EMOTION An emotion involves a response of the whole organism, and has three important components: 1. Physiological Arousal ( e.g., heart pounding, sweating ) 2. Expressive Behaviors ( e.g., widened eyes, quickened pace ) 3. Conscious Experience: thoughts ( e.g., is that a bear? ) and feelings ( e.g., fear )

THREE MAJOR THEORIES OF EMOTION 1. The James - Lange Theory 1842 - 1910 William James “Common sense says, we lose our fortune, are sorry and weep; we meet a bear, are frightened and run; we are insulted by a rival, are angry and strike. The hypothesis here to be defended says that this order of sequence is incorrect ... and that the more rational statement is that we feel sorry because we cry, angry because we strike, afraid because we tremble ... Without the bodily states following on the perception, the latter would be purely cognitive in form, pale, colorless, destitute of emotional warmth. We might then see the bear, and judge it best to run, receive the insult and deem it right to strike, but we should not actually feel afraid or angry.”

THREE MAJOR THEORIES OF EMOTION 1. The James - Lange Theory 1834 - 1900 Carl Lange “Take away the bodily symptoms from a frightened individual; let his pulse beat calmly, his look be firm, his color normal, his movements quick and sure, his speech strong and his thoughts clear; and what remains of his fear?”

THREE MAJOR THEORIES OF EMOTION 1. The James - Lange Theory The theory that emotion arises from an awareness of our physiological responses to emotion - arousing stimuli. Physiological activity precedes the emotional experience: We experience the emotion when we become aware of a distinct pattern of physiological arousal! Each emotion is associated with a particular pattern of physiological arousal.

THREE MAJOR THEORIES OF EMOTION 2. The Cannon - Bard Theory 1871 - 1945 Walter Cannon There are five reasons why the James - Lange theory is wrong: 1. Total separation of the viscera from the central nervous system does not alter emotional behavior ( e.g., sympathectomized cat still expresses aggression in front of dog ) 2. The same visceral changes occur in very di ff erent emotional states and in non - emotional states ( e.g., cry when happy and sad ) 3. The viscera are relatively insensitive structures ( e.g., blood pressure may change but unaware of it ) 4. Visceral changes are too slow to be a source of emotional feeling ( e.g., we feel sad before we cry ) 5. Artificial induction of the visceral changes typical of strong emotions does not produce them ( e.g., after a sprint you don’t feel angry/happy/ sad even though heart rate, blood pressure, breathing rate are elevated )

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
