, Definition:- Observing the behaviour of participants within their own environment, where they would
normally show their behaviours being investigated. Nothing is manipulated/controlled by the researcher Definition: - Observation is staged in some way so the researcher has some control over the situation
Strengths:- A realistic picture of natural, spontaneous behaviour Strengths:- Controlled environment allows focus on particular aspects of behaviour, for example, children playing with ‘feminine’ toys to observe how boys
- The observation takes place in a person’s (or animal’s) natural environment and so they are likely to and girls react
behave as they normally do
- This means that specific conclusions can be drawn about gender responses- if everything was natural the children might not encounter different types of toys
- This means the results are likely t be high in ecological validity
- It may be possible to draw some tentative causal conclusions.
- Useful method to use when investigating a new area of research
- If variables are deliberately changed by the researcher and different effects are observed then it suggests that one caused the
- Gives researcher ideas of what further investigations may be planned, for example using certain
behavioural categories or experimental methods Weaknesses: - Environment may feel unnatural and then participants may not behave as they would in everyday life
Weaknesses: - The observation is more likely to be covert, which raises ethical issues - This means that the ecological validity may lack
- It is difficult to draw conclusions if the focus is too wide - Participants may know they are being observed, for example if the observation takes place in a lab so that the researcher can control aspects of the situation.
- If behavioural categories and event/time sampling have been used that may restrict the amount of - This awareness means that participants may try to guess what the study is about which alters their behaviour
data collected which makes it easier to see patterns of behaviour
Observations Definition: - Where the participants do know that they are being observed
Strengths:- Avoids lack of informed consent because participants can decide whether to participate
Definition: - Where the participants don’t know that they are being observed
Strengths: - Participants behave more naturally because they are not aware of being observed
(learning research - It is easier to see everything that is going on because the observer doesn’t have to hide
Weaknesses:- If the participants know they are being observed they are likely to alter their

- Participants may be able to give informed consent if asked afterwards (and can withhold their
data) but in practice this is difficult
- There is an invasion of privacy issue
- Even for observations in a public place, such as a bus queue, people might regard it as unethical

Definition:
- Where the observer remains detached from the people they are observing
Strengths:
Definition: - Where the observer becomes part of the group that they are observing
- Participants behave more naturally because they are not aware of being observed
Strengths:- Likely to provide special insights into behaviour, from the ‘inside’
Weaknesses:
- The participant has greater familiarity with what is likely to happen and therefore may ‘see’ greater detail that would be missed by someone new to
the situation - Raises ethical issues about observing people without their knowledge
- Being on the inside means the observer may see more.
- Participants may be able to give informed consent if asked afterwards (and can withhold

- There is an invasion of privacy issue
- More difficult to record and monitor behaviour unobtrusively if the observer is part of the group being observed.
- Even for observations in a public place, such as a bus queue, people might regard it as
- Therefore, the observation is likely to be overt and participants are aware they are being studied, which may alter their behaviour
