Which statement best defines deception in psychological research?

• A. Information is withheld from participants: they misled about the purpose of the study and what will happen during it.
• B. Participants are fully informed about the aims and procedures.
• C. Participants are allowed to withdraw without penalty.
• D. Researchers reveal all hypotheses before the study.

Answer: (A)

Deception in research means not telling participants the full picture and sometimes giving them misleading information about the study’s aims or what will happen to them. The statement that information is withheld and that participants are misled about the purpose and what will happen best captures this idea, because it directly describes both withholding details and presenting false or incomplete information about the study. Being fully informed about aims and procedures isn’t deception, so that option isn’t correct. Allowing participants to withdraw is an ethical right, not a description of deception, and revealing all hypotheses beforehand is about transparency and reducing bias, not deceiving participants. In practice, deception is used only when necessary and followed by thorough debriefing.
