Exam 3: Chapters 8-11 Flashcards
Emotion
A temporary state that includes unique subjective experiences and physiological activity, and that prepares people for action
- mental features: what a person thinks, feels, is prepared to do
- physical features: activity of the body and brain
Multidimensional scaling
A scale that estimates the similarity of emotional experience by describing the “distance” between them:
- arousal: how energetic a feeling is; measured from low to high
- valence: how positive a feeling is; measured from negative to positive
Appraisal
Conscious or unconscious evaluations and interpretations of the emotion-relevant aspects of a stimulus or event which ultimately influence the emotions we experience. We evaluate:
- self-relevance
- importance
- ability to cope
- ability to control
- etc.
Action tendencies
A readiness to engage in a specific set of emotion-relevant behaviors; borne from evolutionary purposes, indicating emotion as a survival tactic
- for example: emotion of “fear” associated with action tendency “freezing”
James-Lange Theory
Feelings are simply the perception of ones own physiological responses to a stimulus rather than physical responses that occur due to an emotion; essentially physical response happens first and we perceive that as an emotion
(this is not true)
Two-Factor Theory of Emotion (aka Schacter-Singer Theory)
Revision of James-Lange Theory; every stimuli trigger the same general state of physiological arousal, which is then interpreted as a specific emotion based on context (cognitive appraisal)
Again, not true, but it is true that we can interpret the same physiological response in different emotional ways
Fear pathways
Happen simultaneously, therefore indicating that you can feel fear before you conscious process what you’re afraid of
- slow pathway
- fast pathway
Slow fear pathway
Stimulus processed in thalamus, then cortex (processing), then amygdala (emotion)
Fast fear pathway
Stimulus processed in thalamus then amygdala (emotion), not allowing for processing of the stimulus before emotion is produced
Emotional expression
An observable sign of an emotional state (i.e. facial expressions)
Basic facial expressions
- anger
- fear
- disgust
- happiness
- sadness
- surprise
Universality hypothesis
Darwin argued that all emotional expressions mean the same thing to all people in all places at all times; not true, but the New Guinea study showed significant cross-cultural similarities
Facial feedback hypothesis
Imitating emotional expressions can cause the emotional experiences they typically signify
Display rule
A norm for the appropriate expression of emotion, moderated by techniques such as:
- intensification: exaggerating expression of emotion
- deintensification: muting expression of emotion
- masking: expressing one emotion while feeling another
- neutralizing: showing no expression of emotion
Four features that reveal deceptive expression
- morphology (reliable muscles)
- symmetry
- duration
- temporal patterning
How do certain emotions facilitate social behaviors and relationships?
- guilt helps prevent harmful behavior and demonstrates caring, but can be manipulated to control others
- jealousy signals emotional commitment and protects genetic interests, but is a common cause of partner abuse
- embarrassment represents submission to social group and recognition of social error
Mood disorders
Excessively strong emotions
Alexithymia
Difficulty identifying and expressing emotions; trait of autism
Emotion regulation
Use of cognitive and behavioral strategies to influence one’s emotional experience
- cognitive load
- ego depletion
Reappraisal
Changing one’s emotional experience by changing the meaning of the emotion-eliciting stimulus
Compare the four main theories of emotion
Common sense view:
situation -> emotion -> bodily response
James-Lange Theory:
situation -> bodily response -> emotion
Cannon-Bard Theory:
situation -> subcortical brain activity -> simultaneous bodily response and emotion
Schacter-Singer Theory (two-factor):
situation -> simultaneous cognitive appraisal and bodily response -> emotion
Kluver-Bucy Syndrome
Caused by removal of amygdala; characterized by:
- hypersexuality
- fearlessness
- deficits in response to social cues
- fear is harder to condition
Amygdala
- part of the limbic system
- activates emotional facial expressions
- sensitive to fear expression
damage causes difficulty in interpreting expressions and making judgments
The Limbic System
Important for assessing and responding to emotionally relevant stimuli; amygdala and orbitofrontal cortex
Orbitofrontal Cortex
Processes potential reward value and emotional/social cues
Damage causes:
- inappropriate social behavior
- insensitivity to emotions of others
- excessive aggression
Motivation
The internal psychological causes of purposeful behavior. Emotions motivate us by:
- providing us with information
- being the objectives toward which we strive
Drive
Internal state generated by departure from physiological optimality
Instinct
The natural tendency to seek a particular goal
What is the relationship between drive and instinct?
Instinct provides us with certain desires, and our drives attempt to fulfill them
Homeostasis
The tendency for a system to take action to keep itself in equilibrium; this is a drive
Drive-reduction theory
Developed by Clark Hull; the primary motivation of all organisms is to reduce their drives
Hedonic principle
Developed by Aristotle; people are primarily motivated to experience pleasure and avoid pain
Capgras Syndrome
Damage to the connection between the temporal lobe and the limbic system causes the belief that loved ones are imposters due to lack of emotional connection
Maslow’s Hierarchy of Needs
physiological - safety - love and belonging - esteem - self actualization
When basic needs are met, autonomy and satisfaction with life increase. When basic needs are not met, autonomy makes little difference to quality of life
Orexigenic signals
Turn on when body has insufficient energy; lateral hypothalamus signals hormone ghrelin to release in stomach, switches on hunger
Anorixigenic signals
Ventromedial hypothalamus signals leptin to be released in fat cells, which makes food less rewarding; switched off hunger
Causes of eating disorders
- genetic
- experimental
- psychological
- cultural
Binge-eating disorder (BED)
Recurrent and uncontrolled episodes of eating a large number of calories in a short time
Bulimia nervosa
Binge eating followed by purging
Anorexia nervosa
Intense fear of being fat, resulting in severe restriction of food intake
Obesity
Defined by a BMI over 30
- causes biochemical abnormalities, eating without hunger, nature designing to overeat
- body resists weight loss
- dieting decreases metabolism
Evolutionary mismatch
Traits that were adaptive in an ancestral environment, but now may be maladaptive in a modern environment
How is the human body resistant to weight loss?
Weight gain causes an increase in size and number of fat cells in the body, whereas weight loss only decreases the size of the fat cells but not the total number of fat cells in the body
Dieting causes a decrease in metabolism, which makes the body even better at converting food to fat
DHEA (dihydroepiandosterone)
Hormone responsible for onset of sexual desire
Testosterone
Hormone more responsible for sexual desire in men, but also responsible in women
Estrogen
Hormone more responsible for sexual desire in women
Sexual response cycle
The stages of physiological arousal during sexual activity:
excitement -> plateau -> orgasm -> resolution -> refractory period
Intrinsic motivation
A motivation to take actions that are themselves rewarding (i.e. eating ice cream)
Extrinsic motivation
A motivation to take actions that lead to reward (i.e. brushing teeth)
Conscious motivation
Motivations of which people are aware
Unconscious motivation
Motivations of which people are not aware
Need for achievement
The motivation to solve worthwhile problems; an unconscious motivation
Approach motivation
The motivation to experience positive outcomes; promotion
Avoidance motivation
The motivation to avoid experiencing negative outcomes; prevention
- more powerful that approach motivation
- we take more risks to avoid loss than to add gain
Loss aversion
The tendency to care more about avoiding losses than achieving equal-size gains
Terror management theory
A theory about how people respond to knowledge of their own mortality
- developing a cultural worldview
- mortality-salience hypothesis
Mortality-salience hypothesis
The prediction that people who are reminded of their own mortality will work to reinforce their cultural worldviews
We are motivated to avoid death-related anxiety by working to achieve meaningful immortality through our legacies
Language
A system for communicating with other using signals that are combined according to rules of grammar and that convey meaning
Grammar
A set of rules that specify how the units of language can be combined to produce meaningful messages
How is human language difference from the signaling of other species?
- complex structure allows for a wide range of ideas and concepts with an infinite number of distinct sentences
- we describe intangible things
- we use language in thought to name, categorize, and describe things to ourselves
Phonemes
The smallest units of sound that are recognizable as speech rather than random noises
Phonological rules
Rules that indicate how phonemes can be combined to produce speech sounds
Morphemes
The smallest meaningful units of language; produced by combining phonemes
- content morphemes: things and events (cat, dog, take)
- function morphemes: grammatical functions and time indicators (and, or, but, when)
Morphological rules
Rules that indicate how morphemes can be combined to form words
Syntactic rules
Rules that indicate how words can be combined to form phrases and sentences
Fast mapping
The process whereby children map a word onto an underlying concept after only a single exposure
Telegraphic speech
Aka two-word speech/child speech; develops around 2 years old, is devoid of function morphemes and consists mostly of content words
Behaviorist theory of language learning
We learn language the same way we develop every skill; through reinforcement, shaping, extinction, and operant conditioning
Nativist theory of language learning
Language development is an innate, biological capacity aided by Chomsky’s universal grammar
Universal grammar
Developed by Noam Chomsky; a collection of processes that facilitate language learning and argue that children are born with mental structures that facilitate comprehension and production of language regardless of the ungrammatical structure of regular conversation
Interactionist theory of language learning
Infants are born with an innate ability to acquire language, but social interactions also play a crucial role
Genetic dysaphasia
Inability to learn the grammatical structure of language despite having otherwise normal intelligence
Aphasia
Difficulty in producing or comprehending language caused by and depending on damage to either Broca’s area (production) or Wernicke’s area (comprehension)
Six main characteristics of language development
- children learn language very quickly
- children make few speaking errors apart from overregularizing
- passive mastery develops faster than active mastery
- infants can distinguish between all human phonemes
- comprehension before production
- babbling adapts to native language
Effects of bilingualism
- no significant difference in language development
- increases gray matter
- some cognitive and executive functioning benefits
Linguistic relativity hypothesis
Language shapes the nature of thought
Concept
A mental representation that groups of categorizes shared features of related objects, events, or other stimuli
