Motivation and Emotion PowerPoint Presentation by Jim Foley 2013 Worth Publishers Module 30: Theories and Physiology of Emotion How Emotions relate to your thoughts and your body Physiological Arousal: Comes before emotion (James-Lange theory) Comes with emotion (Cannon-Bard theory) Becomes an emotion when cognitive appraisal/label is
added (Shacter-Singer two-factor theory) Emotions and the brain: Sometimes cognition is bypassed in emotional reactions Emotions and the body: The Autonomic Nervous system Emotions with different brain and body response patterns Emotion: Arousal, Behavior, and Cognition Someone cuts you off on the road. You may feel the emotion of anger. Emotions are a mix of: Expressive behavior: yelling, accelerating Bodily arousal: sweat, pounding heart Conscious experience: (thoughts, especially the labeling of the emotion)
What a bad driver! I am angry, even scared; better calm down. How do these components of emotion interact and relate to each other? Do our thoughts trigger our emotions, or are they a product of our emotions? How are the bodily signs triggered? How do we decide which emotion were feeling? An emotion is a full body/ mind/behavior response to a situation.
Theories of Emotion: The Arousal and Cognition Chicken and Egg Debates Which came first, the chicken or the egg? Or did they evolve together? Which happens first, the body changes that go with an emotion, or the thoughts (conscious awareness and labeling of an emotion), or do they happen together? James-Lange Theory: body before thoughts Cannon-Bard Theory:
body with thoughts Singer-Schachter/Twofactor theory: body plus thoughts/label Zajonc, LeDoux, Lazarus: body/brain without conscious thoughts James-Lange Theory: Body Before Thoughts William James (1842-1910): We feel afraid because we tremble, sorry because we cry. The James-Lange theory states that emotion is our conscious awareness of our physiological responses to stimuli. Our body arousal happens first, and then
the cognitive awareness and label for the feeling: Im angry. According to this theory, if something makes us smile, we may then feel happy. Cannon-Bard Theory: Simultaneous Body Response and Cognitive Experience The Cannon-Bard theory asserts that we have a conscious/cognitive experience of an emotion at the same time as our body is responding, not afterward.
Human body responses run parallel to the cognitive responses rather than causing them. Adjusting the Cannon-Bard Theory Emotions are not just a separate mental experience. When our body responses are blocked, emotions do not feel as intense. Our cognitions influence our emotions in many ways, including our interpretations of stimuli:
Is that a threat? Then Im afraid. Schachter-Singer Two-factor Theory: Emotion = Body Plus a Cognitive Label The Schachter-Singer two-factor theory suggests that emotions do not exist until we add a label to whatever body sensations we are feeling. I face a stranger, and my heart is pounding. Is it fear? Excitement? Anger? Lust? Or did I have too much caffeine? The label completes the emotion.
In a study by Stanley Schachter and Jerome Singer in 1962, subjects experienced a spillover effect when arousal was caused by injections of what turned out to be adrenaline. The subjects interpreted their agitation to whatever emotion the others in the room appeared to be feeling; the emotional label spilled over from others. Robert Zajonc, Joseph LeDoux, and Richard Lazarus:
Emotions without Awareness/Cognition Theory: some emotional reactions, especially fears, likes, and dislikes, develop in a low road through the brain, skipping conscious thought. In one study, people showed an amygdala response to certain images (above, left) without being aware of the image or their reaction. When Appraisal Affects Emotion Schachter and Singer highlighted the role of appraisal in labeling emotions: this agitation is fear.
Richard Lazarus noted top- down cognitive appraisal of stimuli (is that a threat, or something I would enjoy?) influences emotion. Summary: Theories of Emotion Theories of Emotion Emotion can include the appraisal of the stimulus such as, is it a threat or not? Avoiding the highway today without identifying or
explaining any fear is an example of the low road of emotion. Is Experienced Emotion as Universal as Expressed Emotion? Carroll Izzard suggested that there are ten basic emotions: those evident at birth (seen here) plus contempt, shame, and guilt. Embodied Emotion: The role of the autonomic nervous system
The physiological arousal felt during various emotions is orchestrated by the sympathetic nervous system, which triggers activity and changes in various organs. Later, the parasympathetic division calms down the body. Embodied Emotion: How Do Emotions Differ in Body Signs? It is difficult to see differences in emotions from tracking heart rate, breathing, and perspiration. There is also a large overlap in the patterns of brain activity across emotions. There are some small differences; for example,
fear triggers more amygdala activity than anger. A general brain pattern: hemispheric differences Positive approach emotions (joy, love, goalseeking) correlate with left frontal lobe activity. Negative withdrawal emotions
(disgust, fear, anger, depression) correlate with right hemisphere activity.
