observational techniques Flashcards
strengths of controlled observations
- extraneous variables less of a factor so can be replicated easier
What is controlled observations
watching and recording behaviour in a structured environment
weaknesses of controlled observations
- cannot be readily applied to everyday life
- low external validity
what is naturalistic observations
watching and recording behaviour in a setting it would normally occur
what is covert observation
watching and recording behaviour without ppts knowledge
strengths of covert observation
- ensures natural behaviour so increases validity
- no participant reactivity
weaknesses of covert observations
- not ethical
what is overt observations
behaviour watched and recorded with ppts knowledge and consent
strengths of overt observations
- more ethically acceptable
weaknesses of overt observations
- may change their behaviour as they know they are being studied
what is participant observations
researcher becomes member of the group who’s behaviour they are watching
strengths of participant observations
- helps produce a first hand account
- increases validity
weaknesses of participant observations
- chance of bias
what is non-participant observations
researcher remains outside of groups who’s behaviour is being recorded
strengths of non-participant observations
- more objective observations
