Final answer:
The cognitive approach to personality indicates that negative thoughts can influence both emotions and behavior, as specified in Bandura's social-cognitive theory and the concept of cognitive dissonance.
Step-by-step explanation:
The cognitive approach to personality suggests that negative thoughts can influence both emotions and behavior. Therefore, the correct answer to the question is B) Influence emotions and behavior. This approach is based on the idea that our cognitive processes, such as attitudes, thoughts, and beliefs, are not only influenced by external forces but also by internal influences that we control. According to the social-cognitive theory, proposed by Albert Bandura, there is a reciprocal determinism where cognitive processes, behavior, and context interact and influence each other. This includes our beliefs and expectations which can affect our behavior and emotions. Furthermore, the concept of cognitive dissonance also shows how an imbalance between these components can lead to changes in attitudes or behaviors to reduce tension.
