What would you do to minimize (or neutralize) the following effects of REACTIVITY for all 150 volunteers in the study [CAUTION: DO NOT LEAVE any question unanswered. You must offer an explanation IF there is an absence of a specific effect)]:

[9.1] Hawthorne Effect

Novelty Effect

Demand Characteristics

Placebo Effect
