event sampling
What is a behavioural checklist
Used to record the frequency of those behaviours (qualitative data)
Criteria for a behavioural checklist
-be observable
-have no need for inferances to be made
-cover all possible components of behaviours
- be mutually exclusive
Pilot study
A small scale study carried out before the actual research. It allows the researcher to practice using behavioural structures
event sampling
Counting each time a particular behaviour is observed
Strengths of event sampling
Useful when the target behaviour or event is infrequent and could be missed
Limitations of event sampling
If the situation is too busy and there is a-lot of target behaviour being observed
Time sampling
Recording behaviour at timed samples
Strengths of time sampling
The observer has time to record what they’ve seen
Limitations of time sampling
Some behaviours will be missed outside the intervals - not represenative
Strengths of structured observations
The behavioural checklist allows objective quantifiable data to be collected which can be statistically analysed
Limitations of structured observations
Pre- existing behavioural characteristics can be restrictive and doesn’t always explain why its happening
