Based on the study by Halle Brown and colleagues (1999) described in the source, identify the two independent variables investigated and describe their nature (which one was manipulated and which was measured as a pre-existing participant variable). Then, recall the specific pattern of recall findings for individuals high versus low in hypochondriasis across the different word types.
Question: Based on the study by Halle Brown and colleagues (1999) described in the source, identify the two independent variables investigated and describe their nature (which one was manipulated and which was measured as a pre-existing participant variable). Then, recall the specific pattern of recall findings for individuals high versus low in hypochondriasis across the different word types.
Sample answer: In the study by Brown and colleagues (1999), the two independent variables were: 1) the type of word presented, which was a manipulated independent variable consisting of negative health-related words (e.g., 'tumor', 'coronary') and non-health-related words (e.g., 'election', 'geometry'); and 2) the level of hypochondriasis, which was a non-manipulated (measured) participant variable representing whether participants had high or low levels of pre-existing concern with bodily symptoms. The findings showed that participants high in hypochondriasis recalled more health-related words than those low in hypochondriasis, but there was no difference in recall performance between the two groups for the non-health-related words.
Key points:
- Identifies the type of word as the manipulated independent variable.
- Identifies the participant's level of hypochondriasis as the non-manipulated (measured) independent variable.
- Recalls that high-hypochondriasis participants recalled more health-related words than low-hypochondriasis participants.
- Recalls that there was no recall difference between high- and low-hypochondriasis participants for non-health-related words.
Rubric: The answer should be evaluated on the correct identification of the two independent variables (word type and hypochondriasis level), their correct categorization as manipulated vs. measured/non-manipulated, and the accurate recall of the interaction results (high-hypochondriasis participants recalled more health-related words but showed no difference on non-health-related words).

A study investigated memory biases by presenting participants with health-related and non-health-related words while measuring their pre-existing levels of hypochondriasis. In this scenario, what served as the non-manipulated independent variable?
In a study examining memory biases, researchers measured participants' pre-existing levels of hypochondriasis and then assigned them to view either health-related or neutral words. Match each component of this study to its correct classification based on how it is used in the research design.
In a study investigating memory biases, if a researcher uses a medical documentary to induce health anxiety in participants instead of measuring their pre-existing levels of hypochondriasis, the independent variable is classified as manipulated.
A researcher is conducting a study to analyze how pre-existing hypochondriasis levels influence memory for different word types. Arrange the following steps in the correct logical order to reflect the design process used to identify the interaction between the measured participant characteristic and the experimental manipulation.
You are proposing a new research study to determine if the selective memory bias observed in individuals with hypochondriasis can be eliminated by using a 'cognitive distraction' task. You plan to present health-related and neutral words to participants while they either perform a secondary task or do nothing. To properly structure this study using hypochondriasis as a non-manipulated independent variable, which of the following experimental frameworks must you implement?
In the study investigating memory biases, individuals high in hypochondriasis were found to selectively recall more health-related words than non-health-related words.
In a study investigating memory biases, researchers measured participants' pre-existing levels of hypochondriasis and found that those with high levels recalled more health-related words. When evaluating the internal validity of this design, a researcher would conclude that a definitive causal claim cannot be made because hypochondriasis is a(n) _____ independent variable.
A researcher is designing a factorial study modeled on the hypochondriasis memory experiment. Match each proposed design element to its correct methodological label.
In the hypochondriasis memory study, high-hypochondriasis participants outperformed low-hypochondriasis participants on health-related words but showed no advantage on non-health-related words. Because the effect of word type depended on participants' hypochondriasis level, this pattern is best described as a(n) _____ between the two independent variables.
A fellow student proposes a study using a non-manipulated independent variable similar to the hypochondriasis memory experiment and claims the design supports a causal conclusion. Arrange the following steps in the correct logical order for critically evaluating whether their design justifies that claim.
Based on the study by Halle Brown and colleagues (1999) described in the source, identify the two independent variables investigated and describe their nature (which one was manipulated and which was measured as a pre-existing participant variable). Then, recall the specific pattern of recall findings for individuals high versus low in hypochondriasis across the different word types.
Explain why hypochondriasis is considered a non-manipulated independent variable in this study rather than a manipulated one. Furthermore, explain how this classification limits the researcher's ability to conclude that hypochondriasis causally determines the observed difference in memory recall.
If a researcher presents a list of words containing 'coronary' (health-related) and 'election' (non-health-related) to two individuals—one scoring very low on a hypochondriasis scale and one scoring very high—apply the findings of Brown and colleagues (1999) to predict their relative recall performance on both word types.
