A researcher is conducting a study on reaction time. They ensure that every participant uses the exact same computer monitor with a response delay of exactly milliseconds. Apply the concept of a constant to explain what this monitor response delay represents in this design, and state whether the researcher can use this delay to explain why some participants had faster reaction times than others.
Question: A researcher is conducting a study on reaction time. They ensure that every participant uses the exact same computer monitor with a response delay of exactly milliseconds. Apply the concept of a constant to explain what this monitor response delay represents in this design, and state whether the researcher can use this delay to explain why some participants had faster reaction times than others.
Sample answer: The monitor response delay represents a constant in this design because it does not vary across participants or situations. The researcher cannot use this delay to explain differences in reaction times because a constant does not change and therefore cannot account for variation in participant performance.
Key points:
- Identify the monitor response delay as a constant in this design.
- State that constants do not vary across individuals or situations.
- Explain that the constant cannot account for variation or differences in participants' reaction times.
Rubric: The response must identify the monitor delay as a constant, state that it does not vary across participants, and explain that because it is a constant, it cannot be used to explain differences or variation in the reaction times.

Example of a Constant: Speed of Light
Which of the following best describes a constant in the context of research?
In a research study investigating the impact of sleep deprivation on test performance, if every participant is given the exact same 30-minute window to complete the test, the 'time allowed for the test' is considered a constant in that study.
A researcher ensures that every participant in a memory study uses the exact same model of computer and the same software version to complete their tasks. In this research design, the 'computer model' is a(n) ________ because its characteristics do not vary across any of the individuals or situations involved.
A researcher investigates if the color of a room affects creativity. They test 40 students: 20 in a blue room and 20 in a red room. All students are given the same 10 minutes, the same box of 64 crayons, and the same drawing paper. Match each element of this study to the analytical description that best explains its role as a constant or a non-constant.
A researcher is evaluating a study on how study-break duration affects memory. They notice that every participant used the exact same -inch laptop screen. Arrange the logical steps the researcher should take to evaluate whether the 'laptop screen size' should be a focus of their statistical analysis, starting from the initial observation.
In psychological research, a constant is a property or quantity that varies across different individuals or situations.
A researcher designs an experiment to study how different room temperatures affect participants' memory recall. In this study, every participant is tested in the exact same room, using the exact same style of chair and desk. Why are these identical environmental factors considered constants rather than the primary focus of the psychological research question?
A researcher studies whether background music (classical vs. silence) affects reading comprehension scores. All participants sit in the same room kept at 68°F, complete a 20-minute reading task, and are timed with equipment that relies on the fixed speed of light. Match each study element to its correct classification.
A student proposes a psychology study with the question: 'Does the speed of light influence how quickly participants respond to a flash of light in a lab?' A faculty advisor explains that the speed of light cannot serve as an independent variable because, unlike phenomena that psychological research typically examines, the speed of light _____.
A peer reviewer is evaluating a published study on how caffeine dose (0 mg, 100 mg, 200 mg) affects reaction time. The authors list 'room lighting' and 'chair height' as constants, but the reviewer suspects one of them actually varied across participants. Arrange the reviewer's evaluation steps in the correct logical order.
Define a constant in the context of scientific research, identify the specific example of a constant mentioned in the research methods text, and explain why constants are not the primary focus of psychological research questions.
Diagnose the issue with the student's proposed research question. Explain what role the room temperature plays in this design, and justify why it cannot be the focus of the research question.
