Answer to Question 1

(a) You may save a considerable amount of time by testing the same person repeatedly, especially if the testing can be done in a single setting.
(b) You need fewer participants because you don't need to find new people for each condition you want to create.

Answer to Question 2

Delayed debriefing means that participants will not be able to discuss the study with other participants who would then not be naive; these subsequent participants could alter their behavior in light of what they know.
A disadvantage of delayed debriefing is that any negative effects of participation may persist, increasing the risk of physical or psychological harm. In addition, some participants may never learn of deception or of the purpose of a study because they fail to return for debriefing or do not pay attention to information sent by the researcher.
