5. Emotions A. Basic Emotions

Plutchik 8 basic categories but may be just English speaking

B. Theories of Emotion James-Lange theory

Environmental stimuli bring on physiological changes that we interpret as emotions

Cannon-Bard theory Simultaneously processing emotions and bodily responses

Cognitive theory Environment gives us clues that help us interpret stimulus

According to the James-Lange theory, environmental stimuli bring on physiological changes in our bodies and emotions then arise from those physical changes. The Cannon-Bard theory states that the processing of emotions and bodily responses occurs simultaneously rather than one after the other. The cognitive theory of emotion holds that the situation that we are in when we are aroused—the overall environment—gives us clues that help us interpret this general state of arousal. According to recent research, facial expression may influence emotions apart from cognition.

Robert Plutchik's classification system for emotions uses a "circle" to position eight basic categories of emotions that motivate various kinds of adaptive behavior. However, not all cultures view or categorize emotions this way; some do not even have a word for emotion. Others describe feelings by their physical sensations.

6. Communication of Emotion A. Voice Quality B. Facial Expression C. Body Language
