BCABA Experimental Design and Research Methods

Question 1

Which experimental design involves repeatedly alternating between baseline and treatment conditions to demonstrate experimental control?

Accepted Answer

Reversal (ABAB) design

Answer

The reversal (ABAB) design demonstrates experimental control by withdrawing and reinstating treatment and observing corresponding behavior changes.

Question 2

In a multiple baseline design across behaviors, a functional relation is demonstrated when:

Accepted Answer

Behavior changes only when the intervention is introduced to each successive behavior

Answer

Staggered introduction of the intervention to each behavior, with change occurring only at that point, demonstrates experimental control in a multiple baseline design.

Question 3

The alternating treatments design (ATD) is most useful for comparing:

Accepted Answer

Two or more treatments within the same participant

Answer

The ATD rapidly alternates two or more conditions within the same participant, allowing direct comparison of treatment effects.

Question 4

In single-subject research, 'experimental control' is demonstrated when:

Accepted Answer

Behavior changes reliably correspond to changes in the independent variable

Answer

Experimental control means that the independent variable (treatment) is the reason for observed behavior change, shown through systematic replication.

Question 5

A changing criterion design is particularly well suited for:

Accepted Answer

Shaping behavior toward a terminal goal in graduated steps

Answer

The changing criterion design demonstrates control by requiring behavior to match each successively more stringent criterion before advancing.
