week 10 - observational methods Flashcards
What are observational methods?
-
observing a relatively unconstrained segment of individuals’ freely chosen behaviour within a particular setting
- no request for information
- no intervention or manipulation of observed behaviours
What is the use of the term “observational” in research methods?
- can refer to the techniques of making observations
- used as a general description, referring to all non-experimental studies where observation is the main procedure for data gathering in natural situations (observation is the overall design)
What is the distinction between technique and overall design?
distinction based on the centrality of “observation” in the research design
Technique:
- measures the dependent variable
- often used within traditional experimental designs in lab settings
- may or may not be part of an experiment
Design:
- relies primarily on observational records
- study that is solely observational and does not include experimentation
How is observation used as a technique, and what is an example?
- used in a lab setting (field experiments are also possible) in addition to other forms of data collection
- i.e. Milgram’s obedience experiments
- Bandura’s Bobo doll experiment (traditional experimental design in a lab setting)
- Rabinowitz et al. (1993) study of store cashier behaviour (field experiment)
What are the advantages of using observation as an overall design?
- produces data on real behaviour rather than possibly distorted self-reports
- can gather data on behaviour not open to experimentation (e.g., real playground aggression)
- if conducted in field settings, can often gather data on unforced behaviour
What are the disadvantages of using observation as an overall design?
- people’s behaviour can be affected by awareness of being observed
- can be very time-consuming compared with the experiment or questionnaire study
- it may not be possible to identify cause and effect
What is controlled observation?
- Observation in a controlled setting, often a lab or observation room
- artificial, potentially inhibiting atmosphere
- limits external validity: how well are the results of the study able to apply to other settings?
What is naturalistic observation?
- observation of people without intervention in their own environment
- access to genuine behaviour, high levels of external validity
What is participant observation?
- The observer acts in the observed group
- qualitative approach to observation
- researcher is an active participant
What is non-participant observation?
- observation from a distance, no interference with the behaviour being observed
- structured and quantitative approach to observation
- researcher is completely uninvolved
What is disclosed vs undisclosed observation?
- distinction based on whether or not the researcher has disclosed to participants that they are being observed for research purposes
- information given can be partial, or can involve some amount of deception, in order to encourage more genuine behaviour
What are the ethical issues of undisclosed (covert) observation?
- obtaining informed consent from participants before the start of the research
- giving participants the option to opt-out of the study
What are some advantages to undisclosed (covert) observations?
- protecting the researchers from harm
- allowing access to sites that otherwise would have not been possible to study
What are Reactivity Effects?
- tendency to alter behaviour in response to awareness of being observed
What are the ways to eliminate reactivity effects?
- the use of hidden cameras
- introduces ethical problems
- impossible when researcher wants to investigate behaviour in home settings
- can reduce reactivity by becoming a predictable and familiar part of the environment
- e.g. several visits to children in their schools without collecting any data
