Mechanisms of Marijuana Reducing Pain

Which of the following best characterizes the explanatory goal of science?

Arrange these research findings in order of the scientific goals they represent, starting with the most basic level of understanding (gathering observations) and ending with the ultimate objective of science (identifying causes).

A researcher finds a strong positive correlation between the amount of sleep students get and their performance on memory tasks. By using this correlation to accurately forecast a student's memory performance based on their sleep habits, the researcher has achieved the explanatory goal of science.

A researcher is investigating why students who participate in study groups tend to perform better on exams. Match each research action or finding to the specific component of the explanatory goal it represents.

In scientific research, the explanatory goal is considered the ultimate objective of science because it goes beyond observation and prediction to determine the precise causes of behavior.

A cognitive psychologist is studying the 'spacing effect'—the phenomenon where learning is superior when study sessions are spaced out over time rather than crammed into a single session. To achieve the explanatory goal of science regarding this phenomenon, which of the following must the psychologist do?

A scientist critiquing a research study that only provides accurate predictions would argue that it has not yet reached the ultimate objective of science because it has failed to isolate the underlying _____ that explain why the behavior occurs.

A developmental psychologist is studying the relationship between childhood play and social skills. Match each of the psychologist's research activities to the specific scientific goal it represents.

A cognitive psychologist finds that a new mnemonic technique reliably forecasts higher exam scores, but they do not know why this occurs. To analyze this phenomenon and achieve the ultimate objective of science, the researcher must move beyond prediction and isolate the underlying _____ that explain the causal relationship.

An evaluator is reviewing a psychologist's research program on pain management. Order the psychologist's research phases from the lowest level of scientific understanding (simple observation) to the highest level of understanding (achieving the ultimate objective of science).

What is the third and ultimate objective of science as described in the research methods literature? In your response, outline the specific tasks researchers must perform to achieve this objective, and explain how it differs from the other goals of science like observation and prediction.

Describe how the psychologist's new research focus on the mechanisms of pain reduction represents a transition to the third and ultimate goal of science. What specific elements must the psychologist identify and isolate to achieve this goal, and why does this go beyond prediction?

Imagine you are designing a new study to investigate the relationship between exam anxiety and test performance. Write a specific research objective that applies the explanatory goal of science to this research topic.
