Question

Quizplus · Accepted Answer

The study found that the psychological history of the individual, specifically whether they were raised with a sense of control or not, influenced how they responded to an anxiety-inducing drug. This suggests that neurotransmitters, which are influenced by psychological factors, can have different effects on behavior depending on an individual's psychological history. Therefore, choice B is the best answer.
