Document Summary

Emoion: response of whole organism, involving physiological arousal and expressive behaviours and conscious experience. James-lange theory: theory that our experience of emoion is our awareness of physiological response to emoion arousing simuli, emoion is separate from body arousal. Arguments: implausible, body"s response not disinct enough to evoke diferent emoions (racing heart signals love, fear, etc. : disinct physiological response, experienced emoion. Cannon-bard theory: theory that an emoion arousing simulus simultaneously triggers physiological responses and subjecive experience emoion. Two-factory theory: the schachter-singer theory that to experience emoion one must be physically aroused and cogniively label the arousal, Polygraph: machine, common in atempts to detect lies, measures physiological responses accompanying emoions, eg. perspiraion, cardiovascular and breathing changes. Shortcut for emoions: sensory input may be rooted directly to amygdala via thalamus for an instant emoional reacion or to cortex for analysis. Zajonc and ledoux: emphasized that some emoional responses are immediate before conscious appraisal (thinking), automaic.
