observational techniques Flashcards
describe a naturalistic observation
watching and recording behaviour in a setting where it would normally take place
give strengths of a naturalistic observation
- high ecological validity
- high external validity
give limitations of a naturalistic observation
- low ecological validity if ppts become aware that they are being watched
- replication is difficult
- uncontrolled confounding + extraneous variables are presented
describe a controlled observation
watching and recording behaviour in a structured environment eg. lab
give strengths of a controlled observation
- researcher is able to focus on a particular aspect of behaviour
- more control over extraneous variables
- easy to replicate
give limitations of a controlled observation
- more likely to be observing unnatural behaviour as its in an unnatural environment
- low mundane realism so low ecological validity
- demand characteristics
describe an overt observation
ppts are watched and their behaviour is recorded with them knowing they are being watched
give strengths of an overt observation
- ethically acceptable as informed consent is given
give limitations of an overt observation
- more likely to be recording unnatural behaviour
- demand characteristics likely - reduces validity
describe a covert observation
ppts are unaware they are being watched and recorded
give strengths of a covert observation
- natural behaviour recorded hence high internal validity
- removes problem of ppt reactivity where ppts try to make sense of the situation theyre in and guess the aim
give limitations of a covert observation
- ethical issues - no informed consent
describe a participant observation
researcher who is observing is part of the group being observed
give a strength of a participant observation
- more insightful which increases the validity of findings
give limitations of a participant observation
- behaviour may change if they find out theyre being watched
- reseracher may lose objectivity as may start to identify too strongly with ppts
