Based on the case context, explain how the researcher can apply the principle of hypothesis concealment. In your explanation, identify how the researcher can balance this approach with the ethical requirements of informed consent, and suggest an appropriate way to label the study materials.
Case context: A researcher wants to investigate how a person's level of anxiety affects their performance on cognitive memory tasks. If participants know the study is about anxiety, they might alter their performance or report their anxiety differently due to demand characteristics.
Question: Based on the case context, explain how the researcher can apply the principle of hypothesis concealment. In your explanation, identify how the researcher can balance this approach with the ethical requirements of informed consent, and suggest an appropriate way to label the study materials.
Sample answer: The researcher can apply hypothesis concealment by withholding the specific focus on 'anxiety' and memory performance. Ethically, they must describe the tasks participants will complete (e.g., memory puzzles or surveys), but they do not need to state that they are measuring anxiety's effect. To prevent signaling the underlying construct, they can label the materials with a generic title like 'Memory and Task Performance Study' or leave the materials untitled.
Key points:
- Identify that the study's specific focus on anxiety should be withheld to minimize demand characteristics.
- Explain that informed consent is satisfied by describing the memory tasks the participants will perform.
- Suggest using a generic study title or leaving the materials untitled to avoid signaling the anxiety construct.
Rubric: Evaluate the response on: (1) Demonstrating comprehension of hypothesis concealment by applying it to the anxiety study. (2) Explaining how to meet informed consent requirements (disclosing tasks but not expected outcomes/hypotheses). (3) Proposing a generic title or untitled approach to minimize demand characteristics.
