Researchers investigating the pain-relieving effects of marijuana often look beyond simple correlations to explore whether the drug directly reduces physical inflammation or primarily decreases psychological distress. This approach of seeking causal pathways primarily demonstrates which goal of science?

Researchers investigating marijuana and pain relief move beyond simple observations to explain the relationship. Match each research focus with the scientific concept it best illustrates.

A researcher discovers that marijuana reduces a patient's psychological distress regarding their pain, even though their physical inflammation levels remain unchanged. This finding suggests that the drug is working through a psychological mechanism rather than a physical one.

A researcher is investigating how marijuana reduces pain. Arrange the following research steps in the correct order to illustrate the process of moving from a simple observation to identifying a specific mechanism for the drug's effect.

Researchers seeking to understand how marijuana reduces pain must move through different levels of scientific inquiry. Arrange these research activities in order, starting from the most basic level of inquiry and ending with the level that identifies the specific causal mechanism.

Rather than just noting a correlation, researchers who investigate how marijuana reduces pain look for specific __________ pathways, such as physical inflammation or psychological distress.

To satisfy the explanatory goal of science, a researcher evaluates two competing claims: that marijuana reduces pain by decreasing physical inflammation or by decreasing psychological distress. If empirical evidence reveals significant pain relief without any reduction in physical inflammation, the researcher would conclude that the psychological _____ is the true causal explanation for the drug's effect.

A clinical psychology researcher notes a correlation between medical marijuana use and reduced pain. To achieve the explanatory goal of science, the researcher designs a study. Which of the following approaches best applies this goal?

In a study on marijuana and pain, a researcher who investigates whether pain relief is driven by decreased physical inflammation versus decreased psychological distress is transitioning from the predictive goal of science to the explanatory goal of science.

Match each scientific inquiry goal or action regarding marijuana and pain with the description that best evaluates its role in the scientific process.
