How the Cannon

For example, imagine that you are walking to your car through a darkened parking garage. Cats were decorticated, and after a period of recovery they spontaneously displayed the behaviours characteristic of intense fury. This is the first beautiful day in a week after some crummy weather, keeping her and the child in the house for far too long. According to the James-Lange theory, you then interpret your physical reactions to the stimulus as fear. Furthermore, after cerebral hemispheres were removed from animal test subjects, correct affective responses could be elicited by appropriate stimulations. The bodily changes and emotional experience occur separately and independently of one another; physiological arousal does not have to precede emotional expression or experience.

In order to experience an emotion, we must first have a bodily response, and then we experience the emotion. This was necessary because the link between visceral changes and the feedback required to stimulate cerebral manifestations of an emotion would no longer be present. All participants had to complete a questionnaire while holding the pen and rate the difficulty of doing so. This outcome supported the facial feedback hypothesis. Cannon identified and outlined five issues with the James—Lange theory's notion of the vasomotor center as the explanation of emotional experience.

What Is the Cannon

Cannon articulated that these responses of the are too uniform to offer a means of distinguishing emotions that have varying subjective qualities. According to the Cannon-Bard theory of emotion, you will experience feelings of fear and physical reaction at the same time. For example, in the case of the viscera, we are unaware of the contractions and relaxations of the digestive processes. As predicted, participants in the Teeth condition who were, technically, smiling throughout the exercise reported significantly higher amusement ratings than those in the Lips condition. James-Lange theory would then suggest that you would label those feelings as fear.

Cannon pointed out that the time required for nerve impulses to travel from the brain to the periphery and back to the brain again could not occur quickly enough to be the cause of such emotional responses. Researchers have developed several theories of how human emotions arise and are represented in the brain. In this research, it was argued that emotional expression must be independent of the cortex because the expression of emotions cannot always be inhibited or controlled e. In one interesting field study by Dutton and Aron 1974 , an attractive young woman approached individual young men as they crossed a wobbly, long suspension walkway hanging more than 200 feet above a river in British Columbia, Canada. You notice a dark figure trailing behind you and your heart begins to race. Therefore, if these visceral changes were artificially induced by the injection of , one would expect the emotions to follow, as articulated by the James—Lange theory of emotion.

Psychologists have proposed three different theories of emotion, which differ in terms of the hypothesized role of arousal in emotion. Both James and Lange did present some clinical findings to support their theory. It has been found that the latent period of the psychogalvanic response in man is approximately 3 seconds. This then leads to the feelings of fear and the physical reactions that follow. One day they are madly in love with each other and the next they are in a huge fight. While the James—Lange theory proposes that emotions arise from physical arousal the Cannon—Bard theory argues that physiological arousal and emotional experience occur simultaneously, yet independently Lang, 1994.

Patients who have spinal injuries that reduce their experience of arousal also report decreases in emotional responses Hohmann, 1966. The physiological changes and subjective feeling of an emotion in response to a stimulus are separate and independent; arousal does not have to occur before the emotion Adcock, 1976. According to the James-Lange theory of emotion, our ex p e ri e n c e of an e motion is the r e sult of the arousal that w e ex p e ri e n c e. They agree with James-Lange that people infer emotions when they experience physiological arousal but also agree with Cannon-Bard that the same pattern of physiological arousal can give rise to different emotions. Today, many researchers would instead suggest that rather than our emotions being the result of physical reactions as James and Lange suggested, our emotional experiences are instead modified by both physiological reactions along with other information.

According to Arnold, an initial appraisal begins the emotional sequence by arousing both the appropriate physiological reactions and the emotional experience itself. First, after the removal of the to the thalamus in animal test subjects, the animals continue to display rage-like emotional responses. Before long, the mother hears her child cry out after another child pushed her child off the swing. Then Schachter and Singer conducted another part of the study, using new participants. Lazarus argued that the cognitive activity involved in interpreting emotional context could be conscious or unconscious and may or may not take the form of conceptual processing.

She feels happy so she calls out for her family and tells them the good news. The mother is feeling anger as a result of watching another kid push her child off the swing. In the high arousal relationship, for instance, the partners may be uncertain whether the emotion they are feeling is love, hate, or both at the same time sound familiar? A dominant theory of emotion of Cannon's time was the of emotion, and Cannon recognized that to test this theory, an examination of emotional expression with no visceral afferent feedback was required. Then the men were left alone with a confederate who they thought had received the same injection. One limitation of this theory is that it is not known exactly what causes the changes in the body, so it is unclear whether those changes should be considered part of the emotion itself. These changes are typical of intense emotional states.

The Cannon

For many, this remains the best formulation of emotion. In situations that are accompanied by high arousal, people may be unsure what emotion they are experiencing. The key component of the Cannon—Bard theory of emotion is that when the thalamic discharge occurs, the bodily changes occur almost simultaneously with the emotional experience. If you have been running, your heart is racing, and you are breathing heavier, but you are not having an emotional reaction to it. This seems to be a very strange reaction to such a positive outcome for the university and the students, but it can be explained through the spillover of the arousal caused by happiness to destructive behaviors. Where James-Lange theory represented a physiological explanation for emotions, the Cannon-Bard theory represents and neurobiological approach. Perhaps you remember being flushed, your heart pounding, feeling sick to your stomach, or having trouble breathing.

On the other hand, they argued that people who already have a clear label for their arousal would have no need to search for a relevant label, and therefore should not experience an emotion. Like the James—Lange and Cannon—Bard theories, the Schachter—Singer theory of emotion also known as the two-factor theory attempts to explain emotion as it relates to physiological arousal. Instructor: Michele Chism Michele is presently a part time adjunct instructor at Faulkner University in the Counselor Education Department where she teaches Measurement and Assessment and Diagnosis and Treatment. The men in the e pi n eph r i n e in f o r m e d condition were told the truth about the effects of the drug—they were told that they would likely experience tremors, their hands would start to shake, their hearts would start to pound, and their faces might get warm and flushed. Contrary to the James—Lange theory, therefore, which asserts that emotions arise from physiological arousal, this theory argues that bodily changes can support conscious emotional experiences but do not necessarily cause them.
