Emotion: a complex psychological state or response 1) Physiological arousal 2) Expressive behaviours 3) Consciously experienced thoughts and feelings
James-Lange Theory: Our experience of emotion is our awareness of our physiological responses to emotion-arousing stimuli.
Perception of stimulus (car)  arousal (pounding heart)  emotion (fear)
Cannon-Bard Theory: An emotion-arousing stimulus simultaneously triggers (1) 
physiological responses and (2) the experience of emotion perception of stimulus  arousal & emotion
Schacter-Singer Two-Factor Theory: To experience emotion one must (1) be physically aroused and (2) cognitively label the arousal. perception of stimulus  arousal & cognitive label (I'm afraid)  emotion
Emotional arousal and physiological responses are controlled by the divisions of the autonomic nervous system:

-Julie will be competing in a basketball free throw contest. Her performance is likely to be best if her physiological arousal during the performance is moderate.
-Difficult tasks are better with low arousal, easy tasks are performed better with higher arousal.
• More activity in amygdala when watching fearful (vs. angry) faces
• Negative emotions= right hemisphere positive emotions= left hemisphere
Robert Zajonc: Emotions need no inferences; We can have emotional reactions apart from (and even before) we interpret a situation.
Example: Participants subliminally primed with a happy face rate a subsequent ideograph as more positive than when primed with a sad face
Speedy low road: fear stimulus  thalamus  amygdala  fear response
(bypasses prefrontal & sensory cortex's)
-When fearful eyes were subliminally presented to participants, fMRI scans revealed higher levels of activity in the Amygdala
-Feigned smile 4-5 seconds, genuine smile fades by then
-Gender neutral face when expressing happiness=female, anger=male
-Womens faces show more emotion than men, although they report the same
-Japanese emotion:

    The James-Lange theory suggest that emotion induced stimuli received and interpreted by the brain cortex trigger changes in visceral organs by way of the autonomic nervous system as well as in the skeletal muscles via the somatic nervous system (Pinel, 2009). These changes are then responsible for emotion in the brain (Pinel, 2009).…

    “Historical theories of Emotion and Arousal”

    According to Cannon’s theory physiological arousal is merely an indication that the organism is ready or prepared for an emergency response, such as fighting or fleeing. When a person jumps from a high level, they tend to get their bodies ready for when they reach the ground. Not only does the individual get ready to land properly, their bodies set themselves up to the proper way to jump. According to Cannon (1927, 1929/1953) these emergency responses make the organism more capable in dealing with situations that produce fear, rage, and pain. These states are felt as urges and impulses to act in a certain fashion depending on the emotional experience. Thus, when frustrated a person may have an urge to yell insults or when in love a person may have the impulse to touch another person. Emotions and action readiness are linked together (Cannon, 1929/1953).…

    Charles Darwin's Theory Of Emotions

    Emotions seem to rule our every day life. We make all of our decisions based on whether we feel happy, sad, scared, angry or disgusted. An emotion is a complex psychological state that involves three distinct components: a subjective experience, a psychological response, and a behavioural or expressive response (Hockenbury & Hockenbury, 2007). Charles Darwin (1809-1882) is the father of emotion; he published the first ever book about the study of biopsychology of emotion - “The Expression of Emotions in Man and Animals” (Darwin, 1872). In his book he made two major contributions, one, that animal emotions are similar to human emotions, and the other, that there are fundamental and basic emotions present across all species. For him, emotion…

    According to (Pinel, 2009, P. 435) emotional expression is believed to be controlled by several interconnected neural structures, the limbic system, which is a collection of nuclei and tracts that border the thalamus. These structures include the amygdala, mammillary body, hippocampus, fornix, cortex of the cingulate gyrus, septum, olfactory bulb, and hypothalamus. Papez believed that emotional states are expressed through actions of limbic structures in the hypothalamus and that they are experienced through actions of limbic structures in the cortex.…

    processing. It is crucial for motivating certain behaviours, such as mobility, the pursuit of nutrition, the fight-or-flight response and sexual activity (see Masters and Johnson's human sexual response cycle, where it is known as the arousal phase). It is also very important in emotion, and has been included as a part of many influential theories such as the James-Lange theory of emotion. According to Hans Eysenck, differences in baseline arousal level lead people to be either extraverts or introverts. Later research suggest it is most likely that extroverts and introverts have different arousability. Their baseline arousal level is the same, but the response to stimulation is different.[1]…

    Theories Of Emotion

    The main theories of emotion can be put into three major categories. Physiologists theorize that reactions within the body and mind are responsible for emotions. Neurological theories propose that chemical activity within the brain leads to emotional reflexes. Finally, cognitive theories argue that thoughts and mental activity play a vital role in the formation of emotions.…

    Three Major Theories Of Emotion Analysis

    There are three significant theories of emotion that attempt to describe and explain the way we respond emotionally to stimuli. The first theory was created by William James and Carl Lange and is known as the James-Lange theory. They believed that our body responds first and then we interpret that response in an emotion. Alternatively, the second theory created by Walter Cannon and Philip Bard was called the Cannon-Bard theory and claimed that we have a bodily and emotional response simultaneously. Finally, we have the Schachter-Singer Cognitive Arousal Theory which was created by Stanley Schachter and Jerome E. Singer. They believed that before we feel an emotion, there is a physical arousal and a label of that arousal is created concurrently.…

    It was important, not because it definitively answered the question it raised, but because of the way in which James phrased his response. He conceived of an emotion in terms of a sequence of events that starts with the occurrence of an arousing stimulus {the sympathetic nervous system or the parasympathetic nervous system}; and ends with a passionate feeling, a conscious emotional experience. A major goal of emotion research is still to elucidate this stimulus-to-feeling sequence—to figure out what processes come between the stimulus and the…

    Emotions Paper

    The theory discusses how emotions are directly affected by the physiological arousal of the body in reaction to an exciting stimulus (Deckers, 2010). According to the James-Lange theory one will feel emotions in a specific sequence. The theory 's sequence is emotional stimulus followed by physiological response leading to an affective experience (Deckers, 2010). For example, if a person is involved in a car accident he or she will feel the physiological responses of the body. One may experience heart pounding, hands shaking, or jaw tightening. These responses bring forth emotions like fear, panic, anger, or anxiety. Therefore the physiological arousal is what determines the emotions (Deckers, 2010).…
