A study that measures participants' self-reported frequency of cannabis use and their scores on a standardized memory test—without assigning anyone to use or abstain from cannabis—is an example of a correlational research design because researchers cannot ethically manipulate the variable of cannabis use.

A researcher wants to study whether cannabis use is related to memory performance. Because it would be unethical to assign people to use cannabis, she instead records how often each participant already uses cannabis and has them complete a standardized memory test. Match each element of this study to its correct description.

A team of researchers wants to study whether long-term cannabis use is associated with differences in memory performance. Since it is unethical to assign participants to use cannabis for a study, which action should the researchers take to investigate this relationship?

A research team wants to investigate whether cannabis use is related to memory. Arrange the steps of the research process in the logical order required to study this topic while adhering to ethical guidelines.

A research team is developing a research blueprint to investigate whether the frequency of cannabis use is statistically related to memory performance. To create an ethically sound study that utilizes a correlational strategy, which of the following methodological frameworks should they synthesize?

To study the relationship between cannabis use and memory, researchers cannot ethically manipulate the independent variable by forcing participants to use cannabis, so they must instead rely on a(n) _____ research strategy, measuring cannabis use frequency and memory performance as they naturally occur.

When evaluating the best method for studying the link between cannabis use and memory, a researcher must prioritize ethical considerations. Because it is unethical to force participants to consume substances, a researcher would justify the use of a(n) _____ strategy to statistically assess the relationship between natural usage levels and test scores.

A researcher wants to study the relationship between alcohol consumption and reaction time, but recognizes that ethically requiring participants to drink set amounts of alcohol is not permissible. Applying the same reasoning used in cannabis-and-memory research, the researcher should record participants' naturally occurring drinking habits alongside their reaction-time scores and then determine whether the two variables are statistically related.

In the cannabis-use-and-memory correlational study, each design element serves a distinct methodological function. Match each element to the specific role it plays in making the study both ethical and scientifically valid.

A research team must first judge whether a correlational design is justified for studying cannabis use and memory, and then carry out that design responsibly. Arrange the following steps in the order that best reflects sound evaluative and methodological reasoning.

According to the provided text about cannabis use and memory, what specific ethical constraint prevents researchers from manipulating the independent variable, and what alternative research strategy must they use instead?

Explain how Dr. Aris's study design demonstrates comprehension of the ethical and methodological principles described in the cannabis and memory example.

Imagine you are tasked with studying the relationship between daily screen time and attention span in children. Applying the correlational research strategy necessitated by ethical and practical constraints, how would you design the measurement of these variables to see if they are related?
