Imagine you are a psychology researcher interested in studying the relationship between early childhood illness experiences and the development of hypochondriasis in adulthood. Explain how you would design this study using a non-experimental approach and explain why an experimental approach cannot be used in this situation.
Question: Imagine you are a psychology researcher interested in studying the relationship between early childhood illness experiences and the development of hypochondriasis in adulthood. Explain how you would design this study using a non-experimental approach and explain why an experimental approach cannot be used in this situation.
Sample answer: To study this relationship using a non-experimental approach, I would measure the variables as they naturally occur without manipulating them. I could use survey methods to ask adults to self-report their current levels of hypochondriasis and their history of childhood illnesses to describe the relationship between these two variables. An experimental approach cannot be used here because it is ethically and practically impossible to manipulate the independent variable; a researcher cannot intentionally cause children to experience early illnesses just to observe if it causes hypochondriasis later in life. Therefore, a non-experimental design is necessary, even though it means I cannot draw a definitive causal conclusion.
Key points:
- Measure variables as they naturally occur without manipulation.
- Acknowledge the ethical or practical impossibility of manipulating the independent variable (childhood illness).
- State that experimental research cannot be carried out in this scenario.
- Recognize that while relationships can be described and predicted, causal conclusions cannot be drawn.
Rubric: The response must correctly identify that variables are measured as they naturally occur rather than manipulated. It must explain the ethical or practical impossibility of manipulating childhood illness, demonstrating why non-experimental research is required. It should also acknowledge the limitation regarding causal conclusions.

What is the defining characteristic of non-experimental research?
A study that measures the naturally occurring levels of social media use and self-esteem in a group of high school students to see how they are related is an example of non-experimental research.
Match the core characteristics of non-experimental research with the descriptions that best explain their role in a psychological study.
A researcher conducts a study on the relationship between students' natural sleep patterns and their academic performance by tracking them for a semester. Arrange the following steps in the logical order required to analyze this methodology and determine its scientific boundaries.
A researcher is tasked with designing a study to investigate how the frequency of naturally occurring social interactions in the workplace relates to the overall job satisfaction of employees. Since the researcher cannot ethically or practically assign employees to have more or fewer friends at work, which of the following research plans best constructs a valid non-experimental design for this investigation?
A psychologist is evaluating the most ethical way to study how surviving a natural disaster affects long-term personality. Because the researcher cannot ethically expose participants to such trauma, they must conclude that the most appropriate methodology is _____, even though this design cannot provide definitive evidence that the disaster caused the personality changes.
Non-experimental research methodologies are characterized by the lack of _____ of an independent variable.
Imagine you are a psychology researcher interested in studying the relationship between early childhood illness experiences and the development of hypochondriasis in adulthood. Explain how you would design this study using a non-experimental approach and explain why an experimental approach cannot be used in this situation.
Based on the principles of non-experimental research, analyze Dr. Smith's conclusion. What specific type of non-experimental research did she conduct, what defines it as non-experimental, and why is her press conference statement problematic?
A fellow psychology student argues that because non-experimental research cannot provide strong evidence that changes in an independent variable cause differences in a dependent variable, it is nonscientific and less important than experimental research. Evaluate this claim based on the goals of science and the practical constraints of psychological research.
Which of the following best explains why researchers generally cannot draw causal conclusions from non-experimental research?
A psychology student is reviewing different research proposals. Apply your understanding of experimental versus non-experimental research to match each proposed research question with the correct methodology and rationale.
A psychologist tightly controls the temperature, lighting, and noise levels of a laboratory while observing the natural association between adults' baseline stress levels and their memory recall. Because the researcher successfully controlled these environmental factors, this methodology is classified as an experimental design rather than non-experimental research.
