Based on the study by Schnall and colleagues, identify which variable was manipulated and which was only measured. Then, explain why the researchers could not make a causal claim about the relationship between the measured variable and moral judgments, specifically recalling the potential third variable they suggested.
Question: Based on the study by Schnall and colleagues, identify which variable was manipulated and which was only measured. Then, explain why the researchers could not make a causal claim about the relationship between the measured variable and moral judgments, specifically recalling the potential third variable they suggested.
Sample answer: In the study, disgust was the manipulated variable, while private body consciousness was only measured. The researchers could not make a causal claim about private body consciousness because it was not manipulated, meaning any association could be due to an unmeasured third variable, such as neuroticism, which independently increases both bodily awareness and moral strictness.
Key points:
- Disgust was the manipulated variable.
- Private body consciousness was the measured variable.
- Causal claims are limited because private body consciousness was not manipulated.
- An association could be due to an unmeasured third variable.
- Neuroticism is the specific third variable that could increase both bodily awareness and moral strictness.
Rubric: The answer must correctly identify disgust as manipulated and private body consciousness as measured. It must recall that no causal claim can be made for private body consciousness because it was not manipulated, and specify neuroticism as the potential unmeasured third variable that independently increases both bodily awareness and moral strictness.

In a study on disgust and moral judgments, researchers manipulated feelings of disgust and also measured participants' level of private body consciousness (awareness of internal bodily sensations). Why were the researchers unable to make a causal claim about private body consciousness and moral judgments?
In Schnall and colleagues' study on disgust and morality, researchers found that different research components provided different levels of evidence for causality. Match each component of the study with the statement that best describes its role or limitation in establishing a causal claim about moral judgments.
Researchers found that while manipulated disgust levels influenced moral judgments, the association between measured private body consciousness and those same judgments could not be claimed as causal. Arrange the steps of the logical analysis that leads to the conclusion that this relationship is limited by a third-variable problem.
A researcher argues that the study by Schnall and colleagues provides sufficient evidence to conclude that private body consciousness causes harsher moral judgments because the researchers found a significant association between the two. This researcher's evaluation of the study's causal evidence is scientifically sound.
In the study by Schnall and colleagues, the researchers were able to rule out the third-variable problem for private body consciousness because they statistically controlled for all potentially confounding personality traits like neuroticism.
A researcher finds that individuals who score high on a 'private body consciousness' scale also tend to make harsher moral judgments. According to the causal logic illustrated by Schnall and colleagues, the researcher cannot conclude that body awareness causes these judgments because the relationship might be driven by a(n) _____ variable, such as neuroticism.
In the study by Schnall and colleagues, the researchers suggested that the correlation between private body consciousness and moral strictness might be caused by an unmeasured third variable such as _____.
A researcher measures participants' daily screen time and assesses their sleep quality using a questionnaire. They find a statistically significant association: higher screen time predicts poorer sleep quality. Applying the causal logic illustrated by Schnall and colleagues' study on disgust and moral judgments, which conclusion is BEST supported by this finding?
In Schnall and colleagues' study on disgust and moral judgments, several distinct methodological features each carry specific implications for causal inference. Match each feature to the conclusion it supports or the limitation it creates.
A student reads the Schnall et al. study and wants to evaluate whether the claim 'private body consciousness causes harsher moral judgments' is scientifically justified. Arrange the following evaluation steps in the order that produces the most logically rigorous assessment, from first to last.
Based on the study by Schnall and colleagues, identify which variable was manipulated and which was only measured. Then, explain why the researchers could not make a causal claim about the relationship between the measured variable and moral judgments, specifically recalling the potential third variable they suggested.
Evaluate the student's causal claims. Based on the logic of research design and causal limitations discussed in the text, explain why the claim regarding disgust is justified while the claim regarding private body consciousness is not, and describe how an unmeasured third variable could explain the latter finding.
A researcher finds a correlation between participants' measured level of self-reflection and their strictness on moral judgments, and concludes that self-reflection causes moral strictness. Apply the causal limitation principles from the Schnall et al. study to write a brief two-sentence critique of this conclusion and state what must be done to the variable to establish causality.
