Based on the provided details of the expressive writing experiment, identify the two main categories of extraneous variables that researchers must manage, and list the specific examples of variables given for each category.
Question: Based on the provided details of the expressive writing experiment, identify the two main categories of extraneous variables that researchers must manage, and list the specific examples of variables given for each category.
Sample answer: The two main categories of extraneous variables are participant variables (individual differences) and situational/task variables. Participant variables include baseline writing ability, gender, and diet. Situational and task variables include the weather, the time of day, and whether participants type or write by hand.
Key points:
- Identify participant variables as one of the categories of extraneous variables.
- Identify situational/task variables as the other category of extraneous variables.
- List baseline writing ability, gender, and diet as participant variables.
- List weather, time of day, and typing versus writing by hand as situational/task variables.
Rubric: To receive full credit, the student must: 1) Identify 'participant variables' (or individual differences) and 'situational and task variables' as the two categories. 2) List baseline writing ability, gender, and diet as examples of participant variables. 3) List weather, time of day, and writing medium (typing vs. writing by hand) as examples of situational/task variables.

In an expressive writing experiment, researchers must manage multiple outside factors. Match each example of an extraneous variable with its corresponding category.
In an experiment investigating the impact of expressive writing on physical health, researchers often require all participants to use the same medium (such as typing on a laptop) rather than letting some handwrite and others type. What is the primary reason for this control?
In an experiment testing whether expressive writing improves physical health, a researcher requires every participant to complete their writing task in the same quiet laboratory at 10:00 AM. By standardizing the environment and timing, the researcher is holding a(n) ________ variable constant.
In an expressive writing experiment, a researcher who standardizes the writing medium (e.g., typing) and the session time (e.g., 10:00 AM) has controlled for task and situational variables, respectively, but still faces potential unintended variability from participant variables such as 'diet' or 'baseline writing ability'.
A researcher is evaluating the internal validity of an experiment on expressive writing and physical health. Arrange the following steps in the logical order they would use to judge whether the results were truly caused by the writing task rather than extraneous variables.
According to the description of the expressive writing experiment, which of the following is an example of a participant variable that researchers must manage?
In the expressive writing experiment, if researchers fail to manage extraneous variables like a participant's diet, they cannot be certain whether physical health improvements were caused by the writing or by the diet itself.
In the expressive writing experiment, researchers implement specific controls to address different extraneous variables. Match each researcher action to the specific extraneous variable it is designed to control.
A researcher analyzing the expressive writing study categorizes its extraneous variables by their source. She observes that time of day, weather, and the physical location of sessions all arise from the circumstances under which the study is conducted — not from individual differences among participants and not from the nature of the writing task itself. On the basis of this analysis, she classifies all three as _____ variables.
A peer reviewer is evaluating a published expressive writing and health study to judge whether the researchers' handling of extraneous variables justifies their causal conclusion. Arrange the following steps in the order the reviewer should complete them.
Based on the provided details of the expressive writing experiment, identify the two main categories of extraneous variables that researchers must manage, and list the specific examples of variables given for each category.
Explain why these unmanaged participant, situational, and task variables threaten the validity of the study's conclusions, and explain what researchers must do to resolve this issue.
A researcher planning the expressive writing experiment wants to ensure that situational and task variables do not introduce unintended variability. Describe how the researcher can apply the concept of 'holding factors constant' specifically for the time of day and the writing medium.
