"cannon-bard theory" is a psychological theory of emotion developed by walter cannon and philip bard. this theory states that we feel emotions and experience psychological reactions simultaneously. according to this theory, we react to a stimulus and experience the emotion associated with it at the same time simultaneously. from the above scenario, if i see a wild bear while travelling through the forest, i feel afraid and and i begin to sweat and tremble a lot. this is a good illustration of "cannon-bard theory".
