What are the two main types of experimental designs?

Groups

Single case/subject designs

1

Large groups designs can be ____ subjects or ____ subjects

Between; within

2

Between subjects:

Subjects randomly assigned to experimental/control groups to determine effect of I.V.

3

Within subjects:

Involves repeated measures. Pts sit all conditions and and all results are compared across conditions

4

Single case designs are ____-subject designs. The participant acts as his/her own ____ group

Within; control

5

Give one advantage of using group designs

Less likelihood of extraneous variables affecting the D.V. (e.g. Individual differences)

6

Give one advantage of using single-subject designs

Tells us more about individual behaviour (where groups designs only show us group averages)

7

Behaviour is an ____ phenomenon. What is true of 1 person...

Individual; may not be true for another

8

Behaviour is a ____ phenomenon. It is not static, which is why ____ ____ are so important

Continuous; repeated measures

9

A limitation of single case designs is that

Studies involving small groups of people will not have much external validity (problematic from a research perspective)

10

____ is key to demonstrating external validity in single case designs

Replication

11

What are phase lines?

The lines drawn on graphs to separate baselines and interventions

12

What are phase labels?

Labels explaining what each part of the graph indicated e.g. Baseline, treatment 1

13

Units of time are located on the ____

X-axis

14

The percentage/frequency of behaviour is shown on the ____

Y-axis

15

Before implementing treatment baseline data should be

Stable

16

Baseline data is considered stable if ____ - ____% of the data points fall within ____% of the mean

80;90;15

17

Design that shows the effects of the I.V. by systematically removing it and returning to baseline

ABAB/Reversal

18

When should the ABAB design be used?

When behaviours are likely to reverse and aren't dangerous to others

19

Design that staggers the I.V. across people, settings and behaviours

Multiple baseline

20

Using the multiple baseline design requires taking

At least two baselines for different people or behaviours or settings

21

When should multiple baselines be used?

When multiple, independent elements exist within the experimental settings

When reversal is dangerous/impossible

22

Design that rapidly and randomly switches between I.V.s, allowing simultaneous comparison of treatments to baseline.

Alternating treatments

23

In alternating treatments designs the I.V.s are ____ assigned to days, times etc.

Randomly

24

When should alternating treatments design be used?

When you have >1 intervention to compare

25

Give on advantage to using alternating treatments design

Allows you to choose best treatment out of choice

26

Alternating treatments design requires that treatments are ____ of one another

Independent (treatments should have no carry-over effects)

27

A variation of the reversal design that compares two or more I.V.s by individually comparing them to baseline

ABAC... (With more I.V.s can proceed to D, E, F etc.)

28

In ABAC designs, A = ____, B = ____, C = ____

Baseline; I.V. 1; I.V. 2

29

Experimental design: involves baseline and treatment phase, but the treatment changes as successive goals are met (goals increase as behaviour increases)

Changing criterion design
