I have no such paper, I don't know of any study. I believe I employed the phrase "under lab conditions" as well as the word "question". Allow me to try to resolve your confusion:
ques·tion
n.
1. a. An expression of inquiry that invites or calls for a reply.
b. An interrogative sentence, phrase, or gesture.
2. A subject or point open to controversy; an issue.
