Quizplus · Accepted Answer

Biological theories of abnormal behavior have primarily implicated dysfunctions in the brain (central nervous system), the peripheral nervous system, or the endocrine system. These dysfunctions can lead to changes in behavior, cognition, and emotion. For example, abnormalities in neurotransmitter levels in the brain have been linked to various mental disorders such as depression, anxiety, and schizophrenia. Hormonal imbalances in the endocrine system have also been associated with certain psychological disorders such as bipolar disorder and eating disorders. The peripheral nervous system, which includes the nerves that control movement and sensation in the body, can also contribute to abnormal behavior when it malfunctions. Therefore, option A is the best choice.
