Emily Darnell · Accepted Answer

Final Answer : A, Explanation :  Dr. Abdallah assumes that hormones drive behavior, whereas Dr. Brigham assumes that behavior influences hormone levels. This is because Dr. Abdallah is manipulating hormone levels to observe their effect on behavior, while Dr. Brigham is manipulating behavior to see how it affects hormone levels. Therefore, their assumptions about the causal relationship between hormones and behavior are opposite of each other.
