Answer:
stable-baseline; multiple-baseline; reversal
Explanation:
A stable-baseline design : It is a small N design where the experimenter observes the behavior for a longer baseline period before the beginning of a intervention or other treatment and thus continues observing the behavior after the treatment.
A multiple-baseline design : They are small-N design where the researchers observes the intervention of more than one behavioral type across a variety of time before actually applying treatments to each behavior.
A reversal design : Here a researcher observes a behavior both before as well as during the treatment, and then removes the treatment for a while to see if the behavior returns.
Therefore, the answer is--
stable-baseline; multiple-baseline; reversal
