How is a quasi-experimental research design different from a true experimental design?
In a quasi-experimental design random assignment doesn't/can't occur.
What contributes to a non-experimental research design?
The independent variable is pre-existing and there is no manipulation or intervention.
What is required in a true experimental design?
There must be at least 1 manipulated independent variable
Subjects must be randomly assigned to their group
What is another name for a nomothetic research design?
Group Research Design
What are the 3 group research design strategies?
What is a between-groups research design?
Comparing groups where the groups and data are independent of one another
What is a within-subjects research design?
comparing groups in which the data is related/correlated/repeated
What type of research design is used when two groups of subjects are matched on some characteristic/variable?
What are carryover effects?
Occurs in a within-subjects design when subjects are exposed to multiple conditions and their performance naturally changes
Carryover effects occur in what type of research design?
How should a research counteract carryover effects?
Use a latin square design
What is a mixed research design?
Contains components of both between-groups and within-subjects designs. One component is independent and the other is repeated
What is another name for an idiographic research design?
What is one problem of a single subject research design?
What is the AB research design?
A is baseline
B is treatment
What is the biggest threat to an AB treatment design?
How is an ABAB treatment design better than an AB design?
It removes the threat of history
What is one ethical concern about the ABAB design?
Treatment B may be effective and then you remove it for a return to baseline
What is one general concern about the ABAB design?
Participants may not return to baseline a second time
What is a drawback of a multiple baseline design?
What is a benefit of a multiple baseline design?
Avoids the problems of AB and ABAB designs
What is the simultaneous treatment approach?
Simultaneous treatment occurs, but at two different times of day
What is a changing criterion research design?
Used when gradually trying to change behavior
work towards achieving a criterion and the criterion changes as time progresses
When would you use interval sampling?
When the behavior being measured does not have a specific or identifiable beginning or end
What are the two types of interval sampling?
Whole Interval Sampling
What is momentary interval sampling?
Choose specific times and if the behavior is being exhibited at that time you get a tally
What is whole interval sampling?
Choose and interval of time and only get a check if the behavior is begin exhibited that entire time interval
What is analog research?
Approximates a clinical situation
What is a problem with analog research?
