Based on the study by Schnall and colleagues on disgust and moral judgments, describe the initial main effect found by the researchers, the interacting variable that qualified this main effect, and how simple effects analyses were used to clarify the interaction.
Question: Based on the study by Schnall and colleagues on disgust and moral judgments, describe the initial main effect found by the researchers, the interacting variable that qualified this main effect, and how simple effects analyses were used to clarify the interaction.
Sample answer: Initially, a main effect indicated that participants in a messy room made harsher moral judgments due to disgust. However, an interaction showed that this effect depended on the participant's level of private body consciousness. By using simple effects analyses to examine the effect of disgust at each level of private body consciousness, the researchers demonstrated that disgust increased the harshness of moral judgments only for individuals high in private body consciousness, while it had no effect on those low in private body consciousness.
Key points:
- Recall that the initial main effect showed disgust (messy room) led to harsher moral judgments.
- Identify private body consciousness as the moderator/interacting variable that qualified the main effect.
- Recall that simple effects analyses looked at the effect of disgust at each level of private body consciousness.
- State that disgust increased harsh moral judgments only for individuals high in private body consciousness.
- State that disgust had no effect on moral judgments for individuals low in private body consciousness.
Rubric: The answer must recall: 1) the initial main effect (messy room/disgust leading to harsher moral judgments); 2) the interacting/moderating variable (private body consciousness); and 3) the specific findings of the simple effects analyses (disgust increased harsh judgments only for high private body consciousness, but had no effect for low private body consciousness).

In the study by Schnall and colleagues, what did the simple effects analyses reveal about how disgust influenced moral judgments?
In a study on disgust and moral judgments, an initial main effect suggested that being in a messy room led all participants to make harsher moral judgments. However, after examining the interaction with private body consciousness, this main effect turned out to be an accurate summary of the pattern for all participants.
In the study by Schnall and colleagues, researchers investigated how environmental disgust (a messy room) influences moral judgments, moderated by 'private body consciousness' (PBC). Match each statistical component with the specific finding it describes from this research.
A researcher is investigating how environmental disgust (a messy room) affects the harshness of moral judgments, while considering private body consciousness (PBC) as a potential moderator. Arrange the steps of the statistical reasoning process used to clarify how an interaction can render a main effect misleading.
You are constructing a research proposal to replicate the study by Schnall and colleagues regarding disgust and moral judgments. Which of the following research designs and predicted outcome patterns correctly models the interaction such that simple effects analyses are required to clarify a potentially misleading main effect?
In the study by Schnall and colleagues, simple effects analyses revealed that environmental disgust increased the harshness of moral judgments only for individuals low in private body consciousness.
In their study on disgust and moral judgments, Schnall and colleagues demonstrated how an interaction can make a main effect misleading. Match each statistical or conceptual element of their study with its correct interpretation or significance in the overall findings.
In the study by Schnall and colleagues (2008), a conclusion that environmental disgust universally causes people to make harsher moral judgments would be evaluated as _____ because an interaction analysis revealed that the effect was only present for individuals with high private body consciousness and was absent for those with low levels.
In the Schnall et al. study on disgust and moral judgments, the finding that disgust increased harsh judgments only for individuals high in private body consciousness—and had no effect on those low in private body consciousness—indicates that private body consciousness functioned as a _____ variable, because it determined whether the disgust effect was present or absent.
You are peer-reviewing a manuscript that reports findings structured like those of Schnall et al. Arrange the following evaluative judgments in the logical order a critical reviewer would apply them to decide whether the authors' conclusion about disgust and moral judgments is adequately justified.
Based on the study by Schnall and colleagues on disgust and moral judgments, describe the initial main effect found by the researchers, the interacting variable that qualified this main effect, and how simple effects analyses were used to clarify the interaction.
Diagnose why the student's planned conclusion is misleading based on the concepts of main effects and interactions. Comprehending how interactions qualify main effects as shown in the Schnall et al. study, describe what statistical analysis the student should perform to resolve this and what the analysis would reveal.
Apply the logic of simple effects analyses from the Schnall et al. study to a new scenario: If you are investigating how a new teaching method (vs. traditional method) affects test scores, and you find a significant interaction with students' motivation level (high vs. low), what are the two specific simple effects comparisons you would need to calculate to unpack this interaction?
