research methods - non-experimental methods Flashcards
what are observations?
watching participants and recording their behaviour
why are observational techniques non-experimental?
they have no IV and DV and don’t attempt to establish cause and effect
what is a naturalistic observation?
watching and recording behaviour in a natural situation where the researcher does not influence the situation of participants in any way
strength & weakness of a naturalistic study:
strength - high ecological validity as the environment is normal
weakness - difficult to replicate
what is a controlled observation?
watching and recording behaviour in an environment which has been regulated and controlled by the researcher (eg: lab)
strengths and weaknesses of controlled observations:
strengths - easy to replicate (work can be verified)
weaknesses - low ecological validity (lacks mundane realism)
what is an overt observation?
when participants are made aware that their behaviour is being watched and recorded, regardless of the setting in which they are being observed
what is a covert observation?
when participants are not aware that their behaviour is being watched and recorded
issues with covert observations
participants will not have given their informed consent to take
can using a CCTV recording be covert?
yes
strengths and weaknesses of overt observations:
strengths - more ethical
weaknesses - behaviour changes when observed
strengths of covert observations:
-behaviour is more natural
-less demand characteristics
-less observer effects
weaknesses of covert observations:
-less ethical
-can only observe where you expect to be observed
what is a participant observation?
-the observer is part of the group being observed
-the observer watches the behaviour from within the social situation being studied, acting as one of the group and even interacting with the group being observed
strengths and weaknesses of a participant observation:
strengths - closer to everything that’s going on (deeper understanding of the behaviour)
weaknesses - less objective (the researcher may become too involved | eg: zimbardo)
what are behavioural categories?
dividing a target behaviour (such as stress, aggression or affection) into a subset of specific, observable behaviours
why are behavioural categories used?
in order to produce a structured record of what a researcher sees (or hears
examples of behavioural categories for affection:
‘hugging, kissing, holding hands’
what must behavioural categories be?
clearly ‘operationalised’ and must cover all possible ways the behaviour may occur
how are behavioural categories recorded?
-a table is made that has headings of each behavioural category and frequency
-the researcher can then observe the behaviour by standing in a relevant position and tick the box when each behaviour is shown
benefits of behaviour categories?
-allow observers to tally observations into pre-arranged groupings
-using categories provides clear focus for the researcher
-categories allow for more objective / scientific data recording
-categories provide data that is easier to quantify / analyse
what is observer bias?
when an observer’s expectations influence what they sees/hear/records
ways to record behaviour:
-videos
-1 through 10 scale
-tally
-in the spot notes
observer bias when a scale is used:
if a scale is used, a biased. observer may award a higher score to one party even when the same behavior is used
what is an observational design?
how you will conduct the observation
what is an observational technique?
(+ examples)
the type of observation
(eg: naturalistic, covert)
what is observational sampling?
selecting which behaviours to observe and record
complications with observational selection:
-when should you observe behaviour and how long for?
-it can be very useful to continuously record every instance of a behaviour in as much detail as possible
-however, in many situations, this is not possible as there would be too much data to record
what can be done to remedy the fact that it is difficult to record all behavior at all times?
more systematic sampling procedure can be used
what is event sampling?
continuously watching a certain behaviour (or ‘event’) and counting the number of times that event occurs in a target individual or group
when is event sampling useful?
when a target behaviour or event is quite infrequent and could be missed by time sampling
strengths of event sampling:
-does not miss important behaviour
-good for infrequent behaviours
weaknesses of event sampling:
if there is complex/lots of behaviour, some may be missed due to overwhelming events
what is time sampling?
watching and recording behaviour at specific time intervals (instead of continuously recording)
examples of time sampling:
observing behaviour every 30 seconds
