16In the ABA design the first A phase is when the skills are measured without intervention
- ATrue
- BFalse
17In the ABA design the B phase is the condition in which the treatment is withdrawn
- ATrue
- BFalse
18The multiple-baseline-across-subjects design involves several participants who are taught one or more behaviors sequentially (in a staggered fashion) to show that only the behaviors of treated participants change; those of untreated participants do not change.
