research methods part 2 Flashcards
what is an observation?
experimenters will observe behaviour and record it they will look for patterns in behaviour
what are the advantages of an observation?
what people say they do then what they actually do is often different so observations give us a different take on behaviour than other methods
what are the disadvantages of observations?
observers may ‘see’ what they expect to see (researcher bias)
observations cant provide information about what people think or feel
what is behavioural categories?
it separates a continuous stream of action into components the categories are arranged in a list with a code called a coding frame
what are the advantages of behavioural categories?
it helps enable systematic observations to be made so information isn’t over looked
what are the disadvantages of behavioural categories?
they may not cover all possibilities so some may not be recorded which will lower validity
poorly designed coding will also reduce reliability
what is event sampling?
this is whemmn you draw up a list of behavioural categories then they count how many times they are ibserved over a specicif time period
what is time sampling?
this is where you record behaviour at specific intervals like 5 seconds or 5 minutes or you can take a sample at diffrent times of they day or months
what are the advantages of time and event sampling?
both methods help make the task more manageable because it avoids them having to record everything
time allowed to track time related changes in behaviour
what are the disadvantages of time and event sampling?
some behaviours may be missed reducing validity
it may nit be representative
what is a controlled observation?
it is structured and certain things in the environment are controlled meaning some variables are manipulated by the researcher
what are the advantages of controlled observations?
a controlled environment allows focus on a particular aspect of behaviour
what a disadvantage of controlled observations?
the environment may feel unnatural and participants behaviour may change reducing validity
what is a naturalistic observation?
unstructured everything is left as normal
what are the advantages of a naturalistic observation?
its a realistic environment with spontaneous behaviour which mean it will have a high ecological validity
what is a structured observation?
a system is used to restrict and organise the collection of information
what are the advantages of a structured observation?
improves inter-rater reliability because the observer can be more consistent
what are the disadvantages of structured observation?
observers may ‘see’ ;hear’ what they expect to see or hear
what is an unstructured observation?
observer records all relevant behaviour and has no system
what are the advantages of an unstructured observation?
it is useful when the behaviour which is being studied is largely unpredictable
used in initial investigation’s (pilot study )
