Chapter 12 - Part 1: Emotion Flashcards
emotion
- a mix of physiological activation, expressive behaviours, and conscious experiences
- more than just a feeling - a physiological activation, a behavioural mobilization
functions of our emotions
- enhance survival
- focus our attention and energize our action
- strongest when we have strong want/need to avoid or obtain something
6 theories of emotion
- common-sense view
- James-Lange theory
- Cannon-Bard theory
- 2-factor theory
- Zajonc/Ledoux theory
- Lazarus theory
common sense view
thought (am I safe in this dark alley?) leads to emotion (fear) leads to physiological response (heart racing)
James-Lange theory
- physiological arousal comes before emotion
- ex. heart races, then we feel afraid
Cannon-Bard theory
- physiological arousal and emotion happen simultaneously
- ex. your heart begins pounding as you begin to experience fear
2-factor theory
- emotion = physical arousal + cognitive label
- ex. you may interpret arousal as fear or excitement depending on the context
- supported by the misattribution to the 2-factor theory of arousal (ie. Capilano Suspension bridge examples)
embodied emotion
emotions involve bodily responses (ex. butterflies in our stomach, racing heart, neurons activated in the brain)
autonomic nervous system
- mobilizes us for action (ex. by pumping blood to major muscle groups)
- 2 main branches: sympathetic (arousing, stress hormones) and parasympathetic (calming, inhibition of stress hormones)
emotions can have both physiological ____ and physiological ____
- similarities (ex. difficult to distinguish between fear vs. anger vs. love vs. boredom)
- differences (ex. different facial muscles used in fear vs. joy; amygdala activity in fear vs. anger; frontal lobe activity in depression vs. happiness)
Lie detector tests
- liars vs. truth-tellers experience different emotions when asked questions
- problem: different emotions don’t have distinct physiological signatures -> results in huge inaccuracies
cognition and emotion
many assume cognition comes first, and that it’s required for emotion, but that’s not always true (ex. spillover phenomena; subliminal messages triggering activity)
Spillover Phenomena
- arousal from previous event influences reaction to next event, or “catching” the emotions of people near you
- ex. being angry right before something happens will have a large effect on the way you react to it; being around angry people will make you angrier
2 routes to emotion
- with conscious appraisal
- without conscious appraisal
Zajonc/Ledoux Perspective
- instant emotion without cognition/appraisal
- neural shortcut that bypasses cortex (‘thinking’ part of brain) to create fear (ex. we automatically fear a sound in a forest before labeling it as a threat; fearing a spider even though we know it’s harmless)
perceiving facial expressions
- emotions expressed in many ways (face, body, voice)
- angry faces “pop out” faster than happy ones (more adaptive for us to recognize unhappy faces -> helps us perceive potential threats faster)
