Question

​Which of the following is NOT a type of multiple-baseline design?

	a.	​multiple-baseline across time
	b.	​multiple-baseline across behaviors
	c.	multiple-baseline across participants
	d.	​multiple-baseline across situations

Answer 1

The correct answer is (A)- multiple-baseline across time

Multiple-baseline design- It is one of the three types of single-subject experimental research. In this design, several baseline are simultaneously established prior to the administration of treatments.

Types of multiple-baseline design-

1. multiple-baseline across behaviors- in this design the effect of independent variables across several different behaviours emitted by the same participant is evaluated.
2. multiple-baseline across participants- In this design, a treatment is applied in sequence to the same class of behaviour in different participants who are in the same environment.
3. ​multiple-baseline across situations- In this design, the treatment is applied to the same behaviour when the participants are in different environment or conditions.
