Q

Facial feedback hypothesis

A
  1. Facial expression > Physiological sensation > Emotion
  2. Related to James-Lange Theory

Example: Frown > Tensed muscles > Stress

Q

Cannon-Bard Theory

A
  1. Event > Thalamus sends signals to cerebral cortex and sympathetic nervous system > Physiological sensation AND emotion
  2. All emotions have similar physiological arousal (different emotions are not due to different physiological sensations)

Q

Schachter and Singer’s Two-Factor Theory (AKA Cognitive Arousal Theory)

A
  1. Event > Physiological sensation > Attribution/cognitive label > Emotion
  2. Based on “epinephrine studies”
  3. Led to “misattribution of arousal” research
  4. Led to “excitation transfer theory” research

Q

Schachter and Singer’s epinephrine studies

A
  1. Foundation for Schachter and Singer’s Two-Factor Theory
  2. Participants w/ unexplained physiological arousal looked to actor to understand emotions

Q

Misattribution of arousal

A
  1. Tendency to mislabel arousal/emotions when cause is unknown or unclear
  2. Originated from Schachter and Singer’s Two-Factor Theory

Q

Excitation Transfer Theory

A
  1. NOT the same as misattribution of arousal (although it incorporates that concept)
  2. Arousal from one event can increase arousal during later unrelated event

Q

Three assumptions of Excitation Transfer Theory

A
  1. Physiological arousal can decrease slowly after event
  2. “Residual arousal” can increase later arousal
  3. People can misattribute arousal to later event only and not the earlier event too

Q

Three types of appraisals in Lazarus’s Cognitive Appraisal Theory

A
  1. Primary appraisal - event is irrelevant, positive, or stressful (threat, challenge, harm/loss)
  2. Secondary appraisal - determining coping skills and their potential effectiveness when event is stressful
  3. Reappraisal - monitor and change primary/secondary appraisals as needed

Q

LeDoux’s Two-System Theory

A
  1. Primarily focused on fear
  2. Fear driven by two interacting systems responding to threatening events

Q

Subcortical system in LeDoux’s Two-System Theory

A
  1. Survival system
  2. Quick and automatic defense response
  3. Amygdala
  4. Used to be called “low road”

Q

Cortical system in LeDoux’s Two-System Theory

A
  1. Conscious emotional system
  2. Processes sensory information and uses cognitive processes (memory, attention, reasoning) to determine whether fear is warranted
  3. Cortices (visual, prefrontal, parietal)
  4. Used to be called “high road”

16
Q

Papez circuit

A
  1. Linked emotions to specific brain areas
  2. Subsequent research focuses more on memory as an important mediator of emotions
17
Q

Cerebral cortex and emotions

A
  1. Left/dominant hemisphere - happiness and positive emotions, damage leads to strong negative emotions
  2. Right hemisphere - sadness and negative emotions, damage leads to indifference or euphoria
18
Q

Amygdala and emotions

A
  1. Recognizing fear in facial expressions
  2. Attaching emotions to memories
  3. Determining emotional significance of event and adjusting emotion accordingly
  4. Stimulation leads to rage, fear
  5. Damage leads to loss of fear
19
Q

Hypothalamus and emotions

A
  1. Regulates physical signs of emotions through ANS and pituitary gland
  2. Stimulation leads to pleasure, fear
  3. Damage leads to rage
20
Q

Selye’s General Adaptation Syndrome

A
  1. Body’s response to all types of stress is the same
  2. Three stages of body’s response to stress
21
Q

3 stages of General Adaptation Syndrome

A
  1. Alarm reaction stage
  2. Resistance stage
  3. Exhaustion stage
22
Q

Alarm reaction stage in General Adaptation Syndrome

A

Increased activity in SNS > increased energy > fight-or-flight response

23
Q

Resistance stage in General Adaptation Syndrome

A

(If stressor from alarm reaction stage persists)
1. Some physical sensations return to normal
2. Cortisol remains elevated to give body enough energy to cope

24
Q

Exhaustion stage in General Adaptation Syndrome

A

(If stressor from alarm reaction stage and resistance stage persists)
1. Physical processes break down

Example: job-related satisfaction, commitment, and stress

25
Q

Main critique of Selye’s General Adaptation Syndrome

A

Responses to stress are not always the same and can depend on the type of stress, genetics, previous experiences, etc.

26
Q

McEwen’s Allostatic Load Model

A
  1. Brain is primary in stress because it determines what is stressful and how to respond to stress
  2. Amygdala, hippocampus, and prefrontal cortex are most important
  3. Allostasis > allostatic state > allostatic load > allostatic overload
27
Q

Allostasis (Allostatic Load Model)

A

Processes that allow the body to adapt to change and stabilize

Example: elevated blood pressure and cortisol

28
Q

Allostatic state (Allostatic Load Model)

A

Allostasis processes being maintained for a time without consequences

29
Q

Allostatic load (Allostatic Load Model)

A

Prolonged allostatic state (due to chronic stress or multiple acute stressors) that results in consequences on the body

30
Q

Allostatic overload (Allostatic Load Model)

A

Prolonged allostatic overload that results in more severe consequences on the body

Can lead to weaker immune system, PTSD, depression, substance use, etc.
