A researcher wants to determine whether hippocampus damage impairs the formation of long-term memories. After reviewing ethical guidelines, she concludes that because random assignment to a 'hippocampus-damage' condition is impossible, no rigorous scientific investigation of this question can be conducted, and she abandons the study entirely.

Why must researchers studying the effects of hippocampus damage on long-term memory rely on non-experimental methods?
To understand why researchers must use non-experimental methods to study hippocampus damage, match each research component with its corresponding role or definition in this specific ethical scenario.
Dr. Aris is planning a study to investigate if the hippocampus is essential for spatial memory. According to ethical standards in psychology research, Dr. Aris should utilize a non-experimental design that recruits individuals with pre-existing hippocampus damage rather than attempting to intentionally cause lesions in healthy volunteers.
A researcher wants to investigate whether the hippocampus is necessary for the formation of long-term memory. Arrange the steps of the research process in the correct logical order, accounting for the ethical and practical constraints inherent in studying brain damage.
In the example of hippocampus research, what specific action is a researcher unable to perform on the independent variable due to ethical and practical constraints?
Researchers investigating the role of the hippocampus in memory must use non-experimental methods because they cannot ethically or practically _____ the independent variable of brain damage.
When evaluating research designs for studying whether hippocampus damage impairs long-term memory formation, a researcher must reject a true experiment as unacceptable because intentionally inflicting brain damage on participants would violate _____ standards of psychological research.
A researcher wants to determine whether hippocampus damage impairs the formation of long-term memories. After reviewing ethical guidelines, she concludes that because random assignment to a 'hippocampus-damage' condition is impossible, no rigorous scientific investigation of this question can be conducted, and she abandons the study entirely.
The hippocampus damage example illustrates why certain studies cannot be conducted as true experiments. Match each research element to the distinct role it plays in explaining this constraint.
A research team wants to justify their choice of a non-experimental design to study hippocampus damage and long-term memory formation. Place the following evaluative steps in the order that best demonstrates a principled, well-reasoned design decision.
Recall and describe the specific practical and ethical constraints that prevent researchers from conducting a true experiment to determine whether damage to the hippocampus impairs long-term memory formation. How do researchers overcome these constraints?
Explain why Dr. Smith's research question prevents him from using a true experimental design. In your explanation, identify what design approach he must adopt instead and how this alternative design addresses the ethical challenges of studying brain damage.
Suppose you are designing a study to test whether a new cognitive training exercise can help patients with hippocampus damage form long-term memories. Apply the ethical and practical principles of non-experimental research to explain how you would select your participant sample.
