After Midterm Flashcards
Walk through what happens when a scary stimulus pops out, leading to emotion. (3 steps)
What is the conclusion? What does our emotional experience depend on?
1) Sensory areas receive stimuli
2) Sends signals to rest of the brain
3) The rest of the brain allows us to consciously think of the event and cause unconscious physical changes
Conclusion: Our emotional experience depends on both conscious and unconscious bodily responses.
Two-factor theory.
Who made this theory? What is it?
Schachter and Singer
Emotions are a combination of:
1) Arousal and
2) Valence
what is arousal and valence in two-factor theory?
Arousal: (degree of) Bodily arousal or activation
Valence: (degree of) positive/negative conscious experience
“how positive/negative is the experience” is what in emotion?
Valence
How is the two-factor theory usually portrayed?
A circle. Arousal on y-axis and Valence on x-axis
Cannon-Bard Theory
Emotional (conscious) experience –> Physiological response = Emotion
James-Lange Theory
Physiological expression –> Conscious response = Emotion
Where’s the amygdala located?
Medial temporal lobe
What’s amygdala’s role in emotions?
Processing fear and emotional memory. Lights up whenever some kind of fear happens.
3 Effector systems
Endocrine
Autonomic
Somatic
Endocrine system
Slow response.
Hormones (bloodstream)
HPA Axis
Cortisol/Stress is in which system?
Endocrine system
What is the HPA axis?
Hypothalamus
Pituitary
Adrenal
Releases hormones. Responds to stress.
In what system is HPA axis?
Endocrine System
How does Amygdala relate to HPA axis?
Amygdala communications to hypothalamus then pitutary and adrenal
What is pituitary’s job?
to release/produce hormones into the bloddstream
What region is pituitary’s boss?
Hypothalamus
What does autonomic system do?
Unconscious responses.
Sympathetic/Parasympathetic.
Body temp, heart rate, breathing, etc.
what system has to do with body temp, heart rate, breathing?
Autonomic system
Which effector system have longer lasting responses?
Endocrine
What does somatic system do?
Muscular responses. Fight/Flight.
PGM
Functions? what system?
periaqueductal gray matter in brain stem
pain modulation, stress response.
somatic system
What other regions inform the somatic system?
Hippocampi and Septal nuclei
How do we become consciously aware of emotions after effector symptoms?
Amygdala does it. Physiology –> Consciousness
What part of brain is activated during regret after a choice with bad outcome?
Valuation circuit
OFC
What is ‘regret’?
When the value of a behavior’s consequence does not correspond to value judgement. A conscious subjective interpretation
What brain regions are more or less active in emotion labelling?
Right vlPFC (more activity)
Amygdala (less activity)
Correlation between vlPFC and Amygdala activity
Negative (r= -.5)
What brain region(s) predict both vlPFC and Amygdala activity?
vmPFC/ACC
vlPFC is important for this EF.
How does this relate to emootions?
inhibitory control
regulates negative emotions
How is conscious perception of a negative emotion related to amygdala activity of it?
Consciously perceiving (by producing speech) negative emotion regulates amygdala response.
Talking about it regulates our responses to them.
Paul Ekman “Lie to Me” research
There exists basic emotions that are universal.
Asked Fori tribe to 1) make face and 2) label expression
Expressed and Recognized same as western
Basic emotions
Anger
Disgust
Fear
Happiness
Sadness
Surprise
4 elements of basic emotions
Evolutionary
Unique
Instinctive (unconscious)
Universal
Blind vs. Non-blind atheletes and emotion.
How does this relate to basic emotion theory?
We have evolutionary ways to express emotion.
blind and non-blind athletes have same expressions when celebrate/lost respectively.
What are complex emotions?
Combinations of basic emotions. Long-lasting feelings that are evolved.
What major brain region did we study is heavily involved in EFs?
What is included?
Prefrontal Cortex (PFC)
Everything that isn’t M1
