Gabriela Flashcards
what is an affect?
Psychological states that involves valuation, defined as a relatively quick good-for-me/bad-for-me valuation
What are moods
- low intensity
- diffuse affective states
- no salient antecedent
- little content
What are emotions?
- Short-lived
- Conscious
- Prototypical content
Evolutionary perspectives of emotions
- Emotions selected for survival (Darwin, 1872)
- Emotions as commitment (e.g. love, punishment) for long term goals (Frank, 1998)
- Emotions as superordinate coordination (Cosmides and Tooby, 2000)
What are primary emotions
- Shared with other animals
- E.g. anger, fear, happiness
What are secondary emotions?
- Self conscious or social
- Unique to humans
- Less visible
- Develop later in life
- Have a social regulatory function
- E.g. embarrassment, guilt, shame
How are emotions traditionally seen?
Seen as states with personal relevance that involve specific cognitive, physiological and experiential components
What are macro-expressions?
- Expressions of single emotions that are not concealed
- They last .5 to 4 seconds
- Easy to see
- Mostly universal
- Prototypical, but. not clear cut e.g. a ‘true’ smile vs a ‘fake’ smile
What are micro-expressions?
- Very fast (less than a second)
- Appear in combination. with other emotions
- Often signs of concealed emotions
What is the facial feedback hypothesis?
Stack et al., 1998
McCanne and Anderson, 1987
Facial movement can influence emotional experience
What is Darwin’s (1872) idea of facial emotion?
- Facial expression of emotion evolved as part of the actions necessary for life
Anger –> frowning
- Protects eyes in anticipation of attack
Facial feedback hypothesis study (How funny are cartoons)
Strack, Martin and Stepper, 1988
Manipulation: Activation of facial muscles
Dependent variable: Measure of facial electromyography
- Inhibition or facilitation of smiling muscles modulated how funny cartoons were perceived to be
Divided attention experiment
Larsen et al., 1992
- 30 Ps
- Within-subjects
- Attach two golf tees to the subject’s brow
- Looked to see whether the golf tees pulled together (activates corrugator supercilii)
- Shown aversive photographs
- Measured experience of sadness
- Results showed that frowning led to increased sadness
How does facial feedback work?
- Subtle muscle contractions. in. the perceiver’s face generate an afferent muscular feedback signal from the face to the brain
- Perceiver uses this feedback to reproduce and understand the perceived emotional meaning
What do intrapersonal functions of emotions do?
- Prepare the body for action
- Influence thought
- Motivate for future behaviours
What do interpersonal functions of emotions do?
- Facilitate. specific behaviours in perceivers
- Signal the nature of interpersonal relationships
- Provide incentives for desired social behaviour
How do emotions work?
Emotions simultaneously activate certain systems and deactivate others in order to prevent the chaos of competing systems operating at the same time, allowing for coordinated responses to environmental stimuli
What happens when we are afraid?
- Digestive processes shut down –> dry mouth
- Blood flows disproportionately to lower half of the body
- Visual field expands
- Air is breathed in
What is the James-Lange theory of emotion (1980)?
- Emotions are the perception of physiological conditions that result from a stimulus
E.g. We don’t see a bear, fear it, and run
We see a bear and run, then we fear it
What are the consequences of affect?
- Affect triggers action tendencies
- Activates relevant goals
- Determines selective memory and processing styles
What happened to Phineas Gage?
- Railway explosion on 13 sept 1848 at. 4:30 pm led. to accident
- Gage was alive and had possession of reason but was free of pain
- Had a personality change: Became anti-social, uncaring, impulsive and irrational
- Lesion in Ventromedial region of frontal lobes caused poor rational decision making and processing of emotion
What happens in patients with ventromedial lesions of the frontal lobes?
- Largely preserve intellectual abilities
- Show abnormal personal and social decision making
What is the Somatic Marker Hypothesis?
Damasio (1996)
- Emotional processes guide behaviour, particularly decision making
Somatic markers = feelings in the body that are associated with emotions e.g. rapid heartbeat - anxiety; nausea - disgust
- Thought to be processed in the vmPFC and amygdala
How does arousal facilitate memory consolidation?
Mather and Sutherland (2011)
- Arousing experiences create long lasting memories
- Injections of adrenaline after learning enhance memory
- Exercise improves memory
