Suppose you are designing a new study to measure public speaking anxiety. How would you apply the findings of the pain perception study by Ibolya, Brake, and Voss (2004) to control for the experimenter's sex as a potential extraneous variable in your design?
Question: Suppose you are designing a new study to measure public speaking anxiety. How would you apply the findings of the pain perception study by Ibolya, Brake, and Voss (2004) to control for the experimenter's sex as a potential extraneous variable in your design?
Sample answer: To control for the experimenter's sex, I would standardize the researcher's biological sex by ensuring all participants are tested by the same experimenter or by experimenters of the same sex. Alternatively, I could balance the design by matching participants to same-sex or opposite-sex experimenters equally across all conditions to ensure the influence of the experimenter's sex does not systematically skew one condition over another.
Key points:
- Propose standardizing the experimenter's sex (e.g., using a single experimenter for all participants).
- Propose balancing the experimenter's sex across experimental conditions.
- Recognize that controlling this variable prevents participant-experimenter dynamics from adding noise or bias to the anxiety scores.
Rubric: The student must apply controls such as standardizing the experimenter's sex (e.g., using only one experimenter or experimenters of one sex) or systematically balancing the experimenter-participant sex pairings across conditions to prevent it from becoming a confounding variable.

Ibolya, Brake, and Voss's Pain Perception Experiment
How can the biological sex of a researcher act as an extraneous variable in a psychological study?
If participants in a psychological experiment respond differently to a task simply because the researcher is female instead of male, the researcher's sex is functioning as an unintended variable that could distort the study's results.
In psychological research, the experimenter's sex can act as an extraneous variable by unintentionally influencing how participants behave. Match each research scenario with the specific way the experimenter's sex is likely impacting the study's data.
A research team is investigating social anxiety but fails to standardize the sex of the experimenters across conditions. Arrange the following steps to analyze how the experimenter's sex functions as an extraneous variable that introduces noise into the study's results.
You are developing a new research protocol to study how competitive pressure influences mathematical problem-solving speed. To ensure that the biological sex of the researcher does not unintentionally influence participant behavior or introduce noise into your data, which of the following novel experimental designs represents the most effective synthesis of controls to 'create' a study environment that neutralizes the experimenter's sex as a potential confounding factor?
In the pain perception study by Ibolya, Brake, and Voss (2004), participants kept their hands immersed in icy water longer when the experimenter was of the same sex.
A researcher critiques a study on pain tolerance because participants persisted significantly longer when interacting with an opposite-sex experimenter. To evaluate the methodological rigor of the study, the researcher identifies that the experimenter's sex functioned as a(n) _____ variable that must be controlled to prevent unintended noise in the findings.
Match each research scenario or concept to its appropriate application regarding researcher characteristics as described in the course content.
In the pain perception study by Ibolya, Brake, and Voss (2004), the researchers analyzed how participant-experimenter dynamics affected pain tolerance. They discovered that participants kept their hands immersed in icy water longer when the experimenter was of the _____, highlighting how researcher sex functions as an extraneous variable.
A research team wants to evaluate and systematically control the experimenter's biological sex as a potential extraneous variable in a new behavioral study. Order the steps they should take from the initial design phase to post-study evaluation.
Describe how the biological sex of a researcher can act as an extraneous variable in a psychological experiment, and recall the specific findings of the pain perception study by Ibolya, Brake, and Voss (2004) that illustrated this effect.
Based on your understanding of researcher characteristics as extraneous variables, explain how the experimenter's biological sex functioned in this study. Describe the underlying mechanism of this phenomenon and explain why it confounds the study's ability to draw clear conclusions about the stress manipulation.
