Chapter 12 – Emotion, Stress, And Health Any stimulus that arouses emotion alters the activity of the autonomic nervous system the section of the nervous system that controls the organs such as the heart and intestines The autonomic nervous system has two branches - Two chains of neuron clusters just to the left and right of the spinal cord comprise the sympathetic nervous system which arouses the body for vigorous action (often called the “fight-or-flight” system because it increases your heart rate, breathing rate, sweating, and flow of epinephrine) - The parasympathetic nervous system consists of neurons whose axons extend from the medulla and the lower part of the spinal cord to neuron clusters near the organs ; decreases the heart rate and promotes digestion and other non-emergency functions The Theories of Emotion : - James-Lange Theory: your interpretation of a stimulus evokes autonomic changes and sometimes muscle action; your perception of those changes is the feeling aspect of your emotion . e.g.: the situation (the sight of a bear) gives rise to an action (running away), and your perception of that action is the emotion. (you don’t run away because you’re afraid, you feel afraid because you perceive yourself running away) - Schacter and Singer’s Theory : the intensity of the physiological state – that is, the degree of sympathetic nervous arousal – determines the intensity of the emotion, but a cognitive appraisal of the situation identifies the type of emotion. If someone has a spinal cord injury they have no decrease in emotions. Someone with a spinal cord injury will report normal or nearly normal emotions Fear vs. Anxiety (fear generally refers to the response to an immediate danger, whereas anxiety is vague, long-lasting sense that “something bad might happen”) Anxiety : an increase in the startle reflex ; the startle reflex is the quick, automatic response that almost any animal makes after a sudden loud noise. - The amygdala is the key brain area for learning fears and anxiety. - The response is stronger depending on the context: loud noise while sitting on the beach with friends vs. loud noise while walking alone through a graveyard at night - The startle response is stronger in people with anxiety issues - Polygraph (lie-detector test): indications of sympathetic nervous system arousal, and electrical conduction of the skin. Sometimes elicits confession, otherwise unreliable - Alternative – Guilty-knowledge test : a modified version of the polygraph test, produces more accurate results by asking questions that should be threatening only to someone who knows the facts of a crime that have not been publicized - A coping method for anxiety is doing something that you enjoy and are familiar with. also listening to music works
