How was the participants’ involvement managed after the monitoring test?

• A. They were given a questionnaire
• B. They were debriefed about the true nature of the experiment
• C. They were allowed to leave immediately
• D. They performed an additional task

Answer: (B)

Participants' involvement was managed through a debriefing about the true nature of the experiment, which served several important purposes. This process allows researchers to disclose the specific aims of the study and clarify any misconceptions participants may have had. It also provides an opportunity to address any ethical concerns, ensuring that participants feel informed and respected regarding their contribution to the research.

This approach enhances the integrity and transparency of the research process, offering participants insight into how their involvement contributes to broader scientific understanding. Moreover, debriefing can help alleviate any potential distress participants might feel about their experience, particularly if the experiment involved elements that could be confusing or misleading.

By contrast, other options do not focus on the participants' understanding of the experiment's purpose and findings. A questionnaire could collect data on participants' experiences but wouldn't necessarily foster an understanding of the study. Allowing participants to leave immediately might neglect the ethical obligation to provide context for their involvement, while performing an additional task would divert attention from important debriefing elements. In essence, the debriefing is an essential part of ethical research practices, ensuring that participants are fully apprised of the study's context.
