Although bodily perception theories of emotion have become popular in recent years, they fail to
account for the full range of emotional phenomena. There are only weak correlations between
emotions such as anger and fear and physiological states such as facial behavior and autonomic
arousal. The subtle differences between diverse emotions have not been found to be closely related to
distinct physiological states, their magnitudes, or particular neurotransmitters. Surgical disruption of
bodily signals does not eliminate emotional reactions. Manipulations of physiology by injection of
epinephrine can produce different emotional reactions depending on how people interpret their social
situations. Social emotions such as guilt and pride require an appreciation of one's location in a
social network. Hence cognitive appraisal is needed to complement bodily perception to generate a
full range of emotional reactions. However, bodily perception remains a crucial part of the
EMOCON model, which assumes that appraisal alone would not produce the kinds of feelings that
occur in emotional consciousness.
