Document Summary
Biopsychology of emotion, stress, and health. Medial prefrontal lobes emotion and planning. Darwin"s theory of emotional evolution. Emotions evolve from expressions that indicate what an animal is likely to do next. Signals that benefit the animal that expresses them will be enhanced. Principle of antithesis: opposite messages are expressed by opposite movements and postures. Signals of aggression and submission need to be clearly distinguishable in order to be effective. It is the autonomic and somatic signals then that allow the brain to interpret that it is experiencing emotion. Essentially, the body"s reaction to a stimulus causes the interpretation of an emotion. Experience of emotion depends on feedback from ans and somatic ns. Cannon- bard theory: emotional stimuli simultaneously excite bodily feelings (autonomic and somatic) of emotion and cognitive interpretation of an emotion. Experience of emotion is independent of activity in the ans and somatic nervous system. Research has found that emotion does not depend on autonomic or somatic feedback.
