Document Summary
Psy1022 - week 21: the nature of emotion. The subjective experience of emotion has several characteristics. Psy1022 - week 22: emotion is usually temporary; it tends to have a relatively clear beginning and end, as well as a relatively short duration. Moods, by contrast, tend to last longer: emotional experience can be positive, as in joy, or negative, as in sadness. The objective aspects of emotion include learned and innate expressive displays and physiological responses. Physiological responses such as changes in heart rate are the biological adjustments needed to perform the action tendencies generated by emotional experience. Emotions are transitory positive or negative experiences that are felt as happening to the self, are generated in part by cognitive appraisal of a situation, and are accompanied by both learned and innate physical responses. Emotions are processed in the limbic system, through facial expressions, and involving the cerebral cortex. Activity in the limbic system, especially in the amygdala, is central to emotion.
