Observational techniques Flashcards
Strength of covert observation
Investigator effects are less likely so less chance of demand characteristics so behaviour will seem more natural and representative
Covert observations
Consists of observing people without their knowledge e.g one way mirror
Weakness of covert observation
Ethical issues - participants not aware they are taking part in observation so can’t give consent
Overt observation
Participants know they are being observed e.g filming publicly
Strength of overt method
More ethical than covert, so representation of psychological research as ethical is protected
Weakness of overt observations
Investigator effects so they change their behaviour through demand characteristics , not authentic natural behaviour being observed
Investigator effect
bias occurs when the investigator influences the behaviour of the participants in a way that’s not intended e.g facial expressions
Participant observation
Person who is conducting the observation also takes part in the activity
Strength of participant observation
Researcher can obtain in depth data since they’re in close proximity
Unlikely to overlook behaviour so allows comprehensive understanding
Weakness of participant observation
Investigator effect, changing behaviour through demand characteristics
Natural behaviour not observed so reduced internal validity
Internal validity
Extent to which a piece of evidence supports a claim, within the context of a particular study
Non participant observation
Person conducting experiment doesn’t take part
Strength of non participant observation
Investigator effects less likely to occur as investigator observes from a distance, representative of natural and unaltered human conduct
Naturalistic observation
Carried out in an unaltered setting, observer does not interfere in any way e.g shopping centre
Strength of naturalistic observation
Higher level of ecological validity, reflecting spontaneous behaviour that may occur
Ecological validity
Measure of how test performance predicts real world behaviour
Weakness of naturalistic observations
Issues with reliability, the test- retest method cannot be used of checking reliability
