1.1 Observations Flashcards
Naturalist Observation
Observation that is carried out in the field e.g. Set up in natural settings to give the chance to observe natural behaviour
Advantages of Naturalist Observation
- Observe normal realistic behaviour as participants are in their normal environment and less likely to be aware they are being observed (ecological validity)
- Useful for obtaining information in situations where corporation would be unlikely
Disadvantages of Naturalist Observation
- Lack of control meaning there could be other factors influencing the behaviour decrease in internal validity
- Difficult to ensure data collection is accurate as recording equipment would be obvious (if observers identified- threat to validity)
Controlled Observation
Observation that controls all the possible factors which might alter behaviour, which therefore might hide/confound the behaviour caused the IV
Advantages of Controlled Observation
- Controls other factor that could influence the behaviour, increase in internal validity
- Data recording is likely to be reliable as equipment can be used without having to hide it
Disadvantages of Controlled Observation
-Artificial setting so decrease in ecological validity
High chance of demand characteristics
-participants are in an unfamiliar environment (controlled) so may react differently from how they normally would
Overt Observation
Observation where participants know they’re being observed because of observers presence or they have given consent
Advantages of Overt Observation
-Makes it possible to carry out ethical research, as she/he has given consent to be observed or aware of it
Disadvantages of Overt Observation
-Demand characteristics may occur as participants know they’re being observed, decrease in internal validity
Covert Observation
Where participant doesn’t know they’re being observed
Advantages of Covert Observation
-Natural behaviour can be observed, participants won’t respond to demand characteristics
Disadvantages of Covert Observation
- May not be ethical reasearch as participants haven’t given consent or know they’re being observed as well as not given a right to withdraw
- if observers also participant observer as it may be difficult to record data accurately without increasing the chance of demand characteristics
Structured Observation
When a structure is imposed on the observation to meet the aim of the investigation and the observational systems used for recording the data
Advantages of Structured Observation
- Increased usefulness and objectivity of the study
- behavioural categories can be developed in the pilot study before the observation begins to be certain they include all key actions/ behaviours for the hypothesis
Disadvantages of Structured Observation
- At risk of missing important information so data is limited
- total number of behaviours within a category may be meaningless without the context in which they occurred (decrease in internal validity)
