Document Summary
Iv: overview: emotions are feeling we all experience at one time or another. The james-lange theory: proposed that we experience emotion in response to physiological changes in our body. Cannon-bard theory: completely opposite from the james-lange theory. He proposed that emotional experience could occur independently of emotional expression. He believed that emotions could be experienced even if physiological change cannot be sensed. He offered cases of animals he and others studied after transection of the spinal cord. Such surgery removed body sensation below the level of the cut, but it did not appear to abolish emotion. He also observed that fear for example is accompanied by increased heart rate, inhibited digestion, and increased sweating. However, these same physiological changes accompany other emotions, such as, anger, illness, etc. Comparison of both theories: in the james-lange theory, the man perceives the threatening animal and reacts. As a consequence of his body"s response to the situation, he becomes afraid.
