What is an observation?
An observation is when a researcher watches or listens to participants engaging in whatever behaviour is being studied.
Types of observations
- Non-Participant observation: When researcher does not get directly involved and does not take part in activities.
Pos: Can focus on activity and make good notes.
Neg: Can’t look out of place + demand char. - Participant Obs: Researcher is directly involved w/ interactions and will engage.
Pos: Greater validity as greater understanding.
Neg: Might become too subjective and biased. - Covert: Undercover and don’t reveal true identity; group doesn’t know.
Pos: less demand char.
Neg: Can break ethics - Overt: Group knows they’re observed by psychologist. Observer effects can occur = invalid results.
Pos: no deception.
Neg: demand char.
Naturalistic Observation
Researcher observes participants in their own natural environment and there is no deliberate manipulation of IV.
Naturalistic Observation: Advantages
- Participants are unaware = less observer effects = valid.
- High mundane realism and ecological validity.
- Useful when the deliberate manipulation of variables is impractical or unethical e.g telling children to be aggressive to observe children in playgrounds vs observing natural aggression.
Naturalistic Observation: Disadvantages
- Impossible to have control over extraneous variables.
- Problematic to determine cause of behaviour.
- Risk of observer bias as observer might be biased trying to interpret behaviour to fit aim.
Controlled Observations
Researcher observes participants un a controlled environment and this allows for manipulation of the IV.
Controlled Observations: Advantages
- Cause and effect can be determined as observation is highly controlled.
- Extraneous variables can be controlled for = results more valid
- Yields qualitative data that is rich and detailed = increases validity as observation is more accurate.
Controlled Observations: Disadvantages
- Lower mundane realism and ecological validity as high control.
- Observer effects can occur as participants know they are being observed (overt). Participants may show social desirability bias and might behave unnaturally.
- Risk of observer bias when observer’s views influence data collected.
How to check observer reliability?
- A way to check this is to have 2 observers who record separately and then correlate observations and data.
- If a Kappa score showing correlation of +0.8 is gained then data is reliable. This is knows as INTER-RATED RELIABILITY.
Behavioural categories
These are specific types of behaviour that are being looked for in an observation.
Sampling procedures
- Event sampling: observer decides in advance what types of behaviour they are interested in and records all occurrences; other types are ignored.
- Time-interval sampling: observer decides in advance that observation will take place only during specific time periods and record the occurrence of specified behaviour during that period.
Pilot study
- Preliminary small scale investigation involving few people to trail the study on. This saves time and money by identifying any flaws in procedure that can be rectified before main study.
- Pilot study can help spot confusion or unusual things in info given.
- Pilot study can be sed to establish behavioural categories and check if they are suitable.
