If you were designing an experiment and needed to avoid using self-report questionnaires to measure participant stress, how could you operationally define and quantify the stress response using specific biological variables?
Question: If you were designing an experiment and needed to avoid using self-report questionnaires to measure participant stress, how could you operationally define and quantify the stress response using specific biological variables?
Sample answer: I could operationally define the stress response by recording specific physiological measures within the body, such as elevated blood pressure levels or increased concentrations of the stress hormone cortisol.
Key points:
- Proposes an operational definition based on physiological measures.
- Specifies recording biological variables within the body to quantify stress.
- Identifies elevated blood pressure as a valid variable to measure in the experiment.
- Identifies increased concentrations of the stress hormone cortisol as a valid variable to measure in the experiment.
Rubric: Full credit is awarded for stating that stress can be quantified by recording biological variables within the body, specifically applying the concepts of elevated blood pressure or increased cortisol levels to the research design.
