1

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.

2

What contributes to a non-experimental research design?

The independent variable is pre-existing and there is no manipulation or intervention.

3

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

4

What is another name for a nomothetic research design?

Group Research Design

5

What are the 3 group research design strategies?

Between-Groups
Within-Subjects
Mixed

6

What is a between-groups research design?

Comparing groups where the groups and data are independent of one another

7

What is a within-subjects research design?

comparing groups in which the data is related/correlated/repeated

8

What type of research design is used when two groups of subjects are matched on some characteristic/variable?

Within-Subjects Design

9

What are carryover effects?

Occurs in a within-subjects design when subjects are exposed to multiple conditions and their performance naturally changes

10

Carryover effects occur in what type of research design?

Within-subjects

11

How should a research counteract carryover effects?

Use a latin square design

12

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

13

What is another name for an idiographic research design?

Single Subject

14

What is one problem of a single subject research design?

Autocorrelation

15

What is the AB research design?

A is baseline
B is treatment

16

What is the biggest threat to an AB treatment design?

History

17

How is an ABAB treatment design better than an AB design?

It removes the threat of history

18

What is one ethical concern about the ABAB design?

Treatment B may be effective and then you remove it for a return to baseline

19

What is one general concern about the ABAB design?

Participants may not return to baseline a second time

20

What is a drawback of a multiple baseline design?

Time Consuming
Expensive

21

What is a benefit of a multiple baseline design?

Avoids the problems of AB and ABAB designs

22

What is the simultaneous treatment approach?

Simultaneous treatment occurs, but at two different times of day

23

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

24

When would you use interval sampling?

When the behavior being measured does not have a specific or identifiable beginning or end

25

What are the two types of interval sampling?

Momentary Sampling
Whole Interval Sampling

26

What is momentary interval sampling?

Choose specific times and if the behavior is being exhibited at that time you get a tally

27

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

28

What is analog research?

Approximates a clinical situation

29

What is a problem with analog research?

Limits generalizability

30

What are the three time frames of research design?

Cross-Sectional
Longitudinal
Cross-Sequential
