10 - Emotion and Motivation Flashcards
Emotion (or affect - affective disorder = emotion based disorder)
an immediate, specific negative or positive response to environmental events or internal thoughts
Primary emotions
Emotions that are innate, evolutionarily adaptive, and universal (shared across cultures)
- associated with specific physical states
Secondary emotions
blends of primary emotions
ex. remorse, quilt, submission, anticipation
Feelings
the subjective experience of the emotion, not the emotion itself (ex. feeling scared)
Mood
long-term emotional states
- do not have an identifiable trigger or specific behavioural and psychological response
Alexithymus
if it’s so common, why is it not very visible?
a disorder in which people do not experience emotion’s subjective component
- usually comorbid with something else ex. autism or something that would be more visible than alexithymus
Circumplex model
arousal
- how activating an emotion is (brain and body activation)
- physiological activation (ex. increased brain activity) or increased autonomic responses (ex. quick heart-rate, sweating, muscle tension)
Circumplex model
valence
how negative or positive an emotion is
circumplex model of emotion
- emotions categorized by valence and arousal
How does the insula play a role in emotional experience?
- receives and integrates somatosensory signals from the whole body
- awareness of bodily states
- particularly active when people experience disgust
How does the amygdala play a role in emotional experience?
- relay between sensory systems and systems responsible for behavioural, autonomic, and hormonal responses
- processes the emotional significance of stimuli and generates immediate emotional and behavioural reactions
What are some affects of a damaged amygdala in relation to emotional experience?
- difficulty judging the intensity of fearful expressions and reacting to them
- when they do distinguish the difference, they likley won’t use that information anyways
How does the amygdala help with long-term memory?
- emotional events are likely to increase activity in the amygdala and increased activity is likely to improve long-term memory for the event
- modifies how the hippocampus consolidates memory
amygdala
Q: when wading in the ocean, you sense a dark figure under the water, so you freeze. When you realize it is your own shadow and not a shark, you relax. How did the fast and slow paths for visual info contribute to your emotional response?
2 ways info reaches the amygdala:
The first path processes info instantly (resulting in the fear respose) and the second path is more deliberate and thorough (reassures you it’s just your shadow)
Theories of emotion
Common Sense Theory
body responds to emotion
theories of emotion
James-Lange Theory
bodily response causes emotional response (ex. seeing the bear causes your heart to race, and you perceive your racing heart as fear)
- believed there were patterns
theories of emotion
Canon-Bard Theory
- mind + body experience emotions independently
- bodily response (hormones through the bloodstream) is slower than cognitive response (neural impulses)
- believed there were too many emotions for them each to have a pattern
theories of emotion
Schachter-Singer Two-Factor Theory
- physiological response to all emotional stimuli is essentially the same
- arousal is interpreted differently based on the situation and the given label (people feel the need to search for the source of arousal and identify it)
Facial feedback hypothesis
idea that you can activate an emotion by molding your facial muscles into the associated expression
