Document Summary

Humans have an innate set of basic emotions that are universally (cross-culturally recognized). Each emotion is a separate (discrete) category--six basic ones--anger, disgust, fear, happiness, sadness, and surprise. Recognizable by facial expression and produced by different biological processes. Conceptualize human emotions by where they lie on 2 dimensions like valence and arousal. A common neurophysiological system is responsible for all emotions, not separate neural processes for each basic emotion. Positive or negative experience that is associated with a particular pattern of physiological activity. Emotions are measured through multidimensional scaling (categorizing by foundational characteristics) Arousal (how positive or negative the event and commensurate emotion is) And valence (physiological arousal instigates emotion: how the emotion is experienced, does the emotion itself fall into positive or negative emotion and what event that is likely to trigger the positive and negative emotion. Stimuli trigger activity in the autonomic nervous system, which in turn produces an emotional experience in the brain.
