What concept refers to a person's feelings and behaviors as responses to their thoughts about events?

Cognitive behavioral therapy (CBT) is the correct choice because it specifically addresses how thoughts influence emotions and behaviors. The fundamental premise of CBT is that cognitive processes (thoughts and beliefs) can significantly affect an individual's emotional state and subsequent actions. For instance, if a person interprets a situation negatively, this may lead to feelings of sadness or anxiety, which can in turn result in avoidance behavior. CBT focuses on identifying, challenging, and changing these negative thought patterns to improve emotional well-being and behavior.

In contrast, behavioral therapy primarily concentrates on modifying specific behaviors without necessarily addressing underlying thought patterns. Affective disorder is a type of mood disorder and does not encompass the cognitive aspects highlighted in the question. Clinical psychology is a broad field that encompasses various therapeutic practices, including CBT, but does not specifically refer to the relationship between thoughts, feelings, and behaviors as its main focus.
