Questions: Formulating Research Questions with Specificity

Question 1

A researcher is interested in 'the effect of sleep on academic performance.' Which revised question best demonstrates how specificity entails the study design?

• A. 'Does sleep affect college students?' — narrows by adding a population
• B. 'Does restricting nightly sleep from 8 to 6 hours impair next-day exam scores in undergraduate students?' — specifies the IV, DV, population, and context
• C. 'Is sleep important for learning?' — simpler language makes it more directly testable
• D. 'Does less sleep hurt grades?' — broad enough to be significant and capture all relevant effects

Answer: (B)

Option B is the only one that implies a complete design: the independent variable (sleep restriction from 8 to 6 hours), the dependent variable (exam scores), the population (undergraduates), and the context (next-day effects). A well-formed question entails its design — you can read off what to measure, who to study, and what to compare. The other options add one element of specificity but leave the design underspecified.

Question 2

During a literature review, a researcher discovers that their initial research question has already been answered in three published studies. The best response is to:

• A. Abandon the question and choose a completely different topic
• B. Refine the question to address a specific gap those studies left — such as a different population, condition, or measure not yet examined
• C. Proceed with the original question anyway, since independent replication is always the most valuable contribution
• D. Broaden the question so it no longer overlaps with prior work

Answer: (B)

Finding prior work is expected and desirable — it means you are working in an active area. The response is to refine, not abandon. A question that builds precisely on a gap in the literature ('prior studies only examined acute stress; none have examined chronic stress') is stronger than one generated from curiosity alone. Broadening the question (option D) moves backward toward less specificity, making the design harder to execute, not easier.

Question 3

A broader, more general research question is automatically more scientifically important than a narrow, specific one.

• T. True
• F. False

Answer: False

This is a persistent misconception. Narrow, focused questions often have greater practical impact because they are falsifiable, designable, and clearly positioned relative to prior work. 'Does acute cortisol elevation impair free recall in healthy adults?' can be answered definitively. 'Does stress affect cognition?' can always be answered 'it depends' — which produces no traction for building knowledge. Importance comes from the question's ability to advance understanding, not from its breadth.

Question 4

The specificity of a research question directly determines what design, measures, and analyses are appropriate for investigating it.

• T. True
• F. False

Answer: True

This is the central insight of the topic. A specific question entails its design: 'Does acute cortisol elevation — induced by a standardized social evaluative threat — impair free recall of neutral word lists in healthy adults?' directly implies an experimental cortisol manipulation, a free recall task with neutral stimuli, and a healthy adult sample. Conversely, a vague question leaves every downstream decision underdetermined, producing an incoherent study because there is no principled way to choose among the many possible designs.

Question 5

Why does a vague research question — such as 'Does stress affect cognition?' — fail to produce a coherent study, even when the general topic is scientifically important?

Model answer: A vague question fails to constrain any downstream decision: What kind of stress? What aspect of cognition? Who are the participants? Under what conditions? Without these specifications, there is no principled basis for choosing a design, selecting measures, or deciding what comparison to make. Furthermore, a vague question can always be answered 'it depends' — which advances nothing. Only a specific question can receive a clear yes or no answer, each of which places a definite finding in the literature.

The iterative narrowing process — 'What specifically? In whom? Under what conditions?' — forces every decision that would otherwise be arbitrary into the question itself. The design then follows logically rather than being chosen ad hoc. This is why question formulation is where the quality of a study is determined: all the rigor of methods and analysis cannot compensate for a question that was never specific enough to be falsifiable.
