8 - Emotion and Motivation Flashcards
Leonard
creepy robot that learned how to respond to emotions but doesn’t actually have them himself.
two dimensions of emotion
arousal (high and low) and valence (positive and negative)
emotion
a positive or negative experience that is associated with a particular pattern of physiological activity
James-Lange theory
(of emotion) A stimulus triggers activity in the body, which in turn produces an emotional experience in the brain
What did William James and Carl Lange suggest about emotion?
the events that produce an emotion might actually happen in the opposite order. ex: see the bear, hearts starts pounding then experience fear, which is nothing more than your experience of your body’s response
Who was Walter Cannon and Philip Bard?
Cannon was James’s former student, Bard was Cannon’s student
Cannon-Bard theory
a stimulus simultaneously triggers activity in the body and emotional experiences in the brain
In what ways did Cannon claim his theory was better than James-Lange?
- Emotions happen quickly while the body often reacts slowly (ex: blushing)
- People often have difficulty accurately detecting bodily responses (ex: heart rates)
- Nonemotional stimuli can cause the same bodily response as emotional stimuli (ex: raise in room temperature)
- Not enough unique patterns of bodily activity to account for all the unique emotional experiences people have
Schacter and Singer’s two factor theory
emotions are based on inferences about the causes of physiological arousal (ex: see bear in kitchen, heart starts to pound, brain scans environment, notices bear, makes logical inference, and interprets your arousal as fear)
Heinrich Kluver and Paul Bucy’s discovery
when monkey’s amygdala was accidentally damaged during surgery, the monkey seemed absolutely fearless and unflappable, and was unable to distinguish between good and bad food, or good and bad mates
When people with amygdala damage see a threat vs when they experience a threat
see = no fear, experience = feel fear (ex: finding they can’t breathe)
Emotion recognition and the amygdala
patient with amygdala damage could recognize happiness, sadness, and surprise, but not anger, disgust, and fear
appraisal
an evaluation of the emotion-relevant aspects of a stimulus
Fast pathway
from thalamus directly to amygdala
Slow pathway
thalamus to cortex to amygdala
What is the implication of the fast and slow pathway?
because the amygdala receives information from the thalamus before it receives information from the cortex, people can be afraid of something before they know what it is
the amygdala is to the cortex like….
…a gas pedal is to the brakes
Adults with cortical damage and children (whose cortices are not fully developed) have difficulty in what?
inhibiting their emotions
when asked to experience emotions like sadness, fear, and anger, there is increased/decreased activity where?
increased activity in the amygdala and decreased activity in the cortex
when asked to inhibit emotions like sadness, fear, and anger, there is increased/decreased activity where?
decreased activity in the amygdala and increased activity in the cortex
emotion regulation
the strategies people use to influence their own emotional experience
reappraisal
changing one’s emotional experience by changing the way one thinks about the emotion-eliciting stimulus
examples of reappraisal
watching circumcision video described as joyous religious ritual will result in slower heart rates and less distress reported
picture of woman crying at funeral changed to imagining woman at wedding, amygdala is active at first, then cortex becomes active and the amygdala is deactivated
Emotional expression
an observable sign of emotional state, humans do it pretty naturally
Paul Ekman and Wallace Friesen
catalogues the muscle movements of which the human face is capable. Isolated 46 unique movements, which they called action units with a number and name like “cheek puffer” and “dimpler”
The creation of the emoticon
Sept 19 1982, Scott Fahlman posted on Internet user’s group that :-) should indicate a joke
Evolutionary significance of emotional expression
convenient way for animals to let other animals know how it is feeling and therefore how it is prepared to act
Universality hypothesis
emotional expressions have the same meaning for everyone (Darwin)
Support for the universality hypothesis
blind people smile when they are happy
two day old infants make a face of disgust when they eat bitter things
preliterate/isolated cultures recognize and label expressions with the same emotions as “we” do
Six emotions that are probably universal, and others that might be
anger, disgust, fear, happiness, sadness, surprise; embarrassment, amusement, guilt, shame, pride
facial feedback hypothesis
emotional expressions can cause the emotional experiences they signify (ex: people are happier when holding a pencil between their teeth than their lips, odors are less pleasant when the nose is wrinkled)
Body vs the face when identifying emotion
People think they use the face to identify emotion, but they actually use the body more
Botox and emotion
Because Botox impairs the formation of facial expressions, it impairs both the experience of emotions and ability to process emotional information
