observation Flashcards
coding frame
- a tally chart which gets filled during a structured observation
- within a coding frame there will be **behavioural categories **
advantages of naturalistic observation
- Participants are in their normal environment so are more likely to show valid behaviours
- Participants less likely to be aware they are being observed so will be genuine
- Useful for obtaining observations in situations where intervention would be unethical, e.g. investigating behaviours in domestic abuse, you may observe couples outside a night club on a Saturday night.
disadvantages of naturalistic observation
- Extraneous variables can rarely be controlled so reduces validity
- Difficult to ensure reliability of data collection, however, this can be overcome by recording behaviours via video tape/camera.
- If observers are identified validity is compromised.
advantages of controlled observations
- Data recording is likely to be reliable becuase there is a specific focus that allows data to be collected in a consistent manner.
- Extraneous variables can be controlled therefore increasing validity.
- Compared to experiments, a much greater range of behaviours can be explored giving a useful insight into human behaviour
disadvantages of controlled observation
- Participants are in an unfamiliar environment so may not react naturally
- Participants will be aware that they are in an artificial situation so they may not react naturally
- Difficult to completely represent the reality of a complex social setting so lacks ecological validity.
advantages of structured observation
- Easier to record as there is a specific focus on certain behaviours. This increases the validity, as the researcher is not distracted by other behaviours, or behaviours that may be irrelevant to the research aim.
- Easier to establish inter-rater reliability. Due to the clear, planned focus on behaviour, the research could be easily used and understood in a consistent way, also improving replicability.
disadvantage of structured observation
- Can reduce validity as there is a clear focus, behaviours that may be important may be missed due to it not being part of the planned behaviours.
- Open to observer bias as the researcher may interpret behaviours in a way that fits into the planned behavioural categories, therefore reducing validity as it may not reflect what actually happened.
advantage of unstructured observation
- Increases validity as the researcher is taking into account all behaviours that are going on. This ensures that more valid conclusions are made of behaviour, as a wide perspective is gathered, not a small focussed one.
- Applicable to a wide range of contexts. This is a key strength as this method is extremely easy to use when collecting data on many different situations of behaviour.
disadvantages of unstructured observation
- Harder to record as the researcher has to pat attention to everything around them, this may cause behaviours to be missed and reduce validity.
- Harder to establish reliability because there is limited focus, therefore if it were to be replicated, the focus is likely to be different in relation to the individual carrying out the observation.
- Open to observer bias as the researcher may only note down behaviours that support their own theories, or behaviours that reflect what they hoped to find.
naturalistic observation
- observing participants in their natural environment, often used when manipulating the environment would be unethical
structured observation
data collection itself is done in a structured manner.
unstructured observation
coding frames or behavioural categories are used all behaviors observed are recorded.
participant observation
when the observer is amongst the participants who are being observed
advantages of participant observation
- Only way to observe some behaviours i.e. cults/gangs
- Greater accuracy and detail as the participant is involved in the behaviour. This allows the researcher to make more valid conclusions about behaviour as they have a greater insight and perspective
weakness of participant observation
- Harder to remain objective as the researcher may get lost in the moment and begin to interpret behaviour at a personal level (building of relationships) which may be more opinionated rather than what is actually happening.
- The presence of the researcher can influence behaviour, reducing validity.
non-participant observation
- The researcher remains separate from the person they are observing:
advantages of non-participant observation
- Easier to remain objective as the participant is away from disrtactions and can remain focused – increasing validity.
- The researcher has less influence on behaviour therefore chances of researcher effect are reduced. The participant is likely to be less influenced by the researcher.
weakness of non-participant observation
- If participants are unaware that they are being observed as part of a non-participant observation, it can raise ethical issues such as consent and the right to withdraw.
- Less detail and accuracy as the researcher is at a distance from the participants, therefore, some behaviours maybe interpreted or recorded inaccurately – reducing validity.
overt observation
Participants know that they are being observed.
advantages of overt observation
- Reduces ethical issues as the participants are aware that they are being observed.
- If observed for long periods of time, people tend to forget about observers and behave more naturally, particularly when being filmed.
disadvantage of overt observation
-i ncrease of social desirability as they are aware of being observed, they may change their behaviour in a way that they feel is favourable to others, which decreases validity.
- Increase chance of demand characteristics, as the participant is aware of the researcher, they may change their behaviour in order to fit in with what they think the researcher wants to see.
covert observation
Participants do not know they are being observed.
advantages of covert observation
- Increases validity as participants aren’t aware of being observed, they are more likely to act naturally.
- Less demand characteristics as the participant isn’t aware of the researcher, there would be less chance of them changing their behaviour to fit in with the researchers expectations.
disadvantages of covert observation
- It creates ethical issues as the participant has not consented to being observed. This makes it difficult to follow other ethics such as right to withdraw, debrief etc.
- If the participant becomes aware of the researchers presence, they may change their behaviour, thus decreasing validity.
