Exam 2 Flashcards
Emotions - what purpose do they serve?
Evolutionary functions
- innate
- universal
- conserved
Evidence for evolutionary basis of emotions
- emerge early w/o direct reinforcements
- avoidance mechanisms (may be adaptive)
- similarities w/nonhuman animals
What is the discrete emotions theory?
The theory that humans experience a small number of distinct emotions that are rooted in their biology
What supports the theory that emotions are universal?
Ekman’s research with primary emotions
How many primary emotions are there? What are they? What makes them a primary emotion?
Seven basic emotions:
- happiness
- disgust
- sadness
- fear
- surprise
- contempt
- anger
—primary bc easier to distinguish from facial expressions
What are three aspects of the Discrete emotions theory?
Emotions are:
- universal
- physiological responses
- display rules
What are display rules in terms of emotions? Give an example
Humans have all of the primary emotions, but may not express all of them due to cultural differences
- does not influence the emotion itself, but rather the expression of it
- ie: societal demands in western culture with boys crying
How do cognitive theories of emotion consider emotion?
They consider emotion to be a product of thinking
What are the three cognitive theories of emotion?
- James-Lange
- Cannon-Bard
- Two Factor
What is the James-Lange theory? Give an example with a spider
Emotions are a result from interpretation of out bodily reactions to stimuli
-ie: person sees spider -> begins to shake -> interprets shaking as fear
What is the Cannon-Bard theory? What organ is supposedly responsible for this? Give an example with a spider
Emotion-provoking events lead simultaneously to an emotion and to bodily reactions
- –believed to be done through the Thalamus
- ie: person sees spider -> begins to shake AND experiences fear at same time
What is the Two-factor theory? Give an example with a spider
Emotions are produced by an undifferentiated state of aroused along w/an attribution of that arousal
-ie: person sees spider -> undiff. state of arousal (fear, happiness, etc.) -> attributes arousal to spider -> experiences fear
How does arousal and attraction correlate to each other? Give an example
Any type of arousal is more likely to lead to more attraction
- ie: attractive female research assistant on solid bridge and wobbly bridge talking to passerbys
- –> those approached on wobbly bridge was found more likely to call back
What is an example of an unconscious influence? What discovery did it lead to?
Subliminal presentation of emotional stimuli
-Mere exposure effect
Mere exposure effect - what is it?
Repeated exposure to a stimulus makes us more likely to feel favorably toward it
What are some examples of stimuli that are applicable to the mere exposure effect?
- Faces
- Shapes
- Nonsense syllables
- Chinese characters
What is one test used to detect lying? What does it rely on?
Polygraph test
-relies on the Pinocchio response
What is the Pinocchio response?
a perfect (supposedly) physiological or behavioral indicator of lying
What are the physiological signals that a polygraph measures? What do these signals traditionally reflect?
Reflect anxiety
- perspiration
- blood pressure
- heart rate
What type of questions are asked in a controlled questions test?
yes/no questions
- relevant
- control
- irrelevant
What do irrelevant questions do? Give an example
Establish a baseline (individual’s typical level of arousal)
-ie: Is your name Sam?
What are characteristics of control questions?
Broader in scope and may involve past
What are the three possible results of a polygraph test?
- Not deceptive
- Inconclusive
- Deception detected
What does a test result of “not deceptive” mean, physiologically?
higher level of response for control questions
