research methods booklet 2 Flashcards
observational techniques
location
overt/covert
participant/non participant
naturalistic observation
ps observed in their natural environment
normal place of activity
controlled observation
artificial and contrived environment where there has been a set up
overt
participants are aware that they are being observed and informed consent is given before hand
they may use one way mirrors
covert
ps are not aware they are being observed and didn’t give informed consent
expeerimeters are undercover
non participant observation
researcher remains separate from those being observed and is simply a bystander. little/no interaction with the ps
participant observariables
researcher participates in the behaviour being observed and becomes part of group being observed.
design of observations
structured
unstructured
structured observation
more frequent
a system is imposed before can observation is conducted which includes categorising exactly which behavious is to be observed.
unstructured
the researcher freely records all relevant behaviour usually in note form without imposing a system on what is observed
behavioural categories
structured observation
form of operationalising general behaviour into specific components
behaviour sampling
event
time
event sampling
observers record every time a certain behaviour occurs the total number -frequency- of behaviour
time sampling
observers decide on time interval-1min- and records which behaviour occurs at that time
when should event sampling be used
researchers don’t want to miss any behaviours
difficult if there are lots of behaviours
when should time sampling be used
there are lots of behaviours that are likely to occur often
behaviours may be missed
inter observer reliability
second observer is used snd coding done separatly
comparison of two observers will be made to see wethe4r the analysis produces similar results
a correlational analysis will be performed to check similarity
if correlation co efficient is 0.8 then they are similar.
advantages of observations
- higher ecological validity
-naturalistic observations, behaviour is being recorded in ps natural surroundings with nothing being manipulated artificially by researcher
-naturalistic obersvations can be generalised to real life
-low in demand characteristics
-covert observations conducted without participants awareness will not change their behaviour to meet the expectations of the researcher
-behaviour observed in covert observations can be generalised to real life.
disadvantages to observations
-low internal validity
-naturalistic observations no variables are being manipulated and it is often difficult to control extraneous variables such as situational and participant variables
-cant establish cause and effect
- can be affected by observer bias more than experimental methods
-observer may be influenced by their own expectations and subjective interpretations in participant observations where the observer may Develop a relationship with those being observed
-findings may not be reliable
self report key features
- questionnaires are written questions
-questions are pre determined before being administered
-questions can be open or closed
-can be administered in person, post , online , over the phone
open ended Q
doesn’t require a fixed response
answer provides qualitative data
closed ended Q
fixed response
yes/no
quantitative
advantage of questionnaire
-less time consuming
it is possible to email or post questionnaires out in a relatively short period of time to hundreds of participants which can be completed without needing researches present
- More practical compared to inte4rvierws
- more honest with their answers
- they feel more comfortable with revealing personal info so they are less likely to feel uncomfortable
-questionaires may bee more appropriate to use when investigating attitudes and opinions to socially sensitive topics
disadvantages to questionnaires
-more likely to produce bias
-response bias:rush and or fail to read questions carefully.
social desirability bias: may be untruthful with answers if they want to present themselves in a favourable manner.
-means info received from closed ended questions could be unreliable and invalid
-questionaires produce less detailed compared to interviews
-clsoed questions are used, only allowed to select from limited choice of answers, which may not reflect on their true thoughts and feelings and can’t add futher comments
-less meaningful data
