The video explores the concept of emotions in animals and humans, discussing their evolutionary purpose and the role they play in survival. It covers various theories of emotion, including the James-Lange and Cannon-Bard theories, and examines the limbic system's involvement in emotional expression. The video also delves into the study of fear and aggression, highlighting their significance in animal behavior. Additionally, it discusses the neuroscience of emotion, emphasizing the brain's role in emotional experiences. Finally, the video addresses the stress response, explaining its physiological effects and impact on health.

How can chronic stress affect the immune system?

• It improves innate immune function

• It adversely affects adaptive immune function

• It has no effect on immune function

• It enhances adaptive immune function

What is the two-system view of the stress response?

• A framework for understanding social interactions

• A theory that focuses on cognitive appraisal

• A model that includes the HPA axis and the sympathetic nervous system

• A concept that explains emotional regulation

What is a common psychological stressor that can trigger an HPA axis response?
