Observations(research methods) Flashcards
What is an observation ?
A research method where no variables are manipulated and ppts are watched and their behaviour is recorded
Used as a technique to record behaviour in experiments
What are the two types of observation
Participant observation
Non participant observation
What is participant observation
The observer acts as part of the group being watched
Non- participant observation
The researcher does not become part of the group being observed
Participant observation strengths
Insight into ppts emotions and motives
Ppts may be unaware so high internal validity- natural behaviour
Weaknesses of ppt observation
Observers may be subjective as they’re part of the group
Strengths of non-participant observation
Observers can remain objective as they’re not involved
Weaknesses of non- participant observation
If ppts unaware, ethical issues
If ppts are aware , behaviour may change
Covert observation
They don’t know they’re being watched
‘Undercover observation’
Ppts are not aware of being observed
Overt observation
‘Open observation’
Ppts are aware of being observed
Covert observation strengths
Ppts behave naturally
Covert observation weaknesses
Ethical issues
May be difficult to maintain covert status
Overt observation strengths
More ethical
Overt observation weaknesses
Ppts may not behave as they normally do
Naturalistic observations
Observations can take place in a natural situation
Controlled observations
Observations can take place where some variables are controlled and manipulated
Strengths of naturalistic observation
Natural behaviour:
High internal and ecological validity
Useful in situations where it would be unethical to intervene
Strengths of controlled observation
Data recording more reliable- equipment can be used
Control over extraneous variables
Weaknesses of naturalistic observation
No control over extraneous variables
If ppts become aware of the observation behaviour may change - low validity
Weaknesses of controlled observation
Demand characteristics
Unstructured observation
All( relevant) behaviours are recorded
Usually qualitative data
Structured observation
Only selected behaviours are recorded- pre- determined categories
Usually quantitative data
What are behavioural categories
The pre-determined units of behaviour to be observed
What are the two behavioural categories
Verbal
Physical
