Ch 12: Emotions, Stress, and Health Flashcards
What are the three components of emotions?
- Bodily arousal
- Expressive behaviours
- Conscious experience: Thoughts and feelings
Emotion is a full body/mind/behavioural response to a situation
Emotion Theory: James-Langue Theory
First comes conscious awareness, then the feeling.
Emotion follows the bodily response to a stimulus event.
- Stimulus
- Response: Body arousal
- Cognitive awareness & label for the feeling
Emotion Theory: Cannon-Bard Theory
Bodily/physiological responses and experienced (subjective) emotions occur separately but simultaneously.
One does NOT affect the other.
Emotion-arousing stimulus triggers…
Physiological responses + Subject experience of emotion, SIMULTANEOUSLY.
How do spinal cord injury patients defy the Cannon-Bard theory?
According to their theory, spinal cord patients would not notice a difference in their experience of emotion after injury.
However, a study revealed that these patients experienced some emotions less intensely, others more intensely.
If Cannon and Bard were correct, people who suffer spinal cord injuries should not notice a difference in their experience of emotion after the injury
However, according to one study of 25 World War II soldiers:
- Participants with lower-spine injuries reported little change in their emotional intensity
- Participants with the high spinal cord (below the neck) injuries reported that emotions were less intense than before the injuries.
Emotion Theory: Schachter and Singer Two-Factory Theory
Emotion requires a conscious interpretation of arousal.
Our physical reactions (physiology) and our thoughts (cognitions - perceptions, memories, interpretations) together create emotion.
EMOTION = AROUSAL + LABEL = PHYSICAL AROUSAL + COGNITIVE APPRAISAL
According to the two-factor theory, arousal _______ from one event to the next.
Spills over!
A stirred-up state can be experienced as one emotion or another, depending on how we interpret and label it.
Two-factor theory: Arousal _______ emotions, cognition ________ it.
Arousal FUELS emotion, cognition CHANNELS it.
Emotion Theory: Zajouc-LeDoux Direct Emotion Theory
We have many emotional reactions apart from, or even before, our interpretation of a situation.
Emotional responses sometimes occur before we even have time to consciously interpret/appraise the event.
What are the two possible neural pathways of emotions?
- HIGH ROAD: Especially in more complex feelings.
A stimulus travels by the way of the thalamus to the brain’s cortex.
At the cortex, it is analyzed and label, before the response command is sent out via the amygdala (emotion-control centre). - LOW ROAD: Especially in simple emotions, such as likes, dislikes, fears.
A neural shortcut that bypasses the cortex. Via the thalamus, the input is directed to the amygdala, for an instant emotional reaction.
Emotion Theory: Lazarus Cognitive Mediational Theory
Some emotional responses don’t require conscious thinking. Though the appraisal may be effortless and unconscious, it is still a mental function.
Emotions arise when we APPRAISE, whether or not we are aware of this appraisal…
aka, this interpretation may not read our conscious awarness.
What is the role of the sympathetic division of your autonomic nervous system in a crisis situation?
It mobilizes your body for action.
Your adrenal glands release stress hormones, including epinephrine (adrenaline) and norepinephrine (noradrenaline).
Your liver pours extra sugar into your bloodstream, providing energy.
Your heart rate, blood pressure, respiration increase.
How does arousal affect performance, according to the Yerkes-Dodson law?
Arousal affects performance in different ways, depending on the task.
Moderate arousal leads to optimal performance.
What is the role of the parasympathetic division of the ANS?
When the crisis passes, it calms down the body.
Do different emotions activate different physiological and brain-pattern responses?
- Different emotions can share common biological signatures = Physiological responses
- A single brain region can dictate different emotions = Multitasking brain regions
Our emotions ____ different to us, ____ different to others.
Feel; look.
Fear and joy stimulate different _______.
Facial muscles.
Inside the brain, how can emotions differ?
In their brain circuits - activating different areas of the brain.
How can we recognize different emotions?
Facial expressions and brain activity.
What is a polygraph?
A lie detector that measures emotion-linked changes in breathing, cardiovascular activity, and perspiration.
What criticism do polygraphs face?
- Our physiological arousal is much the same from one emotion to another.
- Many innocent people respond with heightened tension to the accusations implied by the critical questions.
Which lie detection approaches are more effective?
Guilty knowledge tests, which assesses physiological responses to crime-scene details only known to the police and the guilty.
fMRIs, which show activity in the brain that varies between the liar and the honest.
________ influences how we perceive emotions, _________ us to some.
Experience; sensitizing.
What reveals emotions you are trying to conceal?
Hard-to-control facial muscles, such as eyebrow lifting, your smile.
Which expressions do we find difficult to detect, despite our brain’s emotion-detecting skills?
Deceiving expressions, as the behavioural differences between liars and truth-tellers are too minute.
