2. Observations Flashcards
How many types of observations are there?
8
Which types of observation refer to where the observation is conducted?
- Naturalistic - takes place in the p’s natural environment
- Controlled - takes place in some form of controlled environment which allows control over variables
Which types of observation refer to how the data is collected?
- Structured - the data would be gathered using a pre-written behaviour categories
- Unstructured - researcher uses direct observation to record behaviours as they occur
Which types of observation refer to what part the observer takes on?
- Participant - the researcher joins in with the group and their behaviour
- Non-participant - researcher doesn’t participate with group, just observes
Which types of observation refer to the participants knowledge
- Overt - p’s are aware they are being observed
- Covert - p’s aren’t aware they are being observed
What are the strengths and weaknesses of controlled observations ?
- S- High levels of control over extraneous variables, meaning that it is easy to replicate and test for reliability
- W- demand characteristics may be present
- low ecological validity
What are the strengths and weaknesses of naturalistic observations
- S- High levels of ecological validity
- p’s often unaware so minimises demand characteristics
- W- no control over extraneous variables
- if p’s are unaware it raises ethical issues
What are the strengths and weaknesses of participants observations
- S- allows researcher to observe data that would otherwise be out of their reach
- high ecological validity
- W- may make observations more subjective
- may alter behaviour being recorded if overt
What are the strengths and weaknesses of non-participant observations
- S- reduces observer bias/chance researcher will affect behaviour
- able to use checklist (behaviour categories) instead of memory
- W- harder to observe all p’s equally due to distance
- only certain categories of behaviour that will be observable
What are the strengths and weaknesses of covert observations
- S- high ecological validity as it doesnt alter p’s behaviour
- W- ethical issues - unaware of being observed = lack of informed consent
What are the strengths and weaknesses of overt observations
- S- eliminates possible ethical issues of observing without consent
- W- danger of reducing validity/demand characteristics
What is time based sampling?
- observer records at regular time intervals
- target person is chosen and watched for a fixed amount of time - behaviour is recorded
- after this they wait for a fixed interval and then either watch them again or watch a new person
What are the strengths and weaknesses of time based sampling?
- S- provides consistent data - if lots was going on it would be hard to record all behaviours
- W- not all data is recorded - key behaviour may be missed
what is event based sampling
- observer decides in advance what type of behaviours they are interested in
- develops a coding system
- records everytime that particular behaviour occurs
- behaviour is recorded continuously
What are the strengths and weaknesses of Event based sampling?
- S- all data is recorded so key data should not be missed
- W- if there’s lots going on, it’s very difficult to record every event/behaviour
