What does research by Johnson and colleagues (2000) on cigarette smoking by teenagers and anxiety disorders suggest?

Question

Quizplus · Accepted Answer

Johnson and colleagues' research suggests a possible link between cigarette smoking by teenagers and anxiety disorders, indicating that environmental factors such as smoking can affect the sensitivity of brain circuits. This implies that the brain is not permanently "wired," and that neurotransmitter systems are influenced by external factors. Respiratory disorders are not mentioned in the research. Lastly, the assertion that neurotransmitter systems operate entirely independently of nonbiological influences is not supported by the findings of the research.
