Observations Flashcards
Naturalistic observation
Watching and recording behaviour in the setting in which it would normally occur
Naturalistic observation- Strengths
- High ecological validity
- Minimises demand characteristics
- High external validity
- Can be generalised
Naturalistic observation- Weaknesses
- Difficult to replicate
- High risk of extraneous/confounding variables
- Low internal validity
Controlled observation
Watching and recording behaviour within a structured environment- where some variables are controlled
Controlled observation- Strengths
- High internal validity
- Easier to standardise
- Limited extraneous variables
- Allows for standardised procedures
Controlled observation- Weaknesses
- Lack of ecological validity
- Low external validity
- Increased risk of demand characteristics
Covert observation
Participants’ behaviour is watched and recorded without their knowledge or consent
Covert observation- Strengths
- Reduced demand characteristics
- High ecological validity
- High internal validity
Covert observation- Weaknesses
- Ethical issues- consent and confidentiality
- Difficult to replicate
- Potential observer bias
- Data collection may be difficult
Overt observation
Participants’ behaviour is watched and recorded with their knowledge and consent
Overt observation- Strengths
- Ethical transparency
- Reduced observer bias
- Easy to generate and record data
Overt observation- Weaknesses
- Risk of demand characteristics
- Limited generalisability
- May respond in socially desirable way
Participant observation
The researcher becomes a member of the group whose behaviour they are watching and recording
Participant observation- Strengths
- Gain insight into PPs lives
- Increased external validity
- More natural behaviour
Participant observation- Weaknesses
- Researcher may lose objectivity
- Risk of researcher bias
- Ethical concerns
