Research Methods-non-experimental Techniques Flashcards
what is a case study
an in depth study of an individual or small group of people over time
where are case studies usually carried out
in the real world
what do case studies involve the study of
unique or extreme circumstance that cannot be investigated experimentally
what are the 3 research methods used in case studies
psychological testing
observations
interviews
what is psychological testing
IQ testing
what are observations
researchers may observe behaviour in different situations
what are interviews
to find out about their circumstances
what sources can be used during the interview
the individual themselves
family and friends
key word to describe case studies + definition
idiographic meaning individualistic
what is the opposite of idiographic + meaning
nomothetic meaning general laws of behaviour
key word to describe case studies as being over a long period of time
longitudinal meaning changes to behaviour can be observed over time
Strengths of case studies
(concerned with data)
they provide a large amount of quantitative and qualitative data and therefore detailed understanding of the behaviour
case studies involve several methods which allows us to triangulate data enabling checks for validity and reliability
Strengths of case studies
(reflecting real life experiences)
case studies are more ecologically valid
they reflect real life experiences
strength of case studies
(heuristic)
a single anomalous case may lead to revision of a theory
this means they have heuristic value
what does heuristic mean
potential to stimulate or encourage further thinking
limitation of case studies
(involving the study of a small amount of people)
case studies involve the study of a small amount of people so its not possible to make
generalisations-as each persons brain is unique
reliability-as you can replicate them
limitations of case studies
(large amount of data)
they generate large amounts of data so they have to be selective in the aspects they report
they are likely to pick data that supports their hypothesis
thus introducing the possibility of researcher bias
which decreases validity
limitations of case studies
(memories)
we have to rely on peoples memories to find out what the individual was like before the incident
people memories are unreliable to we are unsure for certain what they were like before the event so we cant draw firm conclusions from it
limitations of case studies
(subjective)
there are problems around the subjective interpretation of the findings so may lack validity
what are the ethical issues linked to case studies
confidentiality-because of the individuals unique characteristics they may be identified
however it is important to to retain anonymity because
-they may be embarrassed if people can identify them
-may be treated badly by people
may lead to psychological harm
what are observational techniques
observational techniques involve observing actual behaviour which are subsequently scored
what do the behaviours need to be so that the researcher can observe them
operationalised-so that the observer knows what to look out for and measure
eventually these can be counted(through tallying) to produce a score
what is a controlled obervation
where a researcher attempts to control certain variables
they can be achieved by carrying out experiments in a laboratory
what is a naturalistic experiment
examines behaviour in a natural setting without the investigator interfering in any way
advantages of a controlled experiment
high control over variables means the experiment can be replicated and reliability can be assessed
the exclusion of extraneous variables allows for greater inference of cause and effect
disadvantages of a controlled experiment
low ecological validity as its carried out in an artificial setting with potential outside interference from the researcher
advantages of a naturalistic experiment
high ecological validity as the researcher records behaviour in the naturally occurring environment without any outside interference from the researcher
disadvantages of a naturalistic experiment
lack of control over variables so the researcher can replicate it to check reliability
what is a participant observation
where the researcher become actively involved in the situation being studied
they take part in the same activities and become a member o that group
what is a non-participant observation
the researcher remains external to those being observed
they remain at some distance
and do not take part in group activities
what are the advantages of participant observation
the researcher can obtain in depth data which improves validity
they are close in proximity to the participant so are unlikely to overlook or miss any behaviour
what are the disadvantages of participant observation
-the researchers presence may impact participants behaviour due to evaluation apprehension
-investigator effects may also be present
-this overall impacts validity
what are the advantages of a non-participant observation
investigator effect and apprehension evaluation are less likely as the researcher is not visible
what are the disadvantages of a non-participant observation
due to lack of proximity the researcher may overlook/miss behaviours of interest which may decrease validity
what is an overt observation
an observation where the observer is clearly visible (not hidden from view)
the participant is aware the observer is studying them
what is a covert observation
the participant does not know they are being observed
if its a participant observation they will pretend to be part of the group
if its non-participant they may observe from a distance
what are the advantages of a overt observations
you can inform participants in advanced and obtain informed consent which is more ethical
what are the disadvantages of a overt observations
behaviour may be distorted through investigator effects in which participant may change there behaviour through social desirability bias
what are the advantages of a covert observation
investigator effects are unlikely meaning that participants behaviour will be genuine which improves validity
what are the disadvantages of a covert investigation
less ethical as particpents are unaware they are taking part so you cannot obtain informed consent
what should you look at when observing behavior
the researcher needs to decide….
-what they are observing
-how often they are observing it
-how they are going to record the data eg-video, photographs, on the spot note taking
