A researcher measures time on task behavior for a student who has been referred by their teacher. Then the researcher implements a new reward system for the student to determine if the reward system increases time on task behavior. Time on task behavior is then measured a second time without the treatment to determine if the behavior returns to pretreatment levels. This study uses a ______ design.
A) A-B-A-B
B) discrete trials
C) A-B-A
D) both A-B-A-B and discrete trials

The described study uses an A-B-A design, where "A" represents the baseline measurement (time on task behavior before the intervention), "B" represents the intervention phase (implementation of the new reward system), and the second "A" represents the return to baseline (measuring time on task behavior a second time without the treatment to see if it returns to pretreatment levels).
