The multiple-baseline design is used to evaluate the effects of a treatment on two or more behaviors or situations of a single subject. In this case, Amelia applied the reinforcement program to two different behaviors (brushing teeth and going to bed on time) before adding a third behavior (reading books) to the program. Therefore, it is an example of an Across behaviors multiple-baseline design.
