Chapter 13: Descriptive Research Strategies Flashcards
descriptive research
measuring a variable or a set of varaibles as they exist naturally.
do descriptive research methods explain causal relationships?
no
3 types of descriptive research design
1) observational research
2) survey research
3) case study research
in an observational reserach design, researchers ___ and ___ record the behavior of individuals.
in an observational reserach design, researchers OBSERVE and SYSTEMATICALLY record the behavior of individuals.
typically, observational research designs observe overt ___
behavior
problems with behavioral observation
1) reactivity: is it important to not disrupt or influence the behaviors of the people being studied
2) subjective interpretation: there may be observer bias because researcher may selectively report behavior.
Solutions to reactivity:
you could conceal the observer (ethics)
you could allow for habituation time: repeated exposure until the observer’s presence is no longer a novel stimulus
habituation
repeated exposure until the observer’s presence is no longer a novel stimulus
solutions to observer bias and subjective interpretation
1) operantly define behaviours
2) well trained observers that are not associated with the study
3) calculating inter-rater reliability: calculating the correlation of agreement between observers’ scores
three methods in quantifying behavioral observations
1) frequency method: counting instances of behavior in a fixed period
2) duration method: recording how much time an individual spends engaged in a behavior
3) interval method. dividing the observation period into a series of intervals and then recording whether a specific behavior occurs during each interval.
unlike frequency or duration methods, interval methods of quantifying behavior allows researchers to ___ both frequency and duration into a more ____ measurement.
interval methods of quantifying behavior allows researchers to BALANCE both frequency and duration into a more REPRESENTATIVE measurement.
in complex situations, one method of observation is ___
sampling observations, where researchers record what is happening for further study of multiple variables later on
how to take good sample observations in complex situations? (3 different methods)
1) time sampling: observe record observe record
2) event sampling: identify a specific event or behaviour to be observed and recorded during the first interval, and then focus on a different behaviour on the next interval.
3) individual sampling: identify one participant to be observed during the first interval, then a different individual for a second interval.
how is content analysis/archival research conducted
applying techniques from behavioral observation to situations that do not involve direct observation of behaviors
content analysis
measures the occurrences of events in literature or texts that present replicas of a certain behavior
archival research
looking at historic records to measure behaviours of events that occurred in the past
overall measurement process of a non complicated observation
1) establish behavioral definitions
2) use the frequency method, the duration method or the interval method to obtain and quantify the behavioral data
3) use multiple observers to increase inter-rater reliability
three main types of behavioural observation
1) naturalistic observation
2) participant observation
3) contrived observation
what is naturalistic observation?
aka non participant observation. study behaviour in a natural setting without intervening anyway. researcher tries to be as unobtrusive as possible.
pros and cons of naturalistic observation
pros: can be used to describe any behavior
- insight into real-world behavior
- high external validity
- good at examining behaviors hat cannot ethically be manipulated
cons: time consuming
- extra care needed to not disturb the natural behavioral dynamic.
what is participant observation? when is this used?
researcher becomes part of the study group. used when it is not possible for the researcher to be inconspicuous
- used with under cover cops
pros and cons of participant observation
pros: you can observe behavior not usually open to inquiry
- high external validity
cons: time consuming
- potentially dangerous
- cop or researcher may side with the people of study and no longer remain objective
