Question: Apply your understanding of research methods to Loftus and Pickrell's false memories study. Describe one concrete adjustment a researcher could make to the design of this study to convert it from an observational design into an experimental design.
Sample answer: To convert the study into an experiment, the researcher could actively manipulate an independent variable by establishing two groups. For example, they could randomly assign one group of participants to receive repeated suggestive questioning about the false mall event (experimental group) and another group to receive no suggestive questioning (control group), then compare the rates of claimed recall between the two groups.
Key points:
- Proposes the active manipulation of an independent variable.
- Establishes distinct comparison groups (e.g., experimental and control).
- Applies these changes specifically to the false memory study paradigm.
Rubric: The answer must propose a concrete modification that introduces an independent variable manipulation and comparison groups (e.g., comparing a group with suggestive questioning to a control group with neutral or no questioning).

In Loftus and Pickrell's false memories study, the researchers repeatedly asked participants about a mildly traumatic childhood event (such as getting lost in a shopping mall) and observed whether participants claimed to remember it, without actively manipulating an independent variable to compare groups.
In the Loftus and Pickrell 'lost in the mall' study, researchers repeatedly asked participants about a childhood event that never actually occurred and recorded their responses over time. Why is this specific study classified as an example of observational research?
In the 'lost in the mall' study, Loftus and Pickrell observed how false memories form without using an experimental manipulation. Match each research action from this study to the role it plays in an observational design.
Analyze the methodology of the Loftus and Pickrell 'lost in the mall' study. Arrange the following steps in the logical order required to explain why this research is classified as an observational design rather than an experiment.
In Loftus and Pickrell's false memories study, what did the researchers observe to examine memory formation without actively manipulating an independent variable?
The Loftus and Pickrell 'lost in the mall' false memory study is categorized as an experimental design because researchers actively compared a group of participants who had actually experienced the event to a control group who had not.
If a researcher were evaluating the Loftus and Pickrell 'lost in the mall' study to determine if it provides definitive evidence of causality, they would conclude it does not because the methodology lacks the active _____ of an independent variable.
Apply your understanding of research design by matching each methodological feature of the Loftus and Pickrell false memories study to the design criterion it addresses.
When analyzing the Loftus and Pickrell false memory study, a researcher notes that all participants received the same repeated questioning procedure. Because no _____ group was included—that is, participants who were never asked about the shopping mall event—the study cannot rule out alternative explanations for why participants reported the memory.
A student is evaluating whether the Loftus and Pickrell false memories study would have produced stronger causal evidence if it had been redesigned as a true experiment. Arrange the following evaluative steps in the most logical order for conducting this critique.
Recall the details of Loftus and Pickrell's false memories study as described in the course material. Explain what specific behavior the researchers observed, and state the methodological reason why this study is classified as observational research.
Based on your comprehension of Loftus and Pickrell's false memories study, diagnose the error in the student's classification of her research design. Explain why this study is observational rather than experimental, detailing what key element of a true experiment is missing.
