-1Lecture 6 - Emotion & Morality
à Emotion:
What is an emotion?:
à a brief physiological and psychological response to an event that is felt subjectively and
prepares a person for action
What is not an emotion?:
à moods are not emotions (moods tend to last a long time, emotion has to a rise and fall in
4 minutes)
à sentiments are not emotions
à personality traits are not emotions
à arousal (e.g. sleepiness) is not strictly an emotion
Why not mood?
à Moods are diffuse
- don’t need to have an eliciting cause
- don’t need to have a target
à Moods may not call for an action
à moods persist over time
Classes of emotions:
à 6 basic emotions
1. fear
2. anger
3. Disgust
4. Sadness
5. Happiness
6. Surprise
Paul Ekman
à complex emotions: blends of basic emotions.
- positive emotions: positively-valanced emotions (mostly complex)
- most studied examples:
- gratitude, contentment, amusement, desire, love (contested)
- self-conscious: complex emotions elicited by the self
- most studied examples:
- pride +, shame - (personal), guilt - (towards someone else),
embarrassment +/-

à Self-report: reliable method
à facial EMG: muscles are linked with our emotions
Levator labi: disgust
Curragator supercilious: negative
orbicular is oculi: real smile vs. fake smile. [zygomaticus major (side muscles on your
cheeks) - more activity in those muscles when youre feeling good]
Natural response is symmetrical
Duchen: through facial displays we understand emotions and react to them
How do we measure this?
EMG - Electromyography
à captures subtle facial movements
à best used for situations where facial movements is not visually detecable
à obtrusive measurement technique
We use emg when we’re trying to pick up subtle emotions, not visible to the eye
EMG limit’s the type of experiments you can do because its in your face (literally)
Facial Action Coding System (FACS)
à
know someone will be making a facial display, then you can use FACS
- sitting in lab, sitting in front of a tv screen and then a camera will be directly on
your face - then I show you a bunch of pictures
à needs to be facs trained. Gave a number to every muscle in the face à facial action
units. You stop the image, frame by frame esp 4 mins after its been presenting, tick of
which numbers have been activated. Then by matching them, you find out what emotion
was expressed
Measure: self report, or EMG, FACS
Components of Emotion:
Definition: an emotion is universal, functional reaction to an external stimulus event,
temporarily integrating physiological, cognitive, phenomenological, and behavioral
channels to facilitate a fitness-enhancing, environment-shaping response to a current
situation.
-- Temporal component: integrates: host of responses. Stimulus goes away, so will the
integration across the different domains
-- Physiological & Emotion:
à Emotions in peripheral nervous system:
- not brain or spinal cord. - Sympathetic and parasympathetic nervous systems:
Response to an event across those systems. Eg. Heart rate, skin conductance, pre ejection
period (heart beats, pushes blood out), finger temperature
= indicate degree of arousal
-Brain is highly equipped to process emotion
Limbic system:

Amygdala: fear & anger
Hippocampus: laughter
Frontal Cortex:
Everything else.
Physiology & Emotion: Proper Inference
à Physiology allows us to get a sense of how aroused people are and how intense. BUT
specific emotions cannot be identified by examing physiological states. Cant read your
mind, by reading your body.
Temporal: Short lived
à
doesn’t last longer than 4 minutes in response to a particular stimulus
___________________________
Two theory of Emotion
James- Lange Theory of Emotion:
à Specific bodily (physic) response tell us what emotion we are feeling. Feel something in
my body, systemically will make me feel an emotion.
One pattern that is sadness, one is fear, etc.
à Bodily response is specific
Event - specific bodily response - subjective emotion
Example:
Caveman. Perception of event: see a bear.
Bodily expression: swear, increased heart rate à RUN! Because of the emotional response
you know you are afraid. Subjective experience: become afraid
Feedback to the system:
Levenson, Ekman & Friesen
Facial displays you make can make you feel an emtion. (sad? Smile and you will feel
better)
Method:
1.Tell participants to pose face in certain ways
- “Directed facial action task”
2. Ask them what expression they are demonstrating
3. Measure physiological responses
Results:
à Participants were able to identify emotions from instructions
à reliable physic profiles (
This case, he seen reliable patterns of body of reactions. Havent shown physic comes first,
observe the physic then the emotion. But can give you an emotion and then observe a
physic response.
